摘要: The disclosure provides methods of synthesizing very long chain fatty acids, including deuterated very long chain fatty acids. The fatty acids can by polyunsaturated fatty acids. The methods include the step of reacting a protected leaving group (L)-substituted saturated aliphatic group with a halo-substituted unsaturated aliphatic group to form a protected aliphatic group. The protected aliphatic group is deprotected to form an alcohol. The alcohol is then oxidized, thereby forming a very long chain fatty acid.

摘要: Processes are described for purifying a biphenyldicarboxylic acid product containing one or more impurities, particularly at least formylbiphenylcarboxylic acid. In the processes, a mixture comprising the biphenyldicarboxylic acid product is contacted with hydrogen in the presence of a hydrogenation catalyst under conditions to selectively reduce at least part of the formylbiphenylcarboxylic acid to produce a hydrogenation effluent comprising (i) hydroxymethylbiphenylcarboxylic acid and/or methylbiphenylcarboxylic acid, and (ii) biphenylcarboxylic acid. At least a portion of the biphenyldicarboxylic acid is then separated from the hydrogenation effluent. Advantageously, a polyester product may be produced from the separated biphenyldicarboxylic acid.
