Patent number: 6177575Abstract: Imidazoles may be manufactured by reacting a glyoxal, ammonia, an aldehyde, and optionally a primary amine, in the presence of a Bronsted acid whose pKa is approximately equal to the pKa of the ammonium cation of the primary amine, or if the primary amine is not present, to the pKa of the ammonium (NH4+) cation. The reaction may be used to make in relatively high yields a wide variety of imidazoles using relatively inexpensive starting materials. The imidazoles are useful as chemical intermediates.Type: GrantFiled: November 17, 1998Date of Patent: January 23, 2001Assignee: E. I. du Pont de Nemours and CompanyInventors: Anthony J.

Patent number: 5563275Abstract: Disclosed herein is a process for anionic polymerization of selected methacrylate monomers at elevated (as high as about 100.degree. C.) temperatures, while maintaining good "living" characteristics, by carrying out the polymerization in the presence of a silicon compound and a large cation. Also disclosed is an improved process for the polymerization of vinyl monomers, including methacrylates, which process comprises the use of an anionic intiator which is a combination of an alkali metal hydride and an alkoxysilane or a combination of an alkali metal alkoxide and a silicon hydride.Type: GrantFiled: March 7, 1995Date of Patent: October 8, 1996Assignee: E.
