Embodiment 1
[0033] Embodiment 1: a kind of preparation technology of α-amyresin alcohol fine particle, use existing supercritical fluid anti-solvent equipment, it is characterized in that it is made of following steps:
[0034] (1) Configure α-amyresin liquid: control the system pressure of the equipment to 12Mpa, the melting temperature to 45°C, the spray distance to 10cm, and the nozzle temperature to 45°C. After the indicators are stable, inject 60ml of α-amyresinol solution with a flow rate of 1ml / min;
[0035] Dissolve the 0.5% α-amyl alcohol solution 1 in ethanol, and input it into the equipment system through the high performance liquid chromatography solution pump 2; the dissolution temperature is 40°C, and the equipment system pressure is 12MPa;
[0036] Entrainer 10-1 is absolute ethanol, and the flow rate is 20ml / min;
[0037] (2) Carbon dioxide feed: the CO in the steel cylinder 2 9 Enter the supercritical fluid anti-solvent equipment system into the crystallization kettle...
Embodiment 2
[0041] Embodiment 2: a kind of preparation technology of α-amyresin alcohol fine particle, use existing supercritical fluid anti-solvent equipment, it is characterized in that it is made of following steps:
[0042] (1) Configure α-amyresin liquid: control the system pressure of the equipment to 12Mpa, the melting temperature to 45°C, the spray distance to 10cm, and the nozzle temperature to 45°C. After the indicators are stable, inject 60ml of α-amyresinol solution with a flow rate of 1ml / min;
