[0002] Quaternary ammonium lanolate is a surfactant widely used in detergents, softeners, and antimicrobial agents. To ensure the quality and yield of quaternary ammonium lanolate, precise control of reaction conditions is required during its production.

[0003] Traditional reactors mostly use jacket heating or cooling to regulate reaction temperature. The drawback of this method is that heat is indirectly exchanged between the jacket and the reaction liquid within the reactor through the reactor body. However, the reactor body has a low heat transfer coefficient, resulting in slow heat conduction and an inefficient temperature response of the reactor liquid. Furthermore, the energy utilization rate of the heating or cooling medium within the jacket is low, making it difficult to achieve uniform heating or cooling of the reactor liquid. This often leads to large temperature gradients within the reactor liquid, which in turn affects the precise control of reaction conditions. Utility Model Content
