Hoʻolauna
ʻO Valeric anhydride kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka valeric anhydride:
ʻAno maikaʻi:
- He wai waihoʻoluʻu ʻole a ʻaʻole ʻo Valeric anhydride me kahi ʻala ʻala.
- Hoʻopili ia me ka wai e hana i ka hui ʻana o ka waika valeric a me ka anhydride valeric.
E hoʻohana:
- Hoʻohana nui ʻia ka Valeric anhydride ma ke ʻano he reagent a me ka waena i ka synthesis organik.
- Hiki ke hoʻohana ʻia e hoʻomākaukau i nā pūhui me nā hui hana like ʻole, e like me ka ethyl acetate, anhydride, a me nā amides.
- Hiki ke hoʻohana ʻia ka Valeric anhydride i ka synthesis o nā pesticides a me nā mea ʻala.
Hanana:
- Hoʻopuka pinepine ʻia ka Valeric anhydride e ka hopena o ka waika valeric me kahi anhydride (e laʻa me ka anhydride acetic).
- Hiki ke hoʻokō ʻia nā kūlana hopena ma ka lumi wela a i ʻole ka wela ma lalo o ka pale o ke kinoea inert.
ʻIke palekana:
- He mea hoʻonāukiuki a ʻino ka Valeric anhydride, e pale aku i ka hoʻopili ʻana me ka ʻili a me nā maka, a e hōʻoia i ka hana ʻana ma kahi wahi i hoʻoluʻu maikaʻi ʻia.
- I ka lawelawe ʻana a me ka mālama ʻana, e pale aku i ka hoʻopili ʻana me nā mea oxidant a i ʻole nā ʻakika ikaika a me nā kumu e pale aku ai i nā hopena pōʻino.
- E hahai i nā protocol mālama pono no nā kemika a hoʻolako iā ʻoe iho me nā mea pale kūpono e like me nā mīkina lima lab, nā aniani palekana, etc.
