    Abstract: An aliphatic diol mixt. (I) contains 70-95 wt.% HOCH2.CHPr.CHEt.CH2OH (II) and 5-30 wt.% HOCH2.CHEt.CH2.CHEt.CH2OH (III). (I) is prepd. by hydroformulation of CH3.CH2.CH2.CH:CHEt.CH2OH (IV) with CO and H2 at 60-130, pref. 70-120 degrees C and 30-300, pref. 150-250 atm. in the presence of Rh carbonyl complexes (V); and hydrogenation of the resultant mixt. of 2-hydroxy-3-propyl-4-ethyl-tetrahydrofuran (VI) and 3,4-diethyltetrahydropyran (VII) in the presence of a hydrogenation catalyst at elevated temp. (50-250, esp. 60-200 degrees C) and elevated pressure (20-300, esp. 50-200 atm.). (V) pref. is used in conjunction with a tert. organic phosphine (VIII), esp. PPh3 or P(C6H3Me2-p)3, in an amt. of 3-50, pref. 5-50 mole (VIII/g-atom Rh. (I) is used in the prodn. of polyurethanes and polyesters, giving polymers of low crystallinity and hence better toughness and plasticisity.
