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.

Abstract
The preparation method and the application of the water-soluble compound of d-borneol belong to the technical field of chemical industry. The preparation method comprises: 1) adding sodium or potassium to the ether or alcohol solution of d-borneol under a nitrogen atmosphere, stirring slowly to fully react, leaving it to stand overnight; 2) filtering and concentrating the mixture obtained in step 1) , washing, drying, and collecting the solid; 3) dissolving the solid obtained in step 2) in water, dialysis with an osmotic membrane, and then removing water under reduced pressure to obtain a water-soluble sodium or potassium salt of d-borneol. The present invention makes dextroborneol water-soluble sodium salt or potassium salt of dextroborneol, that is, natural borneol, through the step conditions of the present invention, changes the characteristics of dextroborneol insoluble in water, and the obtained product is very easily soluble in water. Water brings convenience for subsequent processing. In addition, the present invention develops a new application of the water-soluble sodium or potassium salt of d-borneol.
Description
technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of a water-soluble compound of d-borneol and an application thereof. Background technique [0002] Cirmamonun Camphora is not only a precious and rare medicinal material, but also a high-grade spice, and an important chemical raw material. Known as plant gold, borneol camphor is native to the natural dipterocarp tree roots in Sumatra, Indonesia. It used to be the main source of borneol, but it has been nearly exhausted due to long-term over-harvesting. Borneo was first recorded in the Southern and Northern Dynasties, and has a history of more than two thousand years. In the classics of traditional Chinese medicine, borneol is called natural borneol. Because of its transdermal function, it is classified as an aromatic medicinal material. "Book of Materia Medica" says: borneol "its fragrance is the crown of a hundred medicines.". [0003...
