Agrochemical formulations

A new process for preventing the crystallization of certain azole derivatives in the spray equipment upon spraying mixtures containing

Use of phosphoric esters as crystallization inhibitors

In the spraying of an aqueous liquor comprising at least one of 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-pentan-3-ol and 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol, the improvement which comprises including in the liquor an N-alkyl-lactam of the formula ##STR1## in which R represents alkyl having 8 to 18 carbon atoms and

N-alkyl-lactams as crystallization inhibitors

Crystallization of active material in spraying an aqueous solution of one of ##STR1## and is prevented by incorporation therein of an alkylcarboxylic acid dimethylamide of the formula ##STR2## in which R represents alkyl having 5 to 19 carbon atoms.

Alkylcarboxylic acid dimethylamides as crystallization inhibitors

The invention relates to a process in which a melt is mixed with, and emulsified in a colder aqueous phase at a temperature below the crystallization point of the molten compound, the melt only solidifying in the form of the dispersed particles after the emulsification step. To this end, the melt is sprayed into the aqueous phase to form a preliminary emulsion (12) and the preliminary emulsion is finely dispersed for 0.005 s to 0.15 s in a following homogenization nozzle (8) to form an emulsion (15) which then solidifies to form the final crystal suspension. The particle size can be clearly and reproducibly adjusted through the nozzle pressure during the emulsification step. The process may be used in particular for the production of highly concentrated dispersions of high-melting organic materials.

A self-levelling mortar mixture containing anhydrite, activator salts, plasticizers, surfactants and water is improved by providing the anhydrite in the form of both coarse-grained particles and finely ground particles.
