Embodiment 1
[0020] Embodiment 1: Preparation of the water-soluble sodium salt of d-borneol
[0021] 1) Under a nitrogen atmosphere, add sodium metal to the ethanol solution of d-borneol in the reaction vessel, the molar ratio of d-borneol to sodium metal is 1:1.1, and slowly stir at a temperature of 25°C for 35 minutes, Fully react, stand still, overnight;
[0022] 2) Concentrate the mixture obtained in step 1) by filtration, wash with ethanol, dry, and collect the solid;
[0023] 3) Dissolving the solid obtained in step 2) in water, and then using an osmotic membrane for dialysis for 5 days, and then removing water under reduced pressure to obtain a water-soluble sodium salt of d-borneol.
Embodiment 2
[0024] Embodiment 2: Preparation of the water-soluble potassium salt of d-borneol
[0025] 1) Under a nitrogen atmosphere, add metal potassium to the tetrahydrofuran solution of d-borneol in a reaction vessel, the molar ratio of d-borneol to sodium metal is 1:1.2, and slowly stir at a temperature of 24°C for 30 minutes, Fully react, stand still, overnight;
[0026] 2) The mixture obtained in step 1) was concentrated by filtration, washed with ether, dried, and the solid was collected;
[0027] 3) Dissolving the solid obtained in step 2) in water, and then using an osmotic membrane for dialysis for 3 days, and then removing water under reduced pressure to obtain a water-soluble potassium salt of d-borneol.
Embodiment 3
[0028] Embodiment 3: Preparation of the water-soluble sodium salt of d-borneol
[0029] 1) Under a nitrogen atmosphere, add metallic sodium to the ether solution of d-borneol, the molar ratio of d-borneol to metallic sodium is 1:1.3, and slowly stir at a temperature of 28°C for 40 minutes to fully react and statically place overnight;
[0030] 2) The mixture obtained in step 1) was concentrated by filtration, washed with ether, dried, and the solid was collected;
[0031] 3) Dissolving the solid obtained in step 2) in water, and then dialysis with an osmotic membrane for 6 days, and then removing water under reduced pressure to obtain a water-soluble sodium salt of d-borneol.
