HCID 5281Stearic AcidYield 55%

Procedure

Using the procedure described in Example 1 and substituting therein 20 g. of a purified commercial grade of oleic acid (cis-9 -octadecenoic) acid for the palmitic acid and employing 5 g. of catalyst and adjusting the deuterium flow rate to 150 ml./minute, there is obtained after 15 days of exchange a 55% yield of stearic acid of 99 atom % D.
