Isopropanol
CAS: 67-63-0
ʻO ke kumu hoʻohālike: C3H8O, he waiʻona kalapona ʻekolu. Hoʻomākaukau ʻia e ka ethylene hydration reaction a i ʻole propylene hydration reaction. ʻAʻole waihoʻoluʻu a ʻākala, me ka ʻala ʻala i ka lumi wela. He wahi paila haʻahaʻa kona a me ka nui a hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona a me nā solvents ether. He mea koʻikoʻi koʻikoʻi ia no ka synthesis o nā kemika a hiki ke hoʻohana ʻia e synthesize i nā esters, ethers a me nā waiʻona. He koho maʻamau nō hoʻi ia ma ka ʻoihana e like me ka mea hoʻoheheʻe a me ka mea hoʻomaʻemaʻe, a ma ke ʻano he wahie a i ʻole ka ʻūlū. Loaʻa i ka waiʻona Isopropyl kekahi mea ʻawaʻawa, no laila e noʻonoʻo i nā hana pale i ka wā e hoʻohana ai, e pale i ka pili ʻana me ka ʻili a me ka inhalation.
Ma ka lā 14 o Nowemapa, ua hoʻokiʻekiʻe ʻia ke kumu kūʻai o ka mākeke waiʻona isopropyl i kēia lā ma Shandong, a ʻo ke kumu kūʻai kumu kūʻai ma kahi o 7500-7600 yuan/ton. Ua pau ka hāʻule ʻana o ke kumu kūʻai o ka mākeke acetone i luna a paʻa, e alakaʻi ana i ka hilinaʻi o ka mākeke alkohol isopropyl. Ua hoʻonui ʻia nā nīnau mai nā ʻoihana o lalo, ua makaʻala ke kūʻai aku, a ua piʻi iki ke kikowaena mākeke o ka umekaumaha. Ma keʻano holoʻokoʻa, ʻoi aku ka ikaika o ka mākeke. Manaʻo ʻia e ikaika nui ka mākeke alkohol isopropyl i ka wā pōkole.
Ma ka lā 15 o Nowemapa, ʻo ke kumu kūʻai o ka waiʻona isopropyl i loko o ke kaiāulu ʻoihana he 7660.00 yuan / ton, i emi iho e -5.80% i hoʻohālikelike ʻia me ka hoʻomaka o kēia mahina (8132.00 yuan / ton).
ʻO ke kaʻina hana hana ʻona Isopropyl e pili ana i ka 70% e like me ka lāʻau lapaʻau, pesticides, coatings a me nā ʻāpana ʻē aʻe o nā mea hoʻoheheʻe, he mea koʻikoʻi kemika, nā kumu hana nui he propylene ala a me ke ʻano acetone, ʻoi aku ka mānoanoa o ka loaʻa mua, akā ua kaupalena ka lako home. ʻO ka mea nui i ke ʻano acetone. Aia ia ma ka papa inoa o ka hui 3 carcinogens i ʻike ʻia e ka World Health Organization.
