Abstract: Process for the preparation of 3-aryl-isobutanols of the general formula I … … in which… R and R are hydrogen or an alkyl or cycloalkyl radical with up to 8 C atoms, preferably an alkyl radical with 1 to 4 C atoms,… which is characterised in that arylcarbinols of the general formula II … … are reacted with n-propanol in the presence of catalytic amounts of an alkali metal hydroxide or alkali metal oxide at 250 to 350 DEG C in a closed reaction vessel. … The process is particularly important for preparing 3-aryl-isobutanols of the formula I in which R is an alkyl radical with 1 to 4 C atoms and R is hydrogen. The p-methyl-, p-isopropyl- and p-tert.-butylphenylisobutanols obtained in this way in very high selectivity are valuable precursors for the fragrances jasmorange, cyclamenaldehyde and Lysmeral (Lilial ) which are in high demand.

Abstract: Primary amines are prepd. by nitrile hydrogenation using a solid particulate catalyst derived from oxides of CO and/or Ni and contains Mn and/or H3PO4 and which is provided with longitudinal pore spaces opening out towards catalyst grain boundaries and is prepd. by a standard process, through addn. of fibrous, heat-removable particles to slurried catalyst compsn., heating and reducing in an H2 stream. Fibre type and quantity are chosen so that pore spaces have a dia. of 0.03-0.5 (0.1) mm and make up 4-10 vol. % of catalyst grain.

Abstract: Catalyst produced by reacting methanolamine with ethylene oxide used in the prodn. of methoxypropionitrile from acrylonitrile and methanol according to the Parent patent was found equally effective with respect to reactions of acrylonitrile with mono- or polyhydric alcohols contg. >=2C atoms. The resulting title cpds can be used as inters. in the prodn. of acid amides, amines or diamines, isocyanates, etc. The catalyst is relatively inexpensive.

Abstract: Alkoxypropylamines are prepd. by the catalytic hydrogenation of an alkoxynitrile in the presence of free phosphoric acid (0.1-10 wt. %). The nitrile is obtd. by the reaction of an alcohol with acrylonitrile, in the presence of a base as catalyst. The base is finally neutralised. Pref. the alcohol is a divalent 2-8C straight-chain alcohol e.g. 1,6-hexane diol, and the base is neutralised by phosphoric acid. Hydrogenation occurs at pref. 60-90 degrees C, 100-300 atm. H2 in the presence of 0.2-1.0% H3PO4 to give an improved yield (>95%) and purity (>99%) of prod. The amines can be used as precursors in the mfre. of plastics.
