| titleOfInvention | Method for synthesizing triisobutyl phosphine sulfide |
| abstract | The invention discloses a method for synthesizing triisobutyl phosphine sulfide. The method comprises the following steps of: reacting by taking nitrogen as protective gas, benzene as a solvent, and 1-bromo-2-methylpropane, magnesium and phosphorus trichloride as substrates at the temperature of between 50 and 80DEG C for 1 to 3 hours, and synthesizing an intermediate product of triisobutyl phosphine; and reacting the intermediate product of triisobutyl phosphine with sulfur at the temperature of between 50 and 80DEG C for 2 to 4 hours to obtain the target product of triisobutyl phosphine sulfide. The total yield of the method can reach 50.31 percent, the reaction time is short, the reaction conditions are mild, a reaction system is safe to operate, and the method is suitable for industrial promotion and application. |
