Abstract
Apparatus and method for preparing phosphorus compounds wherein phosphorus vapor containing P.sub.2 molecules is condensed at a temperature below the solidification point of red phosphorus and the resulting solid is then reacted with a phosphorus-reactive material. When the phosphorus-reactive material is water at an elevated temperature, phosphine is produced.
