    Ntchito yaikulu NDI CHOLINGA:

    L (+) - Tartaric asidi chimagwiritsidwa ntchito monga acidulant mu chakumwa, ndi zakudya zina monga zakumwa zoziziritsa kukhosi, vinyo, maswiti, mkate ndi sweetmeats colloidal. Ndi ntchito yake kuwala, L (+) - asidi Tartaric ntchito ngati mankhwala kuthetsa wothandizila kuthetsa DL-kwa amino-butanol, mungafike mankhwala antitubercular. Ndipo ntchito monga chiral dziwe lithe tartrate ofanana nawo. Ndi acidity wake, ntchito monga chothandizira mu utomoni kutsirizitsa poliyesitala nsalu kapena pH phindu yang'anira kupanga oryzanol. Ndi complexation ake, L (+) - asidi Tartaric ntchito electroplating, kuchotsa sulfure ndi asidi pickling. Amagwiritsidwanso ntchito ngati wothandizira complexing, kuphimba wothandizila kapena chelating wothandizila mankhwala kusanthula ndi mankhwala anayendera, kapena kukana wothandizila mu ankaudaya. Ndi kuchepetsa wake, ntchito ngati wothandizira reductive opangira galasi mankhwala kapena wothandizila kulingalira kujambula. Chitha komanso zovuta ndi ion zitsulo ndipo angagwiritsidwe ntchito monga kukonza wothandizila kapena kupukuta wothandizila padziko zitsulo.
