Succininate plays lub luag haujlwm hauv cov citric acid voj voog, kev ua piv txwv txog cov txheej txheem. Lub npe muab nyiaj los ntawm Latin succinum, lub ntsiab lus Amber, los ntawm cov uas cov kua qaub yuav tau txais.
Succinic acid yog ua ntej ua ntej rau qee cov polyesters tshwj xeeb. Nws yog tseem muaj qee cov txheej txheem alkyd.
Succinic acid tau zam nyob rau hauv cov zaub mov thiab dej haus kev lag luam, feem ntau yog cov kev tswj hwm acidity. Kev kwv yees generadroduction yog kwv yees li ntawm 16,000 txog 30,000 tonnes ib xyoos, nrog tus nqi ntawm 10%. Txoj kev loj hlob tuaj yeem raug ntaus nqi mus rau kev nce qib hauv kev ua haujlwm hauv kev siv tshuaj lom neeg uas nrhiav cov tshuaj tua hluav taws xob hauv kev siv tshuaj. Cov tuam txhab xws li Biomadia, myriant, Basf thiab Purac antpressing los ntawm kev ua qauv qhia kev lag luam ntawm bio-bascinic accminic acid mus rau kev lag luam acciable.
Nws kuj tseem tau muag asa cov zaub mov ntxiv thiab kev noj haus ntxiv, thiab feem ntau pom zoo raws li kev siv rau Asmeskas cov khoom noj thiab tshuaj. Raws li cov khoom lag luam tsis zoo nyob rau hauv cov khoom lag luam acidity thiab, ntau tsis tshua muaj txiaj ntsig, tsis muaj txiaj ntsig zoo.
