E masani ona faʻaaogaina i le gaosiga ma le gaosiga o mea polylactic acid ma le tuʻufaʻatasia o vailaʻau chiral ma vailaʻau faʻamaʻi.
Kiral compounds
Lactic acid esters o loʻo faʻaaogaina le D-lactic acid e pei o mea mataʻutia e faʻaaogaina lautele i le gaosiga o mea manogi, faʻapipiʻi resini faʻapipiʻi, faʻapipiʻi ma lomitusi lolomi, 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 faʻatasi ma le vai ma soʻo se polar solvents, e mafai ona faʻamavae atoa 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 ana 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.
