CA 2205597

The direct handling of acrolein for combating microbial, plant and animal parasites in water and soil is problematic owing to the potential risks posed by acrolein. According to the invention, an easy-to-handle acrolein-releasing composition is used, the acrolein being released at the site of use owing to contact with water. This composition contains (i) an acrolein acetal having a C1 to C6 alcohol with 1 to 4 hydroxyl groups and (ii) a chemically compatible acid which is soluble therein and has a pK s value of less than 4 and (iii) is anhydrous. A preferred composition contains as acetal 2-vinyl-1,3-dioxolane, as acid, anhydrous oxalic acid, furnaric acid or maleic acid or a mixture of mono and di(C1 to C3)alkylphosphate and additionally a nonionic surfactant.

La manipulation directe d'acroléine pour lutter contre des parasites microbiens, végétaux et animaux dans l'eau et dans le sol, est problématique en raison des risques potentiels que suscite l'acroléine. Selon l'invention, il est prévu d'utiliser une composition apte à la libération d'acroléine, facile à manipuler, dans laquelle l'acroléine est libérée au point d'utilisation, par mise en contact avec de l'eau. Cette composition contient (I) un acétal d'acroléine ayant un alcool C1-C6 comportant entre 1 et 4 groupes hydroxyle et (ii) un acide soluble dedans et chimiquement compatible, ayant un indice pKs inférieur à 4, et est exempte d'eau (iii). Une composition préférée contient comme acétal, du 2-vinyle-1,3-dioxolane, comme acide, de l'acide oxalique exempt d'eau, de l'acide fumarique ou de l'acide maléique ou un mélange de mono- et de dialkylphosphate (C1-C3), ainsi qu'un tensioactif non ionique.
