    MAIN nuj nqi THIAB HOM PHIAJ:

    L (+) - tartaric acid yog dav siv raws li acidulant nyob rau hauv dej haus, thiab lwm yam khoom noj, xws li dej qab zib, kua txiv hmab, khoom qab zib, khob cij thiab ib co colloidal sweetmeats. Nrog nws cov kho qhov muag ua si, L (+) - tartaric acid yog siv raws li cov tshuaj daws neeg sawv cev los daws DL-amino-butanol, ib nrab rau antitubercular tshuaj. Thiab nws yog siv raws li chiral pas dej ua ke los ua ke tartrate derivatives. Nrog nws cov acidity, nws yog siv raws li catalyst nyob rau hauv lub cob finishing ntawm polyester ntaub los yog pH nqi regulator nyob rau hauv oryzanol ntau lawm. Nrog nws cov complexation, L (+) - tartaric acid yog siv nyob rau hauv electroplating, sulfur tshem tawm thiab acid pickling. Nws kuj yog siv raws li complexing neeg sawv cev, soj ntsuam kuaj tus neeg saib xyuas los yog chelating neeg sawv cev nyob rau hauv cov tshuaj tsom xam thiab kws soj ntsuam, los yog raws li thaum nws tus neeg saib xyuas nyob rau hauv dyeing. Nrog nws cov yuav txo tau, nws yog siv raws li reductive neeg sawv cev nyob rau hauv raug daim iav sib los yog duab neeg sawv cev nyob rau hauv photography. Nws tseem complex nrog hlau ion thiab yuav siv tau raws li tu neeg sawv cev los yog polishing neeg sawv cev ntawm cov hlau nto.
