Embodiment 1
[0022] Such as Figure 1-3 Shown, a kind of new technology of purifying solanesol based on chemically modified diatomite comprises the steps:
[0023] (1) Use a grinding bottle to grind 3.0g of diatomite into a fine powder with a particle size of 500 mesh, add 12ml of sulfuric acid with a concentration of 3mol / L to the fine powder to form a solution, and then place the grinding bottle containing the solution in a constant temperature water bath In the oscillator, shake at room temperature for 45 minutes, wash the shaken solution to neutrality, then filter through a sieve with a pore size of 20-25 μm, and dry the obtained filtrate to constant weight to obtain modified diatomite;
[0024] (2) Add 0.3g of modified diatomite obtained in step (1) to 50ml of solanesol-containing extract to form a mixed solution, put the mixed solution in an airtight container 3, and place the airtight container 3 in a constant temperature water bath for oscillation In the container, shake at room t...
Embodiment 2
[0027] Such as Figure 1-3 Shown, a kind of new technology of purifying solanesol based on chemically modified diatomite comprises the steps:
[0028] (1) Use a grinding bottle to grind 3.0g of diatomite into a fine powder with a particle size of 800 mesh, add 8ml of nitric acid with a concentration of 3mol / L to the fine powder to form a solution, and then place the grinding bottle containing the solution in a constant temperature water bath In the oscillator, shake at room temperature for 55 minutes, wash the shaken solution to neutrality, then filter through a sieve with a pore size of 20-25 μm, and dry the obtained filtrate to constant weight to obtain modified diatomite;
[0029] (2) Add 0.8g of modified diatomite obtained in step (1) to 50ml of solanesol-containing extract to form a mixed solution, put the mixed solution in a closed container 3, and place the closed container 3 in a constant temperature water bath for oscillation In the container, shake at room temperatu...
Embodiment 3
[0032] Such as Figure 1-3 Shown, a kind of new technology of purifying solanesol based on chemically modified diatomite comprises the steps:
[0033] (1) Use a grinding bottle to grind 3.0g of diatomite into a fine powder with a particle size of 600 mesh, add 10ml of hydrochloric acid with a concentration of 3mol / L to the fine powder to form a solution, and then place the grinding bottle containing the solution in a constant temperature water bath In the oscillator, shake at room temperature for 50 minutes, wash the shaken solution to neutrality, then filter through a sieve with a pore size of 20-25 μm, and dry the obtained filtrate to constant weight to obtain modified diatomite;
[0034] (2) Add 0.5g of modified diatomite obtained in step (1) to 50ml of tobacco extract containing solanesol to form a mixed solution, put the mixed solution in a closed container 3, and place the closed container 3 in a constant temperature water bath In the oscillator, shake at room temperatu...
