(r) -lactate ine cas 10326-41-7
D-lactic acid ikemikari. Iyo molecular formula ndeye C3H6O3. D-lactic acid 90% is high optical (chiral) lactic acid inogadzirwa nebiological fermentation tekinoroji ichishandisa makabhohaidhiretsi akafanana neshuga semidziyo. Chigadzirwa chakapedzwa cheD-lactic acid imvura isina ruvara kana yakajeka yero yakajeka viscous liquid ine zvishoma kuvava kuravira; iri hygroscopic, uye mhinduro ine aqueous inoratidza acidic reaction. Inogona kusanganiswa zvakasununguka nemvura, ethanol kana ether, uye haina kunyungudika muchloroform.

Inonyanya kushandiswa mukugadzirisa nekugadzira zvinhu zvepolylactic acid uye kugadzirwa kwemishonga yechiral uye mishonga yezvipembenene.
Chiral compounds
Lactic acid esters inoshandisa D-lactic acid semidziyo inoshandiswa zvakanyanya mukugadzirwa kwezvinonhuhwirira, synthetic resin coatings, zvinonamira neingi dzekudhinda, uye zvakare mukuchenesa mapaipi epetroleum uye maindasitiri emagetsi. Pakati pavo, D-methyl lactate inogona kusanganiswa zvakaenzana nemvura uye zvakasiyana-siyana zvinonyungudutsa polar, inogona kunyungudutsa zvakakwana nitrocellulose, cellulose acetate, cellulose acetobutyrate, nezvimwewo uye zvakasiyana-siyana polar synthetic polymers, uye ine nzvimbo yekunyunguduka. Iyo yakanakisa solvent ine yakakwira yekubikira poindi nekuda kwemabhenefiti ayo ekushisa kwakanyanya uye inononoka evaporation rate. Inogona kushandiswa sechikamu chemusanganiswa solvent kuvandudza kushanda uye solubilization. Pamusoro pezvo, inogona zvakare kushandiswa seyakabikwa yemishonga, mishonga yezvipembenene uye precursors ye synthesis yemamwe chiral makomisheni. , Pakati.
zvinhu zvinoshatisa
Lactic acid ndiyo mbishi yezvinhu zvebioplastic polylactic acid (PLA). Hunhu hwemuviri hwezvinhu zvePLA zvinoenderana nekuumbwa uye zvirimo zveD uye L isomers. Iyo racemate D, L-polylactic acid (PDLLA) yakagadzirwa kubva ku racemic D, L-lactic acid ine amorphous chimiro, uye maitiro ayo emagetsi akashata, nguva yekuora ipfupi, uye kuderera kunoitika mumuviri, nekuderera kwe 50%. % kana kupfuura, iyo application ishoma. Zvikamu zveketani zveL-polylactic acid (PLLA) uye D-polylactic acid (PDLA) zvinogara zvakarongwa, uye crystallinity yavo, simba remagetsi uye nzvimbo yekunyunguduka zvakakwirira kudarika izvo zvePDLLA.
