Itaconic Acid Cas 97-65-4 Rau Surfactants
Itaconic acid tseem hu ua methylenesuccinic acid, methylene succinic acid. Nws yog ib qho unsaturated acid uas muaj conjugated ob daim ntawv cog lus thiab ob pawg carboxylic thiab raug ntsuas raws li ib qho ntawm 12 cov khoom muaj nqis ntxiv los ntawm biomass. Nws yog dawb crystalline hmoov los yog hmoov nyob rau hauv chav tsev kub, melting point yog 165-168 ℃, tshwj xeeb gravity yog 1.632, soluble nyob rau hauv dej, ethanol thiab lwm yam kuab tshuaj. Itaconic acid muaj cov khoom siv tshuaj lom neeg thiab tuaj yeem ua tiav ntau yam kev sib txuas ntxiv, cov tshuaj tiv thaiv esterification thiab cov tshuaj tiv thaiv polymerization.
