Abstract
La presente invención se refiere a un procedimiento para preparar disulfuros de dialquilo de C1-C12, caracterizado porque comprende hacer reaccionar continuamente un alcohol alquílico de C1-C12 y sulfuro de hidrógeno en una relación molar de 1:2 a 1:20, en contacto con un catalizador sólido en partículas, en una primera zona de reacción a una temperatura que varía desde alrededor de 100 hasta alrededor de 500 grados C; hacer pasar continuamente el producto mercaptano crudo de la reacción y azufre fundido, en una relación molar de 1:0.05 a 1:2, en contacto con un catalizador sólido, en partículas, en una segunda zona de reacción, a una temperatura que varía desde aproximadamente 125 hasta aproximadamente 400 grado sC, y recuperar el disulfuro de dialquilo de C1-C12.
