实验步骤: The acid chloride of 1-triacontanoic acid is converted to the ester by adding methanol or ethanol and stirring for 1/2 to 1 hour. The alcohol was evaporated on a rotary evaporator leaving ethyl-1-triacontanoate. The ester is then reacted in a pressure vessel under about 250 atmospheres of hydrogen in the presence of a powdered copper chromite catalyst for about 12 hours at 250° C. to produce 1-triacontanol. One part of catalyst is present for every 5 to 10 parts of ester.

实验步骤: Triacontanol is prepared from triacontanoic acid by suspending 0.1 mol of the acid in 40 ml of anhydrous chloroform followed by the addition of thionyl chloride while maintaining the temperature at 40° C. for 2 hours. Chloroform and excess thionyl chloride were removed in a rotary evaporator, and the resulting acid chloride was reacted with 10 ml of absolute ethanol to form the ester. Excess ethanol was removed in a similar manner, and the ester was dissolved in 100 ml of anhydrous ether. Chloroform and excess thionyl chloride were removed in a rotary evaporator the resulting acid chloride was reacted with 10 ml of absolute ethanol
