Abstract

Un procedimiento para la producción de un agente de recurtido e impregnación con grasa o aceite que es el producto de condensación sulfonado de: (a) un componente de hidroxi seleccionado del grupo formado por fenol y alquil (inferior) fenol que tiene por lo menos un alquilo de 1 ó 2 átomos de carbono y por lo menos un hidrógeno reactivo en la posición 2,4 ó 6 del alquilfenol; (b) un aceite no saturado, y (c) una composición de liberación de formaldehído donde el contenido de SO3 de dicho producto de condensación sulfonado es de 0,3 a 1,5 moles aproximadamente de SO3 por mol del componente hidroxi.
