Nzira yekugadzira ye1,4-butynediol:
Iyo acetylene formaldehyde synthesis nzira inogamuchirwa.Iyo acetylene ine 80% -90% yakatsikirirwa kune kumanikidzwa kwe0.4-0.5mpa, preheated kusvika 70-80 ℃ uye inotumirwa kune reactor.Chigadzirwa chisina kuchena chinowanikwa nekuita ne formaldehyde pa 110-112 ℃ ine butyne sechikonzero.Chigadzirwa chekuita chinomisikidzwa uye chakanatswa kuti uwane chigadzirwa chakapedzwa, uye iyo byproduct ndeye propargyl doro.
paraformaldehyde inoshandiswa seyakabikwa, cyclohexanone inoshandiswa se solvent, acetylene inounzwa mureactor pamberi pecatalyst acetylene mhangura, uye tembiricha inochengetwa pa115-120 ℃.Mushure mekunge formaldehyde yashandurwa zvachose, acetylene inomiswa, iyo catalyst inosefa kunze, uye mhinduro yekugadzirisa inoiswa uye yakagadziridzwa zvakare kuti iwane crystalline 1,4-butynediol.
Kuonekwa kwe1,4-butynediol: chena kana mwenje yero crystal chena rhombic crystal (yero yero mushure mekutora mwando)
Chinese alias: 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 chiito chinangwa:
1,4-butynediol inogona kushandiswa kugadzira butene glycol, butanediol γ- Mutsara wezvigadzirwa zvemakemikari zvakadai sebutyrolactone zvinogonawo kushandiswa kugadzira mutsara wezvinhu zvakakosha zvakadai sebutene glycol, butylene glycol uye n-butanol, nezvimwe. kugadzira mapurasitiki ekugadzira uye shinda dzekugadzira;
1,4-butynediol pachayo inonyungudutsa yakanaka.Inoshandiswa sechinhu chinopenya muindasitiri ye electroplating uye seyepakati mune organic synthesis uye zvinhu zvechiridzwa electroplating.
