Heneicosanoic - Reference Information
| Application | Twenty-one carbonic acid can be used as an anionic surfactant, such as preparing a surfactant cleaning fracturing fluid, including the following steps: 1) reacting an anionic surfactant with a strong base to obtain product A;2) reacting the product A with a cationic surfactant to obtain the surfactant cleaning fracturing fluid. In the preparation method, the anionic surfactant may be a long chain saturated or unsaturated fatty acid, specifically, it may be 22-13-enoic acid, twenty-one carbonic acid, dicaric acid, or dicaric acid. |
| biological activity | Heneicosanoic acid is a long-chain saturated fatty acid, widely found in animals and plants. |
