Indlela yokukhiqiza ye-1,4-butynediol:
Indlela ye-acetylene formaldehyde synthesis yamukelwa.I-acetylene equkethe u-80% -90% icindezelwa ku-0.4-0.5mpa, ishiselwe ku-70-80 ℃ futhi ithunyelwe ku-reactor.Umkhiqizo ongahluziwe utholakala ngokusabela nge-formaldehyde ku-110-112 ℃ ne-butyne njenge-catalyst.Umkhiqizo wokusabela ugxilisiwe futhi ucwengisiswe ukuze uthole umkhiqizo oqediwe, futhi i-byproduct i-propargyl alcohol.
I-paraformaldehyde isetshenziswa njengempahla eluhlaza, i-cyclohexanone isetshenziswa njenge-solvent, i-acetylene ifakwa ku-reactor phambi kwe-catalyst acetylene yethusi, futhi izinga lokushisa ligcinwa ku-115-120 ℃.Ngemuva kokuthi i-formaldehyde iguqulwe ngokuphelele, i-acetylene iyamiswa, i-catalyst iyahlungwa, futhi isisombululo sokusabela sigxiliwe futhi siphinde sifakwe kabusha ukuze kutholwe i-crystalline 1,4-butynediol.
Ukubukeka kwe-1,4-butynediol: ikristalu emhlophe noma ephuzi ekhanyayo emhlophe ye-rhombic (ophuzi okhanyayo ngemva kokumuncwa komswakama)
Isibizo sesiShayina: 1,4-butynediol;BOZ;I-agent ye-luminescent engu-2-butyne-1,4-diol electroplating;1,4-butynediol;I-1,4-dihydroxy-2-butyne;i-dihydroxy dimethyl acetylene;i-dihydroxymethyl acetylene;2-butyne-1,4-diol.
Inhloso yesenzo se-1,4-butynediol:
I-1,4-butynediol ingasetshenziselwa ukukhiqiza i-butene glycol, i-butanediol γ- Uchungechunge lwemikhiqizo yamakhemikhali efana ne-butyrolactone ingasetshenziswa futhi ukwenza uchungechunge lwemikhiqizo ebalulekile ye-organic efana ne-butene glycol, i-butylene glycol ne-n-butanol, nokunye. ukwenza amapulasitiki okwenziwa kanye nemicu yokwenziwa;
I-1,4-butynediol ngokwayo iyi-solvent enhle.Isetshenziswa njenge-brightener embonini ye-electroplating futhi njengendawo ephakathi ku-organic synthesis kanye nempahla ye-electroplating yensimbi.
