Tikanga whakaputa 1,4-butynediol:
Ka whakamahia te tikanga whakahiato acetylene formaldehyde.Ko te acetylene kei roto i te 80% -90% ka pehia ki te pehanga o te 0.4-0.5mpa, ka whakamahana ki te 70-80 ℃ ka tukuna ki te reactor.Ka whiwhi te hua masivesivá ma te tauhohe ki te formaldehyde i te 110-112 ℃ me te butyne hei whakakōkī.Ko te hua tauhohenga ka whakakoi, ka parahia kia whiwhi ai i te hua kua oti, a ko te hua he waipiro propargyl.
Ka whakamahia te paraformaldehyde hei rauemi mata, ka whakamahia te cyclohexanone hei whakarewa, ka whakauruhia te acetylene ki roto i te reactor i te aroaro o te konukura acetylene whakakōkī, ka pupurihia te pāmahana ki te 115-120 ℃.I muri i te whakahuritanga o te formaldehyde, ka mutu te acetylene, ka tātarihia te whakakorikori, ka kukū te otinga tauhohenga me te whakahiato kia whiwhi 1,4-butynediol tioata.
Te ahua o te 1,4-butynediol: he ma, he kowhai kowhai marama ranei te karaihe rhombic ma (he kowhai marama i muri i te whakauru makuku)
ingoa Hainamana: 1,4-butynediol;BOZ;2-butyne-1,4-diol electroplating kaihoko luminescent;1,4-butynediol;1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;2-butyne-1,4-diol.
1,4-butynediol kaupapa mahi:
Ka taea te whakamahi i te 1,4-butynediol ki te whakaputa i te butene glycol, te butanediol γ- Ka taea hoki te whakamahi i te raupapa o nga hua matū penei i te butyrolactone ki te hanga i te raupapa o nga hua waro nui penei i te butene glycol, butylene glycol me te n-butanol, me etahi atu ki te hanga kirihou waihanga me nga muka waihanga;
Ko te 1,4-butynediol ano he whakarewa pai.Ka whakamahia hei whakamarama i roto i te ahumahi whakakikorua hiko me te takawaenga i roto i te whakahiato pararopi me te rauemi mo te taputapu hiko.
