To provide an aldehyde scavenger and a method for removing aldehydes by using the same, for quickly and continuously capturing aldehydes. An aldehyde scavenger comprising at least one O-substituted hydroxylamine or at least one chemically acceptable salt thereof, is used against an aldehyde generation source.

Aldehyde scavenger and method for removing aldehydes

Provided are a polycyclic pyrazolinone derivative indicated by general formula (1) (in the formula, R, X, X, X, and Y indicate the definitions provided in the Specification) and a herbicide comprising same as effective component thereof. 

Polycyclic pyrazolinone derivative and herbicide comprising same as effective component thereof

In a process for producing 1-substituted-3-fluoroalkyl-pyrazole-4-carboxylate (3) by a reaction of 2-alkoxymethylenefluoroacylacetate (1) and hydrazine (2), the reaction is conducted in the presence of a base and water, to produce 1-substituted-3-fluoroalkylpyrazole-4-carboxylate (3) with high selectivity and yield. This novel process enables to produce 1-substituted-3-fluoroalkylpyrazole-4-carboxylate (3), which is useful as an intermediate for pharmaceuticals and agrochemicals, with high selectivity and yield by simple and safe operations.

Process for producing 1-substituted-3-fluoroalkylpyrazole-4-carboxylate

Disclosed are pyrazole-1-carboxylate derivatives of the general formula (1),  According to this invention, there can be industrially advantageously produced 3-aryloxypyrazole-1-carboxamide derivatives that does not cause chemical damage on crops but exhibits excellent herbicidal activity against weeds that impair the growth of such crops.

Pyrazole-1-carboxylate derivatives, process for the production thereof and process for the production of pyrazole derivatives

The present invention provides a pyrazole derivative of the general formula (1), which has an excellent efficacy as an active component for a herbicide, an intermediate for the production thereof, processes for the production thereof, and a herbicide containing the derivative as an active ingredient.

The present invention relates to 3,4,5,6-tetrahydrophthalamide derivatives and 3,4,5,6-tetrahydroisophthalimide derivatives having excellent effects as effective active ingredients of herbicides, and processes for preparing the same, and provides the compounds having a more efficient herbicidal activity, and efficient and industrial processes for the preparation thereof. More specifically, the tetrahydrophthalimide derivative obtained by reacting a halogen-substituted 5-cycloalkyloxyaniline derivative with a 3,4,5,6-tetrahydrophthalic anhydride, or the tetrahydroisophthalimide derivative of the present invention is reacted with various types of amines to prepare a tetrahydrophthalamide derivative represented by the general formula (I): ##STR1## These tetrahydrophthalamide derivatives and the tetrahydroisophthalimide derivatives exhibit excellent herbicidal activities in the soil treatment in the paddy field and field and the stem-foliar treatment. The tetrahydroisophthalimide derivatives are also useful as intermediates for the preparation of the tetrahydrophthalamide derivatives, etc.

Tetrahydrophthalamide derivative, intermediate for producing the same,

A benzene derivative substituted with a heterocyclic ring represented by the general formula: ##STR1## wherein R represents a cycloalkyl group having 3 to 8 carbon atoms, X represents a halogen atom, and Z represents ##STR2## in which said cycloalkyl group may be substituted with an alkyl group having 1 to 6 carbon atoms, a process for preparing the same, and a herbicidal agent comprising the above compound as an active ingredient are disclosed. The compound has an excellent effect in that the compound exhibits a markedly high herbicidal effect on weeds in the field and the paddy field at a low dose and yet exhibits markedly low noxious effects on main crops.
