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 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 physical strength, weathering resistance and electrical property that goods are good, and nontoxicity, are the chemical technology auxiliary agents for packaging material for food of international population.Epoxy aliphatic acid methyl ester softening agent not only can replace DOP softening agent to produce PVC product nontoxic, environmental protection wholly or in part, 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 used times such as barium, cadmium, zinc, there is good synergy.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 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 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 object of the invention is to solve above-mentioned deficiency, the production method of short, quantity-produced 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 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) soybean oil through preheating, formic acid and hydrogen peroxide are added reaction to reaction in pipeline reactor finish.
The production method of above-mentioned epoxy soybean oil, the concentration of described hydrogen peroxide is 70%.
The production method of above-mentioned epoxy soybean oil, the add-on of described formic acid is 6% of raw material total amount.
The production method of above-mentioned epoxy soybean oil, the internal diameter of described pipeline reactor is 25～50mm.
The production method of above-mentioned epoxy soybean oil, step (2) is for to add the soybean oil through preheating, formic acid and hydrogen peroxide in pipeline reactor and to react 10 minutes.
The production method of above-mentioned 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 soybean oil, described step (2) for volume pump by 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 soybean oil, described pipeline reactor periphery has water-cooling jacket.
Reaction principle of the present invention is that hydrogen peroxide reacts generation peroxyformic acid with formic acid, and peroxyformic acid reacts with soybean oil again.
Reaction equation:
The present invention has positive effect: (1) utilizes pipeline reactor to overcome the technology prejudice that can not adopt high density hydrogen peroxide in traditional epoxy soybean oil production technique, in production process, use 70% high density hydrogen peroxide, 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 epoxy soybean oil/epoxy aliphatic acid methyl ester oxirane value of producing significantly improves, color and luster aspect be improved significantly, its transparency is better.
