ABSTRACT:
The production of 3-methylpentane-1,5-diol by hydroformylation of 2-methylbut-1-en-4-ol with carbon monoxide and hydrogen at elevated temperature and superatmospheric pressure in the presence of a rhodium carbonyl complex which has been modified by a tertiary organic phosphine followed by hydrogenation of the 2-hydroxy-4-methyltetrahydropyran at elevated temperature and superatmospheric pressure in the presence of a hydrogenation catalyst.
