Abstract
The invention relates to a treatment method of a chemical waste liquid, in particular to a method for producing unsaturated polyester resin by mixing a fumaric acid by-product with organic acid. The method comprises the following steps of: a, evaporating a crude waste liquid, i.e., an organic acid waste liquid produced during production of fumaric acid with a tail gas washing liquid produced by using phthalic anhydride, concentrating, crystalizing and drying to obtain powdery mixed binary acid; b, reacting 40-100 parts by weight of mixed binary acid, 40-100 parts by weight of dihydric alcohol or trihydric alcohol or pentaerythritol at the reaction temperature of 10-100 DEG C for hours, removing small molecular water produced in a reaction and excessive dihydric alcohol by adopting a vacuumizing method; and c, mixing a performed polymer with 20-60 parts by weight of styrene and 1 part by weight of initiator, and polymerizing into unsaturated polyester resin at the normal temperature. According to the method, a fumaric acid production waste liquid can be recycled, so that discharge pollution is lowered, the treatment cost is low, and the preparation cost of the unsaturated polyester resin can be lowered.
Description
Technical field
The present invention relates to a kind of treatment process of chemical waste liquid, specifically is a kind of method of producing unsaturated polyester resin with fumaric acid sub product mixed organic acid.
Background technology
A kind of prior preparation method of fumaric acid is (wherein the massfraction of maleic acid is about 77.15%) adding catalyzer thiocarbamide (SC (NH in the tail gas washing lotion that phthalic anhydride is produced
2)
2), make wherein maleic acid isomerization reaction generate fumaric acid.In this technology, gained filtrating promptly is fumaric acid sub product mixed organic acid solution after filtering separation fumaric acid solid.Mainly contain phenylformic acid, phthalic acid, maleic acid, fumaric acid etc. in the sub product mixed organic acid solution.Total acid content about 21.60% in the raffinate wherein according to one's analysis; In the total acid content that it comprised, unsaturated binary olefin(e) acid accounts for 55-75%, and the diprotic acid total amount accounts for 95-97%.Traditionally, this filtrating is used as in the waste water and discharging, not only processing cost is high and cause exhaust emission for it.
In addition; Usually become unsaturated polyester resin with diprotic acid and divalent alcohol (or trivalent alcohol, tetravalent alcohol) polycondensation in the prior art, its hardness is equally matched with marble hardness, is usually used in making the kitchen cabinet lining; Decorative fabric or artistic sculpture artwork etc., but its material cost is higher.
Summary of the invention
Technical problem to be solved by this invention is; Providing a kind of can produce waste liquid to fumaric acid and recycle; Reduce entering pollution, processing cost is low, and can reduce the method with fumaric acid sub product mixed organic acid production unsaturated polyester resin of unsaturated polyester resin manufacturing cost.
Method with fumaric acid sub product mixed organic acid production unsaturated polyester resin of the present invention is:
A. producing the organic acid waste liquid that fumaric acid was produced with the tail gas washing lotion of phthalic anhydride production is the raw material waste liquid, and binary olefin(e) acid weight accounts for 55-75% in the total acid content of raw material waste liquid, and the diprotic acid gross weight accounts for 95-97%; The raw material waste liquid through evaporation, concentrate, obtain the powdered mixed dibasic acid after the crystallization, oven dry;
B. get above-mentioned mixed dibasic acid 40-100 part by weight; Divalent alcohol or trivalent alcohol or tetramethylolmethane 40-100 part; Behind temperature of reaction 10-100 ℃ stoichiometric number hour, adopt the method that vacuumizes to slough micromolecular water that reaction generates and excessive divalent alcohol, reaction obtains performed polymer;
C. above-mentioned performed polymer is mixed with the vinylbenzene of 20-60 weight part and the initiator of 1 weight part, aggregate into unsaturated polyester resin at normal temperatures.
Described divalent alcohol is a kind of or several mixing in terepthaloyl moietie, Ucar 35, butyleneglycol, pentanediol, Diethylene Glycol, dihydroxyphenyl propane, the tetrahydrochysene dihydroxyphenyl propane.
The present invention produces waste liquid with fumaric acid and is prepared into the unsaturated polyester resin with higher utility value, has reduced treatment cost of waste liquor, has reduced exhaust emission; Simultaneously; The unsaturated polyester resin of this method preparation has unique chemical stability and heat-resistant stability; This kind resin is assessed through chemistry, at high temperature (100 ℃ even higher), anti-various chemical corrosions; Acidity and alkaline aqueous solution (like sodium hydroxide, hydrochloric acid, sulfuric acid, yellow soda ash and nitric acid) and oxygenant effect are difficult for down degrading, and can be used for making artificial marble or granite.
Embodiment
It is the raw material waste liquid that the present invention produces the organic acid waste liquid that fumaric acid was produced with the tail gas washing lotion of phthalic anhydride production, and binary olefin(e) acid weight accounts for 55-75% in the total acid content of raw material waste liquid, and the diprotic acid gross weight accounts for 80-97%; The raw material waste liquid through evaporation, concentrate, obtain the powdered mixed dibasic acid after the crystallization, oven dry; With this mixed dibasic acid and divalent alcohol or trivalent alcohol or tetramethylolmethane, behind temperature of reaction 10-100 ℃ stoichiometric number hour, adopt the method that vacuumizes to slough micromolecular water that reaction generates and excessive divalent alcohol, reaction obtains performed polymer; The initiator of performed polymer with vinylbenzene and 1 weight part mixed, aggregate into unsaturated polyester resin at normal temperatures.The detected result of specific embodiment and final product such as following table:
