摘要： A novel method for preparing an aryl-substituted fatty acid or fatty ester is disclosed. According to the method, an olefinic composition selected from among mono-unsaturated fatty acids, mono-unsaturated fatty esters and mixtures thereof is introduced to a reaction zone comprising a liquid aromatic hydrocarbon and a catalytic amount of a clay catalyst to produce a reaction that is allowed to proceed for a time and at a temperature sufficient to produce a reaction product comprising a desired yield of aryl-substituted fatty acid or fatty ester. Preferably, the introduction of the olefinic composition is conducted slowly, such as over a period of one to four, more preferably, two to four, hours. Related methods and compositions, including xylylstearic acid, are also disclosed.

摘要： A method for inhibiting corrosion in an aqueous medium is disclosed. The method comprises incorporating into the medium an amount of a water-soluble corrosion inhibitor sufficient to inhibit corrosion. The corrosion inhibitor comprises an N-ethoxy, 2-substituted imidazoline, the N-ethoxy substituent having from one to about thirty ethoxy units and the 2-substituent being an unsaturated or polyunsaturated fatty chain of from about six to about thirty carbons. If the medium is sweet, the inhibitor further comprises a phosphate ester derived from a water-soluble oxyethylated, straight chain alcohol of from about two to about thirty carbons. Corrosion inhibitor compositions useful in such method are also disclosed.

摘要： This invention relates to hexahydropyrimidines (HHP) and to the preparation of HHP by the reduction of tetrahydropyrimidines (THP). HHP is preferably prepared by reacting carbonyls, such as ketones and aldehydes, with ammonia in the presence of ammonium formate to form THP and then reducing THP to HHP. The preferred carbonyl is a cycloalkylene ketone such as cyclohexyl ketone or substituted cyclohexyl ketone.
