An imidazole compound is disclosed, which is represented by formula (I): ##STR1## wherein: X represents a --COOT group, in which T represents a hydrogen atom, an alkyl group, a benzyl group, or a phenyl group; or a --CONH.sub.2 group,

Imidazole compound and process for preparing the same

Novel imidazole compounds are disclosed, which are represented by the following general formula: ##STR1## wherein: R.sub.1 represents a cyano group or a --CSNHR.sub.5 group, wherein R.sub.5 represents a hydrogen atom, a C.sub.1-4 alkyl group, or a --COR.sub.6 group, wherein R.sub.6 represents a C.sub.1-4 alkyl group, a halogenated C.sub.1-4 alkyl group, or a phenyl group;

Imidazole compounds and biocidal composition comprising the same for

A biocidal composition containing, as active ingredients, at least one imidazole compound represented by formula (I): ##STR1## wherein R.sup.1 represents a phenyl group, a halogen-substituted phenyl group, an alkyl group, or a halogen-substituted alkyl group; and R.sup.2 represents a halogen atom, and at least one other specific compound. The combination of the compound represented by formula (I) and other specific compound can produce an unexpected effect in amount required and biocidal spectrum.

Biocidal composition

A chloronicotinic acid compound is prepared by hydrolyzing a 3-trichloromethyl pyridine compound in the presence of sulfuric acid or phosphoric acid. By this process, a highly pure chloronicotinic acid compound is obtainable in good yield. This compound is useful as an intermediate for medicines.

Process for producing chloronicotinic acid compounds

5,6-Dichloro-.beta.-trifluoromethylpyridine or 2,5,6-trichloro-.beta.-trifluoromethylpyridine is produced by reacting 6-chloro-.beta.-trifluoromethylpyridine or 2,6-dichloro-.beta.-trifluoromethylpyridine with chlorine gas to chlorinate the 5-position of pyridine nucleus thereof:

Process for producing 5-chloro-.beta.-trifluoromethylpyridines

4-Benzoyl-5-hydroxypyrazoles useful as herbicidal active ingredients, their intermediate or stabilizers against heat, oxidation or ultraviolet light are produced by a condensation of a pyrazolone, tetrachloromethane and a benzene compound in the presence of an aluminium halide, followed by a hydrolysis reaction with industrial advantages.

Process for producing 4-benzoylpyrazoles

A phenoxybutyltriazole compound represented by the following formula (I): ##STR1## wherein X is a halogen atom, a phenyl group or a 5-trifluoromethylpyridine-2-yloxy group; Y is a halogen atom or a trifluoromethyl group; Q is a &gt;C.dbd.O group or a &gt;CH--OH group; A is a &gt;CH-- group or a nitrogen atom; and m and n are each an integer of 0 to 2, or a salt thereof, which is useful as an active ingredient for agricultural and horticultural fungicides, is disclosed. A process for producing the compound of the formula (I) is also disclosed.

Phenoxybutyltriazole compound, agricultural and horticultural fungicidal

4-Benzoyl-5-hydroxypyrazoles useful as herbicidal active ingredients or their intermediate are produced by a condensation of a pyrazolone and a benzotrichloride followed by a hydrolysis reaction with industrial advantages.

A novel compound, 2-amino-trifluoromethyl-halogenopyridine, is provided, which is prepared by amination of a 2-halogeno-trifluoromethyl-halogenopyridine or by halogenation of 2-amino-trifluoromethylpyridine. This compound is useful as an intermediate for synthesis of agricultural chemicals and medicines.
