It is mainly used as an intermediate for preparing pesticides, agricultural chemicals and vitamin B6, and is used in a small amount for polymer production. used as plasticizer for alkyd resin, cross-linking agent for synthetic resin, bactericide, etc., and also used for making nylon, Medicine, 1, 4-butanediol and so on |
| üretim yöntemi | is obtained by catalytic hydrogenation of butynediol. After mixing a 40% aqueous solution of butynediol with 50% of Raney nickel, ammonia water as a inhibitor was added, and hydrogen was applied at a pressure of about 0.5MPa until the theoretical hydrogen absorption amount was reached. After filtration, the filtrate was distilled under reduced pressure, and the 110-114 ° C. (8kPa) fraction was collected to obtain butenediol. The preparation method is catalytic hydrogenation of 1, 4-butynediol to obtain 1, 4-butenediol. After mixing 40% aqueous butynediol solution with 50% Raney nickel, inhibitor ammonia water was added, and hydrogen gas was introduced at a pressure of about 0.5kPa until the theoretical hydrogen absorption amount was reached. After filtration, the filtrate was distilled under reduced pressure, and a fraction of 110 to 114 ° C./8kPa was collected to obtain 1, 4-butenediol. |
