Patent CA-2654427-C (CA)
Inventor: WANG FAN
IPC: C07D401/12
Filed: 2007-06-08
Granted: 2014-08-19
Abstract: A novel process for the preparation of omeprazole and its enantiomers, such as esomeprazole, as well as the preparation of related 2-(2-pyridinylmethyl-sulphinyl)-1H-benzimidazoles, including pantoprazole, lansoprazole and rabeprazole, as recemates or single enantiomers, and their alkali or alkaline salts has been developed. The novel process involves the surprising discovery that protection of the free-base benzimidazole sulfoxide (e.g. omeprazole or esomeprazole), by reaction with an alkyl, aryl or aralkyl chloroformate following oxidation of the corresponding sulfide, eliminates the need for its direct isolation. Subsequent removal of the protecting group with a solution of alkali or alkaline earth alkoxide in a C1-C4 alcohol directly provides the corresponding salt. By eliminating the need to handle the free-base benzimidazole sulfoxide, this advantageous procedure provides increased chemical yields over processes described in the art.

Abstract: It is difficult to appropriate estimate the colorimetric values of an arbitrary patch at a desired temperature with respect to an arbitrary medium in consideration of the influence of a fluorescent whitening agent contained in the medium. Target patch colorimetric values obtained when patches of a plurality of colors formed on a medium using color samples are measured at a target temperature designated in step S101. This estimation is implemented when both media-dependent variation correction processing (S102) that estimates patch colorimetric values based on the temperature characteristics of the medium, and toner-dependent variation correction processing (S103) that estimates patch colorimetric values based on the temperature characteristics of the color samples are executed.    By correcting image data whose image is to be formed based on the target patch colorimetric values (S104), an arbitrary color patch on an arbitrary medium can be coped with.

Abstract: Redispersible polymer powder compositions which include a polyglycol in admixture with a redispersible polymer powder (RDP), which powder includes a codried mixture of a carboxylated, water insoluble film-forming styrene butadiene polymer and a colloidal stabilizer, results in cement compositions having unexpectedly superior overall bonding strength and adhesion after water immersion. Use of the polyglycol provides good workability or ease of troweling during application. In addition, the RDP composition, which includes the RDP and the polyglycol, provides the cement-based composition with excellent abrasion resistance, surface appearance, and color. Also, the RDP composition provides for at least a 30% reduction, for example a 50% or more reduction in the amount of retarder or retardant employed in the dry mix formulation for cement compositions, such as self leveling flooring compounds or compositions, and cement-based tile adhesives.
