Joseph A. Cowfer - Avon Lake OH, US

Assignee:

Oxy Vinyls, LP - Dallas TX

International Classification:

B01J 21/08
C03C 10/10

US Classification:

502240, 502243, 502244, 501 6

Abstract:

Oxychlorination catalyst compositions which include a catalytically effective amount of an oxychlorination catalyst and a diluent having certain chemical composition and/or physical properties are disclosed. Processes using such oxychlorination catalyst compositions are also described. Some oxychlorination catalyst compositions and processes disclosed herein can increase the optimal operating temperature, and thereby increase the production capacity of an existing reactor, such as a fluid-bed reactor, compared to other oxychlorination catalyst compositions.

Filed:

Jun 16, 1999

Appl. No.:

9/242093

Inventors:

Roy G. Gordon - Cambridge MA
Keith Kramer - Avon Lake OH
Haifan Liang - Santa Clara CA

Assignee:

President and Fellows of Harvard College - Cambridge MA

International Classification:

C23C 1640

US Classification:

42725533

Abstract:

Fims of fluorine-doped zinc oxide are deposited from vaporized precursor compounds comprising a chelate of a dialkylzinc, such as an amine chelate, an oxygen source, and a fluorine source. The coatings are highly electrically conductive, transparent to visible light, reflective to infrared radiation, absorbing to ultraviolet light, and free of carbon impurity.

C07C 17/10

Abstract:

A method of producing carbon tetrachloride, the method comprising the step of reacting chlorine with chloroform in the presence of electromagnetic radiation within a reaction mixture that includes the chlorine, the chloroform, and carbon tetrachloride, where the concentration of chloroform is less than 5000 ppm by weight relative to the weight of the reaction mixture, where the reaction mixture includes at least stoichiometric levels of chlorine relative to chloroform, where the electromagnetic radiation creates chloride radicals, and where the reaction mixture is well mixed.
