He aha ka DL-Lactide CAS 95-96-5?

ʻO ka Lactide he flake māmā ʻole a i ʻole ke aniani acicular, wahi hoʻoheheʻe 93-95 ℃, hiki ke hoʻoheheʻe ʻia i ka chloroform, ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka wai. Hydrolysis maʻalahi, polymerization maʻalahi. Hiki ke hoʻohana ʻia e hana i ka polylactic acid a me ka cycloesterification agent.

Hoʻokumu ʻia ka hana ʻana o ka lactide mai ka lactic acid raw material ma ka hoʻohana ʻana i ka condensation lactic acid e hana ai i nā oligomers lactic acid, a laila hoʻopau ʻia nā oligomers lactic acid a cyclized e hana i ka lactide. Pono e hoʻokō ʻia ke kaʻina holoʻokoʻa ma lalo o nā kūlana o ka wela kiʻekiʻe, ke kaomi ʻino a me ka catalysis. I ka wā o ke kaʻina hana, i mea e hoʻomaikaʻi ai i ka hopena holoʻokoʻa, pono e hoʻohana hou ʻia ka unreactant e ka reflux. ʻO ka mea hope loa, hiki ke loaʻa nā huahana lactide kūpono ma o kekahi mau mea hoʻomaʻemaʻe.
Ma ke ʻano he mea biodegradable, hoʻohana nui ʻia no ka hoʻoponopono ʻana i nā papa, nā sutures surgical, stents heart, a me nā hoʻopiha kino.
