nuntium

Consectetur in productione alcoholi propargyli, 1,4 butynediolum et 3-chloropropynum

1,4-zona

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.

1,4-butynediol zone2
1,4-zona

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.
