Succinic Acid | 110-15-6 : kuv
Khoom Description
Succinic acid (/səkˈsɪnɨk/; IUPAC systematic lub npe: butanedioic acid; keeb kwm hu ua ntsuj plig ntawm amber) yog ib tug diprotic, dicarboxylic acid nrog tshuaj formula C4H6O4 thiab structural formula HOOC-(CH2) 2-COOH. Nws yog awhite, odorless khoom. Succinate plays lub luag haujlwm hauv lub voj voog citric acid, anenergy-yielding txheej txheem. Lub npe muab los ntawm Latin succinum, lub ntsiab lus amber, los ntawm cov kua qaub uas yuav tau txais.Succinic acid yog ib qho ua ntej rau qee cov polyesters tshwj xeeb. Nws tseem yog ib feem ntawm qee cov alkyd resins.
Succinic acid yog siv rau hauv kev lag luam khoom noj khoom haus thiab dej haus, feem ntau ua cov kua qaub regulator. Kev tsim khoom thoob ntiaj teb yog kwv yees li ntawm 16,000 txog 30,000 tonnes hauv ib xyoos, nrog rau kev loj hlob txhua xyoo ntawm 10%. Kev loj hlob tuaj yeem raug ntaus nqi los ntawm kev nce qib hauv kev lag luam biotechnology uas nrhiav kev tshem tawm cov tshuaj lom neeg hauv kev lag luam. Cov tuam txhab xws li BioAmber, Reverdia, Myriant, BASF thiab Purac tau nce qib los ntawm kev ua qauv qhia kev tsim tawm ntawm bio-based succinic acid rau kev lag luam.
Nws tseem raug muag raws li cov khoom noj ntxiv thiab cov khoom noj ntxiv, thiab feem ntau lees paub tias muaj kev nyab xeeb rau cov neeg siv los ntawm US Food and Drug Administration. Raws li cov khoom lag luam inpharmaceutical excipient nws yog siv los tswj acidity thiab, tsis tshua muaj, cov ntsiav tshuaj ineffervescent.
