Ohun elo

Isejade ti lactic acid lati inu ohun elo aise ti lactic acid jẹ ipilẹ akọkọ lori lilo isunmọ lactic acid lati ṣe agbejade awọn oligomers lactic acid, ati lẹhinna awọn oligomers lactic acid ti wa ni depolymerized ati cyclized lati gbejade lactide. Gbogbo ilana nilo lati ṣe labẹ awọn ipo ti iwọn otutu giga, titẹ odi ati catalysis. Lakoko ilana naa, lati le mu ikore gbogbogbo pọ si, aibikita yẹ ki o tun lo nipasẹ reflux. Lakotan, awọn ọja lactide ti o peye le ṣee gba nipasẹ awọn ọna isọdọmọ kan.
Gẹgẹbi ohun elo biodegradable, o jẹ lilo ni pataki fun titọ awọn awo, awọn sutures iṣẹ abẹ, awọn stents ọkan, ati awọn ohun elo ara.
