Hoʻolauna
ʻO α-propyl-γ-butyrolactone (ʻike pū ʻia ʻo α-MBC) he mea hoʻoheheʻe kūlohelohe maʻamau. Loaʻa iā ia kahi wai wai kala ʻole a ʻala ʻole a he haʻahaʻa haʻahaʻa o ka evaporation ma ka lumi wela. Eia nā kikoʻī e pili ana i ka α-propyl-γ-butyrolactone:
ʻAno maikaʻi:
- α-propyl-γ-butyrolactone he solubility maikaʻi loa a hiki ke hoʻoheheʻe i nā mea olaola he nui e like me nā resins, nā pena a me nā uhi.
- ʻAʻole hiki ke puhi ʻia kēia lactone, akā hiki ke hana i nā kinoea ʻawaʻawa i nā wela kiʻekiʻe.
E hoʻohana:
- Hoʻohana nui ʻia ka α-Propyl-γ-butyrolactone i nā kaʻina hana ʻenehana no nā mea hoʻoheheʻe, ʻāhuʻu, pena, nā uhi, adhesives, a me nā huahana plastik.
Hanana:
- ʻO ka α-propyl-γ-butyrolactone ka mea maʻamau i hoʻomākaukau ʻia e ka esterification o ka γ-butyrolactone. Ma kēia kaʻina hana, hoʻopili ʻia ka γ-butyrolactone me ka acetone a hoʻohui ʻia ka nui o ka waika hydrochloric a i ʻole sulfuric acid ma ke ʻano he catalyst.
ʻIke palekana:
- I ka lawelawe ʻana i ka α-propyl-γ-butyrolactone, e pale i ka pili lōʻihi ʻana me ka ʻili a me ka inhalation o nā kinoea.
- Pono e mālama ʻia nā ʻano palekana a me nā hoʻoponopono i ka wā e mālama ai a mālama i ka α-propyl-γ-butyrolactone.
