Abstract

1. Procedimiento para la obtención de sales alcalinas de ésteres de ácido hidroxibenzóico, ampliamente anhidro y libres de ácido hidroxibenzóico, de fórmula **(Fórmula 01)** donde R1 significa alquilo, alquenilo, cicloalquilo o aralquilo, R2 y R3 son iguales o diferentes y significan hidrógeno, halógeno, hidroxi, amino, alquilamino, alquilo, alcoxi, aralquilo o arilo y Me significa un metal alcalino, caracterizado porque una solución o suspensión de un éster de ácido hidroxibenzóico de fórmula **(Fórmula 02)** donde R1, R2 y R3 tienen los significados de arriba, se neutraliza con un hidróxido alcalino a -10 hasta + 50ºC hasta un grado de neutralización de 0,95 hasta 1,05, significando en grado de neutralización 1,00 el punto de equivalencia de la neutralización del grupo OH fenólico por el hidróxido alcalino y la solución o suspensión, así obtenida, de la sal alcalina del éster de ácido hidroxibenzóico se alimenta a un secado protector del producto, en si conocido, tan a tiempo de manera que el contenido en ácido hidroxibenzóico o bien de su sal alcalina en esta solución o suspensión no alcance el valor de un 1% en peso, referido a la cantidad de sal alcalina de éster de ácido hidroxibenzóido contenida en esta solución o suspensión.
