Patent number: 6211383Abstract: A reaction for eliminating a functional group alpha to a carbonyl group. The reaction can be used to dehydrate a compound having an alcohol group alpha to a carbonyl group by reacting the compound in a non-aqueous non-polar solvent in the presence of an effective amount of a transition metal salt, such as zinc chloride, such that the alcohol group is dehydrated. This Nohr-MacDonald Elimination Reaction produces a light stable compound, which can be added to compositions for light stabilization of a colorant.

Patent number: 6210516Abstract: Permanent surface modification of polypropylene nonwoven fabrics is achieved through electron beam radiation induced chemical bonding. The electron beam energy levels suitable for such chemical bonding are between about 5 KeV to about 110 KeV at the surface of the fabric facing the electron beam radiation source. At these energy levels, chemical bonding, control of electron beam penetration and the formation of free radicals in the polypropylene nonwoven fabrics are achieved. Control of electron beam penetration produces free radical formation and chemical bonding at selective levels within the fabric as well as bonding of different chemicals asymmetrically to the same fabric with minimal, if any, loss of polymer fabric strength.Type: GrantFiled: October 6, 1997Date of Patent: April 3, 2001Inventors: Ronald Sinclair Nohr, John Gavin MacDonald

Patent number: 6090236Abstract: A method of generating reactive species which includes exposing a polymolecular photoreactor to radiation, in which the polymolecular photoreactor comprises a wavelength-specific sensitizer associated with a reactive species-generating photoinitiator. The sensitizer absorbs energy and transfers the absorbed energy to the photoinitiator which in turn, generates reactive species. The wavelength-specific sensitizer is adapted to have an absorption wavelength band generally corresponding to an emission peak of the radiation. The radiation to which the polymolecular photoreactor is exposed generally will have a wavelength of from about 4 to about 1,000 nanometers. Thus, the radiation may be ultraviolet radiation, including near ultraviolet and far or vacuum ultraviolet radiation: visible radiation: and near infrared radiation. Desirably, the radiation will have a wavelength of from about 100 to about 900 nanometers.Type: GrantFiled: December 31, 1997Date of Patent: July 18, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ronald Sinclair Nohr, John Gavin MacDonald
