Process For Preparing High Cyclic Phosphonitrilic Halides
US Patent:
4196179, Apr 1, 1980
Filed:
Jul 3, 1975
Appl. No.:
5/592875
Inventors:
John W. Hudson - Baton Rouge LA
Thomas F. Dominick - Baton Rouge LA
Thomas F. Dominick - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C01B 2510
US Classification:
423300
Abstract:
Preparation of high cyclic phosphonitrilic halide, preferably chloride, oligomer mixtures by reaction of phosphorus trichloride, chlorine and ammonia at temperatures from 65. degree. to 180. degree. C. in which the reactants are simultaneously fed to an agitated inert solvent at a rate such that the phosphorus trichloride concentration is at most stoichiometric relative to the chlorine and ammonia concentration and such that petroleum ether insoluble phosphonitrilic chloride formation is suppressed, and recovering the cyclic phosphonitrilic halide oligomer mixture without extracting petroleum ether insoluble materials since these are not produced.
Accelerator Compositions And Rubber Compounding Composition Embodying The Same
US Patent:
5354793, Oct 11, 1994
Filed:
Dec 20, 1991
Appl. No.:
7/811246
Inventors:
John C. Hudson - Baton Rouge LA
Assignee:
DSM Copolymer, Inc. - Baton Rouge LA
International Classification:
C08K 535
US Classification:
524 96
Abstract:
An accelerator composition and a rubber compounding composition in which a rubber is blended with a combination of three accelerators and sulfur for curing the rubber while minimizing the formation of iridescent sheen. The combination of accelerators included a thiolated morpholine, a dithiocarbamate and a benzothiazole.
