Abstract:
A fungicidal composition which is a synergistic mixture of 2(methoxycarbamoyl)-benzimidazole and an N-substituted phthalimide having a combined fungicidal action greater than the sum of actions of the individual components. The composition is especially useful in preventing fungus growth on seeds and plants.
Abstract:
The production of o-sulfamidobenzoic acids by reaction of anthranilic acid or one of its salts with a sulfamyl halide in the presence of a polar solvent at a temperature of from 15* to 40*C. The products are starting materials for the production of plant protection agents and dyes.
Abstract:
The invention relates to a method for producing acrylic acid or an acrylic acid ester, comprising step A, optionally, step B and optionally, step C as follows: A. cooling a gaseous reaction mixture formed during the gas phase oxidation process for producing acrylic acid and containing acrylic acid using an acrylic acid containing at most 5 wt.% water to form a gaseous mixture containing (meth)acrylic acid; B. separating the gaseous mixture containing acrylic acid to obtain a light-boiling fraction and a bottom product containing crude acrylic acid; and C. esterifying the crude acrylic acid obtained in step B using one or more alkanols to produce an esterification mixture containing one or more acrylic acid esters, one or more acetic acid esters, one or more maleic acid esters and oligomeric and polymeric acrylic acid esters.
Abstract:
New 4-oxa-5-hydroxypolycycloalkenones-(3) and a new method for their Production by Diels-Alder reaction of cycloalkapolyenes with 2-hydroxy-2,5-dihydrofuran-5-ones. The new and known compounds obtainable by the process of the invention are starting materials for the production of dyes, plastics, pharmaceutical products and pest control agents.

Abstract:
A process for preparing acrylic acid and/or acrylates, which comprises stage A with or without stages B and C:A: cooling a gaseous reaction mixture which comprises acrylic acid and is obtained in the gas-phase oxidation to prepare acrylic acid, using an inert high-boiling solvent, to give a gaseous mixture comprising acrylic acid;B: separating the gaseous mixture comprising acrylic acid to give a low-boiling fraction, a crude acrylic acid, and a bottom product, andC: esterifying the crude acrylic acid obtained in stage B by means of one or more alkanols to give an esterification mixture comprising one or more acrylates and one or more acetic esters.
