    Guryaha Kiimikada:

    Methanol (alkolada methyl, alkolada alwaax) ayaa si weyn loogu isticmaalaa dareeraha lacquers, rinjiga, varnishes, sibidhka, khadadka, midabada, balaastikada, iyo dahaarka warshadaha kala duwan.Tiro badan ayaa loo isticmaalaa soo saarista formaldehyde iyo kiimikooyinka kale ee laga soo saaro sida acetic acid, methyl halides iyo terephthalate, methyl methacrylate, iyo methylamines.Methanol sidoo kale waxaa loo isticmaalaa sidii wax lagu daro gaasaska, sida qayb ka mid ah khafiifiyeyaasha lacquer, diyaargarowga lidka-barafka ee nooca "aan joogtada ahayn", iyo diyaarinta kuleylka qasacadaysan ee khamriga jellied.Waxa kale oo loo istcimaalaa isku-duubnida dareeraha, rinji-saarayaasha, iyo walax nadiifin ahaan.Awoodda methanol ee beddelka mustaqbalka ee shidaalka waxay muujinaysaa in isticmaalka kiimikadani ay u badan tahay inuu kordho halkii uu yarayn lahaa.Heerkulka qolka, methanol waa dareere aan midab lahayn oo leh ur daran.Waa mid kacsan, cadaadiska uumiga ah 96 mmHg iyo cufnaanta uumiga 1.11.Waa lagu qallafsan yahay biyo waxayna ku milmi kartaa dareerayaasha kale ee dabiiciga ah.Waxaa laga helaa dabeecadda sida sheyga halsano ee alwaax iyo sida qayb ka mid ah miraha iyo khudaarta qaarkood.

     

    Codsiga:

    Methanol waa walxo kiimiko ah oo ceeriin ah oo muhiim u ah kiimikooyinka wanaagsan.Carbonylation-keeda 3.5 MPa iyo 180-200 ° C joogitaanka kicinta waxay soo saari kartaa acetic acid waxayna sii kordhin kartaa soo saarista acetic anhydride.Waxay la falgashaa syngas si ay u diyaariso vinyl acetate iyada oo ay jirto kicinta;waxay la falgashaa isobutylene si ay u soo saarto tert-butyl methyl ether;u diyaari dimethyl oxalate iyada oo loo marayo oxidization iyo carbonylation, iyo hydrogenation dheeraad ah si loo soo saaro glycol ethylene;waxay la falgashaa toluene oo hoos timaada kicinta iyo oxidization isku mar si ay u soo saarto aalkolada phenylethyl.Waxaa loo isticmaali karaa sida dareere wanaagsan, sida walxo cayriin ah, sida wakiilka ka-hortagga barafka, sida shidaalka iyo shidaalka lagu daro (tani waxay helaysaa dareenka sii kordhaya ee goobta ilaalinta deegaanka).Waa alaabta ceeriin ee ugu weyn ee diyaarinta formaldehyde, alaabta ceeriin ee daawada iyo soo saarista dhir udgoon, dareere ah ee midabada iyo warshadaha rinjiga, alaabta ceeriin ee diyaarinta methanol hal unug protein protein iyo synthesize of methyl ester.
