20090078910FUNCTIONALIZED LONG-CHAIN OLEFIN MIXTURES AND USES THEREFOR - Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.03-26-2009
20090247744HYDROFORMYLATION PROCESS FOR PHARMACEUTICAL INTERMEDIATE - The invention relates to an improved process for the preparation of an advanced synthetic intermediate of ACE inhibitors. In one aspect, the present invention is based on a novel process for the preparation of an aldehyde of formula (I), wherein (N)10-01-2009
20090281359PROCESS FOR OLEFIN ETHERIFICATION - The invention relates to processes for the etherification of olefins with alcohols. According to one aspect, a heterogeneous etherification catalyst is used under conditions that permit limiting the contact time between the desired product and the catalyst, thereby mitigation reverse reactions. According to a second aspect, a recycling process is used that significantly increases the yield of desired product.11-12-2009
20100048940POLYOL ETHERS AND PROCESS FOR MAKING THEM - New polyol ether compounds and a process for their preparation. The process comprises reacting a polyol, a carbonyl compound, and hydrogen in the presence of hydrogenation catalyst, to provide the polyol ether. The molar ratio of polyol to carbonyl compound in the process is greater than 5:1.02-25-2010
20100267844ALKYLENE OXIDE-CAPPED SECONDARY ALCOHOL ALKOXYLATES USEFUL AS SURFACTANTS - Disclosed are compositions of the formula wherein R10-21-2010
20100286277METHOD TO ENHANCE AQUEOUS SOLUBILITY OF POORLY SOLUBLE ACTIVES - A method to enhance solubility of an active compound comprises combining an active compound, having an aqueous solubility that is less than or equal to about 10 mg/mL, and an amount of methoxypolyethylene glycol that is sufficient to increase the aqueous solubility of the active compound. Enhancement of aqueous solubility for this combination may be significantly greater than that of an active compound in combination with an equivalent amount of polyethylene glycol. Particularly enhanced solubility is shown where a small amount of water is also included. The invention may be used in a wide variety of applications, such as for pharmaceutical, agricultural, antimicrobial, and personal care products.11-11-2010
