Homemade Stearic Acid
The method of self-made stearic acid
If you want to get self-made stearic acid, you need to understand the method. Take all the things first, the necessary oil, this is the basis. For oils, animal and vegetable oils can be used, but the quality is better.
Add the oil into the kettle and add an appropriate amount of alkali. For alkalis, it is appropriate to use caustic alkalis, such as sodium hydroxide. Cook slowly over a slow heat, stirring frequently to ensure uniformity. During this process, the oil reacts with the alkali in a saponification reaction.
After the saponification is completed, add acid. Sulfuric acid is the appropriate acid, add it slowly, and observe its changes. At this time, stearate reacts with acid, and stearic acid gradually emerges.
Wait for stearic acid to precipitate, filter it with a filter to remove its impurities. Then wash it with water to remove its residual acid and alkali. After drying, pure self-made stearic acid can be obtained.
To make this acid, it is related to the temperature and dosage, and it must be accurate. If it is slightly worse, the quality will be different. Only with care can we get good products for our needs.
