Versuchsvorschrift
In U.S. Pat. No. 5,146,004, 2-ethyl-2-(hydroxymethyl) hexanal is prepared from 2-ethyl hexanal, formaldehyde and a tertiary amine. Any unreacted 2-ethyl hexanal can be isolated by azeotropic distillation of the organic phase of the raw product, and 2-butyl-2-ethyl-1,3 propane diol is obtained from the purified organic phase of the raw product by catalytic hydrogenation, with a yield of 85-88%. The hydrogenation is carried out by using a nickel catalyst.
