A jacketed reactor, also known as a jacketed vessel or jacketed container, is a type of vessel used in chemical and industrial processes for various purposes, including mixing, heating, cooling, and conducting reactions. It consists of a main vessel or container with an outer jacket that surrounds it. The jacket is typically filled with a heat transfer fluid, such as water, oil, or steam, which allows for precise temperature control of the contents inside the main vessel.Overall, jacketed reactors offer a high level of control, flexibility, and safety, making them a valuable tool in industries where precise temperature control and reaction control are essential.
