Abstract

Tert. amines of general formulan R1N(R)CH3 (1) (where R= a cyclohexyl R1=R or alkyl), prepd. by methylation with formaldehyde, are purified as follows: raw prods. are subjected to a preliminary distillation to remove methanol, formaldehyde and part of the water. 8-12C aryl alkanes and/or cycloalkyl-alkanes are added to the resulting mix at a 5-20 fold concn. based on the combined mass of residual water and/or formic acid present, as formates. This mixt. is boiled for 4-10 hrs. in this case with a stream of inert gas bubbling through and/or at reduced pressure. Fractions are continuously removed and condensed, which aryl and/or cyclo-alkyl alkanes are simultaneously recirculate
