Hōʻike huahana:
ʻO ka Methanol, ka mea i kapa ʻia ʻo hydroxymethane, he pūhui kūlohelohe a me ka waiʻona mono saturated maʻalahi loa i loko o ka hale. ʻO CH3OH/CH₄O kona ʻano kemika, ʻo ia ka CH₃OH ke ʻano pōkole, hiki ke hōʻike i ka hui hydroxyl o ka methano. No ka mea, ua loaʻa mua i loko o ka distillation maloʻo o ka lāʻau, ua ike no hoi ia & ldquo; lāʻau waiʻona & rdquo; aiʻole & ldquo; uhane laau & rdquo;. ʻO ka haʻahaʻa haʻahaʻa loa o ka lāʻau make o ke kanaka ma kahi o 100mg / kg ke kaumaha o ke kino, hiki ke make ka waha o 0.3 ~ 1g / kg. Hoʻohana ʻia i ka hana ʻana i ka formaldehyde a me nā pesticides, a me nā mea ʻē aʻe, a hoʻohana ʻia ma ke ʻano he extractant o nā mea organik a me ka denaturant waiʻona, a me nā mea ʻē aʻe.
Nā Waiwai a me ka Paʻa:
Hiki ke hana i ka wai akaka ʻole, kona mahu a me ka ea i nā hui pahū, ke puhi ʻia e hana i ka lapalapa uliuli. ʻO ka mahana koʻikoʻi 240.0°C; ʻO ke kaomi koʻikoʻi 78.5atm, hiki ke hui pū me ka wai, ethanol, etera, benzene, ketones a me nā mea hoʻoheheʻe ʻē aʻe. Hoʻokumu ʻia kona mahu i hui pū ʻia me ka ea, hiki ke hoʻohūhū a pahū ke ʻike ʻia i ke ahi a me ka wela nui. Hiki ke hana ikaika me ka oxidant. Inā hālāwai ia me ka wela nui, piʻi ke kaomi i loko o ka pahu, a aia ka pōʻino o ka pohā a me ka pahū. ʻAʻohe lapalapa māmā i ke ahi. Hiki ke hōʻiliʻili i ka uila static a hoʻā i kona mahu.
Hoʻohana huahana:
1. ʻO kekahi o nā mea waiwai kumu, hoʻohanaʻia i ka hanaʻana i ka chloromethane, methylamine a me dimethyl sulphate a me nā mea'ē aʻe he nui. He mea maka no ka pesticides (insecticides, acaricides), nā lāʻau (sulfonamides, hapten, etc.), a me kekahi o nā mea maka no ka synthesis o dimethyl terephthalate, methyl methacrylate a me methyl acrylate.
2. ʻO ka noi nui o ka methanol ka hana o formaldehyde.
3. ʻO kekahi hoʻohana nui o ka methanol ka hana ʻana o ka acetic acid. Hiki iā ia ke hana i ka vinyl acetate, ka acetate fiber a me ka acetate, a me nā mea'ē aʻe. ʻO kāna koi e pili kokoke ana i nā pena, nā mea hoʻopili a me nā textiles.
4. Hiki ke hoʻohanaʻia ka Methanol e hana i ka methyl formate.
Hiki i ka 5.Methanol ke hana i ka methylamine, ʻo ka methylamine he amine momona nui, me ka nitrogen wai a me ka methanol e like me nā mea maka, hiki ke hoʻokaʻawale ʻia ma o ka hana ʻana no kahi methylamine, dimethylamine, trimethylamine, ʻo ia kekahi o nā kumu kumu kemika.
6. Hiki ke hoʻohuiʻia i loko o ka dimethyl carbonate, he huahana pili i ka nohona a hoʻohanaʻia i ka lāʻau lapaʻau, ka mahiʻai a me nāʻoihana kūikawā, a pēlā aku.
7. Hiki ke hoʻohui ʻia i loko o ka ethylene glycol, ʻo ia kekahi o ka petrochemical intermediate raw material a hiki ke hoʻohana ʻia i ka hana ʻana o ka polyester a me ka antifreeze.
8. Hiki ke hoʻohanaʻia i ka hanaʻana i ka mea hoʻoulu ulu, i mea e pono ai ka uluʻana o nā mea kanu maloʻo.
9.Also hiki ke synthesized methanol protein, methanol e like me maka mea i hanaia e ka microbial fermentation o ka methanol protein ua ikeia e like me ka lua o ka hanauna o hookahi-cell proteins, compaʻulaʻula me nā protein maoli, ʻoi aku ka waiwai o ka meaʻai, ʻoi aku ka kiʻekiʻe o ka ʻiʻo o ka protein ma mua o ka ʻai iʻa a me ka pīni soya, a he waiwai nui i nā amino acids, nā minerala a me nā huaora, hiki ke hoʻohana ʻia ma kahi o ka iʻa, soya beans, iwi ʻai. , ʻiʻo a me ka pauka waiu.
Hoʻohana ʻia ʻo 10.Methanol e like me ka hoʻomaʻemaʻe a me ka degreasing agent.
11. Hoʻohana ʻia ma ke ʻano he analytical reagent, e like me nā solvents, methylation reagents, chromatographic reagents. Hoʻohana pū ʻia i ka synthesis organik.
12. ʻO ka maʻamau ka methanol kahi mea hoʻoheheʻe ʻoi aku ka maikaʻi ma mua o ka ethanol, hiki ke hoʻoheheʻe i nā paʻakai inorganic he nui. Hiki ke hoʻohui ʻia i loko o ka ʻaila ma ke ʻano he wahie ʻokoʻa. Hoʻohana ʻia ka Methanol i ka hana ʻana i ka ʻaila octane additive methyl tertiary butyl ether, methanol gasoline, methanol fuel, a me methanol protein a me nā huahana ʻē aʻe.
ʻAʻole ʻo 13.Methanol wale nō kahi mea kemika koʻikoʻi, akā he kumu ikehu a me ka wahie kaʻa me ka hana maikaʻi loa. Hoʻopili ka Methanol me ka isobutylene no ka loaʻa ʻana o MTBE (methyl tertiary butyl ether), ʻo ia ka mea hoʻohui kiʻekiʻe octane unleaded gasoline a hiki ke hoʻohana ʻia ma ke ʻano he solvent. Eia kekahi, hiki ke hoʻohana ʻia e hana i nā olefins a me propylene.
14. Hiki ke hoʻohana ʻia ka Methanol e hana i ka dimethyl ether. ʻO ka wahie wai hou i hana ʻia me ka methanol a me ka dimethyl ether i hoʻokumu ʻia i kekahi ʻāpana i kapa ʻia ka wahie eter alkohol. ʻOi aku ka maikaʻi o ka hoʻopau ʻana a me ka wela ma mua o ke kinoea liquefied.
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2. E mālama i ke ahi a me ke kumu wela.
3. E hoʻopaʻa i ka pahu.
4. Pono e mālama kaʻawale mai ka wai, ethanol, ether, benzene, ketones, a ʻaʻole pono e hui pū ʻia.
5. Hoʻokuʻu i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana maʻalahi e hoʻohua i nā huna huna.
Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā lako hale kūpono.
