A process for reducing the odor of an oil. The oil being treated is first distilled by a carrier vapor or carrier gas distillation to form a distilled oil. The distilled oil is then contacted with a polymeric adsorbent; whereby the odor of the oil is reduced. The polymeric adsorbent is regenerated. The polymeric adsorbent can be a cross-linked polymer with an internal surface area of from 900 to 1500 m/gram.

Reducing the odor of oil components by means of adsorption with polymeric adsorbing agents

The present invention relates to a new process for obtaining fatty acids with improved color, odor and heat stability which is characterized in that:

Process for obtaining fatty acids with improved odor, color and heat stability

Processes for producing branched compounds are described wherein a carbonyl compound is condensed in the presence of a catalyst selected from the group consisting of acids and bases, to form an &#x3b1;,&#x3b2;-unsaturated condensation product; and the &#x3b1;,&#x3b2;-unsaturated condensation product is hydrogenated.

Processes for producing branched compounds via condensation and hydrogenation

A process for making aldehydes involving: (a) providing a fatty alcohol; (b) providing an oxidic copper/zinc catalyst; and (c) continuously dehydrogenating the fatty alcohol, in the presence of the oxidic copper/zinc catalyst, at a temperature of from about 200 to 280&#xb0; C. and a pressure of from about 10 mbar to 1 bar.
