DL-Lactidehoʻomohala wale ʻia a hana ʻia, ma hope o ʻekolu hoʻomaʻemaʻe, kiʻekiʻe maʻemaʻe, kiʻekiʻe kiʻekiʻe, a me ke kumu kūʻai maikaʻi loa.
ʻO ka hale hana nui wale nō ma Kina.Paʻa ka maikaʻi a haʻahaʻa ke kumukūʻai.
LactideʻO ka flake ʻaʻohe kala a i ʻole ke aniani nila, ʻo ka helu heheʻe he 93-95 ℃, hiki ke hoʻoheheʻe ʻia i ka chloroform, ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.Maʻalahi e hydrolyze a polymerize.Lactidehiki ke hoʻohana ʻia e like me ka hana ʻana i ka waika polylactic kiʻekiʻe, cyclic esterification agent.

DL-Lactidehoʻohana ʻia e hana i ka 2-hydroxy-propionic acid 1-(1-phenyl-ethoxycarbonyl)-ethyl ester.Hana ia ma ke ʻano he kumu waiwai koʻikoʻi a me ka waena waena i hoʻohana ʻia i ka synthesis organik, nā lāʻau lapaʻau, agrochemical a me nā dyes.Hoʻopili ʻia ia i ka alcoholysis enzymatic e hana i nā alkyl (R) -lactates a me alkyl (S,S) -lactyllactates.
DL-LactideHoʻohana pinepine ʻia ʻo ia ma ke ʻano he pale pale i nā uhi ʻeha, a i ʻole nā heleuma, nā ʻili a i ʻole nāʻuo i ka ʻoki ʻana, no ka mea, hoʻohaʻahaʻa ʻia i loko o ʻeono mahina i ka waika lactic innocuous.
Inā makemake ʻoe, mai haʻalele ʻoe, e hoʻokipa mai iā mākou, e hoʻouna mākou iā ʻoe i ke kumukūʻai maikaʻi loa ma hope koke o ka loaʻa ʻana o kāu nīnau.
