Dimer acid, feem ntau hu ua dimer fatty acid, yog ib qho kev sib xyaw ua ke uas muaj npe vim nws cov khoom tseem ceeb muaj ob pawg carboxylic acid. Nws yog tau los ntawm polymerizing unsaturated fatty acids xws li oleic acid thiab linoleic acid. Dimer acid muaj thermal stability zoo heev thiab tuaj yeem tswj tau qhov dej ntawm qhov kub thiab txias.
Nws tau siv dav hauv kev lag luam ntawm cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob, cov ntaub ntawv tsim hluav taws xob, cov khoom siv foob pob hluav taws, thiab lwm yam. High-purity dimer acid yog lub teeb daj viscous kua, thiab low-purity dimer acid yog cov kua dej liab-xim av. Nws feem ntau siv cov roj zaub ua cov khoom siv raw los ua kom muaj kev kub ntxhov thiab kev kub ntxhov nyob rau hauv qhov kev txiav txim ntawm lub catalyst kom tau cov khoom nyoos, thiab tom qab ntawd ua rau cov khoom siv molecular distillation kom tau txais cov khoom ntshiab.
