Iyini i-DL-Lactide CAS 95-96-5?

I-Lactide iyi-flake ebonisa ngale engenambala noma ikristalu e-acicular, indawo encibilikayo engu-93-95℃, encibilika ku-chloroform, i-ethanol, engancibiliki emanzini. I-hydrolysis elula, i-polymerization elula. Ingasetshenziselwa ukukhiqiza i-polylactic acid yezokwelapha kanye ne-ejenti ye-cycloesterification.

Isicelo

Ukukhiqizwa kwe-lactide kusuka ku-lactic acid impahla eluhlaza kusekelwe ikakhulukazi ekusetshenzisweni kwe-lactic acid condensation ukukhiqiza ama-oligomers e-lactic acid, bese ama-oligomers e-lactic acid akhishwa upolymer futhi ahanjiswe ngamabhayisikili ukuze akhiqize i-lactide. Yonke inqubo idinga ukwenziwa ngaphansi kwezimo zokushisa okuphezulu, ukucindezela okungalungile kanye ne-catalysis. Phakathi nenqubo, ukuze kuthuthukiswe isivuno sonke, okungaphenduliyo kufanele kusetshenziswe kabusha yi-reflux. Okokugcina, imikhiqizo ye-lactide efanelekayo ingatholakala ngezindlela ezithile zokuhlanza.
Njengempahla ebolayo, isetshenziselwa kakhulu ukulungisa amapuleti, izinsimbi zokuhlinza, ama-stents enhliziyo, nezigcwalisi zomzimba.
