D-lactic acid yog ib yam tshuaj lom neeg. Cov mis molecular yog C3H6O3. D-lactic acid 90% yog ib qho lactic acid uas muaj zog heev (chiral) uas tsim los ntawm kev siv tshuab biological fermentation siv cov carbohydrates zoo li qab zib ua cov khoom siv raw. Cov khoom tiav ntawmD-lactic acidyog ib qho kua tsis muaj xim lossis daj daj ntshiab uas muaj qhov saj me ntsis qaub; nws yog hygroscopic, thiab cov kua dej ua rau muaj kev cuam tshuam acidic. Nws tuaj yeem sib xyaw nrog dej, ethanol lossis ether, thiab tsis yaj hauv chloroform.

Nws yog siv rau hauv kev ua thiab tsim cov khoom siv polylactic acid thiab kev tsim cov tshuaj chiral thiab cov tshuaj tua kab intermediates.
Cov tshuaj chiral
Cov lactic acid esters siv D-lactic acid ua cov khoom siv raw yog siv dav hauv kev tsim cov tshuaj tsw qab, cov tshuaj pleev xim hluavtaws, cov nplaum thiab cov kua luam ntawv, thiab tseem siv rau kev ntxuav cov kav dej roj thiab kev lag luam hluav taws xob. Ntawm lawv, D-methyl lactate tuaj yeem sib xyaw nrog dej thiab ntau yam polar solvents, tuaj yeem yaj tag nrho nitrocellulose, cellulose acetate, cellulose acetobutyrate, thiab lwm yam thiab ntau yam polar synthetic polymers, thiab muaj lub ntsiab lus yaj. Nws yog cov kuab tshuaj zoo heev nrog lub ntsiab lus kub siab vim nws qhov zoo ntawm qhov kub siab thiab qeeb qeeb evaporation. Nws tuaj yeem siv ua ib feem ntawm cov kuab tshuaj sib xyaw los txhim kho kev ua haujlwm thiab solubilization. Tsis tas li ntawd, nws kuj tuaj yeem siv ua cov khoom siv raw rau tshuaj, tshuaj tua kab thiab cov khoom ua ntej rau kev tsim cov tshuaj chiral. , Nruab Nrab.
cov khoom uas lwj tau
Lactic acid yog cov khoom siv raw rau bioplastic polylactic acid (PLA). Cov khoom siv lub cev ntawm PLA cov ntaub ntawv nyob ntawm qhov sib xyaw thiab cov ntsiab lus ntawm D thiab L isomers. Lub racemate D, L-polylactic acid (PDLLA) synthesized los ntawm racemic D, L-lactic acid muaj cov qauv amorphous, thiab nws cov khoom siv kho tshuab tsis zoo, lub sijhawm degradation luv luv, thiab shrinkage tshwm sim hauv lub cev, nrog rau tus nqi shrinkage ntawm 50%. % lossis ntau dua, daim ntawv thov yog txwv. Cov saw saw ntawm L-polylactic acid (PLLA) thiab D-polylactic acid (PDLA) tau teeb tsa tsis tu ncua, thiab lawv cov crystallinity, lub zog kho tshuab thiab melting point yog siab dua li cov ntawm PDLLA.
