O le D-lactic acid o se vailaʻau. O le fua faʻatatau molecular o le C3H6O3. O le D-lactic acid 90% o se lactic acid maualuga optical (chiral) e gaosia e le tekinolosi faʻamaʻi faʻaola e faʻaaogaina ai carbohydrates e tutusa ma le suka o ni mea mata. O le oloa maeʻa o leD-lactic acido se vai e leai se lanu pe samasama māmā manino ma mafiafia e fai si oona; e hygroscopic, ma o le vai e iai sona tali atu oona. E mafai ona palu faatasi ma le vai, ethanol po'o le ether, ma e le mafai ona solo i le chloroform.

E faʻaaogaina tele i le faagasologaina ma le gaosia o mea polylactic acid ma le tuʻufaʻatasiga o vailaʻau chiral ma vailaʻau faʻasaina iniseti.
Fa'aputuga Chiral
O le lactic acid esters e faʻaaogaina ai le D-lactic acid o ni mea mata e faʻaaogaina lautele i le gaosiga o mea manogi, ufiufi resin faʻapitoa, mea faʻapipiʻi ma vaitusi lolomi, faʻapea foʻi i le faʻamamaina o paipa penisini ma pisinisi eletise. O nisi o ia mea, e mafai ona palu tutusa le D-methyl lactate ma le vai ma le tele o solvents polar, e mafai ona faʻataʻapeʻapeina atoa le nitrocellulose, cellulose acetates, cellulose acetobutyrate, ma isi mea faʻapitoa polar polymers, ma e iai le melting point. O se solvent sili ona lelei ma le maualuga o le boiling point ona o ona lelei o le vevela maualuga ma le saoasaoa o le faʻamamago. E mafai ona faʻaaogaina o se vaega o le solvent fefiloi e faʻaleleia atili ai le faigofie ona galue ma le solubilization. E le gata i lea, e mafai foʻi ona faʻaaogaina o se mea mata mo vailaʻau, vailaʻau faʻasaina ma precursors mo le faʻapipiʻiina o isi chiral compounds. , Intermediate.
mea e pala
O le lactic acid o le mea mata lea mo le bioplastic polylactic acid (PLA). O meatotino faaletino o meafaitino PLA e faalagolago i le tuufaatasiga ma le aofaʻi o D ma L isomers. O le racemate D, L-polylactic acid (PDLLA) na faia mai le racemic D, L-lactic acid e iai lona fausaga amorphous, ma e le lelei ona meatotino faʻainisinia, e puʻupuʻu le taimi e faʻaleagaina ai, ma e tupu le faʻaitiitia i le tino, faʻatasi ai ma le fua faatatau o le faʻaitiitia o le 50%. % pe sili atu, e faʻatapulaʻaina le faʻaoga. O vaega o le filifili o le L-polylactic acid (PLLA) ma le D-polylactic acid (PDLA) e faʻatulagaina masani, ma o latou crystallinity, malosi faʻainisinia ma le melting point e maualuga atu nai lo le PDLLA.
