Abstract
A kind of production method of epoxy grease plasticizer.Be under the condition that does not add any solvent, make raw material with Oleum Gossypii semen or soybean oil, hydrogen peroxide, Glacial acetic acid and the vitriol oil with lower concentration, synthetic epoxy grease plasticizer under conditions such as certain temperature, time, proportioning, it is the softening agent that is used for polyvinyl chloride, in the polyvinyl chloride course of processing, do not produce toxic smog contaminate environment and injury human body.
Description
A kind of production method of epoxy grease plasticizer.
Technical field under the present invention is the synthetic of organic compound.
Before the present invention, in the suitability for industrialized production technology of synthesizing epoxy Oleum Gossypii semen and epoxy soybean oil, all use hydrogen peroxide, Glacial acetic acid and the sulfuric acid of high density and Oleum Gossypii semen or soybean oil as reactive material, most technologies need add certain solvent, as: benzene, acetone, ethyl acetate etc., so that reaction is easy to carry out.This method is produced epoxy Oleum Gossypii semen and epoxy soybean oil, often is subjected to the restriction in high density hydrogen peroxide source, moreover remaining in the product of being produced a spot of noxious solvent is arranged, caused in the polyvinyl chloride course of processing of using this product, produce toxic smog, contaminate environment, injury human body.
The present invention has proposed new technical scheme in order to overcome the deficiency of above-mentioned prior art.Purpose of the present invention just is to seek under the condition that does not add any solvent, Oleum Gossypii semen or soybean oil are carried out the novel process of epoxidation reaction with lower concentration hydrogen peroxide, Glacial acetic acid and the vitriol oil, shorten technology to reach, reduce cost the purpose of each factor of decontamination product.
In order to achieve the above object, the invention provides a kind of epoxy Oleum Gossypii semen of totally nontoxic and the production method of epoxy soybean oil.It is by adopting the hydrogen peroxide of lower concentration, condition such as proportioning raw materials such as hydrogen peroxide, organic acid and mineral acid and temperature of reaction, time in the conditioned reaction system, realized under the condition that no any solvent exists, with lower concentration hydrogen peroxide, Glacial acetic acid and the vitriol oil respectively with handle or untreated Oleum Gossypii semen or soybean oil are carried out the novel process of building-up reactions; The excess acid of ， Can Liu in system when reaction finishes neutralizes with the aqueous sodium carbonate of 1-30%.
Concrete grammar of the present invention is:
To Oleum Gossypii semen or soybean oil handling: with unpurified Oleum Gossypii semen or soybean oil, use the 2-40% aqueous sodium hydroxide solution, under 20-80 ℃, fully stir, carry out neutralizing treatment, then with centrifugal soap machine separating out fat acid sodium-salt and the moisture of taking off.
1, the epoxy Oleum Gossypii semen is synthetic:
To handle or 100 parts of undressed Oleum Gossypii semens hydrogen peroxide solution 50-85 part of 25-30%, Glacial acetic acid 10-30 part, vitriol oil 0.50-5 part in 35-70 ℃ temperature range, is fully stirred, epoxidation reaction was carried out 5-40 hour, and standing demix is told sour water.
Sodium carbonate solution with 1-30% neutralizes to above-mentioned system, uses 50-90 ℃ hot wash 2-6 time again, removes the moisture of Can Liu then with decompression.The oxirane value of the epoxy Oleum Gossypii semen that present method makes is between 4.0-5.5, and iodine number is below 6.
The epoxy Oleum Gossypii semen of producing in this way with its plastifying polyvinyl chloride test piece, records its mechanical property, transparency and heat aging performance, and the epoxy soybean oil of producing with prior art is suitable.
2, epoxy soybean oil is synthetic:
To handle or 100 parts of undressed soybean oil, hydrogen peroxide solution 60-95 part of 25-30%, Glacial acetic acid 10-30 part, vitriol oil 0.50-5 part in 35-70 ℃ of scope, is fully stirred, and epoxidation reaction was carried out 5-40 hour, and standing demix is told sour water.
Sodium carbonate solution with 1-30% neutralizes to above-mentioned system, uses 50-90 ℃ hot wash 2-6 time again, removes the moisture of Can Liu then with decompression.The oxirane value of the epoxy soybean oil that present method makes is between 6.0-7.0, and iodine number is below 6.
The epoxy soybean oil of producing in this way, with its plastifying polyvinyl chloride test piece, the epoxy soybean oil that records the production of its mechanical property, transparency and heat aging performance and prior art is suitable.
Show through toxicity test in order to prepared epoxy Oleum Gossypii semen of last method and epoxy soybean oil: the LD50 value:
Rat (oral)＞20ml/kg
Rabbit (subcutaneous injection)＞20ml/kg
Epoxy Oleum Gossypii semen and epoxy soybean oil are nontoxic softening agent of a class and stablizer, and their volatility is little, and resistance to migration is good, especially can improve light, the thermostability of polrvinyl chloride product; It is the softening agent that can be used for packaging material for food that a class is generally acknowledged.The production method of epoxy grease plasticizer of the present invention, advantage compared with the prior art is: prior art adopts the hydrogen peroxide of high density, and this raw material is subject to certain restrictions, the domestic production amount seldom, its production technique adopts solubilizing agent to promote reaction to carry out more; And production method of the present invention is to adopt the hydrogen peroxide of lower concentration, and abundant raw material need not add any solvent in the production process, thereby has obtained simplification technology, the technique effect that reduces cost; In the product that prior art is produced,, thereby caused in the polyvinyl chloride course of processing, emitting toxic smog because there is a small amount of noxious solvent, contaminate environment, the injury person, when using, then there are not these defectives in the product that the present invention produced.
