Ibisobanuro ku bicuruzwa:
Methanol, izwi kandi nka hydroxymethane, ni ifumbire mvaruganda kandi inzoga ya mono yoroshye cyane mu miterere. Imiti yimiti ni CH3OH / CH₄O, muriyo CH₃OH nuburyo bugufi bwubatswe, bushobora kwerekana hydroxyl groupe ya methano. Kuberako yabonetse bwa mbere mugukata ibiti byumye, bizwi kandi nka & ldquo; inzoga zo mu giti & rdquo; cyangwa & ldquo; umwuka wibiti & rdquo;. Igipimo cyo hasi cyuburozi bwabantu ni hafi 100mg / kg uburemere bwumubiri, gufata umunwa 0.3 ~ 1g / kg birashobora kwica. Ikoreshwa mugukora fordehide na pesticide, nibindi, kandi bigakoreshwa mugukuramo ibintu kama na alcool denaturant, nibindi .. Ibicuruzwa byarangiye mubisanzwe bikorwa mugukora monoxide ya karubone hamwe na hydrogen.
Ibicuruzwa byiza nibihamye:
Amazi meza atagira ibara, imyuka hamwe numwuka birashobora gukora imvange ziturika, iyo bitwitswe kugirango bitange urumuri rwubururu. Ubushyuhe bukabije 240.0 ° C; umuvuduko ukabije 78.5atm, utabangamiwe namazi, Ethanol, ether, benzene, ketone nindi mashanyarazi. Umwuka wacyo ukora imvange iturika hamwe numwuka, bishobora gutera gutwikwa no guturika mugihe uhuye numuriro ufunguye nubushyuhe bwinshi. Irashobora kwitwara neza hamwe na okiside. Niba ihuye nubushyuhe bwinshi, umuvuduko uri muri kontineri uriyongera, kandi hari akaga ko guturika no guturika. Nta muriro ugurumana iyo waka. Irashobora kwegeranya amashanyarazi ahamye no gutwika imyuka yayo.
Gusaba ibicuruzwa:
1.Bimwe mubikoresho fatizo byibanze, bikoreshwa mugukora chloromethane, methylamine na dimethyl sulfate nibindi bicuruzwa byinshi kama. Nibikoresho fatizo byica udukoko (udukoko twica udukoko, acariside), imiti (sulfonamide, hapten, nibindi), hamwe nimwe mubikoresho fatizo byo guhuza dimethyl terephthalate, methyl methacrylate na methyl acrylate.
2.Ikoreshwa nyamukuru rya methanol ni umusaruro wa fordehide.
3.Ubundi buryo bukomeye bwo gukoresha methanol ni ugukora aside irike. Irashobora gutanga vinyl acetate, fibre acetate na acetate, nibindi. Ibisabwa byayo bifitanye isano rya bugufi nibisiga amarangi, ibifunga hamwe nimyenda.
4.Methanol irashobora gukoreshwa mugukora methyl.
5.Methanol irashobora kandi gukora methylamine, methylamine ni amine yingenzi yibinure, hamwe na azote yuzuye na methanol nkibikoresho fatizo, birashobora gushishoza binyuze mugutunganya methylamine, dimethylamine, trimethylamine, nikimwe mubikoresho fatizo bya shimi fatizo.
6.Ishobora guhurizwa muri karubone ya dimethyl, nigicuruzwa cyangiza ibidukikije kandi gikoreshwa mubuvuzi, ubuhinzi ninganda zidasanzwe, nibindi.
7.Bishobora guhurizwa muri Ethylene glycol, ikaba ari kimwe mubikoresho bya peteroli hagati ya peteroli kandi bishobora gukoreshwa mugukora polyester na antifreeze.
8.Bishobora gukoreshwa mugukora iterambere ryiterambere, rifitiye akamaro imikurire y ibihingwa byumye.
9.Ikindi kandi gishobora guhindurwamo poroteyine ya methanol, methanol nkibikoresho fatizo bikozwe na fermentation ya mikorobe ya poroteyine ya methanol izwi nkigisekuru cya kabiri cya poroteyine imwe, compaumutuku hamwe na poroteyine karemano, agaciro k'imirire ni hejuru, intungamubiri za poroteyine ziri hejuru cyane ugereranije n'iz'amafi n'ibishyimbo bya soya, kandi bikungahaye kuri aside amine, imyunyu ngugu na vitamine, zishobora gukoreshwa mu mwanya w'amafi, ibishyimbo bya soya, ifunguro ry'amagufwa , inyama n'ifu y'ifu.
10.Methanol ikoreshwa nk'isuku no gutesha agaciro.
11.Bikoreshwa nka reagent yisesengura, nkibishishwa, methylation reagents, chromatographic reagents. Ikoreshwa kandi muri synthesis.
12.Ubusanzwe methanol nigisubizo cyiza kuruta Ethanol, irashobora gushonga imyunyu ngugu myinshi. Irashobora kandi kuvangwa muri lisansi nkibindi bicanwa. Methanol ikoreshwa mugukora lisansi octane yongeyeho methyl tertiary butyl ether, lisansi ya methanol, lisansi ya methanol, na proteine methanol nibindi bicuruzwa.
13.Methanol ntabwo ari ibikoresho byingenzi bya shimi gusa, ahubwo ni isoko yingufu na lisansi yimodoka ifite imikorere myiza. Methanol ifata isobutylene kugirango ibone MTBE (methyl tertiary butyl ether), ikaba ari octane yo mu bwoko bwa octane yongewemo lisansi kandi ishobora no gukoreshwa nk'umuti. Mubyongeyeho, irashobora kandi gukoreshwa mugukora olefine na propylene.
14.Methanol irashobora gukoreshwa mugukora dimethyl ether. Amavuta mashya y'amazi akozwe muri methanol na dimethyl ether yakozwe muburyo runaka yitwa amavuta ya alcool. Gukora neza kwayo hamwe nubushyuhe bwo hejuru birarenze ibya gaze ya lisansi.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Komeza ikintu gifunze.
4.Bigomba kubikwa bitandukanye n'amazi, Ethanol, ether, benzene, ketone, kandi ntibigomba na rimwe kuvangwa.
5.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
Ahantu ho guhunika hagomba kuba harimo ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
