I-D-lactic acid iyikhemikhali.Ifomula yamangqamuzana ithi C3H6O3.I-D-lactic acid 90% iyi-high optical (chiral) lactic acid ekhiqizwa ubuchwepheshe be-biological fermentation isebenzisa ama-carbohydrate afana noshukela njengempahla eluhlaza.Umkhiqizo oqediwe we-D-lactic acid uketshezi lwe-viscous olukhanyayo olungenambala noma oluphuzi olukhanyayo olunokunambitheka okumuncu kancane;i-hygroscopic, futhi isixazululo samanzi sibonisa ukusabela kwe-asidi.Ingaxutshwa ngokukhululekile namanzi, i-ethanol noma i-ether, futhi ayincibiliki ku-chloroform.

Isetshenziswa kakhulu ekucubunguleni nasekukhiqizeni izinto ze-polylactic acid kanye nokuhlanganiswa kwezidakamizwa ze-chiral kanye nezibulala-zinambuzane.
Ama-Chiral compounds
Ama-ester e-lactic acid asebenzisa i-D-lactic acid njengezinto zokusetshenziswa asetshenziswa kakhulu ekukhiqizeni amakha, okokwenziwa kwe-resin coating, izinto zokunamathisela noyinki wokunyathelisa, kanye nasekuhlanzeni amapayipi kaphethiloli nezimboni zikagesi.Phakathi kwazo, i-D-methyl lactate ingaxutshwa ngokulinganayo namanzi kanye nezincibilikisi ezihlukahlukene ze-polar, ingahlakaza ngokugcwele i-nitrocellulose, i-cellulose acetate, i-cellulose acetobutyrate, njll kanye nama-polar ahlukahlukene okwenziwa kwe-polar, futhi inephuzu lokuncibilika.Kuyi-solvent enhle kakhulu enephuzu lokubilisa eliphezulu ngenxa yezinzuzo zayo zokushisa okuphezulu kanye nezinga lokuhwamuka elihamba kancane.Ingasetshenziswa njengengxenye ye-solvent exubile ukuze kuthuthukiswe ukusebenza kahle kanye ne-solubilization.Ngaphezu kwalokho, ingasetshenziswa futhi njengempahla eluhlaza yemithi, izibulala-zinambuzane kanye nezandulela zokuhlanganiswa kwamanye ama-chiral compounds., Ophakathi.
izinto eziwohlokayo
I-Lactic acid iyimpahla eluhlaza ye-bioplastic polylactic acid (PLA).Izici ezibonakalayo zezinto ze-PLA zincike ekwakhiweni nasekuqukethweni kwama-isomer ka-D no-L.I-racemate D, L-polylactic acid (PDLLA) ehlanganiswe ku-racemic D, i-L-lactic acid inesakhiwo se-amorphous, futhi izakhiwo zayo zemishini zimbi, isikhathi sokuwohloka sifushane, futhi ukuncipha kwenzeka emzimbeni, ngesilinganiso sokuncipha 50%.% noma ngaphezulu, uhlelo lokusebenza lunomkhawulo.Izingxenye zamaketanga e-L-polylactic acid (PLLA) kanye ne-D-polylactic acid (PDLA) zihlelwa njalo, futhi ubucwebe bazo, amandla emishini nendawo yokuncibilika kuphakeme kakhulu kune-PDLLA.
