Abstract
Procedimiento de preparacion de un polisulfuro orgánico estabilizado y desodorizado que consiste en tratar un polisulfuro orgánico bruto con un carbonatode alquileno en presencia de un catalizador básico. El carbonato de alquileno utilizado puede serel carbonato de etileno, el carbonato de propileno, elcarbonato de butileno o el carbonato de trimetileno y más generalmente todos los compuestos de formula I en la cual n es igual a 0, 1, o 2 y los símbolos R1,R2, R3 y R4, idénticos o diferentes,representan cada uno un átomo de hidrogeno o un radical alquilo. El catalizador básico ya puede estar contenido en elpolisulfuro bruto o puede agregarse al polisulfuro bruto. La mezcla se agita a una temperatura de aproximadamente 15 a 150sC duranteun tiempo de 2 minutos a10 horas. Puede ser ventajoso utilizar, en sinergia con el carbonato de alquileno, un dador de azufre que puede ser el azufre o un polisulfuro orgánico queposee 4 o más átomos de carbono por molécula. Los polisulfuros de la formula general RSnR en la cual n es un entero que va de 2 a 15 y donde R y R sonradicales hidrocarbilo opcionalmente sustituidos, son utilizados en numerosas aplicaciones tales como, por ejemplo, la presulfurizacion de catalizadores dehidrorrefinado yel agregado de elastomeros. También sirven como excelentes aditivos de extrema presion y antidesgaste para formulaciones de lubricantes paracajas de velocidad o para el trabajo en polisulfuro inodoro, exento de precipitados, claro y estable en el tiempo.
