2-ethylhexanal reduction

Aldehyde Reduction. The results of 2-ethylhexanal reduction in 95% ethanol, 2-ethylhexanol, and hexane with the various types of polymer-bound borohydrides, sodium borohydride, and tetraethylammonium borohydride are shown in Table I. 

Ethylhexan-1 -ol is a useful building block for the pharmaceutical, food, cosmetic and chemical industries. The reduction of 2-ethylhex-2-enal to CS )-2-ethylhexan-l -ol by baker s... 

Commercially available 2-ethylhexanal (Eastman practical grade) is purified by fractional distillation b.p. 163-163.2°/atm., no 1.4133. Other aldehydes are conveniently prepared by the Rosenmund reduction.2 If the aldehyde is relatively unstable toward autoxidation,3 a catalytic amount (0.5-1.0 g.) of hydroquinone is added with the aldehyde-bromo ester solution. 

Reduction of Aldehydes and Hydroperoxides. Stock solutions of approximately 100-200 ppm of 2-ethylhexanal in 95% ethanol, hexane, ana 2-ethylhexanol were prepared. Accurate carbonyl assays were conducted (ASTM method E411-70, "Trace Quantities of Carbonyl Compounds with 2,4-Dinitrophenylhydrazine ) initial carbonyl levels were... 

Butanal is the starting material for the synthesis of the mosquito repellent 6-12 (2-ethylhexane-l,3-diol). The first step is an aldol condensation, and the second step is reduction of the aldehyde group to a primary alcohol.
