Joala, methyl

Methylene joala (kapa methanol) ke mokelikeli colorless. Ho habonolo miscible ka metsi le solvents tse fapa-fapaneng le e motheong oa manyolo. Tatso le monko oa methylene joala (CH3OH moralo) e na le hoo e ka bang ha ho na phapang e tsoang ethyl, empa ho ke ke nang le chefo e le ka etsa hore chefo haholo. Methanol na le e tlase e belang ntlha. Ho 64,5 likhato Celsius. Ha tukang boitsebiso bona e na le palo 'mala e putsoa ea lelakabe le se smokes.

Tlas'a maemo a tlhaho, ke ke ha khoneha ho fumana methanol ka mahala foromo. Ka tlhaho, ho na le, methyl joala derivatives feela, e leng Ester oli le dintho. Ba fumaneha hohle. Anthranilic acid e, methyl Ester e leng ka oli jasmine le salicylic - ka oli wintergreen. Derivatives tsa methanol fumanoa ka alkaloids, lidae tsa tlhaho, joalo-joalo

Pele ho fumana methanol hlahiswa nakong ea omileng distillation thulaganyong, lintho tse bonahalang lehong tala. Morao-rao bahlahisi liindasteri sebelisa mekhoa maiketsetso.

Methylene joala ho pharaletseng sebelisoa ka solvent tsa pente le lipolisheng. E sebelisoa e le setho qalang ho hlahisa formaldehyde, dimethyl sulfate, chloride methylene, le metsoako e meng e hlahisoang ke ho bolela lik'hemik'hale. Hape, ho ke e 'ngoe ea likarolo antifreeze le e sebediswa bakeng sa denaturing ethyl joala.

Methanol ke chefo, e leng e sebetsa ho le vascular le tsamaiso ea methapo. The toxicity ea ntho e loketseng ho ho kena moea lona ha ingested le sokolohela formaldehyde beha bophelo kotsing.

Methylene joala chefo eo ka etsahala ka mor'a ho amohela dimililitha hlano ho isa ho tse leshome e etsa hore bofofu batho. lethal dose A feteng dikgerama mashome a mararo, hangata sesosa sa lefu, e leng le hlaha ka tšitiso ea tsamaiso ea matšoafo, matšoafo edema kapa boko le uremia kapa putlama. Matšoao a bonolo chefo methanol a ka hlaha:

• hlooho;
• kakaretso malaise;
• bofokoli;
• ho nyekoa ke pelo;
• chills;
• ho hlatsa.

Kahoo, kotsi bophelo hase feela, methyl joala foromo e hloekileng, empa hape motsoako leo ho lona ho dikahare methanol ke tse nyenyane. Rasiti ea ntho tse chefo 'meleng ka nka sebaka sa feela ka tsamaiso tshilong ya dijo. para joala phunyeletse matšoafo. Methanol ka tekanyo e sa reng letho ke khona ho phunyeletse ka 'mele' me ka letlalo.

Methylene joala linaheng tse ling e sebelisoa e le denaturant bakeng ethanol elements. La sephetho itsoara joang ka tsa ntho lik'hemik'hale ke karolo ea lithethefatsi hlahiswa ho indasteri e nkhang hamonate. molao Russia e hanela ho sebelisoa ha methanol ka lihlahisoa ne a rerile hore tshebediso ya batho ba bangata.

Methylene joala ke e sebelisa e le lipakeng tsa synthesizing le bongata ba indasteri ea liindasteri lik'hemik'hale. Ka motheong oa lona ho polymers hlahisoa, 'me tse fapa-fapaneng lintho tse phelang. Methanol ho pharaletseng sebelisoa e le moemeli bakeng sa ba lokisetsa ho ea mefuta e itseng ea chefo e bolaeang likokoanyana.

Methylene joala ke lintho tse bonahalang e tala bakeng sa ho hlahisa methylamine, pentaerythritol, le hexamine. tšebeliso ea eona e leng tlhahiso ea polyvinylchloride, Ion phapanyetsano le urea halogenated, hammoho le ka tlhahisong ea filimi ea lifoto. Ntle methanol e ke ke ea sebetsa dimela ammonia. Methylene joala ho pharaletseng sebediswa ho indasteri e etsang meriana ka tlhahisong ea meriana. mokelikeli ona li ka sebelisoa e le mafura a ka dimela matla, ho ba le ka nkang sebaka sa likoloi peterole. Ntle methanol e sa hlahiswa acid e acetic le rabara maiketsetso. ntho ena e boetse e fumana kopo lona ho indasteri le oli le khase e rarahaneng ya dintho.
