Cyclohexylamine sulphate is removed from a fluid mixture thereof with cyclohexylammonium N-cyclohexylsulphamate in cyclohexylamine by filtering the mixture at a temperature between t DEG C and the boiling point of said fluid mixture, whereby t is calculated according to the formula t=62.0+90.1Z - 75.3Z2+40.9Z3 wherein Z is log10X and X is the number of parts by weight of cyclohexylammonium N-cyclohexylsulphamate per 100 parts of cyclohexylamine. |
