| titleOfInvention | A kind of new technology of borneolum syntheticum crystalline sheet borneol |
| abstract | The present invention relates to a kind of new technology of borneolum syntheticum crystalline sheet borneol, its step comprises, 1) and the broken step of material; 2) the molten clear step of material: the organic solvent for dissolving borneolum syntheticum is mixed with borneolum syntheticum, and its weight ratio is 0.9～20:1 stirs until borneolum syntheticum dissolves under the condition of heating; 3) gradient temperature control is separated out step: the material of dissolving is progressively cooled to 50～120 DEG C of the first Precipitation Temperatures; Be cooled to 40～80 DEG C of the second Precipitation Temperatures with the speed of 0.05～2 DEG C/h afterwards; 4) decrease temperature crystalline step: be cooled to room temperature or carry out frozen cooling to-5～-15 DEG C with the speed of 0.2～5 DEG C/h with 0.05～2 DEG C/h speed; Some days of crystallization, in material, sheet borneolum syntheticum is separated out, and drying obtains borneolum syntheticum sheet finished product. This invention has overcome the low shortcoming of existing borneolum syntheticum crystallization processes sheet borneol yield, can effectively improve the sheet borneol output of borneolum syntheticum crude product. |
