in which R1 and R2 are substituted or unsubstituted alkyl or alkenyl, and R3 is haloalkyl-phenyl, haloalkoxy-phenyl, haloalkylthio-phenyl or halovinyloxy-phenyl or carbomethoxythienyl, are valuable herbicides.
Abstract:
Substituted benzimidazoles of the formula
IN WHICH R1 is alkyl, X is oxygen or sulfur, R2 is haloalkyl or haloalkenyl and R3, R4 and R5 each are hydrogen, halogen or alkyl, are valuable as systemic fungicides and as anthelmintic agents.
Abstract:
- 8 - HOE 90/F 366 Process for the preparation of calcium sulfonate/calcium carbonate complexes In the process for the preparation of superbasic calcium sulfonate/calcium carbonate complexes, a mixture of - oil-soluble aralkylsulfonic acids, - calcium oxide and/or calcium hydroxide and - carboxylic acids, is reacted in the presence of a liquid non-polar reaction medium, water-soluble polar solubilizing agents and water. The reaction with carbon dioxide is then carried out. Water-immiscible or water-insoluble carboxylic acids are employed as the carboxylic acids. The process products are used as anticorrosive agents.
Abstract:
A process for the continuous production of C7-Cl2-acyloxybenzenesulfonic acids, wherein phenol and a sulfonating reagent, diluted with an aliphatic C7-Cl2-carboxylic acid, is charged to the top of a continuous-flow reactor heated to 80 DEG -100 DEG and the mixture of phenolsulfonic acid and the aliphatic carboxylic acid, leaving the bottom end of this continuous-flow reactor, and a chlorinating reagent are charged to the top of a second continuous-flow reactor, nitrogen being passed in counter-current through both continuous-flow reactors.
Abstract:
of the disclosure Compounds of the formula I wherein one of R1 and/or R3 are substituted carbamoyl and the other is preferably hydrogen or methyl, R2 is a variety of substituents among which is hydrogen and acetyl, and R3 and R4 preferably form together a saturated or unsaturated C4-chain which may be substituted, are valuable aphicides.
