Abstract

UNA COMPOSICION QUE CONTIENE PREDOMINANTEMENTE FOSFINATO QUE TIENE COMO INGREDIENTE MAYORITARIO MAS DE 32% DE MOL DE UN OLIGOMERO DE ACIDO FOSFINICOSUCCINICO QUE TIENE LA PROBABLE FORMULA ESTRUCTURAL: M ES H, NA, K, NH SUB 4, O MEZCLAS DE ESTA; Y M Y N SON O O UN NUMERO ENTERO PEQUEÑO SIEMPRE Y CUANDO M O N SEA UN NUMERO ENTERO PEQUEÑO Y QUE LA SUMA DE M MAS N SEA MAYOR DE 2. TAMBIEN SE PRESENTA UN METODO PARA HACER ESTAS COMPOSICIONES, QUE PROVOCA LA REACCION DE UN ACIDO MOLEICO CON EXCESO DE HIPOFOSFITA SOLUBLE EN AGUA, CON UNA RELACION MOLAR DE 2.3 A 3, Y EL USO DE ESTAS COMPOSICIONES Y DEL OLIGOMERO PARA PREVENIR O INHIBIR LA FORMACION DE ESCAMAS EN MEDIOS ACUOSOS, PARTICULARMENTE EN AGUA DE REFRIGERACION ALCALINA.
