标 题 :Polymerization of olefins
发明人：BROOKHART MAURICE S; JOHNSON LYNDA KAYE; KILLIAN CHRISTOPHER MOORE
权利人:DU PONT
摘要:Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear α-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected α-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected α-diimine nickel complexes with ethylene.

标 题:Process for synthesizing a heteropoly acid catalyst for oxidation of unsaturated aldehydes to unsaturated carboxylic acid
发明人：KAUFFMAN JAMES W; CAI LIXIA; LIANG WUGENG
权利人:SAUDI BASIC IND CORP
摘要:The present invention is for a process for making a heteropoly acid compound catalyst for oxidation of unsaturated aldehydes, such as methacrolein, to unsaturated carboxylic acids, such as methacrylic acid, said catalyst containing oxides of molybdenum, phosphorus, and M′, wherein M′ is cesium, potassium, rubidium, or sodium, and bismuth. The process is a synthesis of the catalyst with specific process conditions for addition of the bismuth compound as an aqueous slurry without nitric acid. A catalyst precursor is formed by removing the water and drying the solid particles. The heteropoly acid compound catalyst is formed by calcination of the catalyst precursor.

权利人:RHONE POULENC CHIMIE
摘要:The alkyl hydroquinones, e.g., methyl hydroquinone (a useful intermediate in the preparation of the monomer methyl hydroquinone diacetate, itself used for the synthesis of thermotropic polymers), are prepared by reacting (C-alkylating) hydroquinone or a monoether thereof with a lower alkanal, in the vapor phase, with a catalytically effective amount of at least one solid metal oxide.

发明人：Iacono Pasquale; HLAVINKA MARK L
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a metal-treated chemically-modified solid oxide such as a sulfur oxoacid anion-modified solid oxide, a phosphorus oxoacid anion-modified solid oxide, or a halide ion-modified solid oxide, to provide a reaction mixture; and (2) applying reaction conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or the salt thereof. Methods of regenerating the metal-treated chemically-modified solid oxide are described.

标题 :Method for producing a catalyst for unsaturated carboxylic acid synthesis
发明人：ABE YOSHIMUNE; KANUKA NARIYASU; OKADA SHIGEKI
权利人:MITSUBISHI CHEM CORP
摘要:A method for producing a catalyst for unsaturated carboxylic acid synthesis is proposed. The method includes: obtaining a dried product by drying and heat-treating a starting material mixed liquid in which supply source compounds of respective catalyst component elements are integrated; and forming a catalyst precursor by supporting powder to be supported on a carrier in the form of a particle aggregate. The powder to be supported is either the dried product or obtained from the dried product. The method further includes calcining the catalyst precursor to form the catalyst. The mass loss rate of the powder to be supported at 300° C. is less than 5 percent by mass, and the difference between the mass loss rate of the powder at 370° C. and the mass loss rate of the powder at 300° C. is not less than 1 percent by mass and not more than 6 percent by mass.
