Methacrylamide
waiwai kemika
Ke ʻano kemika: C4H7NO Kaumaha molekala: 85.1 CAS: 79-39-0 EINECS: 201-202-3 Kiko heheʻe: 108 ℃ Kiko paila: 215 ℃
Hoʻolauna huahana a me nā hiʻohiʻona
ʻO Methacrylamide kahi hui organik me ke ʻano molekala C4H7NO. ʻIke ʻia hoʻi ʻo 2-methylacrylamide (2-methyl-propenamide), 2-methyl-2-propenamide (2-propenAMID), α-propenamide (α-methylpropenamide), Alpha-methyl acrylic amide). Ma ka mahana o ka lumi, he kristal keʻokeʻo ka methylacrylamide, he melemele iki nā huahana ʻoihana. Maʻalahi ka hoʻoheheʻe ʻia i ka wai, hoʻoheheʻe ʻia i ka waiʻona, methylene chloride, hoʻoheheʻe iki ʻia i ka ether, chloroform, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka petroleum ether, carbon tetrachloride. Ma ke ana wela kiʻekiʻe, hiki i ka methylacrylamide ke polymerize a hoʻokuʻu i ka nui o ka wela, kahi mea maʻalahi ke kumu o ka haki ʻana o ka moku a me ka pahū ʻana. I ke ahi ākea, hiki ke hoʻoheheʻe ʻia ka methylacrylamide wela kiʻekiʻe, ka hoʻokuʻu ʻana i ka carbon monoxide ʻawahia, carbon dioxide, nitrogen oxide a me nā kinoea nitrogen oxide ʻē aʻe. He kemika ʻawahia kēia huahana. Hiki iā ia ke hoʻonāukiuki i nā maka, ka ʻili a me ka membrane mucous. Pono e sila ʻia a mālama ʻia mai ka mālamalama. ʻO Methylacrylamide kahi waena i ka hana ʻana o ka methyl methacrylate.
hoʻohana
Hoʻohana nui ʻia ia i ka hoʻomākaukau ʻana o ka methyl methacrylate, organic synthesis, polymer synthesis a me nā kahua ʻē aʻe. Eia kekahi, methylacrylamide a i ʻole silika degumming, dyeing ma mua o ka hoʻololi ʻana i ke kaumaha.
pūʻolo a me ka halihali
B. Hiki ke hoʻohana ʻia kēia huahana, 25KG, ʻeke.
C. E mālama pono i kahi i hoʻopaʻa ʻia ma kahi anu, maloʻo a me ka ea i loko. Pono e hoʻopaʻa pono ʻia nā ipu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa pono ʻia kēia huahana i ka wā o ka lawe ʻana e pale aku i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui pū ʻana.
