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

Indlela yokuhlanganisa ye-DL-lactide isekelwe ku-D, i-L-lactic acid njengempahla eluhlaza, futhi D, L-lactide ihlanganiswa yi-dehydration cyclization phambi kwe-catalyst.Umkhiqizo ongahluziwe wahlanzwa ngokwenziwa kabusha ukuze kulungiswe i-D, L-lactide enesivuno esikhulu nokuhlanzeka okuphezulu.

Ukusetshenziswa kwe-D(+)-LACTIDE nge-cas13076-17-0

I-D-(+)-lactide i-cyclic diester ye-lactic acid, i-byproduct ekhiqizwa amangqamuzana emisipha namangqamuzana egazi abomvu lapho umzimba uphula ama-carbohydrate ukuze uthole amandla emazingeni aphansi oksijini.
Ukucaciswa kwe-D(+)-LACTIDE I-Lactide ingenziwa i-polymerized ibe i-polylactic acid isebenzisa ama-catalysts afanelekile, okuholela ezintweni ezinezici eziwusizo.
