Abstract
The invention relates to a production method of epoxidized fatty acid methyl ester/epoxidized soybean oil. The production method concretely comprises the following technological steps: (1) taking one of soybean oil and fatty acid methyl ester, formic acid and hydrogen peroxide and preheating them to 90+/-2 DEG C; and (2) adding preheated soybean oil, formic acid and hydrogen peroxide into a pipeline reactor to react until the end of the reaction. According to the invention, by the utilization of the pipeline reactor, the technical bias that a high concentration of hydrogen peroxide cannot be used in a traditional epoxidized soybean oil production technology is overcome; by the use of 70% high concentration of hydrogen peroxide in the production process, the reaction time is greatly shortened, and the yield is substantially raised. In addition, by the use of a high concentration of hydrogen peroxide and a high proportion of formic acid, the reaction speed is fast, side reaction is less, epoxy value of the produced epoxidized soybean oil/epoxidized fatty acid methyl ester is remarkably raised, color is obviously improved, and transparency is better.
Description
Technical field
The present invention relates to a kind of production method of epoxy aliphatic acid methyl ester/epoxy soybean oil.
Background technology
Epoxy soybean oil is a kind of most popular nontoxic polyvinyl chloride softening agent stablizer of holding concurrently.Have good thermostability and light stability, water tolerance and oil-proofness are also good, can give the good physical strength of goods, weathering resistance and electrical property, and nontoxicity, are the chemical technology auxiliary agents that is used for packaging material for food of international population.The epoxy aliphatic acid methyl ester softening agent not only can replace the DOP softening agent to produce PVC product nontoxic, environmental protection wholly or in part, be used for food product pack, medical article material, toy and water supply line etc., simultaneously also as celluosic resin and elastomeric non-toxic plasticizer and tenderizer, in the processing of goods, adding epoxy aliphatic acid methyl ester can obviously improve the physicals of goods and extend digestion time, with metal(lic)stabilizer and used times such as barium, cadmium, zinc, good synergy is arranged.In addition, because it also has good oilness, consistency and dispersion performance, go back useful as surfactants and application of dispersant in production industries such as epoxy coating and epoxy resin
The most of raw material that adopts of the production process of at present domestic epoxy methyl esters/epoxy soybean oil adds reactor, be heated to drip hydrogen peroxide behind 50 ℃ of left and right, and the concentration of hydrogen peroxide is the raw material of 25～50%, 10 cubes, about 8 hours reaction times, because the reaction times is long, in reaction process side reaction is more, so the product oxirane value is not high, epoxy soybean oil 6.3 left and right, epoxy methyl esters 3.8 left and right, product color is poor partially yellow.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency, the production method of short, quantity-produced epoxy aliphatic acid methyl ester/epoxy soybean oil of a kind of reaction times is provided.
The technical scheme that realizes the object of the invention is a kind of production method of epoxy aliphatic acid methyl ester/epoxy soybean oil, specifically comprises following processing step: one of get in soybean oil and fatty acid methyl ester (1), formic acid, hydrogen peroxide are preheated to 90 ± 2 ℃; (2) will add through soybean oil, formic acid and the hydrogen peroxide of preheating pipeline reactor internal reaction to reaction to finish.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, the concentration of described hydrogen peroxide are 70%.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, the add-on of described formic acid are 6% of raw material total amount.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, the internal diameter of described pipeline reactor are 25 ~ 50mm.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, step (2) will be for adding the pipeline reactor internal reaction 10 minutes through soybean oil, formic acid and the hydrogen peroxide of preheating.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil: described step (1) one of is got in soybean oil and fatty acid methyl ester, formic acid, hydrogen peroxide are preheated to 90 ℃.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, described step (2) for volume pump with one of in soybean oil and fatty acid methyl ester, formic acid, hydrogen peroxide adds in pipeline reactor simultaneously.
The production method of above-mentioned epoxy aliphatic acid methyl ester/epoxy soybean oil, described pipeline reactor periphery has water-cooling jacket.
Reaction principle of the present invention is that hydrogen peroxide and formic acid reaction generate peroxyformic acid, and peroxyformic acid reacts with soybean oil again.
Reaction equation:
HCOOH+H
2O
2→HCOOOH+H
2O
The present invention has positive effect: (1) utilizes pipeline reactor to overcome the technology prejudice that can not adopt the high density hydrogen peroxide in traditional epoxy soybean oil production technique, use 70% high density hydrogen peroxide in production process, reaction times significantly shortens, and output significantly improves; (2) adopt hydrogen peroxide and a high proportion of formic acid of high density, speed of response is very fast, and side reaction is less, and the epoxy soybean oil of producing/epoxy aliphatic acid methyl ester oxirane value significantly improves, the color and luster aspect be improved significantly, its transparency is better.
