Abstract:
There is disclosed a number of processes for the promotion of the Raney Nickel catalyzed hydrogenation of carbon-carbon double bonds. (a) One process uses tertiary amines to promote the Raney Nickel catalyzed hydrogenation. (b) Another process uses acetylene and acetylene derivatives to promote the Raney Nickel catalyzed hydrogenation. The promotion of Raney Nickel catalyst is particularly suited for the reduction of unsaturated hydantoins to saturated hydantoins and also for the reduction of cyclic and acyclic olefins and diolefins to the corresponding cyclic and acyclic alkanes.
Abstract:
Compounds and compositions containing them, for insecticidal control, particularly for use as soil and/or foliar insecticides, have the formula in which R 1 is C 1 -C 3 alkyl; R 2 is C 1 -C 6 alkyl or C 5 -C 6 cycloalkyl; R 3 is hydrogen or C 1 -C 3 alkyl; R 4 is hydrogen, C 1 -C 4 alkyl, phenyl, halogen or halo-(C 1 -C 4 alkyl); and R 5 and R 6 are independently hydrogen, halogen, C 1 -C 4 alkyl, phenyl, or C 2 -C 5 carboalkoxy; or R 3 and R 5 taken together form a trimethylene group; provided that if R 3 , R 5 and R 6 are all hydrogen, R 4 is not hydrogen; together with insecticidal compositions containing such compounds, and methods for controlling insects.
Abstract:
Novel trisubstituted benzoic acid intermediates which are useful in the preparation of certain herbicidal 2-(2,3,4- trisubstituted benzoyl)-1,3-cyclohexanediones. The intermediate benzoic acids of this invention have the following structural formula: wherein R 6 is chlorine, C 1 -C 4 alkoxy, C 1 -C 4 alkylthio or hydroxy; n is the integer 0 or 2; and R 7 is C 1 -C 4 alkyl.
Abstract:
An electric contact lubricant is disclosed which comprises a predominant amount of an evaporable solvent and a lubricant which, in turn, comprises a predominant amount of a partially crosslinked polyol ester formed by esterification of an aliphatic mono-carboxylic acid with an aliphatic polyol in the presence of a dibasic acid crosslinker, a lesser amount of a phosphate ester fluid, and one or more corrosion and oxidation inhibitor compounds.
