ABSTRACT:
Production of phosphorus pentasulfide from phosphorus and sulfur at elevated temperature in a reactor of which the walls are in heat exchange with a substance kept at the temperature necessary for cooling or heating reaction mixture.
The heat exchange in the bottom portion of the reactor is more particularly effected with the use of a system functioning separately and independently from the heat exchange system surrounding the lateral walls of the reactor.
