Kodi DL-Lactide CAS 95-96-5 ndi chiyani?

Lactide ndi flake yopanda mtundu yowonekera kapena kristalo wa acicular, malo osungunuka 93-95 ℃, osungunuka mu chloroform, ethanol, osasungunuka m'madzi. Easy hydrolysis, polymerization yosavuta. Itha kugwiritsidwa ntchito kupanga mankhwala a polylactic acid ndi cycloesterification wothandizira.

Kugwiritsa ntchito

Kupanga kwa lactide kuchokera ku lactic acid yaiwisi kumachokera makamaka pakugwiritsa ntchito lactic acid condensation kupanga lactic acid oligomers, ndiyeno lactic acid oligomers ndi depolymerized ndi cyclized kupanga lactide. Njira yonseyi iyenera kuchitidwa pansi pa kutentha kwakukulu, kupanikizika koipa ndi catalysis. Panthawiyi, kuti apititse patsogolo zokolola zonse, wosayanjanitsika ayenera kugwiritsidwanso ntchito ndi reflux. Pomaliza, mankhwala oyenerera a lactide amatha kupezeka kudzera mu njira zina zoyeretsera.
Monga chinthu chosawonongeka, chimagwiritsidwa ntchito kwambiri kukonza mbale, ma sutures opangira opaleshoni, ma stents amtima, ndi zodzaza thupi.
