Meatotino o Meatotino ma Mausali:
O le vai manino e leai ni lanu, o lona ausa ma le ea e mafai ona fausia ni paluga pa, pe a susunuina e maua ai le mumu lanumoana. Mata'utia vevela 240.0°C; mamafa mamafa 78.5atm, miscible i le vai, ethanol, eter, benzene, ketones ma isi solvents organic. O lona ausa e fa'afefiloi ai mea pāpā ma le ea, lea e mafai ona fa'aoso ai le mu ma le pa pe a fa'aalia i le afi matala ma le vevela maualuga. E mafai ona tali malosi i le oxidant. Afai e fetaui ma le vevela maualuga, o le mamafa o loʻo i totonu o le atigipusa e faʻateleina, ma o loʻo i ai se lamatiaga o le taʻe ma le pa. Leai se mumu mumu pe a mu. E mafai ona fa'aputuina le eletise ma fa'amumu lona ausa.
Talosaga o Mea:
1.O se tasi o mea faʻapitoa faʻapitoa faʻapitoa, faʻaaogaina i le gaosiga o le chloromethane, methylamine ma le dimethyl sulphate ma le tele o isi mea faʻapitoa. O se mea mataʻutia foi mo vailaau faʻasaina (insecticides, acaricides), vailaʻau (sulfonamides, hapten, ma isi), ma se tasi o mea mataʻutia mo le faʻaogaina o le dimethyl terephthalate, methyl methacrylate ma methyl acrylate.
2.O le faʻaoga autu o le methanol o le gaosiga o formaldehyde.
3.O le isi faʻaoga tele o le methanol o le gaosiga o le acetic acid. E mafai ona maua ai le vinyl acetate, acetate fiber ma le acetate, ma isi. O lona manaʻoga e vavalalata vavalalata ma le vali, faʻapipiʻi ma ie.
4.Methanol e mafai ona faʻaaogaina e gaosia ai le methyl formate.
E mafai foi e le 5.Methanol ona gaosia le methylamine, o le methylamine o se amine gaʻo taua, faʻatasi ai ma le nitrogen vai ma le methanol e pei o mea mata, e mafai ona faʻamaonia e ala i le gaioiga mo se methylamine, dimethylamine, trimethylamine, o se tasi o mea faʻapitoa kemisi.
6. E mafai ona faʻapipiʻiina i le dimethyl carbonate, o se oloa faʻaleleia le siosiomaga ma faʻaaogaina i vailaʻau, faʻatoʻaga ma pisinisi faʻapitoa, ma isi.
7. E mafai ona faʻapipiʻiina i totonu o le ethylene glycol, o se tasi lea o mea faʻapipiʻi vavalo petrochemical ma e mafai ona faʻaaogaina i le gaosiga o le polyester ma le antifreeze.
8.E mafai ona faʻaaogaina i le gaosiga o le faʻalauteleina o le tuputupu aʻe, lea e aoga i le tuputupu aʻe o fualaʻau matutu.
9.Also e mafai ona synthesized methanol polotini, methanol e pei o mea mata gaosia e microbial fermentation o methanol porotini ua lauiloa o le tupulaga lona lua o porotini sela tasi, compamumu ma polotini faanatura, e maualuga atu le tau o mea'ai, e sili atu le maualuga o mea e maua mai i le palatini, nai lo i'a ma pi soya, ma e mauoa i amino acids, minerale ma vaitamini, lea e mafai ona fa'aaogaina e sui ai le i'a, pi soya, ponaivi. , aano o manufasi ma le susu susu pauta.
10.Methanol o loʻo faʻaaogaina e pei o le faʻamamaina ma le degreasing sui.
11. Faʻaaogaina e avea o se suʻesuʻega faʻapitoa, e pei o solvents, methylation reagents, chromatographic reagents. Fa'aoga fo'i i le fa'aogaina o meaola.
12. E masani lava o le methanol o se solvent sili atu nai lo le ethanol, e mafai ona faʻaumatia le tele o masima inorganic. E mafai foi ona fa'afefiloi i le penisini e fai ma isi suau'u. O le Methanol e fa'aaogaina i le gaosiga o le penisini octane additive methyl tertiary butyl ether, methanol gasoline, methanol fuel, ma methanol protein ma isi oloa.
13.Methanol e le gata o se vailaʻau mataʻutia taua, ae faʻapea foʻi ma se puna malosi ma le suauu taʻavale ma le faʻatinoina lelei. O le Methanol e tali atu i le isobutylene e maua ai le MTBE (methyl tertiary butyl ether), o se mea fa'apipi'i penisini e leai ni ta'ita'i maualuga ma e mafai fo'i ona fa'aaoga e fai ma so'o. E le gata i lea, e mafai foi ona faʻaaogaina e gaosia ai olefins ma propylene.
14.Methanol e mafai ona faʻaaogaina e gaosia ai le dimethyl ether. O le suau'u vai fou e faia i le methanol ma le dimethyl ether ua fa'atulagaina i se vaega fa'apitoa e ta'ua o le suau'u ether alcohol. O lona fa'avevelaina lelei ma le fa'avevela e maualuga atu nai lo le kasa fa'afefeteina.
Oloa Teuina Faamatalaga:
1. Teu i totonu ose faleteuoloa malulu, fa'aalili.
2. Taofi ese mai le afi ma le vevela.
3. Faamau le koneteina.
4. E tatau ona teuina ese mai le vai, ethanol, eter, benzene, ketones, ma e le tatau ona faʻafefiloi.
5. Faʻasaina le faʻaogaina o masini masini ma meafaigaluega e faigofie ona faʻatupu ai aloiafi.
O le nofoaga e teu ai e tatau ona faʻapipiʻiina i masini faʻalavelave faʻafuaseʻi liki ma mea e malu ai.
