ʻO ka anhydride Butyric/CAS：106-31-0

Hoʻohana

Hoʻohana nui ʻia ka Butyric anhydride ma ke ʻano he reagent acylating i ka synthesis organik. Hiki iā ia ke hana me nā alcohols, phenols, amines, a me nā mea ʻē aʻe e hana i nā esters like, phenyl ethers, amides a me nā hui ʻē aʻe. Hiki ke hoʻohana ʻia ka Butyric anhydride ma ke ʻano he mea maka no nā uhi, nā kala a me nā plastics. Hiki ke hoʻomākaukau ʻia ka Butyric anhydride ma ka hana ʻana i ka waikawa butyric me ka acetic anhydride. Hoʻokō pinepine ʻia nā kūlana hana ma lalo o nā kūlana acidic a ma nā mahana haʻahaʻa. He mea hoʻonāukiuki a ʻānai ka Butyric anhydride a hiki ke hoʻonāukiuki i nā maka, ka ʻili, ke ala hanu a me ka ʻōnaehana digestive. I ka wā o ka hana, pono e mālama pono e pale aku i ka pili ʻana me ka ʻili a me nā maka, a e hōʻoia i ka hana ʻana ma lalo o nā kūlana ea maikaʻi.

He wai ʻole kala a moakaka hoʻi ia me kahi ʻala ʻoluʻolu ʻole. ʻO ka nui o ka nui he 0.9668 (20/20 ℃), ʻo ke kiko heheʻe he -75 ℃, a ʻo ke kiko paila he 198 ℃. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ether. Hoʻoheheʻe ʻia i loko o ka waikawa butyric ke hālāwai me ka wai. Hoʻopili ia me nā alcohols e hana i nā esters. He wai ʻole kala, moakaka a hiki ke lapalapa. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hoʻoheheʻe ʻia e hana i ka waikawa butyric, a hiki ke hoʻoheheʻe ʻia i loko o ka ether.

ʻŌpala a me ka Hoʻouna ʻana

195 kg/pahu a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa

Mālama a me ka mālama ʻana

Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
