Abstract
Phosphorous compounds in acetylene are oxidized to phosphoric acid and removed as such by treatment with oxygen, preferably at a raised temperature, in the presence of activated charcoal as catalyst. Acetylene mixed with a small proportion of oxygen, air, &c. is passed through a reaction tower packed with activated charcoal and heated to 80-100 DEG C.; alternatively, acetylene and air, &c. are passed in succession over the charcoal. Phosphoric acid is recovered by extracting the charcoal with hot water.ALSO:Phosphorus compounds in acetylene are oxidized to phosphoric acid and removed as such by treatment with oxygen, preferably at a raised temperature, in the presence of activated charcoal as catalyst. Acetylene mixed with a small proportion of oxygen, air, &c. is passed through a reaction tower packed with activated charcoal and heated to 80-100 DEG C.; alternatively, acetylene and air, &c. are passed in succession over the charcoal. Phosphoric acid is recovered by extracting the charcoal with hot water. The Specification as open to inspection under Sect. 91 (3) (a) states that phosphorous acid is produced in the process. This subject-matter does not appear in the Specification as accepted.
