Hoʻohana huahana:
Hoʻohana nui ʻia ka n-Butyric anhydride ma ke ʻano he acylation reagent i ka synthesis organik.Hiki iā ia ke hana me nā waiʻona, nā phenols, nā amines, a me nā mea ʻē aʻe e hana i nā esters like, phenolic ethers, amides a me nā mea ʻē aʻe.Hiki ke hoʻohana ʻia ka anhydride butyric ma ke ʻano he mea maka no nā pena, nā mea pena a me nā plastics.
ʻIke palekana:
1.n-ʻO ka Butyric anhydride he mea hoʻonāukiuki a hoʻomāinoino a hiki ke hoʻonāukiuki i ka maka, ka ʻili, ka ʻōpū hanu a me ka ʻōnaehana digestive.
2. Pono e mālama i ka hoʻopili ʻana me ka ʻili a me nā maka a e hōʻoia i ka hana ʻana o ka hana ma lalo o nā kūlana ventilated maikaʻi.
3. Inā pili ʻole me ka butyric anhydride, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.
4. I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā mea oxidizing a me nā combustibles.
