Problems solved by technology

[0005] The currently disclosed refining of dibasic acid fermentation broth as raw material of bio-based nylon mainly uses decolorization resin or activated carbon column for decolorization, and then filters, crystallizes, and refilters after decolorization, resulting in more loss of dibasic acid, which needs to be improved

Abstract

Disclosed is preparation of an adsorbent of a long carbon chain biatomic acid fermentation solution. Copolymer monomer 1,3-pentadiene-1-carboxyl, diallyl maleate, 4-vinylpyridine-butyl acrylate and EGDMA are added into methyl acrylate polymerization, a polymer with a long carbon chain alkyl group and a diacid functional group on a skeleton is generated, and the adsorbent is used for extracting decolorized long carbon chain biatomic acid, has the advantage of high adsorption amount and can reduce losses of diacid brought by repeated crystallization and filtration.

Description

technical field [0001] The invention relates to an adsorbent for refined products, in particular to the preparation of an adsorbent for long carbon chain dibasic acid fermentation liquid. Background technique [0002] One of the most important prerequisites for the preparation of bio-based polyamide fibers is the synthesis of bio-based polyamides. In terms of research and development of bio-based polyamides, my country has independently developed 100% bio-based PA1010, which has become one of the most important engineering plastics in my country. The American company Verdezyne announced in 2010 that it had obtained yeast genetically engineered bacteria that can convert alkanes, vegetable oils, and sugars into adipic acid and put them into large-scale production. Under the premise that the market prospect of adipic acid is promising, Genommica also actively carried out the project of biosynthesis of adipic acid in the same year, and announced that it can synthesize adipic ac...
