Abstract

The invention relates to a preparation method of a binary acid refined adsorbing material. According to the preparation method, co-monomers, namely beta-myrcene, vinyl methyl silicone (diol) diacetate and N,N-methylene bisacrylamide, are added into vinylidene chloride, a dispersing aid (methyl vinyl ether copolymerized maleic acid) is added to generate a polymer, and the polymer is utilized for extracting decolored binary acid with a long carbon chain. The preparation method has the advantages that the adsorbing capacity is high, and the loss of binary acid caused by the repeated crystallization and filtration can be reduced.

Description

technical field [0001] The invention relates to a product refining method, in particular to a preparation method of a dibasic acid refined adsorption material. 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 acid from glucose.
