D-Tartaric acid Siv thiab Synthesis
| Cov khoom siv tshuaj | Muaj peb stereoisomers ntawm tartaric acid: dextrose tartaric acid, levophyllic acid thiab meso tartaric acid. Kev sib hloov kho qhov muag ntawm qhov sib tov ntawm tib tus nqi ntawm dextrorotatory thiab levorotism yog kev sib koom ua ke, hu ua racemic tartaric acid. Lub mesomer tsis muaj nyob rau hauv qhov xwm txheej thiab tuaj yeem raug tshuaj lom neeg. Ntau yam tartaric acids yog cov xim tsis muaj kob uas yooj yim soluble hauv dej. |
| Siv |
D-(-)-Tartaric Acid cov hluavtaws enantiomer ntawm L-(+)-Tartaric Acid, siv nyob rau hauv kev npaj ntawm hluavtaws analgesics. tartaric acid yog qhov thib ob loj tshaj AHA hauv qhov loj (glycolic acid yog qhov tsawg tshaj plaws AHA thiab citric acid qhov loj tshaj plaws). Nws tsis nquag siv hauv tshuaj pleev ib ce lossis tshuaj tiv thaiv kev laus vim cov tshuaj formulators pom tias nws nyuaj rau kev ua haujlwm nrog thiab nws tuaj yeem ua rau tawv nqaij. D-(-)-Tartaric acid yog siv los ua tus neeg sawv cev daws teeb meem hauv cov organic synthesis. Nws yog siv los ua tus thawj coj rau kev npaj ntawm nws cov ester derivatives xws li D-tartaric acid diethyl ester, D-tartaric acid dimethyl ester thiab D-tartaric acid diiso-propyl ester. Nws pom daim ntawv thov nyob rau hauv cov synthesis ntawm chiral aziridine derivative, ib qho nruab nrab nruab nrab rau kev npaj ntawm hydroxyethylamine chav kawm HIV protease inhibitors viz. Raws li saquinavir, amprenavir thiab nelfinavir. Nws yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus raws li ib tug npias foaming neeg sawv cev, rau cov zaub mov acidity kev cai thiab raws li ib tug flavoring neeg sawv cev. |
