Abstract: PROBLEM TO BE SOLVED: To provide a catalyst for a side chain alkylation in which activity and selectivity are high and service life is long. SOLUTION: The catalyst may be doped by a compound of at least one kind of alkali metals and/or alkaline earth metals and contains at least one kind of alkali metal applied onto a spinel compound or an inverse-spinel compound used as a carrier. Weight proportion of alkali metals to the carrier is 0.01:5. When a doping agent exists, weight proportion of the doping agent to the carrier is 0.01:5.

Abstract: PROBLEM TO BE SOLVED: To manufacture a highly active catalyst which does not produce a large amount of solid content and requires a simple catalytic process by causing a chemical reaction between an aqueous metallic salt solution and an aqueous cyanomethallic acid solution, both of which are expressed by specific formulae respectively. SOLUTION: An aqueous water-soluble metallic salt solution is expressed by formula I in which M1 is the metallic ion of either of Zn , Fe , CO or Ni2+ , X is the anion of halide or hydroxide and m, n are integers corresponding to the atomic values of M1 and X. An aqueous cyanometallic acid solution is expressed by formula II in which M2 in the metallic ion of either of Fe2+ , Fe3+ , CO , Cr3+ , Rh3+ , Ni or CO , H is hydrogen, A is the anion of halide or hydroxide, and a, b, c are the integers selected so that cyanide is electrically neutralized. These aqueous solutions are caused to chemically react with each other, and further, the reaction product is caused to undergo a chemical reaction with a ligand which can be mixed with water, if necessary and contains a heteroatom. Thus a polymetallic cyanide complex produced consequently is separated from the suspension.

Abstract: Unsaturated nitriles are obtained by dehydration of corresponding unsaturated aldoximes at relatively low temperature in the gas or liquid phase over a heterogeneous basic oxide or hydroxide catalyst, optionally on an inert support. A process for the production of unsaturated nitriles of formula R-C(R )=C(R )-(CH2)n-CN (I) comprises dehydration of oximes R-C(R )=C(R )-(CH2)n-CH=N-OH (II) in the gas or liquid phase at 150-300 degrees C over a heterogeneous catalyst consisting of an oxide, nitride or carbide support doped with basic oxides and/or hydroxides or with compounds which are converted into these under the reaction conditions, or a catalyst consisting of the basic oxide alone. In (I), R, R , R = 1-20C alkyl or alkenyl or 3-12C cycloalkyl or cycloalkenyl, or two of these groups may form parts of an optionally unsaturated ring; R and R may also = H; and n = 0 or 1-20.

Abstract: The invention relates to a method for producing polyether alcohols by catalytically attaching ethylene oxide and propylene oxide to H-functional starting substances. Said method is characterized in that at least one multimetal cyanide compound is used as a catalyst, and a block comprised of an alkylene oxide having at least three carbon atoms in the molecule is attached to the chain end.

Abstract: A process for the production of alkylene glycol(s) by reaction of a mixture of alkylene oxide(s), catalyst(s) and water uses a catalyst which is insoluble in the reaction mixture and contains at least one covalently bonded acid functional group and at least one covalently bonded basic functional group. An Independent claim is also included for molded bodies containing a support with at least one acid and at least one basic functional group, these functional groups being covalently bonded with the support.
