Succinic acid
Succinic acid
Succinic acid (/səkˈsɪnɨk/; IUPAC systematic lub npe: butanedioicacid; keeb kwm hu ua ntsuj plig ntawm amber) yog diprotic, dicarboxylic acid nrog tshuaj formula C4H6O4 thiab cov qauv qauv 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 yuav tau txais.
Succinic acid yog ib qho ua ntej rau qee cov polyesters tshwj xeeb.Nws kuj yog ib feem ntawm qee cov alkyd resins.
Succinic acid yog siv nyob rau hauv cov khoom noj thiab dej haus kev lag luam, feem ntau raws li ib tug acidity 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 industrialbiotechnology uas nrhiav kev tshem cov tshuaj lom neeg hauv cov khoom siv hauv kev lag luam.Cov tuam txhab xws li BioAmber, Reverdia, Myriant, BASF thiab Purac tau nce zuj zus los ntawm kev ua qauv qhia kev tsim tawm ntawm bio-based succinic acid toviable lag luam.
Nws tseem raug muag asa zaub mov ntxiv thiab kev noj haus ntxiv, thiab feem ntau lees paub tias muaj kev nyab xeeb rau kev 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.
