Abstract

Ces composés ont la formule ci-après. On fait réagir, dans un milieu hydro-alcoolique, un composé phénolique non substitué ou para-substitué avec le méthylol résultant de la réaction entre le formaldéhyde et un sel alcalin ou alcalinoterreux d'un acide hydroxyéthyl-alcoylène-diamino-diacétique ou d'un acide dihydroxyéthyl-alcoylène-diaminoacétique, à une température comprise entre 60 et 100 degrés C et à un pH compris entre 8 et 11. Les composés obtenus sont capables de former des produits de chélation solubles avec le fer et d'autres métaux stables contenus dans les sols calcaires, ce qui fait qu'ils conviennent pour corriger les carences en oligoéléments de certaines cultures de plantes.
