heptadecanoic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: At the end of the six-week period, the second group of 5 rats was switched to a diet of menhaden fish oil (35% of total calories), protein (about 25% of total calories) and dextrose (remainder of total calories) for two weeks with vitamins and minerals continued as before. The menhaden fish oil was found by analysis to contain the following percentages of fatty acids (total fatty acid basis): 0.2% C12:0, 10.3% C14:0, 1.1% C15:0, 20.0% C16:0, 1.2% C17:0, 3.4% C18:0, 2.1% C20:0, 14.8% C16:1, 0.3% C17:1, 12.3% C18:1, 2.6% C20:1, 0.6% C22:1, 0.2% C24:1, 1.6% C16:2, 2.0% C18:2, 3.7% C18:3, 0.5% C20:2, 0.4% C20:3, 0.7% C20:4, 9.8% C20:5, 1.8% C22:5, 6.1% C22:6 and 1.6% unknown and C19:1 alcohol, providing totals of 38.3% saturated fatty acid and 26.6% polyunsaturated fatty acid. At the end of the two-week period, the five rats of this group were sacrificed and determinations were made as described below.

Procedure: N,N-dimethylheptadecylamine (b.p. 117° @ 0.15 mmHg) was prepared from dimethylamine and heptadecanoic acid by the method described in Example 14.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: After the reaction, the autoclave was cooled with ice, and the pressure was reduced; subsequently, the reaction mixture was analyzed by FT-NMR using coumarin as an internal standard. The results confirmed that heptadecanoic acid was obtained in a yield of 78%, and heptadecanal was obtained in a yield of 21%. After the reaction the autoclave was cooled with ice was obtained in a yield of 78%

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a one L (liter) two-necked flask were placed 102.1 g (0.38 mol) of heptadecanoic acid and 200 milliliter (mL) of cyclohexane, and the flask was equipped with a 100 mL dropping funnel containing 67.3 g (0.57 mol) of thionyl chloride and a reflux tube. Then, the heptadecanoic acid was completely dissolved under heating and stirring of the flask in an oil bath at 80° C. Thereafter the thionyl chloride was added dropwise over a period of 2 hours, and further the oil bath was maintained at 80° C. for one hour. From the resultant reaction mixture were removed the cyclohexane and the thionyl chloride under reduced pressure by means of an aspirator. The resultant reaction mixture was subjected to vacuum distillation. Thus 88.5 g (0.31 mol) of heptadecanoyl chloride was obtained in a yield of 81.2% based on the fed heptadecanoic acid. the flask was equipped with a 100 mL under heating further the oil bath was maintained at 80° C. for one hour From the resultant reaction mixture were removed the cyclohexane The resultant reaction mixture was subjected to vacuum distillation
