D-tartaric acidCAS147-71-7 ib ib ib ib ibDaim ntawv thov

Siv dav hauv kev lag luam khoom noj khoom haus, xws li npias foaming tus neeg saib xyuas, zaub mov qaub tus neeg sawv cev, tus neeg sawv cev flavoring, siv rau hauv cov dej qab zib, khoom qab zib, kua txiv hmab txiv ntoo, ntses, tais diav txias, ci hmoov, thiab lwm yam.

Tartaric acid yog dav siv los ua acidulant hauv dej haus thiab lwm yam khoom noj, zoo ib yam li citric acid. Siv ua ke nrog tannins, tartaric acid ua raws li ib tug mordant rau acid dyes, thiab kuj yog siv nyob rau hauv ib co kev txhim kho thiab kho cov hauj lwm nyob rau hauv lub photographic kev lag luam, thiab nws cov hlau ntsev yog photosensitizing, ua rau lawv pab tau nyob rau hauv blueprints. Tartaric acid tuaj yeem ua haujlwm nrog ntau yam hlau ions thiab tuaj yeem siv los ua tus neeg saib xyuas thiab polishing tus neeg sawv cev rau cov hlau nto. Potassium sodium tartrate (Luo Chemicalbook Plhaub ntsev) tuaj yeem siv los npaj Fehling's reagent, thiab tseem tuaj yeem siv rau hauv cov tshuaj ua laxative thiab diuretic, thiab tseem siv los ua ib qho nruab nrab ntawm Cincophen. Nws cov crystals muaj piezoelectric zog thiab tuaj yeem siv rau hauv kev lag luam hluav taws xob. Feem ntau yog siv rau hauv dej haus, khoom qab zib, qhob cij, gelatin li qaub neeg sawv cev, biochemical reagent, racemate splitting tus neeg saib xyuas, kws tshuaj splitting tus neeg saib xyuas. Kuj tseem siv tau hauv kev yees duab, kaus poom, luam ntawv thiab dyeing, cov tais diav thiab hauv kev npaj ntawm lwm cov tshuaj daws teeb meem thiab ntsev
