摘要

Optimized process for degreasing and/or scouring metal, ceramic, glass, plastic composite material or semiconductor surface, comprises plunging the surfaces in a solution comprising an ionic liquid having heterocyclic compound; and subjecting the solution to ultrasounds at 20-120[deg] C. Optimized process for degreasing and/or scouring metal, ceramic, glass, plastic composite material or semiconductor surface, comprises plunging the surfaces in a solution comprising an ionic liquid having heterocyclic compound formula (Q +[RCOO] -); and subjecting the solution to ultrasounds at 20-120[deg] C. Q +organic or inorganic cation; and R : 1-10C organic radical.
