Title (EN) AN ANTI-CAKING AGENT
(FR) AGENT ANTI-AGGLUTINANT
Abstract:
(EN) The present invention relates to an anti-caking agent for the treatment of granulate products, where the anti-caking agent is a salt having the general formula (Ia): R1-AB-R2-BA-R1, or the general formula (Ib): R1-BA-R2-AB-R1, in which the groups R1 independently represent monovalent hydrophobic organic groups, the group R2 represents divalent hydrophobic organic groups, the groups A represent independently anionic groups and the groups B represent independently cationic groups. The groups A preferably represent carboxylate ion groups and the groups B preferably represent ammonium ion groups. An anti-caking agent of this kind is very suitable for inhibiting the caking tendency of fertilizers.
(FR) Agent anti-agglutinant pour le traitement de produits granulés, constitué d'un sel de formule générale (Ia): R1-AB-R2-BA-R1 ou de formule générale (Ib); R1-BA-R2-AB-R1, dans lesquelles les groups R1 représentent indépendamment des groupes organiques hydrophobes monovalents, le groupe R2 représente des groupes organiques hydrophobes divalents, les groupes A représentent indépendamment des groupes anioniques et les groupes B représentent indépendamment des groupes cationiques. Les groupes A représentent de préférence des groupes à ion carboxylate et les groupes B représentent de préférence des groupes à ion ammonium. Un agent anti-agglutinant de cette nature est très efficace pour inhiber la tendance à l'agglutination des engrais.
