Productionis methodus 1,4-butynediol:
Acetylene formaldehyde synthesis methodo adoptatur.Acetylenum continens 80%-90% comprimitur pressioni 0.4-0.5mpa, preheated ad 70-80 ℃ et ad reactori mittitur.Rude productum obtinetur reagens cum formaldehyde in 110-112 cum butyne ut catalyst.Productum reactionem coactum et conflatum ad opus operis obtinendum est, ac byproductum est alcohol propargylum.
paraformaldehyde ut materia rudis adhibetur, cyclohexanone pro solvendo adhibetur, acetylene in reactorem introducitur coram catalysto acetylene aeris, et temperatura ad 115-120 servatur.Postquam formaldehyde perfecte convertitur, acetylene sistitur, catalysta eliquata est, et solutio reactio coacta et recrystallata ad crystallinum obtinendum 1,4-butynediolum obtinet.
Aspectus 1,4-butynediol: albus vel lux flavo crystallum album rhombicum crystallum (lucis luteum post humorem effusio)
Seres alias: 1,4-butynediol;BOZ;2-butyne-1,4-diolo electroplatante lucidum agens;1,4-butynediol;1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;2-butyne-1,4-diol.
1,4-butynediol actio propositi;
1,4-butynediolum ad producendum glycol butene, butanediolum γ- Series chemicorum productorum ut butyrolactone adhiberi potest etiam ad seriem productorum organicorum magni ponderis, ut butene glycol, butylene glycol et n-butanol. fabricare syntheticas materias et fibras syntheticas;
1,4-butynediol ipsa bona locuples est.In electroplatandi industria lucidior adhibetur, et ut medium in synthesi organica et materia instrumenti electroplating.
