L(+)-I-Tartaric Acid | 87-69-4
Incazelo Yemikhiqizo
I-L(+)-I-Tartaric acid iyikristalu engenambala noma ekhanyayo, noma impushana emhlophe, ecolekile, ecwebezelayo. Ayinaphunga, inokunambitheka kwe-asidi, futhi izinzile emoyeni.
I-L(+) -I-Tartaric acid isetshenziswa kakhulu njenge-acidulant esiphuzweni nokunye ukudla. Ngomsebenzi wayo we-optical, i-L(+)-Tartaric acid isetshenziswa njenge-ejenti yokuxazulula amakhemikhali ukuze kuxazululwe i-DL-amino-butanol, okuphakathi komuthi we-antitubercular. Futhi isetshenziswa njenge-chiral pool ukuze kuhlanganiswe okuphuma kokunye kwe-tartrate. Nge-acidity yayo, isetshenziswa njenge-catalyst ekuqedweni kwe-resin kwendwangu ye-polyester noma isilawuli senani le-pH ekukhiqizeni i-oryzanol. Ngokuxutshwa kwayo, i-L(+)-Tartaric acid isetshenziswa ekufakeni i-electroplating, ekukhipheni isibabule, nasekukhetheni i-asidi. Ibuye isetshenziswe njenge-ejenti eyinkimbinkimbi, i-ejenti yokuhlola izithasiselo zokudla noma i-ejenti ye-chelating ekuhlaziyweni kwamakhemikhali nokuhlolwa kwemithi, noma njenge-ejenti yokumelana ekudayeni. Ngokuncishiswa kwayo, isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni isibuko ngamakhemikhali noma i-ejenti yokucabanga ezithombeni. Ingase futhi ibe yinkimbinkimbi nge-ion yensimbi futhi ingasetshenziswa njenge-ejenti yokuhlanza noma i-ejenti yokupholisha endaweni yensimbi.
Isicelo
Imboni Yokudla
- Njengesithako se-asidi nesilondolozi semvelo samamarmalade, u-ayisikhilimu, amajeli, amajusi, okokugcina kanye neziphuzo.
– Njengoba effervescent for amanzi carbonated.
- Njenge-emulsifier ne-preservative embonini yokwenza isinkwa nasekulungiseleleni amaswidi namaswidi.
I-Oenology: Isetshenziswa njenge-acidifier. Asetshenziswa kuma-must namawayini ukuze kulungiswe iwayini elilinganiselayo ngokubuka ukunambitheka, umphumela uba ukwanda kwezinga lawo le-asidi kanye nokuncipha kokuqukethwe kwawo kwe-pH.
Imboni Yezimonyo: Isetshenziswa njengengxenye eyisisekelo yamakhremu amaningi omzimba wemvelo.
