Abstract
1. A process for regenerating chlorinated hydrocarbons in dry-cleaning by filtration and distallation, characterized in that the filter mass consists wholly or in part of a finely particulate, water-insoluble aluminium silicate containing bound water and corresponding to the following general formula (Cat2 O)x .Al2 O3 .(SiO2 )y , in which Cat is an alkali metal ion, x is a number of from 0.7 to 1.5, y is a number of from 0.8 to 6 and preferably from 1.3 to 4, said aluminium silicate having an X-ray amorphous or crystalline structure and a particle size of subtantially 1 to 100 mu.
