Dl-lactideimapangidwa pang'onopang'ono ndikupangidwa, pambuyo pa mapiritsi atatu, chiyero chachikulu, chamtengo wapatali, komanso mtengo wabwino kwambiri.
Fakitale yopangidwa ndi miyeso ku China. Khalidwe limatsimikizika ndipo mtengo wake ndi wotsika.
LoziraNdiwopanda maonekedwe opanda utoto kapena singano yosungunuka ndi 93-95 ℃, kusungunuka mosavuta mu chloroform, ethanol, kapena influble m'madzi. Zosavuta hydrolyze ndi polymer.LoziraItha kugwiritsidwa ntchito ngati kupanga kwa polylactic acid ambiri, wothandizira cyclic.

Kugwiritsa ntchitoDl-lactide
Dl-lactideimagwiritsidwa ntchito kupanga 2-hydroxy-prilonic acid 1- (1-phenyl-ethoxycanyl) - ester. Imagwira ngati chinthu chofunikira kwambiri komanso chapakati chomwe chimagwiritsidwa ntchito pazinthu zachilengedwe zopangidwa ndi mankhwala, abulaceuticals, abulamumini ndi utoto. Amakhala mu enzymatic molcohoalys kuti apange onse a alkyl (r) -Lactates ndi ma alkyl (s, s) - 2.
Dl-lactideNthawi zambiri imagwiritsidwa ntchito ngati chotetezera chotchinga cha bala, kapena ngati chimanga, zomangira kapena mauna opaleshoni, chifukwa zimasokoneza pafupifupi miyezi isanu ndi umodzi kupita ku lactic ya Lactic.
Ngati mukufuna, chonde musaphonye izi, talandiridwa kuti mudzatipeze, tikutumizirani mtengo wabwino mutafunsana.
