Abstract

In the parent patent a homogeneous liq. contg. 90-99.95% of a solvent contg. >50 wt.% of trichloro 1,1,2-trifluoro-1,2,2-ethane and 10-0.05% of a salt of >=1 diamine of formula R-NH(CH2)nNH2 (in which R is sat. or unsat. aliphatic residue of 1-25C and n is 1-9) with >=1 10-30C aliphatic acid contg. >=1 ethylene bond, for eliminating water from the cleaning surfaces. This improvement comprises a continuous process in which the surface is immersed in a bath of the liq. followed by a boiling rinsing bath, and is held for a short time in the vapour from the bath before taking out of the equipment. The vapours are condensed, sepd. from water and returned to the baths.
