Patent No.90 109608 is a production process of anethole with high freezing point, with anethole with freezing point below 20℃ as raw material. Characterized in that 1. coarse brain is used for preparing fennel oil with a freezing point below 65438 0, and is frozen to 8-65438 0 5 DEG C under stirring. 2. Add fennel oil whose freezing point is greater than 15℃ into the solvent (about 1/4 of the oil amount), and then stir and freeze for crystallization at the freezing temperature of 0 ~ 15℃. After the crystal is completely precipitated, it is separated from the crystallization solution, and the fennel oil terpene and solvent solution are removed to obtain coarse brain. The terpene solvent solution of fennel oil is sent to fractionation. 2.2 1℃ Preparation of refined brain with high freezing point: Add solvents (ethanol and acetone) with the amount of not less than 1/2 brain to the coarse brain, recrystallize at 0- 15℃, and separate and remove the solvent and the mixture of fennel oil terpenoids dissolved in the coarse brain to obtain fennel crystals. The dosage of the solvent is not less than 1/3 of the brain amount. After washing, the solvent was separated, and the anethole was crystallized and rectified to remove the residual solvent and terpene in the fennel oil, thus obtaining the refined anethole with a high freezing point above 265438 0℃. The solvent separated in this process can be directly used as the solvent for making thick brain.
