I-D-lactic acid yikhemikhali. I-molecular formula yi-C3H6O3. I-D-lactic acid 90% yi-high optical (chiral) ye-lactic acid eveliswa bubuchwepheshe be-biological fermentation kusetyenziswa iicarbohydrates ezifana neswekile njengemathiriyeli ekrwada. Imveliso egqityiweyo ye-D-lactic acid yincindi engenambala okanye ekhanyayo etyheli ecacileyo enencasa emuncu; i-hygroscopic, kwaye isisombululo samanzi sibonisa ukusabela kwe-asidi. Inokuxutywa ngokukhululekileyo ngamanzi, i-ethanol okanye i-ether, kwaye ayinyibiliki kwi-chloroform.

Isetyenziswa kakhulu ekusetyenzweni nasekuveliseni izinto ze-polylactic acid kunye nokuhlanganiswa kwamachiza e-chiral kunye ne-pesticide intermediates.
Iikhompawundi zeChiral
I-Lactic acid esters isebenzisa i-D-lactic acid njengezinto eziluhlaza zisetyenziswa ngokubanzi kwimveliso yeziqholo, i-synthetic resin coatings, izinto zokuncamathelisa kunye nee-inki zokuprinta, kunye nokucocwa kwemibhobho yepetroleum kunye namashishini e-elektroniki. Phakathi kwazo, i-D-methyl lactate inokuxutywa ngokulinganayo ngamanzi kunye neentlobo ezahlukeneyo ze-polar solvents, inokunyibilika ngokupheleleyo i-nitrocellulose, i-cellulose acetate, i-cellulose acetobutyrate, njl. kunye neepolymers ezahlukeneyo ze-polar zokwenziwa, kwaye zinendawo yokunyibilika. Sisinyibilikisi esigqwesileyo esinendawo yokubilisa ephezulu ngenxa yoncedo lwaso lobushushu obuphezulu kunye nesantya esicothayo sokumka komphunga. Ingasetyenziselwa njengenxalenye ye-solvent edibeneyo yokuphucula ukusebenza kunye ne-solubilization. Ukongeza, inokuthi isetyenziswe njengesixhobo ekrwada kumayeza, izitshabalalisi kunye nezandulela zokwenziwa kwezinye iikhompawundi ze-chiral. , Phakathi.
izinto eziwohlokayo
I-lactic acid yimathiriyeli ekrwada ye-bioplastic polylactic acid (PLA). Iimpawu ezibonakalayo zezinto ze-PLA zixhomekeke ekubunjweni kunye nomxholo we-D kunye ne-L isomers. I-racemate D, i-L-polylactic acid (i-PDLLA) eyenziwe kwi-racemic D, i-L-lactic acid inesakhiwo se-amorphous, kwaye iimpawu zayo zomatshini zihluphekile, ixesha lokuthotywa lifutshane, kwaye ukuncipha kwenzeka emzimbeni, kunye nesantya sokuncipha. 50%. % okanye ngaphezulu, usetyenziso lulinganiselwe. Amacandelo amakhonkco e-L-polylactic acid (PLLA) kunye ne-D-polylactic acid (PDLA) zicwangciswa rhoqo, kwaye i-crystallinity yabo, amandla omatshini kunye nenqanaba lokunyibilika liphezulu kakhulu kune-PDLLA.
