Abstract

The invention relates to a production method of epoxy plasticizer. Under the conditions of normal temperature, atmospheric pressure and mixing, ozone is introduced into a material which is capable of carrying out epoxidation and has unsaturated C=C bound till the epoxy value reach the needed degree and the epoxy plasticizer can be obtained; the material which is capable of carrying out epoxidation and has unsaturated C=C bound is chosen from one of natural oil, fatty acid monoester, tetrahydrophthalic ester and polybutene. The method has the advantages of short production process, easy operation, no complicate procedure of the original environment-protection process, relatively low cost and the like, thereby being worth of promoting and utilizing.

Description

The production method of epoxy plasticiser
Technical field
The present invention relates to a kind of production method of Chemicals, is a kind of production method of epoxy plasticiser specifically.
Background technology
Epoxy plasticiser is the compound that has epoxide group in molecular structure, in industrial polyvinyl chloride (PVC) RESINS processing industry, they not only have plastification to PVC, and can make the active chlorine atom on the polyvinyl chloride chain stable, epoxy machine group in the structure can absorb because of the light and the hydrogenchloride of coming out of degrading, thereby stoped the continuous Decomposition of PVC, played function of stabilizer, can play the work-ing life that prolongs goods.
Epoxy plasticizer toxicity is minimum, is best suited for the Plastic Packaging Materials of producing food, medicine, and epoxy plasticiser is used increasingly extensive in modern plastics industry.
The main raw material of producing epoxy plasticiser at present has: natural oil, fatty acid monoester, tetrahydrophthalic acid ester, polybutene etc.Work material has: hydrogen peroxide, formic acid, acetate, sulfuric acid, ion exchange resin etc.
Industrial process is raw material, formic acid (or acetate), hydrogen peroxide, catalyzer to be carried out epoxidation handle, and dewaters, filters through standing separation, neutralization washing, decompression stripping then, gets product.
The production of present epoxy plasticiser, it is longer to exist technological process, and temperature of reaction control requires high, problems such as the environmental protection treatment complexity of the acid of discharge, alkali wasteliquid, this also is to make the unhappy major cause of epoxy plasticiser development.
Summary of the invention
The purpose of this invention is to provide advantages such as short, easy to operate, the no complicated former environmental protection treatment operation of a kind of Production Flow Chart, cost be low relatively, the production method of the epoxy plasticiser that is worth of widely use.
The production method of epoxy plasticiser provided by the invention, it is under normal temperature and pressure and condition of stirring, but ozone is fed in the epoxidation raw material that has the two keys of unsaturated C, reaches required to oxirane value, can obtain epoxy plasticiser; But the described epoxidation raw material that has the two keys of unsaturated C is selected from tetrahydrophthalic acid ester, soybean oil, Oleum Gossypii semen, Zoomeric acid formicester or ricinolic acid methyl esters; Described oxirane value is 4~7%.
Described oxirane value size is decided as required, and its oxirane value of different raw materials is also different, usually, can satisfy basic need 4~7%.
Under the certain situation of raw material weight, the length in the concentration of ozone, flow decision reaction times unit time, because the ozone concn that common ozonizer generates is between 10~40mg/L, therefore can be according to the difference of raw material and the size of amount, the size reasonable of the oxirane value of the finished product epoxy plasticiser calculates the consumption of required ozone, thus the reasonable length of controlling reaction time.
Its mechanism is ozone chemistry molecular formula O 3, its bonding state is extremely unstable, can resolve into oxygen at normal temperatures and single oxygen is separated.Single oxidation character is extremely active, and its strong oxidizing property is easy to make by the C in the epoxy raw material pair of keys by epoxidation, produces the epoxy plasticiser product thereby reach.
Because ozone oxidation ability extra-heavy so epoxidation process need not to use formic acid or acetate to do carrier, need not add the ore deposit acid catalyst, can finish epoxidation process at normal temperatures and pressures, its oxirane value can reach the quality product requirement fully.
Because production process need not add materials such as acid, alkali, thus need not to carry out epoxidised subsequent handling, as neutralization washing dehydration, press filtration etc., so belong to CR production basically.
The present invention has advantages such as short, easy to operate, the no complicated former environmental protection treatment operation of Production Flow Chart, cost be low relatively, is worth of widely use.
Embodiment
Embodiment one: under normal temperature and pressure and condition of stirring, the 100Kg soybean oil is added in the reactor, feed the ozone that utilizes ozonizer to produce from reactor bottom, the concentration of ozone is 20mg/L, to oxirane value be 6.3%, stopped reaction can obtain the epoxy soybean oil production.

Claims (1)

1. the production method of an epoxy plasticiser is characterized in that under normal temperature and pressure and condition of stirring, but ozone is fed in the epoxidation raw material that has the two keys of unsaturated C, reaches required to oxirane value, can obtain epoxy plasticiser; But the described epoxidation raw material that has the two keys of unsaturated C is selected from tetrahydrophthalic acid ester, soybean oil, Oleum Gossypii semen, Zoomeric acid formicester or ricinolic acid methyl esters; Described oxirane value is 4~7%.
