实验步骤: A mixture of 104 gms. (0.348 moles) of arachidyl alcohol, 46 gms. (0.362 moles) of benzoic acid and 225 mgms. stannous oxalate was heated under nitrogen to 230° C. The reaction was held at 230° C. for two hours under nitrogen. The acidity was 10 mgms. KOH/gms. The mixture was then cooled to 100° C. During the reaction distillate was collected. The ester formed was solid at room temperature and showed solidication at 80° C. The ester was given a treatment at 85° C. with 50 gms. deionized water containing 2 gms. sodium carbonate, 2 gms. sodium chloride and 1 gm. hydrogen peroxide. The mixture was allowed to stand and separate. The top layer was washed with 50 gms. deionized water at 80°-85° C., separated and cooled. The top layer solidified and bottom layer was completely drained off. The ester was then vacuum stripped at 100°-105° C. The ester so formed was a white solid benzoate. A mixture of 104 gms During the reaction distillate was collected

实验步骤: 2.9 g of 1-eicosanol dissolved in 50 ml of anhydrous pyridine are placed in a 100 ml flask equipped with a stirrer, a thermometer and a dehydrating valve. To this solution there are added 2.5 g of trimethoxycinnamoyl chloride and 0.01 ml of POCl3. The reaction mixture is left alone at room temperature overnight and is then poured into 200 ml of water. After filtration, the precipitate formed is crystallized from 30 ml of methanol. After drying, 4.2 g of eicosyl trimethoxycinnamate having the following characteristics are obtained: are placed in a 100 ml flask equipped with a stirrer After filtration the precipitate formed is crystallized from 30 ml of methanol After drying

实验步骤: In a three necked flask equipped with a dropping funnel, a thermometer and a reflux condenser, n-eicosanol (182 g) was dissolved in toluene (1250 ml) in a nitrogen atmosphere. To the solution, p-nitrophenyl isocyanate (100 g) was gradually added, and the mixture was stirred at room temperature for 10 minutes and then heat-refluxed for 30 minutes. When the reaction liquid was cooled to room temperature, crystals precipitated. The crystals were collected by filtering and washed with toluene. n-eicosyl p-nitrophenylcarbamate (270 g) was obtained at a yield of 96%. In a three necked flask equipped with a dropping funnel heat-refluxed for 30 minutes When the reaction liquid was cooled to room temperature crystals precipitated The crystals were collected by filtering washed with toluene
