Abstract

This invention relates to one kind of method to use abandoned grease to produce epoxy plasticizer, its characteristic lies in: Use the abandoned grease as raw materials, by pretreatment, the obtainedglycerin ester to ester exchange respond with the methyl alcohol under alkali catalysis, then get fatty acidmethyl ester, then again with the peroxide organic acid, which is the reaction products ofhydrogen peroxide and organic acid, to directly epoxy respond, get the raw epoxy fatty acid methyl ester, then wash off the acid by water, and obtain the epoxy fatty acid methyl ester by distillationand dehydration product. The raw material cost of this invention is low, originates broadly, conforms to the green environmental protection requirement, and the craft is simple, does not pollute environment, so it is the good substitute of petroleum product.

Description

technical field

[0001] The invention relates to a production method of a plasticizer, in particular to a method for producing an epoxy plasticizer by using waste oil. It belongs to the technical field of organic chemical synthesis. Background technique

[0002] Plasticizers account for about 58% of the chemical additives market, and their specific products include phthalates (DOP), aliphatic dibasic esters, phosphate epoxy compounds, trimellitates, petroleum esters, Chlorine plasticizers, polymeric plasticizers, etc. At present, the annual consumption of plasticizers is very large. With the development of the plastics and rubber industries, the market demand is on the rise. Most of the above-mentioned plasticizers contain benzene rings, which are toxic and difficult to degrade. During use or production, they will cause harm to the environment and health, and the scope of use is limited. So far, there are few non-toxic and environmentally friendly plasticizers, accounting ...
