Mokhoa oa tlhahiso ea 1,4-butynediol:
Mokhoa oa acetylene formaldehyde synthesis o amohetsoe.Acetylene e nang le 80% -90% e hatelloa ho khatello ea 0.4-0.5mpa, e futhumetseng ho ea ho 70-80 ℃ ebe e romelloa ho reactor.Sehlahisoa se tala se fumanoa ka ho arabela ka formaldehyde ho 110-112 ℃ le butyne e le mokelikeli.Sehlahisoa sa karabelo se tsepamisitsoe ebile se hloekisoa ho fumana sehlahisoa se felileng, 'me sehlahisoa ke joala ba propargyl.
paraformaldehyde e sebelisoa e le lisebelisoa tse tala, cyclohexanone e sebelisoa e le solvent, acetylene e kenngoa ka har'a reactor ka pel'a catalyst acetylene koporo, 'me mocheso o bolokiloe ho 115-120 ℃.Ka mor'a hore formaldehyde e fetohe ka ho feletseng, acetylene e emisoa, motsoako o sefshoa, 'me tharollo ea karabelo e tsepamisitsoe le ho tsosolosoa hape ho fumana crystalline 1,4-butynediol.
Ponahalo ea 1,4-butynediol: kristale e tšoeu kapa e mosehla o mosehla oa rhombic (e mosehla o mosehla ka mor'a ho kenngoa ha mongobo)
