Robert M Rioux, Pennsylvania State University, University Park, PA The use of gases in a synthetic chemistry laboratory is essential for carrying out a variety of highly facile and atom economical transformations. Reactions such as hydrogenation, oxidation, and amination require the use of gases like hydrogen, oxygen, and ammonia. Due to the poor solubility of these gases in typical reactant solutions, high pressures are necessary to achieve a meaningful reaction rate. Not only are these gases...

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Source: Alexander S Rattner and Kevin Rao Li Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA The objective of this experiment is to demonstrate the phenomenon of stability of floating vessels - the ability to self-right when rolled over to the side by some external force. Careful design of hull shapes and internal mass distribution enables seagoing vessels to be stable with low drafts (submerged depth of hull), improving vessel...

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Here we present a protocol for performing reactions in simple reaction vessels under low-to-moderate pressures of CO2. The reactions can be performed in a variety of vessels simply by administering the carbon dioxide in the form of dry ice, without the need for costly or elaborate equipment or set-ups.
FAQs
The vessel material must be matched to the chemicals it contains as well as the intended operating conditions. An unsuitable material can lose integrity when exposed to the process contents or conditions, increasing the possibility of failure. Compatibility assessment is therefore a central design and operating decision for laboratory vessels, reactors, and other chemical-processing equipment.
A relief device must be properly sized so it can release excess pressure before the vessel reaches a rupture-threatening condition. Oversight of sizing weakens the protection provided by the device, while appropriate sizing supports controlled pressure management. This safeguard is especially important in systems containing compressed gases or liquids under pressure.
Chemical incompatibility, uncontrolled pressure or temperature, corrosion, and physical damage can each undermine vessel integrity. These factors may also interact, making routine inspection and operating control important rather than relying on a single safeguard. Detecting corrosion or damage early helps prevent failures that could cause explosions, toxic releases, or burns.
A practical review begins by confirming that the vessel material suits the chemicals and operating conditions. The operator then verifies pressure and temperature controls, examines the vessel for corrosion or damage, and confirms that relief devices are correctly sized. Applying these checks together creates a more reliable safety process than treating any one measure as sufficient.
The same principles apply across several common chemical systems, including gas cylinders, autoclaves, reactors, and compressed-gas systems. Although these vessels serve different functions, each requires attention to materials, pressure, temperature, condition, and pressure relief. This broad applicability makes pressure vessel safety relevant in both laboratory operations and industrial processing.
In chemistry, these practices help control hazards associated with pressurized substances while supporting dependable operation of experimental and production equipment. Preventing vessel failure reduces the potential for explosions, toxic releases, and burns. At the same time, systematic inspection and operating control improve process reliability and help organizations meet applicable engineering and laboratory standards.
