30 g of yellow phosphorus, an inert dispersion aid of Shokou, and 500 g of water were introduced, and nitrogen gas was introduced from the nitrogen gas introduction pipe.
The air in the reaction vessel was expelled, and yellow phosphorus was dispersed in fine particles by heating to 70 to 75°C and stirring. Next, 102.4 g of a 25% aqueous sodium hydroxide solution was added to this dispersion.
According to the progress of the 0 reaction, which was reacted by dropping over a period of time,
Good generation of phosphine was observed along with the generation of sodium hypophosphite.
The reaction was completed by heating and stirring for 5 minutes, and the generated phosphine was collected to obtain 10.51 vol. of gas containing 52.6 vol.% of phosphine on average. This phosphine yield corresponds to 94.9%. Since the phosphine gas obtained in this manner contains a large amount of water, it was dehumidified by passing through an activated carbon column and then inserted into a cylinder to obtain phosphine as a raw material.
