Abstract: A process for reducing the dimerisation of piperidines of formula (I), in which R -R = 1-6C alkyl, or R /R or R /R together may form a CH2 chain with 2-5 C atoms. The process comprises adding to (I) 0.001-0.2 wt% of a reducing agent of formula MXH4-mYm (III), in which M = alkali metal, NR4 (with R = 1-4C alkyl) or one equivalent of alkaline earth metal or zinc; X = boron or aluminium; Y = H or CN; m = 0 or 1. Also claimed is a mixture containing (A) a piperidine of formula (I), (B) 1-1000 ppm of a compound of formula (II) and (C) 0.001-0.2 wt% reducing agent (III).
