| Ansökan | used as plasticizer of alkyd resin, crosslinking agent of synthetic resin, bactericide, etc, 1, 4-butenediol is a pesticide and pharmaceutical intermediate, which is used in the synthesis of organic chlorine pesticide endosulfan. 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 |
| production method | 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. |
