Indlela yokuvelisa ye-1,4-butynediol:
Indlela ye-acetylene formaldehyde synthesis yamkelwe.I-acetylene equkethe i-80% -90% ixinzelelwe kuxinzelelo lwe-0.4-0.5mpa, i-preheated ukuya kwi-70-80 ℃ kwaye ithunyelwe kwi-reactor.Imveliso ekrwada ifunyanwa ngokusabela nge formaldehyde ku 110-112 ℃ kunye ne butyne njenge catalyst.Imveliso yokusabela igxininiswe kwaye ihlanjululwe ukufumana imveliso egqityiweyo, kwaye i-byproduct yi-propargyl alcohol.
I-paraformaldehyde isetyenziswa njengento eluhlaza, i-cyclohexanone isetyenziswa njenge-solvent, i-acetylene ifakwe kwi-reactor phambi kwe-catalyst acetylene copper, kwaye ubushushu bugcinwa kwi-115-120 ℃.Emva kokuba i-formaldehyde iguqulwe ngokupheleleyo, i-acetylene imisiwe, i-catalyst iyahluzwa, kwaye isisombululo sokuphendula sigxininiswe kwaye siphinde sihlaziywe ukuze sifumane i-crystalline 1,4-butynediol.
Imbonakalo ye-1,4-butynediol: ikristale emhlophe okanye ekhanyayo etyheli emhlophe ye-rhombic (etyheli elikhanyayo emva kokufunxa ukufuma)
Isi-Chinese alias: 1,4-butynediol;BOZ;I-2-butyne-1,4-diol i-agent ye-luminescent ye-electroplating;1,4-butynediol;I-1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;I-2-butyne-1,4-diol.
Injongo yesenzo se-1,4-butynediol:
I-1,4-butynediol ingasetyenziselwa ukuvelisa i-butene glycol, i-butanediol γ- Uluhlu lweemveliso zeekhemikhali ezifana ne-butyrolactone nazo zingasetyenziselwa ukuvelisa uluhlu lweemveliso ezibalulekileyo ezifana ne-butene glycol, i-butylene glycol kunye ne-n-butanol, kunye nokunye. ukwenza iiplastiki zokwenziwa kunye neentsinga zokwenziwa;
I-1,4-butynediol ngokwayo isinyibilikisi esihle.Isetyenziswe njengento ekhanyayo kwishishini le-electroplating kwaye njengendawo ephakathi kwi-organic synthesis kunye nesixhobo se-electroplating yesixhobo.
