| titleOfInvention | Method for producing primary phosphine |
| abstract | PROBLEM TO BE SOLVED: To provide a method for selectively producing primary phosphine with a high yield. SOLUTION: In the method for producing a primary phosphine by reacting a phosphine and an alkyl halide in an alkaline aqueous solution and an organic solvent in the presence of a catalyst, R 1 Br (R is a carbon number of 3 to 3) is used as the alkyl halide. 8 represents a linear or branched alkyl group, cycloalkyl group, benzyl group or allyl group), using a tetraalkylphosphonium bromide as a catalyst to obtain a phosphine for the alkyl bromide. The reaction is carried out at a temperature of 60 ° C. or more by introducing the required amount of catalyst into the reaction system by dividing it into several steps or adjusting the addition rate continuously. method for producing a primary phosphine represented by 1 PH 2. |
