octadecanenitrile

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

Procedure: 300 g of stearonitrile were fed into a 1 liter autoclave and then 3 g of Catalyst A, 12 g of water and 1 g of 48% sodium hydroxide were put thereinto. After purging with nitrogen gas, the reaction was carried out under the hydrogen pressure of 2.0 MpaG at the reaction temperature of 120° C. The reaction-finishing point was determined at the point where the hydrogen gas was no longer absorbed. The reaction system was aged further for 15 minutes. Absorption of hydrogen gas proceeded smoothly and the absorption was completed in 0.8 hour. After finish of the reaction and aging, the reaction product was taken out from the reactor and the catalyst was removed off. Then, the reaction product was distilled and purified under 0.27 kPa at 220° C. Stearylamine was obtained with yield of 94%. After purging with nitrogen gas was carried out under the hydrogen pressure of 2.0 MpaG at the reaction temperature of 120° C no longer absorbed Absorption of hydrogen gas the absorption was completed in 0.8 hour After finish of the reaction the catalyst was removed off Then, the reaction product was distilled purified under 0.27 kPa at 220° C

Procedure: A stirred mixture of about 50.0 grams (0.19 mole) stearonitrile, about 11.7 grams (0.19 mole) ethanolamine, and about 1.2 grams (0.0048 mole) cadmium acetate dihydrate is heated at about 115 degrees C. to about 125 degrees C. under nitrogen for about 88 hours. The mixture is cooled and then dissolved in about 450 ml of methylene chloride and dried over magnesium sulfate. The mixture is then filtered. Residual solvent is removed from the filtrate by vacuum. About 58.6 grams of light yellow solid is obtained. The solid is recrystallized from about 300 ml of hexane. The recrystallized material is collected, washed, and dried, yielding about 4.7 grams with a melting point of about 77 degrees C. to about 90 degrees C. The resulting filtrate, rinses, material removed in the initial filtration step and about 200 ml additional hexane are combined, heated, and filtered using gravity. The product is stored in a refrigerator for several days. The formed crystals are collected, rinsed, and dried at 50 degrees C. under vacuum, yielding about 36.3 grams of white solid with a melting point of about 50 degrees C. to about 54 degrees C. to about 125 degrees C The mixture is cooled dried over magnesium sulfate The mixture is then filtered Residual solvent is removed from the filtrate by vacuum

Procedure: In a 500 ml SUS 316L stainless steel autoclave were charged 60 g of ethylene diamine, 267 g of stearonitrile and 2.5 g of titanium tetraisopropoxide. After addition of 1 g of water, the mixture was heated up to 210° C. with stirring and maintained at that temperature for 4 hours while removing ammonia produced in situ to maintain the pressure within the autoclave at 8-9 kg/cm2G. The resulting mixture was then subjected to vacuum distillation at 0.6 mmHg and at 230°-235° C. to obtain 267 g of 2-heptadecyl-2-imidazoline with a yield of 86%. maintained at that temperature for 4 hours while removing ammonia produced in situ to maintain the pressure within the autoclave at 8-9 kg/cm2G The resulting mixture was then subjected to vacuum distillation at 0.6 mmHg and at 230°-235° C.
