Nws yog tsuas yog siv nyob rau hauv kev ua thiab siv ntawm polylactic acid cov ntaub ntawv thiab cov synthesis ntawm chiral tshuaj thiab tshuaj tua kab intermediates.
Chiral compounds
Lactic acid esters siv D-lactic acid raws li raw cov ntaub ntawv yog dav siv nyob rau hauv zus tau tej cov naj hoom, hluavtaws resin coatings, nplaum thiab luam ntawv inks, thiab kuj nyob rau hauv kev tu cov roj av pipelines thiab hluav taws xob industries.Ntawm lawv, D-methyl lactate tuaj yeem sib tov sib xyaw nrog dej thiab ntau cov kuab tshuaj polar, tuaj yeem yaj tag nrho nitrocellulose, cellulose acetate, cellulose acetobutyrate, thiab lwm yam thiab ntau yam polar hluavtaws polymers, thiab muaj qhov melting point.Nws yog ib qho hnyav heev nrog kub kub taw tes vim nws qhov zoo ntawm qhov kub thiab txias thiab qeeb evaporation tus nqi.Nws tuaj yeem siv los ua ib feem ntawm cov kuab tshuaj sib xyaw los txhim kho kev ua haujlwm thiab solubilization.Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj, tshuaj tua kab thiab cov khoom ua ntej rau kev sib txuas ntawm lwm cov chiral compounds., Nruab nrab.
khoom degradable
Lactic acid yog raw khoom rau bioplastic polylactic acid (PLA).Lub cev lub cev ntawm cov ntaub ntawv PLA nyob ntawm seb muaj pes tsawg leeg thiab cov ntsiab lus ntawm D thiab L isomers.Cov racemate D, L-polylactic acid (PDLLA) synthesized los ntawm racemic D, L-lactic acid muaj cov qauv amorphous, thiab nws cov khoom siv tsis zoo, lub sij hawm degradation luv luv, thiab shrinkage tshwm sim hauv lub cev, nrog tus nqi shrinkage ntawm 50%.% lossis ntau dua, daim ntawv thov raug txwv.Cov saw ntu ntawm L-polylactic acid (PLLA) thiab D-polylactic acid (PDLA) tau teem caij tsis tu ncua, thiab lawv cov crystallinity, mechanical zog thiab melting point yog siab dua cov PDLLA.
