Succinic acid
Succinic acid
Iasidi ye-Succinic (/səkˈsɪnɨk/; IUPAC igama elicwangcisiweyo: butanedioicacid; ngokwembali eyaziwa ngokuba ngumoya we-amber) yi-diprotic, dicarboxylic acidwith chemical formula C4H6O4 kunye ne-structural formula HOOC-(CH2)2-COOH.Imhlophe, ayinavumba eliqinileyo.I-Succinate idlala indima kumjikelezo we-citric acid, inkqubo yokuvelisa i-anenergy.Igama lisuka kwiLatin succinum, elithetha i-amber, apho i-asidi inokufunyanwa khona.
Iasidi yeSuccinic isandulela kwezinye iipolyester ezikhethekileyo.Ikwayinxalenye yezinye i-alkyd resins.
I-asidi ye-Succinic esetyenziswa kushishino lokutya kunye nesiselo, ikakhulu njengomlawuli we-asidi.I-Globalproduction iqikelelwa kwi-16,000 ukuya kwi-30,000 yeetoni ngonyaka, kunye nezinga lokukhula ngonyaka kwe-10%.Ukukhula kunokubalelwa kwinkqubela phambili kwi-industrial biotechnology efuna ukususa iikhemikhali ezisekwe kwipetroleum kwizicelo zemizi-mveliso.Iinkampani ezinje ngeBioAmber, iReverdia, iMyriant, iBASF kunye nePurac ziqhubela phambili ukusuka ekuboniseni isikali semveliso ye-bio-based succinic acid toviable commercialization.
Ikwathengiswa njengesongezo sokutya kunye nesongezo sokutya, kwaye yaziwa ngokubanzi njengekhuselekile kwezo zisetyenziswa yi-US Food and Drug Administration.Njengemveliso ye-excipient inpharmaceutical isetyenziselwa ukulawula i-asidi kwaye, ngokunqabileyo, iipilisi ezingenasiphelo.
