Abstract
La presente invención se refiere a procedimiento para la preparacíon de compuestos glicidilo mediante la racción de un compuesto que contiene por lo menos un grupo fenólico, por lo menos con la cantidad equivalente, calculada sobre el grupo fenólico, de una halogenohidrina en un solvente aprotónico substancialmente anhidro, en presencia de un compuesto básico sólido, substancialmente anhidro; caracterizado por el hecho de que: a) la reacción se lleva a cabo a una temperatura situada entre 40 y 80ºC, en presencia de carbonato alcalino, empleándose un solvente dipolar aprotónico con una constante de dielectricidad estática relativa de más de 25 (a 25ºC) y un momento dipolar eléctrico permanente de más de 2,5 D, que se caracteriza adicionalmente por una energía de transición de la banda de absorción solvatocrómica del N-(3,5-difenil-4-hidroxifenil)-2,4,6-trifenilpiridinoperclorato disuelto, entre 168 y 197,4 kj/mol (a una temperatura de 25ºC), o b) la reacción se lleva a cabo a una temperatura situada entre 60 y 80ºC en presencia de hidróxido alcalino y de un catalizador de transferencia seleccionado entre el grupo consistente en un compuesto de amonio y/o de fosfonio y el agua de la reacción que se forma se descarga continuamente y se emplea un solvente inerte, aprotónico, apolar, con una constante de dielectricidad estática relativa de menos de 8,0 (a 25ºC) y un momento dipolar eléctrico permanente de menos de 2,0 D, que se caracteriza adicionalmente por una energía de transición de la banda de absorción solvatocrómica del N-(3,5-difenil-4-hidroxifenil)-2,4,6-trifenilpiridinioperclorato disuelto entre 140 y 165 kj/mol ( a 25ºc).
