Problems solved by technology

[0004] Most of the factories do not have the ability to deal with organic solid waste, so they can only spend a lot of treatment costs. Please ask a qualified company to deal with it
This will lead to the waste of chemical product resources and the shrinking of factory profits

Abstract

The invention relates to a solid waste treatment method of ethyl pyruvate, and the method comprises the following steps: mixing solid waste containing sodium isocyanurate for producing ethyl pyruvatewith tap water, performing dissolving, and keeping the temperature at 50-70 DEG C for 4-5 hours to obtain a first mixture; adding a sodium hypochlorite solid into the first solution, and performing stirring for 6-10 hours at 50-70 DEG C to obtain a second mixture; cooling the second mixture to room temperature, and keeping stirring for 1.5-2 hours to obtain a third mixture; carrying out centrifugal drying on the third mixture to obtain a first solid product and centrifugal mother liquor; and employing the first solid product for preparing ethyl pyruvate. According to the solid waste treatmentmethod of ethyl pyruvate, provided by the invention, the solid waste generated in the production of ethyl pyruvate is chlorinated and oxidized again to become a reaction raw material with a reaction effect again, almost no harmful effect is caused to the environment, and the solid waste can continuously participate in the circulation of synthesizing ethyl pyruvate after harmless treatment, so theproduction cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of biochemical industry, in particular to a solid waste treatment method of ethyl pyruvate. Background technique [0002] Ethyl pyruvate (English ethyl pyruvate) is a colorless transparent liquid at room temperature, with a fresh, sweet aroma of flowers and fruits. It can be used in the deployment of apple, citrus, chocolate and other flavors. It is an extremely important organic synthesis intermediate , It is widely used in medicine (synthesis of thiamides), pesticides (herbicides, thiamides fungicides), food (used as preservatives, preservatives, etc.) and cosmetics. [0003] In the existing ethyl pyruvate synthesis technology, basically all are to utilize the catalytic oxidation of ethyl lactate to produce, utilize the specificity of TEMPO (tetramethylpiperidine nitrogen oxide) catalytic oxidation, and TCCA (three Chloroisocyanuric acid) is continuously oxidized to synthesize ethyl pyruvate. This product...
