Hoʻohana o D (+) -LACTIDE me cas13076-17-0

ʻO D-(+)-lactide he mea make cyclic o ka lactic acid, kahi huahana i hana ʻia e nā ʻiʻo ʻiʻo a me nā ʻulaʻula ʻulaʻula i ka wā e wāwahi ai ke kino i nā ʻakika no ka ikehu ma nā pae oxygen haʻahaʻa.
ʻO ka wehewehe ʻana o D (+) -LACTIDE Lactide hiki ke polymerized i ka polylactic acid me ka hoʻohana ʻana i nā catalysts kūpono, e hopena i nā mea me nā waiwai pono.
