ʻIsopropanol

ʻIsopropanol
CAS: 67-63-0
ʻO ke ʻano kemika: C3H8O, he waiʻona ʻekolu-kalapona. Hoʻomākaukau ʻia ia ma o ka hopena hydration ethylene a i ʻole ka hopena hydration propylene. ʻAʻohe kala a moakaka, me ka ʻala ʻawaʻawa ma ka mahana o ka lumi. He haʻahaʻa kona wahi paila a me ka nui a maʻalahi hoʻi e hoʻoheheʻe ʻia i ka wai, ka waiʻona a me nā mea hoʻoheheʻe ether. He mea koʻikoʻi ia no ka synthesis o nā kemika a hiki ke hoʻohana ʻia e synthesize i nā esters, ethers a me nā alcohols. He koho maʻamau nō hoʻi ia i ka ʻoihana ma ke ʻano he mea hoʻoheheʻe a me ka mea hoʻomaʻemaʻe, a ma ke ʻano he wahie a mea hoʻoheheʻe paha. Loaʻa i ka waiʻona Isopropyl kekahi ʻawaʻawa, no laila e hoʻolohe i nā hana pale i ka wā e hoʻohana ai, e pale i ka pili ʻana me ka ʻili a me ka hanu ʻana.

Ma Nowemapa 14, ua hoʻokiʻekiʻe ʻia ke kumukūʻai mākeke waiʻona isopropyl i kēia lā ma Shandong, a ʻo ke kumukūʻai kuhikuhi mākeke ma kahi o 7500-7600 yuan/ton. Ua oki ka hāʻule ʻana o ke kumukūʻai mākeke acetone ma uka a ua paʻa, e hoʻokele ana i ka hilinaʻi o ka mākeke waiʻona isopropyl. Ua piʻi aʻe nā nīnau mai nā ʻoihana ma lalo, ua akahele ke kūʻai ʻana, a ua piʻi iki ke kikowaena o ka mākeke. Ma keʻano holoʻokoʻa, ua ʻoi aku ka ikaika o ka mākeke. Manaʻo ʻia e ikaika nui ka mākeke waiʻona isopropyl i ka wā pōkole.

Ma Nowemapa 15, ʻo ke kumukūʻai maʻamau o ka waiʻona isopropyl i loko o ke kaiāulu ʻoihana he 7660.00 yuan/ton, i emi iho ma -5.80% i hoʻohālikelike ʻia me ka hoʻomaka ʻana o kēia mahina (8132.00 yuan/ton).

ʻO ke kaʻina hana hana ʻana o ka waiʻona Isopropyl ma kahi o 70% e like me nā lāʻau lapaʻau, nā pesticides, nā uhi a me nā ʻano mea hoʻoheheʻe ʻē aʻe, he mea nui ia o nā mea maka kemika, ʻo nā ʻano hana hana nui he ʻano propylene a me ke ʻano acetone, ʻoi aku ka mānoanoa o ka waiwai mua, akā ua kaupalena ʻia ka lako kūloko, ʻo ia hoʻi ke ʻano acetone. Aia ia ma ka papa inoa o nā carcinogens Group 3 i ʻike ʻia e ka World Health Organization.
