ʻO ka D-lactic acid he mea kemika. ʻO ke kumu molekala C3H6O3. ʻO ka D-lactic acid 90% he kiʻekiʻe optical (chiral) lactic acid i hana ʻia e ka ʻenehana fermentation biological me ka hoʻohana ʻana i nā ʻakika e like me ke kō e like me nā mea maka. ʻO ka huahana i hoʻopau ʻia o ka D-lactic acid he wai liʻiliʻi ʻeleʻele a i ʻole melemele māmā me kahi ʻono ʻawaʻawa; he hygroscopic, a ua hōʻike ka hoʻonā wai i ka hopena ʻakika. Hiki ke hoʻohui wale ʻia me ka wai, ethanol a i ʻole etera, a hiki ʻole ke hoʻoheheʻe ʻia i loko o ka chloroform.

Hoʻohana nui ʻia ia i ka hana ʻana a me ka hana ʻana i nā mea polylactic acid a me ka synthesis o nā lāʻau chiral a me nā intermediates pesticide.
Huihui kiral
Lactic acid esters e hoʻohana ana i ka D-lactic acid e like me nā mea maka i hoʻohana nui ʻia i ka hana ʻana i nā mea ʻala, nā synthetic resin coatings, adhesives a me nā inika paʻi, a me ka hoʻomaʻemaʻe ʻana i nā pipeline petroleum a me nā ʻoihana uila. I waena o lākou, hiki ke hui like ʻia ka D-methyl lactate me ka wai a me nā mea hoʻoheheʻe polar like ʻole, hiki ke hoʻopau piha i ka nitrocellulose, cellulose acetate, cellulose acetobutyrate, etc. He mea hoʻoheheʻe maikaʻi loa me ka helu hoʻolapalapa kiʻekiʻe ma muli o kāna mau mea maikaʻi o ka wela kiʻekiʻe a me ka wikiwiki evaporation lohi. Hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana o ka solvent hui e hoʻomaikaʻi i ka hana a me ka solubilization. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā lāʻau lapaʻau, pesticides a me nā precursors no ka synthesis o nā pūhui chiral ʻē aʻe. , Kūwaena.
mea degradable
ʻO ka waikawa lactic ka mea maka no ka bioplastic polylactic acid (PLA). ʻO nā waiwai kino o nā mea PLA e pili ana i ka haku mele a me ka ʻike o D a me L isomers. ʻO ka racemate D, L-polylactic acid (PDLLA) synthesized mai racemic D, L-lactic acid he ʻano amorphous, a ʻilihune kona mau ʻano mechanical, pōkole ka manawa hoʻohaʻahaʻa, a hiki ke emi i loko o ke kino, me ka wikiwiki o ka emi ʻana. 50%. % a ʻoi aku paha, ua kaupalena ʻia ka noi. Hoʻonohonoho mau ʻia nā ʻāpana kaulahao o L-polylactic acid (PLLA) a me D-polylactic acid (PDLA), a ʻoi aku ka kiʻekiʻe o ko lākou crystallinity, mechanical strength and melting point ma mua o ka PDLLA.
