I-DL-Lactideithuthukiswa kuphela futhi ikhiqizwa, ngemuva kokuhlanzwa okuthathu, ubumsulwa obuphezulu, ikhwalithi ephezulu, kanye nentengo engcono kakhulu.
Okuwukuphela kwemboni ekhiqizwe ngobuningi e-China. Ikhwalithi iqinisekisiwe futhi intengo iphansi.
I-Lactidei-flake esobala engenambala noma ikristalu yenaliti, indawo encibilikayo ingu-93-95 ℃, inyibilika kalula ku-chloroform, i-ethanol, ayincibiliki emanzini. Kulula ukwenza i-hydrolyze futhi i-polymerize.I-Lactideingasetshenziswa njengokukhiqizwa kwe-polylactic acid yezokwelapha ephezulu, i-ejenti ye-cyclic esterification.

Okokusebenza kweI-DL-Lactide
I-DL-Lactideisetshenziselwa ukukhiqiza i-2-hydroxy-propionic acid 1-(1-phenyl-ethoxycarbonyl)-ethyl ester. Isebenza njengempahla eluhlaza ebalulekile kanye nendawo ephakathi esetshenziswa ku-organic synthesis, imithi, amakhemikhali ezolimo kanye nodayi. Ibandakanyeka ku-enzymatic alcoholysis ukukhiqiza kokubili i-alkyl (R) -lactates kanye ne-alkyl (S,S) -lactyllactates.
I-DL-Lactideivame ukusetshenziswa njengongqimba oluyisivikelo ezimbotsheni zamanxeba, noma njengamahange, izikulufu noma amanetha ekuhlinzeni, njengoba incipha cishe ezinyangeni eziyisithupha ibe i-lactic acid engenangozi.
Uma uyidinga, sicela ungaphuthelwa, wamukelekile ukuxhumana nathi, sizokuthumela intengo engcono kakhulu ngemuva kokuthola uphenyo lwakho.
