Circumstances requiring prior approval from the PI/Laboratory Supervisor must be addressed in laboratory-specific SOPs. These circumstances are based on the inherent hazards of the material being used, the hazards associated with the experimental process, the experience level of the worker, and the scale of the experiment. Some examples of circumstances that may require prior approval include working alone in a laboratory, unattended or overnight operations, the use of highly toxic gas of any amount, the use of large quantities of toxic or corrosive gases, the use of extremely reactive chemicals (e.g., pyrophorics, water reactive chemicals), or the use of carcinogens.
The dissociative chemisorption of methane on a metal catalyst is the rate limiting step in the steam reforming of natural gas, our primary source for the molecular hydrogen used in the Haber-Bosch process. In collaboration with the experimental group of Rainer Beck at the École Polytechnic Fédéral de Lausanne, we examined this reaction on a Pt surface containing step defects. We were able to differentiate between reactions at the step edges and the terrace sites, using both UHV molecular beam experiments and high-dimensional quantum scattering theory. Both approaches were also able to resolve the reaction probability with respect to the velocity and vibrational state of the methane molecule and the surface temperature, providing additional details about the reaction mechanism.
Synthesis Reactions (Description and Examples) - …
A method for the synthesis of ibuprofen in introductory organic chemistry laboratory courses is reported. This experiment requires two 3-h lab sessions. All of the reactions and techniques are a standard part of any introductory organic chemistry course. In the first lab session, students reduce -isobutylacetophenone to an alcohol and then convert this alcohol to the corresponding chloride. In the second session, students convert this chloride to a Grignard reagent, which is then carboxylated and protonated to give ibuprofen. Although the final yield is modest, this procedure offers both practicability and reliability. Permanent-magnet 60 MHz 1H NMR spectra of the final product and the two intermediates are clean and are easily interpreted by the students. Because, as previously reported, the benzylic methylene and the benzylic methine of ibuprofen have virtually identical 13C NMR chemical shifts and cancel or nearly cancel each other in the DEPT spectrum, this synthesis provides a fitting opportunity for the introduction of HETCOR even with a permanent-magnet Fourier transform instrument.
Also in the Flow area: with the multistep synthesis of 5-methyl-4-propylthiophene-2-carboxylic acid as our example, we’ve devised a single reactor platform to conduct both batch and flow reactions, either singly or in concert, using open source technologies to automate, control and monitor individual processes. See in React. Chem. Eng., 2016, 1, 629. We’ve also developed a modular software system that enables researchers to monitor and control chemical reactions via the Internet, using any device from any location in the world. See in Org. Process. Res. Dev. 2016, 20, 386. A few other bits and bobs: our and a virtual tour around our Flow Laboratory; – the IoCT which we define as the interconnection and networking of chemical machines, computing devices and all chemical services delivered through the infrastructure of the Internet is coming; – enabling researchers to rationalise and predict organic reactions using computational analysis in silico.

Be sure to count the number of atoms in both the reactants and products. Sometimes when a chemical equation is written, "extra" information is given that may make it hard to recognize what is going on in a reaction. Counting numbers and types of atoms makes it easier to identify reaction types.
