Patent

CA 2671316

Novel reactive phosphonate compounds are disclosed corresponding to the structural formula set forth. The reactive moiety is preferably selected from the group of C1, I, Br, HSO4, NO3, mixtures of C1 and I, CH3SO3 and p-toluene sulfonic acid whereas the hydrocarbon linking group between the nitrogen and the reactive moiety is most preferably a linear hydrocarbon chain having fro 3 to 12 carbon atoms. The novel phosphonates herein can be used in multiple established applications, such as detergency, water treatment, oil recovery, pharmaceutical intermediate and pharmaceutical products. The novel compounds are particularly useful for the "tailor" synthesis of optimized structural arrangements capable of meeting beneficial performance requirements.

Composés phosphonates correspondant à la formule structurelle indiquée. De préférence, la fraction réactive appartient à la série:C1, I, Br, HSO4, NO3, mélanges de C1 et I, CH3SO3 acide sulfonique p-toluène. Le groupe de liaison hydrocarboné entre la fraction azote et la fraction réactive est de préférence particulièrement une chaîne linéaire hydrocarbonée ayant entre 3 et 12 atomes de carbone. Les composés décrits peuvent être utilisés dans de multiples applications établies, du type: action détergente, traitement des eaux, récupération de pétrole, intermédiaire pharmaceutique et produits pharmaceutiques. Ces composés sont particulièrement utiles pour la synthèse "personnalisée" de configurations structurelles optimisées capables de répondre à des exigences de performance bénéfiques.
