DL-Lactideimapangidwa ndi kupangidwa kokha, pambuyo pa kuyeretsedwa katatu, chiyero chapamwamba, khalidwe lapamwamba, ndi mtengo wabwino kwambiri.
Fakitale yokhayo yopangidwa mochuluka ku China.Ubwino umatsimikizika ndipo mtengo wake ndi wotsika.
Lactidendi flake yopanda mtundu yowoneka bwino kapena kristalo wa singano, malo osungunuka ndi 93-95 ℃, amasungunuka mosavuta mu chloroform, ethanol, osasungunuka m'madzi.Zosavuta hydrolyze ndi polymerize.Lactideangagwiritsidwe ntchito monga kupanga mankhwala mkulu polylactic asidi, cyclic esterification wothandizira.

Za Ntchito yaDL-Lactide
DL-Lactideamagwiritsidwa ntchito popanga 2-hydroxy-propionic acid 1-(1-phenyl-ethoxycarbonyl) -ethyl ester.Imakhala ngati zopangira zofunikira komanso zapakatikati zomwe zimagwiritsidwa ntchito popanga organic synthesis, mankhwala, agrochemicals ndi utoto.Imakhudzidwa ndi enzymatic alcoholysis kupanga alkyl (R) -lactates ndi alkyl (S,S) -lactyllactates.
DL-LactideNthawi zambiri amagwiritsidwa ntchito ngati chotchinga chotchinga pamabala, kapena ngati anangula, zomangira kapena mauna pakuchita opaleshoni, chifukwa amawonongeka pakadutsa miyezi isanu ndi umodzi kukhala lactic acid wopanda vuto.
Ngati mukuzifuna, chonde musaphonye, kulandiridwa kuti mutilankhule, tidzakutumizirani mtengo wabwino kwambiri mukangofunsa.
