Abstract: acid monoester, useful as raw material in the manufacture of synthetic resins and plasticisers, is produced from 2:2-dimethyl-3-hydroxypropanol obtained by reacting HCHO with isobutyraldehyde at elevated temps. in the presence of tert. amines. This reaction mixture, after removal of free amine, is then reacted at 120 - 175 degrees C in the presence of an organic salt of a tert. amine of mol. wt. below 250.

Abstract: 1308567 Production of aldehydes and ketones by the oxo process BADISCHE ANILIN- & SODA-FABRIK AG 24 July 1970 [26 July 1969] 35891/70 Heading C2C Aldehydes and/or alcohols are produced by the oxo process by reacting an olefinically unsaturated compound with carbon monoxide and hydrogen in the presence of a cobalt carbonyl compound at elevated temperature, super atmospheric pressure and the reactants being introduced into the reaction zone at high speed wherein the reactants are introduced into a mixing zone which is located in the reaction zone in which it extends in the direction of introduction of the reactants, the mixing zone having a diameter which is from twice to fifty times the mean diameter of the stream of reactants supplied and having a length which is from three to thirty times its hydraulic diameter. The diameter of a stream of reactants is the diameter of a circle having the same area as the cross-section of a wand nozzle or other inlet opening and the hydraulic diameter is the diameter of a cylindrical tube which exhibits the same pressure drop as the mixing zone in question having the same length and the same throughput.
