Problems solved by technology

[0005] Most of the existing dodecanedioic acid production or purification processes use activated carbon as the adsorbent, or instead of using the adsorbent, use more energy-consuming and more complex crystallization methods for purification. The production process is cumbersome, energy-consuming, and time-consuming.

Abstract

The invention provides a preparation method for a dodecanedioic acid purification material. The invention provides a preparation method for a dodecanedioic acid purification material. The preparationmethod comprises the following steps: adding poly(1-decene)hydride, 1,4-butanediol vinyl diether, tetrabutylammonium difluorotriphenylstannate, 3-trimethylsilyl-3-buten-2-one, 5-norbornene-2-methylvinyl ether, methyl-6-bromobenzo[D][1,3]dioxole-5-carboxylic acid methyl ester, benzoyl peroxide, nanometer calcium carbonate, water and gelatin into a reaction vessel, carrying out heating after uniformmixing under stirring, carrying out a reaction, and subjecting a reaction product to filtering, washing with water and drying successively so as to obtain the dodecanedioic acid purification material.

Description

technical field [0001] The invention relates to a preparation method of an adsorbent, in particular to a preparation method of a purification material for dodecanedioic acid. Background technique [0002] Dodecanedioic acid has good thermal stability and is a chemical raw material that can be used as a raw material for engineering plastic nylon 6-12; the ester formed with alcohols can be used as a plasticizer for plastics, jet engines and gas turbines Base oil for high-grade lubricating oil and grease; it can also be used as a modifier for saturated polyester, a precipitant for metals and spices, a raw material for special polyurethane, and a solute in the electrolyte of high-voltage aluminum electrolytic capacitors. [0003] CN104529747B discloses a method for purifying dodecanedioic acid. It belongs to the purification treatment of acyclic dicarboxylic acids with 12 carbon atoms. It is characterized in that the crude dodecanedioic acid produced by microbial fermentation ...
