In a 5 L flask, 3.5 L of ethanol and 342 g of tetradecanoic acid were added, stirred and dissolved, and a solution having a density of 0.91 g / mlAmmonia 288ml, stirring at room temperature for 0.5 hours, and then cooled to 0 ° C crystallization, filtration, filter cake washed with ethanol, filter cake at 40 ° C vacuum drying to be 306.9gAmmonium myristate, the yield was 83.5%. The prepared ammonium myristate was added to a 5 L flask, and 3 L of water was added thereto, and the mixture was stirred uniformly. The pH was adjusted to about 2 with hydrochloric acid. The filter cake was washed with water and dried in vacuo at 30 ° C to give 272.1 g of tetradecanoic acid in a yield of 95.3%, chemical purity of 99.18%.
