ʻO ke ʻano hana o 1,4-butynediol:
Hoʻohana ʻia ke ʻano hana synthesis acetylene formaldehyde.Hoʻopili ʻia ka acetylene i loko o 80% -90% i ke kaomi o 0.4-0.5mpa, preheated i 70-80 ℃ a hoʻouna ʻia i ka reactor.Loaʻa ka huahana maʻemaʻe ma ka hana ʻana me formaldehyde ma 110-112 ℃ me ka butyne ma ke ʻano he catalyst.Hoʻopili ʻia ka huahana hopena a hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o ka huahana i hoʻopau ʻia, a ʻo ka huahana ka propargyl alcohol.
Hoʻohana ʻia ka paraformaldehyde e like me ka mea maka, hoʻohana ʻia ʻo cyclohexanone e like me ka solvent, hoʻokomo ʻia ka acetylene i loko o ka reactor i mua o ka catalyst acetylene copper, a mālama ʻia ka mahana ma 115-120 ℃.Ma hope o ka hoʻololi ʻia ʻana o ka formaldehyde, hoʻopau ʻia ka acetylene, kānana ʻia ka catalyst, a hoʻopaʻa ʻia ka hopena hopena a hana hou ʻia e loaʻa ka crystalline 1,4-butynediol.
ʻO ka hiʻohiʻona o 1,4-butynediol: keʻokeʻo a i ʻole ke aniani melemele keʻokeʻo keʻokeʻo rhombic crystal (melemele māmā ma hope o ka lawe ʻana o ka wai)
ʻO ka inoa Kina: 1,4-butynediol;BOZ;2-butyne-1,4-diol electroplating luminescent agent;1,4-butynediol;1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;2-butyne-1,4-diol.
1,4-butynediol kumu hana:
Hiki ke hoʻohana ʻia ka 1,4-butynediol e hana i ka butene glycol, butanediol γ- Hiki ke hoʻohana ʻia ke ʻano o nā huahana kemika e like me butyrolactone no ka hana ʻana i nā ʻano huahana koʻikoʻi e like me butene glycol, butylene glycol a me n-butanol, a ʻoi aku. e hana i nā plastic synthetic a me nā fiber synthetic;
ʻO 1,4-butynediol pono'ī he mea hoʻoheheʻe maikaʻi.Hoʻohana ʻia ia ma ke ʻano he mea hoʻomālamalama i ka ʻoihana electroplating a ma ke ʻano he waena i ka synthesis organik a me kahi mea no ka electroplating mea kani.
