- Preparation method of butanediol bis(propionitrile) ether
-
The invention discloses a preparation method of butanediol bis(propionitrile) ether. The preparation method comprises the following step of: reacting 1,4-butanediol and acrylonitrile serving as reaction raw materials under the catalysis of a catalyst aqueous solution at specific temperature to generate butanediol bis(propionitrile) ether, wherein the catalyst is at least one of oxide, hydroxide, carbonate and bicarbonate of alkali metal or oxide, hydroxide, carbonate and bicarbonate of alkaline earth metal, and the specific temperature is -10-70 DEG C. The preparation method of butanediol bis(propionitrile) ether has the advantages that the process is simple, no wastes are generated, the molar yield is more than or equal to 90%, the preparation process has low requirement on temperature, and thus the preparation cost is greatly lowered.

- SYNTHESIS AND TRANSFORMATION OF OXYGEN-CONTAINING MONO- AND DINITRILES. I. REACTION OF β-CHLOROPROPIONITRILES WITH DIOLS
-
In the reaction of β-chloropropionitrile with diols 7-11-membered oxygen-containing mono- and dinitriles were synthesized in ratios of 3:2 respectively, irrespective of the ratio of the initial components.Alkaline hydrolysis of oxygen-containing mononitriles with a weak solution of hydrogen peroxide leads to the formation of the corresponding amides, while alkaline hydrolysis of the oxygen-containing dinitriles leads to two products (amidonitriles and diamides).
