Embodiment 1
[0024] (1) Add 60g of propionic acid and 10g of testosterone into the reaction bottle, stir well, add 3g of propionyl chloride, heat up to reflux for 3 hours, monitor by TLC, the reaction is complete; add 600g of water into the beaker, stir the reaction solution in the reaction bottle slowly Add dropwise into water, stir evenly, filter with suction, wash the material with 200g of water until the pH is 6, drain and discharge the material, dry to obtain 11.7g of testosterone propionate crude product, and collect a total of 850g of waste acid water at the same time;
[0025] (2) Add 117g of methanol, 0.351g of activated carbon, and 11.7g of crude testosterone propionate into the reaction flask, heat up and reflux for decolorization for 1 hour, filter with suction, concentrate the filtrate to the remaining 11.7g of methanol, cool down to 5°C, stir and crystallize for 4 hours, and vacuum filter , drained and discharged, dried at 60°C to constant weight to obtain 11.3g of testosteron...
Embodiment 2
[0028] (1) Add 80g of propionic acid and 10g of testosterone into the reaction bottle, stir well, add 5g of propionyl chloride, heat up to reflux for 2 hours, monitor by TLC, the reaction is complete; add 800g of water into the beaker, stir the reaction solution in the reaction bottle slowly Add dropwise into water, stir evenly, filter with suction, wash the material with 300g of water until the pH is 7, drain and discharge the material, and dry to obtain 11.5g of testosterone propionate crude product, while collecting a total of 1170g of waste acid water;
[0029] (2) Add 138g of methanol, 0.575g of activated carbon, and 11.5g of crude testosterone propionate into the reaction flask, heat up and reflux for decolorization for 0.5h, filter with suction, concentrate the filtrate to the remaining 17.25g of methanol, cool down to 0°C, stir and crystallize for 2h, filter , drained and discharged, dried at 65°C to constant weight to obtain 11.2g of testosterone propionate with a puri...
