Definitions
- the present invention relates to a method for preventing adamantane from consolidating, and more particularly, to a method for preventing adamantane from consolidating when adamantane is stored or transported.
- Adamantane is generally used as an industrial chemical, particularly as a raw material for chemical products, medical chemicals, monomer bases for phototristologists, and the like, and has recently been in demand. Similar use is also expected for adamantane derivatives obtained by secondary processing of them.
- Such adamantane is synthesized using dicyclopentagen as a raw material and a Lewis acid such as aluminum chloride as a catalyst. Usually, it is washed in an organic solvent and then used as an industrial chemical in drums and paper bags. Shipment is distributed.
- adamantane has a melting point of 268 ° C, which is a high temperature. Since vapor pressure at room temperature is high, it has a sublimation property, and thus has a property of being easily consolidated during storage and transportation. Once consolidated, the agglomeration progresses firmly to the extent that the shape of the package is maintained, and the operability is significantly deteriorated. It has become a big problem among contractors. However, while the problem has been recognized, it has been distributed in a form including a consolidated state without effective means.
- a method of obtaining adamantane with less caking a method is disclosed in which adamantane powder is granulated by a roller compression method or a slug tableting method to suppress the growth of sublimate crystals and prevent agglomeration. (Patent Document 1).
- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-160517
- adamantane is a particle agglomerated with each other and becomes agglomerated with time, and solidifies in a drum for storage or a paper bag. Workability is extremely bad.
- An object of the present invention is to provide an adamantane having a stable quality in which particles do not aggregate and solidify.
- the present inventor has made the residual amount of the solvent contained in the product adamantane not more than a certain amount in the adamantane production process.
- the residual amount of the organic solvent used for the purification of adamantane is reduced to a certain amount or less in a short time, it is possible to obtain adamantane that does not cause any aggregation or solidification, and it is also possible to purify using a naphthenic solvent.
- the present invention provides the following adamantane caking prevention method.
- a method for preventing caking of adamantane characterized in that the amount of solvent contained in adamantane purified using a naphthenic solvent is 0.35% by mass or less.
- the boiling point of the solvent contained in adamantane is 150 ° C or less, and the amount of the solvent contained in adamantane is 0.3% by mass or less by drying within 60 minutes. Anti-caking method.
- a method for preventing caking of adamantane wherein the amount of solvent contained in adamantane purified using a solvent other than naphthenic solvent is 0.05% by mass or less.
- the boiling point of the solvent contained in adamantane is 150 ° C or less and the amount of the solvent contained in adamantane is 0.05% by mass or less by drying within 60 minutes.
- FIG. 1 is an explanatory diagram showing the behavior of a solvent in an aggregate of adamantane particles (referred to as ADM particles).
- the adamantane in the present invention is a solid product, and the shape thereof is not particularly limited, and examples thereof include a flake product, a pulverized product thereof, and a granular product.
- a fine powder having an average particle diameter of about 100 to 600 m can be suitably used.
- Adamantane is usually synthesized by hydrogenating dicyclopentagen to trimethylene norbornane and isomerizing it using an acidic substance such as aluminum chloride or hydrogen chloride as a catalyst.
- an acidic substance such as aluminum chloride or hydrogen chloride as a catalyst.
- endo-trimethylene norbornane which is a raw material of isomeric koji, and exo-trimethylene norbornane produced as a by-product remain in the manufactured product.
- a purification process by recrystallization is necessary in some cases. For this reason, the washing solvent or recrystallization solvent inevitably remains in the purified product of adamantane.
- this residual solvent further contributes to the aggregation of adamantanes having inherent sublimation properties.
- the amount of solvent contained in the product adamantane is 0.35% by mass or less when purified using a naphthenic solvent, and is 0.
- the adamantane is prevented from solidifying by setting the amount to not more than 05% by mass.
- the solvent remaining inside the adamantane particles is difficult to evaporate once the drying time is extended. After reaching a certain level of residual concentration, it hardly decreases after that. In other words, if adamantane is left to spontaneously evaporate under atmospheric pressure, it will only be removed from the surface and the solvent will remain at a high concentration overall.
- a solvent having a boiling point of 150 ° C. or less at normal pressure is used, and in the drying step, the residual amount of the solvent is 0.35% by mass or less or 0.05
- mass% By controlling to less than mass%, it is a so-called storage situation in which it does not agglomerate at the time of subsequent natural storage and is normally packed like a paper bag, and the pressure is naturally applied to the powder by the weight of the bag. Can obtain adamantane that does not solidify even under severe conditions.
- a solvent contained in adamantane that is, a solvent used for washing or recrystallization for purifying adamantane
- a solvent having a boiling point of 150 ° C or lower at normal pressure is preferable. Since the naphthenic solvent is similar in structure to adamantane, a part of the residual solvent is taken into the crystal, so that it seems difficult to consolidate even if the residual amount of the solvent is high.
- Naphthenic solvents are usually a mixture of C to C hydrocarbons, with 50
- Solvents other than naphthenic solvents are not particularly limited, but include aliphatic hydrocarbons such as pentane, hexane, and heptanes, aromatic hydrocarbons such as benzene and toluene, methanol, ethanol, propanol, butanol, and the like. The alcohols are used, and hexane and 2-propanol are preferably used.
- the amount of the solvent remaining in the product adamantane is 0.35% or less, preferably 0.30% by mass or less in the case of a naphthenic solvent, and 0.05 in the case of a solvent other than a naphthenic solvent. % Or less, preferably 0.04 mass% or less.
- the lower limit of the residual solvent amount is not particularly limited, but from the viewpoint of the drying operation, it is usually about 0.05% by weight in the case of naphthenic solvents, and is usually 0.005% by weight in solvents other than naphthenic solvents. Degree.
- an organic solvent having a boiling point of 150 ° C or less at normal pressure as described above is used.
- the solvent is removed and dried within 60 minutes under a pressure of 40 kPa or less under the following temperature conditions, and the amount of solvent remaining in the product adamantane is 0.30 mass in the case of a naphthenic solvent. % Or less, and in the case of a solvent other than naphthenic, it is preferably 0.04% by mass or less.
- adamantane powder has a strong adamantane powder that does not easily decrease after reaching a certain level of residual concentration even if the drying time in which the solvent remaining inside hardly evaporates is prolonged. If the solvent is removed rapidly (for example, under reduced pressure) within a short period of time, the residual solvent can be reduced in concentration. In other words, if the adamantane powder is left to spontaneously evaporate at atmospheric pressure, it will remain in the removal from the surface, and the solvent will remain at a high overall concentration. This will give adamantane powder that is hard to set.
- adamantane powder is an aggregate of adamantane particles (ADM particles), and the adamantane powder from the purification process is an aggregate in which a solvent is attached to the surface of the particles.
- ADM particles adamantane particles
- the adamantane powder from the purification process is an aggregate in which a solvent is attached to the surface of the particles.
- this adamantane powder is naturally dried at atmospheric pressure (that is, when not dried under reduced pressure)
- the surface of the adamantane powder is easily dried, but the solvent inside the powder remains.
- the particle surface inside the powder is in an equilibrium of “dissolved in a solvent” and “precipitation of solvent power”, and the particles are likely to aggregate.
- the solvent molecules that have remained on the surface will remain in the powder, become less likely to evaporate, and stay there, so the agglomerates bind more firmly. This is repeated and consolidation occurs.
- the solvent is efficiently evaporated from the inside of the adamantane powder at a low temperature. Therefore, the particles are dried in a state where the above-mentioned particles that are difficult to agglomerate are separated from each other inside the powder, so that the residual solvent remaining in the agglomerate is reduced and the powder is hard to consolidate. So in a short time, It can be understood how efficiently removing the solvent is important for preventing caking.
- adamantane purified products For transportation methods, keep the temperature conditions at 35 ° C or lower! /, And keep it in a stable state.
- the form of transportation and the shape of the container are not particularly problematic. However, during storage for a long period of time, it may be possible that air oxidation or the like may occur. Therefore, it is desirable to keep it in an atmosphere of nitrogen or other inert gas.
- adamantane mixed with an acidification inhibitor can be carried out without any restriction.
- the determination of the adamantane consolidation state was determined by placing 10 g of adamantane into a sonic sieving measuring device (Asahi Seisakusho Co., Ltd., Asahi Sonic Shifter A1) and placing it on a 850 m sieve. From the remaining situation, it was determined that the solidified state (O) when the residual amount was less than 5 g, and the solidified state (X) when the residual amount was 5 g or more.
