Embodiment 1
[0016] A production process of cholesterol, specifically comprising the following steps:
[0017] 1) Put the animal fat into the reactor, heat the animal fat with steam, add a solvent and an acidic catalyst to it, and adjust the pH value to 2.8;
[0018] 2) Add liquid caustic soda into the reaction kettle, adjust the pH value to less than 10, react for 3 hours, shut down, neutralize, wash with water at 90°C, and then separate;
[0019] 3) stirring and cooling to crystallize;
[0020] 4) Use a centrifuge to separate solids and liquids;
[0021] 5) refining the crude product, dissolving the mixed solution at a ratio of 1:20, adding 3% activated carbon, refluxing and filtering with heat preservation;
[0022] 6) The liquid is stirred and crystallized;
[0023] 7) After filtering and drying at 70°C, cholesterol with a purity of 90%-97% and a melting point of 145-148°C is obtained.
Embodiment 2
[0025] A production process of cholesterol, specifically comprising the following steps:
[0026] 1) Put the animal fat into the reaction kettle, heat the animal fat with steam, then add solvent and acid catalyst to it, and adjust the pH value to 3;
[0027] 2) Add liquid caustic soda into the reaction kettle, adjust the pH value to less than 10, react for 3 hours, shut down, neutralize, wash with water at 90°C, and then separate;
[0028] 3) stirring and cooling to crystallize;
[0029] 4) Use a centrifuge to separate solids and liquids;
[0030] 5) refining the crude product, dissolving the mixed solution at a ratio of 1:20, adding 3% activated carbon, refluxing and filtering with heat preservation;
[0031] 6) The liquid is stirred and crystallized;
[0032] 7) After filtering and drying at 70°C, cholesterol with a purity of 90%-97% and a melting point of 145-148°C is obtained.
Embodiment 3
[0034] A production process of cholesterol, specifically comprising the following steps:
[0035] 1) Put the animal fat into the reaction kettle, heat the animal fat with steam, add a solvent and an acidic catalyst to it, and adjust the pH value to 3.2;
[0036] 2) Add liquid caustic soda into the reaction kettle, adjust the pH value to less than 10, react for 3 hours, shut down, neutralize, wash with water at 90°C, and then separate;
[0037] 3) stirring and cooling to crystallize;
[0038] 4) Use a centrifuge to separate solids and liquids;
[0039] 5) refining the crude product, dissolving the mixed solution at a ratio of 1:20, adding 3% activated carbon, refluxing and filtering with heat preservation;
[0040] 6) The liquid is stirred and crystallized;
[0041] 7) After filtering and drying at 70°C, cholesterol with a purity of 90%-97% and a melting point of 145-148°C is obtained.
