D-lactic acid ikemikari. Fomura yemamorekuru ndeye C3H6O3. D-lactic acid 90% ilactic acid ine optical (chiral) yakawanda inogadzirwa ne biological fermentation technology ichishandisa makabhohaidhiretsi akafanana neshuga sezvinhu zvakabikwa. Chigadzirwa chakapedzwa cheD-lactic acidimvura isina ruvara kana yero yakajeka, yakajeka uye ine kuravira kushoma; haina kunaka, uye mvura ine acidic. Inogona kusanganiswa nemvura, ethanol kana ether, uye hainyungudike mu chloroform.

Inonyanya kushandiswa mukugadzira nekugadzira zvinhu zve polylactic acid uye mukugadzirwa kwemishonga ye chiral nemishonga yezvipembenene.
Mishonga yeChiral
Maester eLactic acid anoshandisa D-lactic acid sezvinhu zvakabikwa anoshandiswa zvakanyanya mukugadzira zvinonhuhwirira, machira ekugadzira resin, maglues neinki dzekudhinda, pamwe nekuchenesa mapaipi epetroleum nemaindasitiri emagetsi. Pakati pawo, D-methyl lactate inogona kusanganiswa zvakaenzana nemvura uye zvakasiyana-siyana zvinonyungudutsa polar, inogona kunyungudutsa zvizere nitrocellulose, cellulose acetate, cellulose acetobutyrate, nezvimwewo uye mapolymer akasiyana-siyana epolar synthetic, uye ine poindi yekunyunguduka. Isolvent yakanaka kwazvo ine poindi yekufashaira yakawanda nekuda kwezvakanaka zvayo zvekupisa kwakanyanya uye mwero wekubuda kwemvura zvishoma nezvishoma. Inogona kushandiswa sechikamu che mixed solvent kuti ivandudze kushanda uye kunyunguduka. Pamusoro pezvo, inogona zvakare kushandiswa sezvinhu zvakabikwa zvemishonga, mishonga yezvipembenene uye zvinotangira kugadzirwa kwemamwe ma chiral compounds. , Intermediate.
zvinhu zvinoora
Asidhi yeLactic ndiyo chinhu chakakosha chebioplastic polylactic acid (PLA). Hunhu hwezvinhu zvePLA hunoenderana nekuumbwa uye zviri mukati meD neL isomers. Iyo racemate D, L-polylactic acid (PDLLA) yakagadzirwa kubva ku racemic D, L-lactic acid ine chimiro chisina kuumbwa, uye hunhu hwayo hwemakanika hauna kunaka, nguva yekuora ipfupi, uye shrinkage inoitika mumuviri, ne shrinkage rate ye50% % kana kupfuura, kushandiswa kwayo kwakaganhurirwa. Zvikamu zvecheni zveL-polylactic acid (PLLA) neD-polylactic acid (PDLA) zvinorongwa nguva dzose, uye crystallinity yavo, simba remakanika uye melting point zvakakwirira kupfuura zvePDLLA.
