| 20080220967 | ALUMINUM PHOSPHATE-SUPPORTED GROUP 6 METAL AMIDE CATALYSTS FOR OLIGOMERIZATION OF ETHYLENE - A catalyst composition for the preparation of oligomeric and/or polymer derivatives of olefin monomers, said composition comprising a Group 6 metal amide complex, a Group 1, 2, 12, 13, or 14 metal hydrocarbyl composition or compound, and a solid support comprising aluminum phosphate. | 09-11-2008 |
| 20090186985 | Functionalized elastomer compositions - The present invention relates to olefinic compositions comprising a functionalized branched olefin copolymer containing functionalized sidechains derived from olefin and at least one chain end nucleophilic heteroatom containing functional group with at least one protic hydrogen, optionally with one or more copolymerizable monomers, the copolymer characterized by having A) a T | 07-23-2009 |
| 20090312450 | POLYURETHANES MADE FROM HYDROXYL-CONTAINING FATTY ACID AMIDES - Polyurethanes, and rigid polyurethane foams in particular, are made using certain amides of modified fatty acids. The fatty acid groups are substituted hydroxymethyl, N-hydroxyalkyl aminoalkyl or hydroxy-substituted ester groups. The amide portion of the molecule contains hydroxyalkyl or other hydroxyl-substituted organic groups bonded to the amide nitrogen. | 12-17-2009 |
| 20100048940 | POLYOL 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 |
| 20100152499 | CONVERSION OF A MULTIHYDROXYLATED-ALIPHATIC HYDROCARBON OR ESTER THEREOF TO A CHLOROHYDRIN - The present invention relates to a process for converting at least one multihydroxylated-aliphatic hydrocarbon and/or an ester thereof to at least one chlorohydrin and/or an ester thereof, comprising at least one reaction step in which the multihydroxylated-aliphatic hydrocarbon and/or ester thereof is contacted with hydrogen chloride under reaction conditions to produce the chlorohydrin and/or ester thereof, followed by at least one downstream processing step in which the effluents of the reaction step are processed, wherein the downstream processing step is performed in such conditions that the effluents containing the chlorohydrin and/or ester thereof are kept at a temperature of less than 12O° C. The invention allows to minimize the liberation of hydrogen chloride from the products of the hydrochlorination reaction, hence reducing the corrosion of the downstream equipment and reducing M the need to use costly corrosion resistant materials. | 06-17-2010 |
| 20100168352 | PRODUCTION OF TELECHELIC COMPOUNDS BY METATHESIS DEPOLYMERIZATION - Telechelic unsaturated polymers suitable for conversion to functionalized derivatives such as polyols are prepared by metathesis of an unsaturated copolymer formed by addition polymerization of ethylene, a diene or alkyne and, optionally, one or more C | 07-01-2010 |
| 20110004027 | PROCESS AND APPARATUS FOR PRODUCING CHLOROHYDRIN - A process and apparatus for producing chlorohydrin comprising reacting a multihydroxylated-aliphatic hydrocarbon-containing stream with a stream of a first effluent exiting from a hydrochlorination reactor in at least one vessel wherein the vessel exhibits a plug flow residence time characteristic, under conditions such that at least a portion of any unreacted HCl component present in the first effluent is reacted with the multihydroxylated-aliphatic hydrocarbon present in the multihydroxylated aliphatic hydrogen-containing stream to from an amount of monochlorohydrin in a stream of a second effluent exiting from the plug flow vessel; recovering said second effluent; and then optionally using the second effluent from the plug flow reactor in a subsequent processing operation. | 01-06-2011 |
| 20110028766 | CONVERSION OF A MULTIHYDROXYLATED-ALIPHATIC HYDROCARBON OR ESTER THEREOF TO A CHLOROHYDRIN - The present invention relates to a process for converting at least one multihydroxylated-aliphatic hydrocarbon and/or an ester thereof to at least one chlorohydrin and/or an ester thereof, comprising at least one reaction step in which the multihydroxylated-aliphatic hydrocarbon and/or ester thereof is contacted with hydrogen chloride under reaction conditions to produce the chlorohydrin and/or ester thereof, followed by at least one downstream processing step in which the effluents of the reaction step are processed, wherein the downstream processing step is performed in such conditions that the effluents containing the chlorohydrin and/or ester thereof are kept at a temperature of less than 120° C. The invention allows to minimize the liberation of hydrogen chloride from the products of the hydrochlorination reaction, hence reducing the corrosion of the downstream equipment and reducing the need to use costly corrosion resistant materials. | 02-03-2011 |
| 20110137086 | PROCESS FOR TELOMERIZATION OF BUTADIENE - In an improved process for telomerizing butadiene, contact butadiene and an organic hydroxy compound represented by formula ROH (I), wherein R is a substituted or unsubstituted C | 06-09-2011 |
