The preparation and properties of some petroselinylamine derivatives

Petroselinylamine (cis-6-octadecenylamine) has been prepared by an improved process in which petroselinic acid in xylene is subjected to ammonolysis and treated further to yield the pri-mary amine without isolating the intermediate products. In addition, the petroselinylamine has been reacted with acrylonitrile, followed by reduc-tion with metallic sodium and alcohol, to give N-substituted petroselinyl-l,3-trimethylenediamine adducts, and with ethylene oxide under pressure to yield the oxyethylated tertiary amine deriva-tives. The crude products in each case were mix-tures of derivatives of various molecular weights. It was possible to isolate the N-petroselinyl-1,3-trimethylenediamine in its pure form from the crude mixture of hydrochloride salts by repeated recrystallizations from aqueous ethanol. The mix-ture of petroselinylamine-ethylene oxide deriva-tives could not be separated. 1 Presented at the AOCS Meeting, Cincinnati, October 1965. 2 So. Utiliz. Res. Dev. Div., ARS, USDA.     

Preparation of vinyl esters of some chlorinated new oilseed crops fatty acids

Several mixtures of fatty acids derived from the seed oil of plants being investigated as new crops, have been chlorinated and the chlorinated acids have been converted to the vinyl esters. These products have potential utility as comonomers in vinyl polymerizations. So. Utiliz. Res. Dev. Div., ARS, USDA.     

The preparation and properties of some nitrogen-containing derivatives of petroselinic acid

Petroselinonitrile was prepared by distilling the ammonolysis products of petroselinic acid over phosphorus pentoxide, and also from parsley seed oil without first isolating the petroselinic acid. A high-boiling antioxidant was employed during the reaction to control polymerization. The reaction by-products were segregated from the pure petroselinonitrile by urea complexing. Petroselinamide was obtained from petroselinic acid by the acidolysis of urea. Although it was not possible to reduce the petroselinonitrile by catalytic hydrogenation without affecting the ethylenic linkage or without producing a mixture of the primary, secondary, and tertiary amines, petroselinonitrile was converted to primary petroselinylmine in good yields by reduction with metallic sodium and alcohol in toluene. The hydrochloride and the acetyl derivative of the pure primary amine have also been prepared. Presented at the AOCS meeting in New Orleans, Louisiana, May 7–9, 1962.

Chemical inactivation of aflatoxins in peanut and cottonseed meals

Organic and inorganic reagents have been tested for destruction or inactivation of the aflatoxins present in peanut and cottonseed meals. The treatments were made in a special laboratory-scale reactor, and were evaluated by determination of the aflatoxins in the products by thin layer chromatography. In some instances, a larger pilot-plant scale reactor was used. Ammonia, methylamine, sodium hydroxide and formaldehyde reduced aflatoxin levels and appear practical for large scale treatments. Effects of various reaction parameters including time, temperature and moisture content on the efficiency of these reagents are presented. Presented at the AOCS Meeting, San Francisco, April 1969.

Oil from calabash seed,Crescentia cujete L.

Summary The composition and characteristics of calabash,Crescentia cujete L., seed and oil have been determined. The oil was found to have the following composition calculated from the iodine and thiocyanogen values, and saturated acid content of mixed fatty acids: saturated acids 19.7%, oleic acid 59.4%, linoleic acid 19.3%, and linolenic acid 1.6%. Comparison of the composition and characteristics of calabash seed oil with those for peanut and olive oil indicate that, except for the presence of a small amount of linolenic acid in the former, the oils are similar.
