A pressure reactor, also known as a pressure tube or sealed tube, is a specialized chemical reaction vessel designed to perform reactions under high pressure conditions. It is a type of pressure vessel, uniquely designed to withstand high-pressure environments. The pressure within the reactor can arise either from the reaction itself or an external source, such as the use of hydrogen in catalytic transfer hydrogenation.

Advantages
A pressure reactor has advantages over a round-bottom flask. It allows reactions above solvent boiling points and reduces reaction volume to increase concentration, collision frequency, and accelerate reactions.
Pressure accelerates desired reactions and minimizes competing reactions, without impacting decomposition unless involving gas.
A pressure reactor can satisfy four green chemistry principles by using less solvent and producing cleaner profiles, saving electricity and water, and preventing gas release and explosions.
Metal pressure reactors
Metal pressure reactors are highly advantageous for conducting high-pressure reactions, as they possess a much higher pressure rating than glass reactors. Despite having their own distinct flaws, such as susceptibility to corrosion, the correct material of construction (MOC) can reduce or even eliminate vessel corrosion during the design phase of a metal pressure reactor. While the cost of the system may increase depending on the material chosen, the benefits of using a metal pressure reactor outweigh the costs. Additionally, metal vessels are sturdier than glass and can withstand higher pressure levels without the risk of shattering.
Metal high-pressure reactors are versatile and have extensive applications in various reactions, including but not limited to hydrogenation, polymerization, synthesis, catalytic, and petrochemical reactions. Moreover, they find extensive use in research, such as upstream, biomass, biopolymer, zeolite studies, and other fields. The use of metal pressure reactors enables scientists to perform experiments at higher pressure levels, which can lead to faster reactions, cleaner products, and more efficient processes.

FAQ
What is a high pressure reactor?
A high-pressure reactor is an equipment designed to perform chemical reactions or other processes under elevated pressure and temperature conditions. It is used in various industries, such as chemical, petrochemical, pharmaceutical, and materials science, to carry out processes requiring high pressure or temperatures. It includes a pressure vessel, closure, temperature, and pressure control, stirring or mixing mechanism, and ports or connections. High-pressure reactors are useful in studying reaction kinetics, performing catalytic reactions, synthesizing new materials, and developing novel chemical processes. They come in various sizes and designs, with temperature control and agitation options, making them suitable for a wide range of reactions.
What causes an increase in pressure within a high-pressure reactor?
Increasing pressure inside a pressure reactor can be achieved through various means. One common method is by heating a sealed pressure vessel, where temperature and pressure increase proportionately, impacting reaction kinetics. Alternatively, the reaction occurring inside the vessel can induce pressure, and agitation can accelerate this process.
In situations where heating is unsuitable or insufficient pressure is generated, manual pressurization is possible with a compressed gas source, such as a compressor or a pre-compressed canister of inert gas.
Pressure reactors utilize pressure relief valves to safely regulate and maintain pressure, emphasizing their reliable and safe operation.
How does a pressure reactor work?
A pressure reactor is a laboratory device used to conduct chemical reactions at high pressure. It works by controlling the pressure within the reactor vessel, allowing researchers to increase the pressure to desired levels and monitor the reaction as it occurs. The high-pressure environment can alter the reaction rate and outcome, making pressure reactors an essential tool for understanding the underlying mechanisms of chemical reactions. Pressure reactors are designed with safety in mind, featuring high-quality pressure-resistant materials, automatic pressure control systems, and leak-detection systems. They come in various sizes and designs, making them suitable for a wide range of reactions.
