Hoʻolauna
ʻO δ-Octanolactone, i kapa ʻia ʻo caprolactone, he mea hoʻohuihui. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me kahi ʻala ʻano o ka octanol. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o δ-octanololide:
ʻAno maikaʻi:
- ʻO ka δ-Octanolactone he wai hoʻoheheʻe i hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik he nui.
- He pūhui paʻa ʻole ia e hiki ke hoʻopili i ka polymerization a me ka hydrolysis.
- He haʻahaʻa viscosity, haʻahaʻa haʻahaʻa haʻahaʻa a me ka wetability maikaʻi.
E hoʻohana:
- Hoʻohana ʻia ʻo δ-Octanolactone i kahi ākea o nā noi, me ka hana ʻana i nā plastics, polymer synthesis, a me nā uhi uhi.
- Hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana o nā solvents, catalysts a me nā plasticizers.
- Ma ke kahua o nā polymers, hiki ke hoʻohana ʻia ka δ-octanol lactone e hoʻomākaukau i ka polycaprolactone (PCL) a me nā polymers ʻē aʻe.
- Hiki ke hoʻohana ʻia i nā lāʻau lapaʻau, nā uhi, nā adhesives, nā mea encapsulation, etc.
Hanana:
- Hiki ke hoʻomākaukau ʻia ka δ-Octololide e ka esterification o ε-caprolactone.
- Hoʻokō pinepine ʻia ka hopena ma lalo o nā kūlana hoʻololi kūpono ma o ka hoʻopili ʻana i ka ε-caprolactone me kahi catalyst waika e like me ka methanesulfonic acid.
- Pono ke kaʻina hana hoʻomākaukau i ka mana o ka wela o ka hopena a me ka manawa e loaʻa ai kahi huahana maʻemaʻe kiʻekiʻe.
ʻIke palekana:
- Hiki ke hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōpū hanu a pono e pale ʻia ke hoʻopā ʻia.
- I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono ia e mālama i kahi ʻano maikaʻi-ventilated a pale i nā kumu ahi a me nā wela kiʻekiʻe.
- I ka wā e hoʻolei ai i ka ʻōpala, pono e mālama ʻia a hoʻolei ʻia e like me nā lula kūloko.
