(r)-lactate ma le cas 10326-41-7
D-lactic acid o se vailaʻau. Ole fua ole mole ole C3H6O3. O le D-lactic acid 90% ose maualuga opitika (chiral) lactic acid e gaosia e le biological fermentation technology e faʻaogaina ai gaʻo e pei o le suka e fai ma mea mata. O le oloa maeʻa o le D-lactic acid o se vai e leai se lanu poʻo samasama samasama manino ma sina tofo oona; e hygroscopic, ma o le vaifofo o lo'o fa'aalia ai se tali fa'afefete. E mafai ona fa'afefiloi saoloto i le vai, ethanol po'o le eter, ma e le mafai ona solu ile chloroform.

E masani ona faʻaaogaina i le gaosiga ma le gaosiga o mea polylactic acid ma le tuʻufaʻatasia o vailaʻau faʻamaʻi ma vailaʻau faʻamaʻi.
Chiral compounds
Lactic acid esters e faʻaaoga ai le D-lactic acid e pei o mea mataʻutia o loʻo faʻaaogaina lautele i le gaosiga o mea manogi, faʻapipiʻi resini faʻapipiʻi, faʻapipiʻi ma lomitusi vaitusi, faʻapea foʻi i le faʻamamaina o paipa suauu ma pisinisi eletise. Faatasi ai ma i latou, o le D-methyl lactate e mafai ona faʻafefiloi tutusa ma le vai ma soʻo se polar solvents, e mafai ona faʻamaʻapeina atoatoa le nitrocellulose, cellulose acetate, cellulose acetobutyrate, ma isi ma le tele o polymers synthetic polar, ma o loʻo i ai se mea faʻafefe. O se solvent sili ona lelei ma le maualuga o le vevela ona o lona lelei o le maualuga o le vevela ma le faʻagesegese o le faʻafefe. E mafai ona faʻaaogaina e avea o se vaega o solu fefiloi e faʻaleleia ai le galue ma le solubilization. E le gata i lea, e mafai foi ona faʻaaogaina e avea o se mea mataʻutia mo vailaʻau, vailaau faʻamaʻi ma precursors mo le faʻapipiʻiina o isi mea faʻapipiʻi chiral. , Intermediate.
mea fa'aleagaina
Lactic acid o le mea mata'utia mo le bioplastic polylactic acid (PLA). O mea faʻaletino o mea PLA e faʻalagolago i le tuʻufaʻatasia ma mea o loʻo i totonu o D ma L isomers. O le racemate D, L-polylactic acid (PDLLA) faʻapipiʻiina mai le racemic D, L-lactic acid o loʻo i ai se fausaga amorphous, ma o ona mea faʻainisinia e le lelei, o le taimi faʻaleagaina e puupuu, ma faʻaitiitia ai le tino, faʻatasi ai ma le faʻaitiitia o le fua o le. 50%. % pe sili atu, o le talosaga e faʻatapulaʻaina. Ole vaega ole filifili ole L-polylactic acid (PLLA) ma le D-polylactic acid (PDLA) e masani ona faʻatulagaina, ma o latou tioata, malosi faʻainisinia ma le faʻafefeteina e sili atu le maualuga nai lo le PDLLA.
