(r) -lactate nge-CAS 10326-41-7
(R)-Lactate CAS 10326-41-7 ikhemikhali. Ifomula yamangqamuzana ithi C3H6O3. (R)-Lactate 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
I-Lactic acid esters isebenzisa (R) -Lactate njengezinto zokusetshenziswa isetshenziswa kakhulu ekukhiqizeni amakha, okokwenziwa kweresin enamathelayo, izinto zokunamathisela noyinki wokuphrinta, kanye nasekuhlanzeni amapayipi e-petroleum 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 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) eyenziwe ku-racemic D, i-L-lactic acid inesakhiwo se-amorphous, futhi izakhiwo zayo zemishini zimbi, isikhathi sokuwohloka sifushane, futhi ukushwabana kwenzeka emzimbeni, ngesilinganiso sokushwabana esingu-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.
