Zoo siv
PentaYurchitol Tetraacetate, tseem hu ua tus tsiaj, yog ib qho tshuaj lom neeg muaj kuab lom nrog cov mis molecular c14h20o8. Nws yog cov khoom siv tawv, cov hmoov dawb uas yog soluble hauv cov khoom siv etetne thiab etetne thiab ethanol.pet yog ib qho kev sib txuas lus tseem ceeb hauv kev tsim cov txheej txheej thiab cov nplaum. Nws txhim kho lub hardness, durability, thiab tshuaj tua tsis tau ntawm cov ntaub ntawv no. Tus tsiaj kuj tseem siv tau los ua cov stabilizer thiab roj nplua nyeem hauv kev tsim cov polyvinyl chloride (PVC) plastics.Kev yog siv los ua cov tshuaj lom neeg, xws li Etresterifications thiab Transterests. Nws tseem tuaj yeem ua tus reagent rau kev tiv thaiv dej cawv rau hauv cov cawv uas muaj kev nyab xeeb uas muaj kev nyab xeeb, nws yuav tsum ua kom muaj kev noj qab haus huv.
