L(+)-Tartaric Acid | 87-69-4
IiNkcazo zeeMveliso
I-L (+) -i-Tartaric acid ayinambala okanye i-crystals eguquguqukayo, okanye imhlophe, i-granular, i-crystalline powder. Ayinavumba, inencasa yeasidi, kwaye izinzile emoyeni.
L (+) -Tartaric acid isetyenziswa ngokubanzi njenge acidulant kwisiselo kunye nokunye ukutya. Ngomsebenzi wayo we-optical, i-L (+) -i-Tartaric acid isetyenziswe njenge-agent yokuxazulula iikhemikhali ukusombulula i-DL-amino-butanol, i-intermediate ye-antitubercular drug. Kwaye isetyenziswa njengechibi le-chiral ukudibanisa izinto eziphuma kwi-tartrate. Nge-acidity yayo, isetyenziswe njenge-catalyst ekugqityweni kwe-resin ye-polyester ilaphu okanye umlawuli wexabiso le-pH kwimveliso ye-oryzanol. Ngobunzima bayo, i-L (+) -i-Tartaric acid isetyenziselwa i-electroplating, ukususwa kwesulfure, kunye ne-acid pickling. Ikwasetyenziswa njenge-ejenti eyinkimbinkimbi, i-ejenti yokuhlola izongezo zokutya okanye i-agent ye-chelating kuhlalutyo lweekhemikhali kunye nokuhlolwa kwamachiza, okanye njenge-ejenti yokuchasa ekudayeni. Ngokuncitshiswa kwayo, isetyenziswa njenge-arhente yokunciphisa kwimveliso yesipili ngokwekhemikhali okanye i-agent ye-imaging kwifoto. Iyakwazi ukuntsonkotha kunye ne-ion yensimbi kwaye ingasetyenziselwa njenge-arhente yokucoca okanye i-agent ye-polish ye-metal surface.
Isicelo
Ishishini lokutya
-Njengokwenza iasidi kunye nesigcinakaliso sendalo semarmalade, i-ayisikrimu, iijeli, iijusi, izigcini kunye neziselo.
– Njengeeffervescent kumanzi carbonated.
- Njenge-emulsifier kunye ne-preservative kwishishini lokwenza isonka kunye nokulungiswa kweelekese kunye neelekese.
Oenology: Isetyenziswa njenge acidifier. Isetyenziswa kwi musts kunye ne wayini ukulungisa iwayini ezilungelelanisiweyo ngokwembono yencasa, isiphumo ibe kukunyuka kweqondo le asidi kunye nokuhla komthamo we pH.
Ishishini lezinto zokuthambisa :Isetyenziswa njengenxalenye esisiseko kwiikhrimu ezininzi zendalo zomzimba.
