E sebetsa ka ho khetheha tlhahisong ea joala ea propargyl, 1,4 butynediol le 3-chloropropyne.

Sebaka sa 1,4-butynediol

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.
