L-Tartaric acid yog xim tsis tshua muaj xim los yog ib lub pob txha, los yog xim dawb, nplaum nplaum, crystalline hmoov. Nws yog tsw, muaj ib qho kua qaub, thiab nyob ruaj ruaj hauv pa.
Tartaric acid yog dav siv ua acidulant hauv dej haus thiab lwm yam khoom noj. Nrog nws cov kev ua qhov muag, L-Tartaric acid yog siv tshuaj ua kua tshuaj los daws DL-amino-butanol, ib nrab rau cov tshuaj antitubercular. Thiab nws yog siv chiral pas dej ua ke coj los ua ke cov khoom sib tw derivate.
Nrog nws cov acidity, nws yog siv raws li catalyst nyob rau hauv daim ntawv txheeb ntawm polyester ntaub los yog pH nqi regulator nyob rau hauv oryzanol qhuav.
Nrog nws lub cev, L-Tartaric acid yog siv hauv electroplating, sulfur tshem tawm thiab acid pickling. Nws kuj yog siv los ua tus neeg muag khoom, tus neeg quav tshuaj ntsuam xyuas khoom noj los yog tus neeg sawv cev hauv tshuaj tsom xam thiab tshuaj xyuas kev tshuaj ntsuam, los yog thaum tus neeg sawv cev tawm hauv kev dyeing.
Nrog nws txo, nws yog siv raws li reductive tus neeg sawv cev hauv kev tsim iav chemically los yog imaging agent nyob rau hauv photography. Nws tuaj yeem ua nrog cov hlau ion thiab siv tau los ua tus tu neeg los yog polishing tus neeg ntawm hlau nto.
