摘要:
4-SUBSTITUTED-5,7-DINITRO -2- (A,A-DIFLUOROALKYL)BENZIMIDAZOLE COMPOUNDS AND THEIR ALKALI METAL AND ALKALINE ERTH MTAL SALTS, USEFUL AS INSECTICIDES.
摘要:
1- (BUTYLCARBAMOYL) - 2 (METHYLAMINO)-BENZIMIDAZOLIUM SALTS ARE PREPARED BY HEATING METHYL 1- (BUTYLCARBAMOYL) - 2 BENZIMIDAZOLECARBAMATE AND AN ORGANIC ACID HAVING FROM1 TO ABOUT 6 CARBON ATOMS, SUCH AS LACTIC ACID, IN A POLAR SOLVENT, SUCH AS DIMETHYL SULFOXIDE, TO A TEMPERATURE BETWEEN ABOUT 175 ABD 315 DEGREES F. THE BENZIMIDAZOLIUM SALTS ARE EFFECTIVE IN THE CONTROL OF CERTAIN PLANT FUNGUS DISEASE.
摘要:
2-ARYLBENZAZOLES, I.E. 2-ARYLBENZIMIDAZOLES, 2-ARYLBENZOXAZOLEES AND 2-ARYLBENZTHIAZOLES, AE PREPARED BY THE CONDENSATION OF AN AROMATIC ALDEHYDE BISULFITE ADDUCT WITH O-PHENYLENEDIAMINE, O-AMINOPHENOL AND O-THIOPHENOL, RESPECTIVELY. POLYBENZIMIDAZOLES, KNOWN POLYMERS PARTICULARLY USEFUL IN THE FABRICATION OF ARTICLES INTENTED FOR USE AT ELEVATED TEMPERATURES, ARE PREPARED BY THE CONDENSATION OF AROMATIC TETRAAMINES WITH AROMATIC DIALDEHYDE BISBISULFITE ADDUCTS.
