摘要： PHOSPHORUS IS SUBSTANTIALLY COMPLETELY REMOVED FROM FERROPHOSPHORUS BY HEATING THE FERROPHOSPHORUS IN ADMIXTURE WITH AN OXIDIZING AGENT AND A NEUTRALIZING AGENT TO AT LEAST SINTERING TEMPERATURE IN A CONTAINER HAVING OXIDE REFRACTORY WALLS AND LEACHING WITH AN ALKALINE SOLUTION. THE RESIDUAL PHOSPHORUS FREE METAL VALUES HAVE RECOGNIZED UTILITY IN THE METALLURGICAL INDUSTRY AND THE PHOSPHATES ARE USEFUL IN FERTILIZER, FEED AND DETERGENT TECHNOLOGY.

摘要： Ferrophosphorus is heated in admixture and excess aluminum to convert the phosphorus therein to aluminum phosphide. The aluminum phosphide is hydrolyzed and an alloy comprising the nonphosphorus constituents of the ferrophosphorus and unreacted aluminum is separated from the hydrolysis products. The alloy of non-phosphorus constituents and aluminum is useful in the metallurgical industry and the phosphine obtained during the hydrolysis reaction has well-known utility as a chemical intermediate, for example, in preparing gasoline additives such as tributyl phosphine.
