Whakaahuatanga Hua:
Ko te Methanol, e mohiotia ana ko te hydroxymethane, he puhui pararopi me te waipiro mono tino ngawari i roto i te hanganga.Ko tana tātai matū ko CH3OH/CH₄O, ko CH₃OH te hanga poto, ka taea te whakaatu i te roopu hydroxyl o te methano.No te mea i kitea tuatahi i roto i te whakamaroketanga maroke o te rakau, kei te mohiotia ano ko & ldquo;waipiro rakau & rdquo;ranei & ldquo;wairua rakau & rdquo;.Ko te horopeta iti rawa o te pahana waha tangata e pa ana ki te 100mg/kg te taumaha tinana, ko te horomanga waha o te 0.3 ~ 1g/kg ka mate.Ka whakamahia i roto i te hanga formaldehyde me te pesticides, me etahi atu, ka whakamahia hei tangohanga o te mea pararopi me te whakangao waipiro, aha atu. Ko te nuinga o nga wa ka mahia nga hua kua oti ma te tauhohe i te waro monoxide ki te hauwai.
Ngā Āhuatanga Hua me te Pūmautanga:
Ko te wai marama kore tae, ko tana kohu me te hau ka hanga ranunga pahū, ina tahuna kia puta te mura puru.Te pāmahana tino nui 240.0°C;pehanga arohaehae 78.5atm, miscible ki te wai, waiwaro, etera, benzene, ketones me etahi atu whakarewa pararopi.Ko tana kohu ka hanga i te ranunga pahū me te hau, ka puta te ngingiha me te pahū ina pa ana ki te ahi tuwhera me te wera nui.Ka kaha te tauhohe ki te hāora.Mena ka pa ki te wera nui, ka piki te pehanga o roto i te ipu, ka tupono ka pakaru me te pahū.Kaore he mura marama i te wa e wera ana.Ka taea te whakaemi i te hiko pateko me te mura o tana kohu.
Taupānga Hua:
1.Ko tetahi o nga rauemi mata waro, whakamahia i roto i te hanga o te chloromethane, te methylamine me te dimethyl sulphate me te maha atu o nga hua pararopi.He rauemi mata ano mo te pesticides (nga pepeke, acaricides), nga rongoa (sulfonamides, hapten, me etahi atu), me tetahi o nga rauemi mata mo te whakahiato o te dimethyl terephthalate, methyl methacrylate me te methyl acrylate.
2.Ko te whakamahinga matua o te methanol ko te hanga o te formaldehyde.
3.Ko tetahi atu whakamahinga nui o te methanol ko te hanga o te waikawa acetic.Ka taea e ia te whakaputa i te vinyl acetate, te muka acetate me te acetate, me etahi atu. Ko tana tono e hono tata ana ki te peita, te whakapiri me nga kakano.
Ka taea te whakamahi 4.Methanol ki te hanga methyl formate.
Ka taea ano e te 5.Methanol te hanga i te methylamine, ko te methylamine he amine momona nui, me te hauota wai me te methanol hei rauemi mata, ka taea te wehewehe ma te tukatuka mo te methylamine, te dimethylamine, te trimethylamine, ko tetahi o nga rauemi matū taketake.
6.Ka taea te whakauru ki te dimethyl carbonate, he hua taiao me te whakamahi i te rongoa, te ahuwhenua me nga ahumahi motuhake, me era atu.
7.Ka taea te whakauru ki roto i te ethylene glycol, koinei tetahi o nga rauemi matawai takawaenga petrochemical ka taea te whakamahi i te hanga o te polyester me te antifreeze.
8.Ka taea te whakamahi i roto i te hanga o te whakatairanga tipu, e whai hua ana ki te tipu o nga hua whenua maroke.
9.Ka taea hoki te synthesized methanol pūmua, methanol rite rauemi mata whakaputaina e te FERMENTATION microbial o te pūmua methanol e mohiotia ana ko te reanga tuarua o te pūmua pūtau kotahi, compahe whero me nga pūmua taiao, he nui ake te uara kai, he nui ake te ihirangi pūmua masivesivá i tera o te kai ika me te pini soya, he nui hoki nga waikawa amino, nga kohuke me nga huaora, ka taea te whakamahi hei whakakapi i te kai ika, te pini soya, te kai wheua. , te mīti me te paura miraka.
Ka whakamahia te 10.Methanol hei kai horoi me te whakaheke.
11.I whakamahia hei reagent tātari, penei i te whakarewa, te methylation reagents, te reagents chromatographic.Ka whakamahia ano i roto i te whakahiato waro.
12. Ko te tikanga he whakarewa pai ake te mewaro i te waiwaro, ka taea te whakakore i te maha o nga tote parakore.Ka taea hoki te whakakotahi ki te penehīni hei wahie kē.Ka whakamahia te Methanol i roto i te hanga penehīni octane tāpiritanga methyl tertiary butyl ether, methanol penehīni, methanol wahie, me te methanol pūmua me ētahi atu hua.
Ko te 13.Methanol ehara i te mea he matū matū noa, engari he puna hiko me te wahie waka me te mahi pai.Ka tauhohe te Methanol me te isobutylene ki te whiwhi MTBE (methyl tertiary butyl ether), he taapiri penehīni kore-arahi teitei-octane ka taea hoki te whakamahi hei whakarewa.I tua atu, ka taea hoki te whakamahi ki te whakaputa olefins me te propylene.
Ka taea te whakamahi 14.Methanol ki te whakaputa i te dimethyl ether.Ko te wahie wai hou i hangaia mai i te methanol me te dimethyl ether i hangaia i roto i tetahi waahanga ka kiia ko te waipiro ether hinu.He teitei ake te pai o te ngingiha me te kaha o te waiariki i tera o te hau liquefied.
Nga Tuhipoka Rokiroki Hua:
1. Rokiroki i roto i te whare putunga hauhautanga, whai hau.
2.Kia matara atu i te ahi me te puna wera.
3. Kia hiritia te ipu.
4.Me penapena motuhake mai i te wai, te waihano, te etera, te benzene, te ketones, kaua rawa e uru.
5.Ka aukati i te whakamahi i nga taputapu miihini me nga taputapu e ngawari ana ki te whakaputa korakora.
Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere pakaru me nga taonga whakaruru tika.
