Jacketed Reaction Vessel

Description

Jacketed Reaction Vessel also called a jacketed reactor or double-walled reactor is a specialized piece of laboratory or industrial equipment designed for chemical reactions that require precise temperature control. It consists of an inner vessel where the reactants are held and mixed, surrounded by an outer jacket through which a heat transfer fluid (such as water, oil, or a coolant) circulates to heat or cool the reaction. This setup allows for efficient thermal regulation, preventing heat loss or gain from the environment and enabling reactions to occur under controlled conditions, often ranging from -120°C to 250°C depending on the model.

Jacketed Vessels are usually constructed from borosilicate glass for lab use due to its thermal shock resistance and transparency, though stainless steel versions exist for larger industrial scales. Sizes range from small benchtop models (e.g., 100 mL to 5 L) for R&D to pilot-scale (up to 50 L or 200 L) for process development.

Key Features of Jacketed Reaction Vessel

Inner Vessel: Typically made of borosilicate glass for chemical resistance and visibility. It holds the reactants and supports stirring or mixing.

Outer Jacket: Circulates the temperature-regulating fluid. Single-jacketed vessels are common for basic heating/cooling, while double-jacketed versions provide better insulation for extreme temperatures, reducing energy use and keeping the vessel ice-free at low temps.

Accessories: Often includes a variable-speed stirrer (PTFE-coated), temperature probe with digital display, feeding funnel, condenser, and bottom discharge valve for sampling or product removal. The system can operate under vacuum or pressure for batch or continuous processes.

The vessel works by transferring heat through the jacket walls to the inner reaction space. For example, hot fluid in the jacket raises the temperature for exothermic reactions, while cold fluid cools for endothermic ones. This indirect method ensures safety and uniformity.

FAQ for Jacketed Reaction Vessel

What is a Jacketed Reaction Vessel?

A Jacketed Reaction Vessel (also known as Jacketed Reactor or Double-Walled Reactor) is a specialized piece of equipment used for chemical reactions that require precise temperature control. It consists of an inner vessel for holding and mixing reactants, surrounded by an outer jacket through which heating or cooling fluids (water, oil, steam, or coolant) circulate. This design enables efficient thermal regulation, typically ranging from -120°C to 250°C, while preventing heat loss to the environment.

How does the Jacketed Reaction Vessel work?

The vessel works by transferring heat through the jacket walls to the inner reaction space. A heat transfer fluid circulates in the jacket (or limpet coil) to heat or cool the contents. An agitator ensures homogeneous mixing. The system supports operations under vacuum or pressure and can handle batch or continuous processes. Accessories like temperature probes, condensers, and discharge valves provide full process control.
