New, non-hygroscopic, crystalline mono-ammonium salts of general formula (I), where, R1 stands for hydroxy or alkyl; -A stands for 1-4 alkyl-amino- or amino-alkyl-groups containing primary or secondary amino-groups, preferably -CH2-NH- or -CH(NH2)-CH2-groups; B stands for ammonium, -ion, or alkyl-substituted ammonium-ion- as well as processes to obtain the same by preparing the mono-ammonium salt of general formula (I), according to any method known generally for the preparation of salts, whereby, along with avoiding other contaminations, on the course of or after salt-formation the di-ammonium salt of general formula (V). where, -R1, A and B stand for the above, is eliminated or its formation is repressed. Herbicidal or plant-growth-regulating compositions containing the non-hygroscopic salts, processes for their preparation and methods of treatment of unwanted plants and weed as well as a composition consisting of a bag, which is solid and preferably flexible in its dry state, which is made of a water-soluble polymer and which contains the new substances or compositions.
Nouveaux sels de monoammonium cristallisés non hygroscopiques de formule générale (I), dans laquelle R1 est un hydroxy ou un alkyle; -A représente 1-4 alkyl-amino- ou amino-alkyle, renfermant des groupes amino primaires ou secondaires, de préférence -CH2-NH- ou -CH(NH2)-CH2-; B est l'ion ammonium avec ou sans substitution alkylique; méthode d'obtention par préparation du sel de monoammonium de formule générale (I), selon n'importe quelle méthode connue de préparation de sels, où, tout en évitant d'autres contaminations pendant ou après la formation du sel, on élimine ou on empêche la formation de sel de diammonium de formule générale (V), dans laquelle -R1, A et B ont la signification ci-dessus. Compositions herbicides ou régulatrices de la croissance des plantes, renfermant ces sels non hygroscopiques; méthodes pour les préparer et méthodes pour le traitement de plantes indésirables et de mauvaises herbes; composition sous forme de sac solide et de préférence flexible à l'état sec, fabriqué à partir d'un polymère hydrosoluble et qui renferme les nouvelles substances ou compositions.
