Abstract: New and valuable herbicide comprising 1-phenyl-4-amino-5-chloro (or -5-bromo)-pyridazone-(6) which contains from 10 to 65 weight % of the active ingredient in the form of an aqueous suspension and, as dispersant, a condensation product of sulfonated phenols free from condensed ring systems with urea and formaldehyde in a molar ratio of 1:1 to 1.5:1.7 to 2.2, which condensation product has been after-treated with phenols and formaldehyde. The dispersion is extremely stable, even after prolonged storage periods. It can be readily mixed with other plant protection agents upon dilution. No dust problems occur when the spray liquors are prepared for use.

Abstract: A process for separating, by distillation, a mixture consisting essentially of 3,3-dimethylacrolein and 3-methyl-3-buten-1-ol, wherein the mixture to be separated is distilled in the presence of water and glycerol, the 3,3-dimethyl-acrolein first being distilled off azeotropically with water and the 3-methyl-3-buten-1-ol then being separated, as an azeotropic mixture with water, from the higher-boiling glycerol. It is also possible to isolate the 3,3-dimethylacrolein by distillation if the 3-methyl-3-buten-1-ol is partially replaced by 3-methyl-2-buten-1-ol. The 3,3-dimethylacrolein, which can be isolated in pure form by the process of the invention, is a valuable intermediate for the synthesis of natural substances such as citral, vitamin A and chrysanthemic acid.
