Gaosiga auala ole 1,4-butynediol:
O le acetylene formaldehyde synthesis method ua fa'aaogaina.O le acetylene o loʻo i ai le 80% -90% o loʻo faʻapipiʻiina i le mamafa o le 0.4-0.5mpa, faʻamalo i le 70-80 ℃ ma auina atu i le reactor.O le oloa fa'atauva'a e maua e ala i le tali atu i formaldehyde i le 110-112 ℃ fa'atasi ai ma le butyne e fai ma fa'amalosi.E fa'atumauina ma fa'amamā le mea fa'afofoga ina ia maua ai le 'oloa mae'a, ma o le mea fa'asolo ole propargyl alcohol.
e fa'aaogaina paraformaldehyde e fai ma mea mata, o le cyclohexanone e fa'aaogaina e pei o le solvent, o le acetylene e fa'afeiloa'i i totonu o le reactor i le i ai o le catalyst acetylene copper, ma o le vevela e tausia i le 115-120 ℃.A maeʻa ona liua atoatoa formaldehyde, taofi le acetylene, faʻamama ese le faʻamalosi, ma faʻapipiʻi le tali tali ma toe faʻasalaina e maua ai le tioata 1,4-butynediol.
Fa'aaliga o le 1,4-butynediol: pa'epa'e po'o le samasama samasama tioata pa'epa'e rhombic tioata (samasama malamalama pe a uma le susu)
igoa Saina: 1,4-butynediol;BOZ;2-butyne-1,4-diol electroplating luminescent sui;1,4-butynediol;1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;2-butyne-1,4-diol.
1,4-butynediol faʻamoemoega gaioiga:
1,4-butynediol e mafai ona faʻaaogaina e gaosia ai le butene glycol, butanediol γ- E mafai foi ona faʻaaogaina se faasologa o vailaʻau faʻapitoa e pei ole butyrolactone e gaosia ai se faasologa o mea taua e pei ole butene glycol, butylene glycol ma le n-butanol, ma isi mea. ia gaosia palasitika gaosia ma filo faʻapipiʻi;
1,4-butynediol lava ia o se solvent lelei.E faʻaaogaina e avea o se faʻamalamalamaga i totonu o le eletise eletise ma o se mea faʻapitoa i le faʻaogaina o meaola ma se mea mo le faʻaogaina o meafaigaluega.
