Examples
preparation example 1
[0062] Prepare compound fluocinolone acetate tincture as follows,
[0063] Add 790ml of ethanol to the liquid mixing tank, start the stirring paddle of the liquid mixing tank, add 50g of salicylic acid and stir to dissolve, then add 50ml of glycerin, resorcinol 100g, borneol 20g, stir and dissolve to obtain the first mixed solution. Make the first mixed solution pass through a water-absorbing column containing 200g of silica gel (the quality of silica gel is 23.35% of the mass of the first mixed solution), weigh 0.4g of fluocinolone acetate and dissolve it in 20ml dimethyl sulfoxide, and dissolve to obtain the second mixed solution. liquid. Add the second mixture to the first mixture passing through the absorbent column. Adjust to the specified amount with an appropriate amount of absolute ethanol, continue to stir, and obtain it.
preparation example 2
[0065] Prepare compound fluocinolone acetate tincture as follows,
[0066] Add 79L of ethanol to the liquid mixing tank, start the stirring paddle of the liquid mixing tank, add 5kg of salicylic acid and stir to dissolve, then add 5L of glycerin, 10kg of resorcinol, and 2kg of borneol successively, stir and dissolve to obtain the first mixed solution. Make the first mixed solution pass through a water-absorbing column containing 6kg molecular sieve (molecular sieve mass is 7.01% of the first mixed solution mass), then weigh 40 g of fluocinolone acetate and dissolve it in 2L dimethyl sulfoxide, and dissolve to obtain the second mixed solution . Add the second mixture to the first mixture passing through the absorbent column. Adjust to the specified amount with an appropriate amount of absolute ethanol, continue to stir, and obtain it.
preparation example 3
[0068] Prepare compound fluocinolone acetate tincture as follows,
[0069] Add 553L ethanol in the liquid mixing tank, start the liquid mixing tank stirring paddle, add 35kg salicylic acid and stir to dissolve, then add 35L glycerin, resorcinol 70kg, borneol 14kg successively, stir, dissolve, get the first mixed solution. Make the first mixed solution pass through the water absorption column containing 30kg fiber desiccant (the quality of fiber desiccant is 6.53% of the first mixed solution quality), then weigh fluocinolone acetate 0.28kg and be dissolved in 14L dimethyl sulfoxide, dissolve, Obtain the second mixture. Add the second mixture to the first mixture passing through the absorbent column. Adjust to the specified amount with an appropriate amount of absolute ethanol, continue to stir, and obtain it.
