Abstract

Propylene-oxide is produced from a mixture of propylene, oxygen, and a diluent at a temperature above 200 DEG C. by contact with silver containing small quantities of gold and/or copper. The temperature may be 300--375 DEG C. In examples: (1) propylene, air, and carbon dioxide are employed, the propylene oxide being absorbed in active carbon or dissolved in water; (2) the same process is effected at 50 atmospheres pressure; (4) propylene, air, and steam are employed; (5) colloidal, silver containing a small proportion of gold and/or copper is placed in a high pressure tube full of water, propylene being pumped in to dissolve in the water; the tube is then heated to 300--375 DEG C. and air is forced in. Specification 397,161 is referred to. The Specification as open to inspection under Sect. 91 includes the use of silver as the catalyst. This subject-matter does not appear in the Specification as accepted.
