Preparation method of monolinuron

-

Paragraph 0040-0075, (2019/04/02)

The invention belongs to the field of pesticide synthesis technology, and particularly relates to a preparation method of monolinuron. A monolinuron product is prepared through a one-step reaction ina polar solvent by analyzing the structure of monolinuron and the steric hindrance of chemical synthesis, and using cheap and easily available p-chlorophenyl isocyanate and dimethylhydroxylamine hydrochloride as main raw materials. The product purity reaches 98% or more than 98%, and the product yield is close to 80%, therefore, the technical problems of complicated process, multiple by-products and environmental pollution existing in the preparation technology of monolinuron in the prior art are solved.

Herbicidal composition for upland farming and weeding method

-

, (2008/06/13)

A herbicidal composition for upland farming which can control weeds that have been difficult to control, for example, cleavers, chickweed, birdseye speedwell and violet, said composition containing as active ingredients a 3-substituted phenylpyrazole derivative represented by the general formula (I): STR1 (wherein R is a hydrogen atom, a C1-6 alkyl group, a C3-6 cycloalkyl group, a C1-6 haloalkyl group, a C2-6 alkenyl group or a C2-6 alkynyl group, R1 is a C1-6 alkyl group, X1 and X2, which may be the same or different, are halogen atoms, and Y is an oxygen atom or a sulfur atom) and at least one compound selected from the group consisting of sulfonylurea derivatives, phenylurea derivatives and phenoxy fatty acid derivatives; and a weeding method using said composition.
