Daim ntawv thov:

Polyester resin synthesis: Octadecanedioic acid yog dav siv los ua ib qho ntawm cov khoom siv raw rau polyester cob. Nws tuaj yeem cuam tshuam nrog cawv xws li ethylene glycol los ua polyester, uas yog siv los tsim cov txheej, yas, fibers, thiab hluavtaws fibers.

Dye synthesis: Nyob rau hauv daim teb ntawm dyes, octadecanedioic acid yuav siv tau los ua ib qho nruab nrab rau cov synthesis ntawm organic pigments thiab dyes.
Nws yog siv rau hauv cov khoom lag luam xws li ncuav qab zib, khoom qab zib, thiab chocolates.

 

Yam ntxwv:
Octadecanedioic acid, tseem hu ua octanoic acid lossis fatty acid. Nws yog xim tsis muaj xim lossis daj me ntsis crystalline khoom.

Octadecanedioic acid yog cov organic compound nrog ob pawg carboxyl (- COOH) ua haujlwm. Nws yog ib hom dicarboxylic acid nrog acidity. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether, thiab benzene, tab sis yuav luag insoluble hauv dej.

Ntxiv rau nws cov khoom siv lub cev, octadecanedioic acid kuj muaj qee yam tshuaj lom neeg. Nws tuaj yeem cuam tshuam nrog amines los tsim cov aliphatic diacid amides, xws li octanediamide (C18H36CONH2). Nws kuj tuaj yeem ua rau muaj cawv los tsim cov roj esters sib xws, xws li octyl octanoate (C18H36O2+C8H18O → C18H36O2C8H18+H2O).
Nws kuj tuaj yeem siv los ua ke rau lwm cov tebchaw, xws li polyesters, polyamides, thiab dye intermediates.
