Abstract

PROCEDIMIENTO PARA DISMINUIR EL CONTENIDO DE CLORO EN LOS COMPUESTOS GLICIDILICOS. COMPRENDE: A) HACER REACCIONAR AL COMPUESTO GLICILICO CON UN HIDRURO DE ESTAÑO DE FORMULA (R3SNH) O (RSSNH2), EN PRESENCIA DE UNA CANTIDAD CATALITICA DE UN INICIADOR FORMADOS DE RADICALES LIBRES A UNA TEMPERATURA ENTRE 60 Y 100JC, Y EN DISOLVENTES COMO HEPTANO, OCTANO, TOLUENO. SIENDO: R2 Y R3 ALQUILO DE C 1 A 4; B) ELIMINAR EL COMPUESTO GLICIDILICO DEL DISOLVENTE; C) DISOLVER AL COMPUESTO GLICIDILICO EN ACETONITRILO; Y D) LAVAR A LA SOLUCION DE C) CON HEXANO. EL COMPUESTO GLICIDILICO SE ELIGE ENTRE LOS DERIVADOS DE N-GLICIDILICOS DE AMINA, Y LOS DERIVADOS N,N-DIGLICIDICOS DE ALQUILENUREAS CICLICAS Y EL ISOCIANATO DE TRIGLICIDILO, EL HIDRURO DE ESTAÑO SE ELIGE HIDRURO DE TRI-N-BUTIL-SN, HIDRURO DE TRIETIL-SN O HIDRURO DE TRIFENIL-SN Y EL INICIADOR FORMADOR DE RADICALES LIBRES SE ELIGE ENTRE LA 2-HIDROXI-2-METIL-1-FENIL PROPANONA-1, AZO-BIS-TISOBUTIVORUTRICO Y PERBORATOS ALCALINOS.
