Patent Number: US 8273907
Title: Process for producing propylene oxide using titanosilicate epoxidation catalyst system
Inventor(s): Kawabata, Tomonori; Abekawa, Hiroaki
Patent Assignee(s): Sumitomo Chemical Company, Limited, Japan

Language: Japanese

Abstract:
A process for more efficiently producing propylene oxide from propylene, oxygen, and hydrogen with catalysts which comprise a noble metal and a titanosilicate having pores not smaller than a 12-membered oxygen ring. The process for propylene oxide production is characterized by reacting propylene, oxygen, and hydrogen in a solution comprising water, a nitrile compound, and an ammonium salt in the presence of a noble metal catalyst and a titanosilicate catalyst having pores not smaller than a 12-membered oxygen ring.

Please note:  Titles and abstracts for patent records in CAplus are routinely enhanced to better describe the claimed invention. In this example, CAS enhanced both the abstract and title using additional information found in the patent. The original title of the publication is Process for producing propylene oxide. For the CAplus record, this title was enhanced to read Process for producing propylene oxide using titanosilicate epoxidation catalyst system.
