Abstract

The invention discloses a novel process for purifying solanesol based on chemically modified diatomite, which comprises the following steps of: (1) grinding 3.0 g of diatomite into fine powder with the particle size of 500-800 meshes, adding 8-12ml of any strong acid except hydrofluoric acid into the fine powder to form a solution, filling the solution into a closed container I, putting the closed container I into a constant-temperature water bath, and heating the closed container I to 60-80 DEG C; the preparation method comprises the following steps: adding diatomite into a reaction kettle, shaking at normal temperature for 45-55 minutes, washing the shaken solution to be neutral, filtering by a screen with the aperture of 20-25 microns, and drying the obtained filtrate to constant weight to obtain modified diatomite; (2) 0.3-0.8 g of the modified diatomite obtained in the step (1) is added into 50 ml of an extract containing solanesol to form a mixed solution, the mixed solution is contained in a third closed container, the third closed container is placed in a constant-temperature water bath, oscillation is conducted for 45-55 min at the normal temperature, the oscillated mixed solution is filtered, filter residues are obtained, and the aperture of a mesh screen for filtering is 10-15 microns; (3) washing the filter residues with washing liquor to obtain solanesol, wherein the washing liquor is a solanesol-soluble solution; the process can greatly reduce the separation cost.

Description

technical field [0001] The invention relates to a separation and purification technology of solanesol in tobacco extract, a new process for purifying solanesol based on chemically modified diatomite. Background technique [0002] Diatomaceous earth is a biogenic siliceous sedimentary rock composed mainly of microalgae such as diatoms tens of thousands of years ago. These diatoms are single-celled microalgae, usually only 10 to tens of microns in shape. The density of diatomite is 1.9-2.35 g / cm3, the bulk density is 0.34-0.56 g / cm3, the specific surface area is 10-60 m2 / g, the pore volume is 0.46-0.98 cm3 / g, and the melting point is 1650°C-1750°C . The special porous structure of diatomaceous earth can be observed under the electron microscope (such as figure 1 shown). The micropores of its shell are generally tens of nanometers to several micrometers, with loose texture, high porosity and strong adsorption capacity. [0003] Diatomaceous earth is chemically stable and w...
