Yintoni i-D(+)-LACTIDE nge-cas13076-17-0?

Indlela yokudibanisa ye-DL-lactide isekelwe kwi-D, i-L-lactic acid njengento eluhlaza, kunye ne-D, i-L-lactide idityaniswe yi-cyclization ye-dehydration phambi kwe-catalyst. Imveliso ekrwada yahlanjululwa ngokulungiswa kwakhona ukuze kulungiswe i-D, L-lactide enesivuno esikhulu kunye nokucoceka okuphezulu.

Ukusetyenziswa kwe-D (+)-LACTIDE kunye ne-cas13076-17-0

I-D-(+)-lactide yi-cyclic diester ye-lactic acid, i-byproduct eveliswa ngamaseli emisipha kunye neeseli ezibomvu zegazi xa umzimba uqhekeza i-carbohydrates yamandla kumanqanaba aphantsi oksijini.
Ukucaciswa kwe-D (+) -LACTIDE I-Lactide inokuthi ifakwe i-polymerized kwi-polylactic acid isebenzisa i-catalysts efanelekileyo, okubangelwa izinto eziluncedo.
