Dong and Zhiwei Chen, Department of Chemistry, University of California, Irvine, CA This experiment will demonstrate the hydrogenation of chalcone as an example of an alkene hydrogenation reaction (Figure 1). In this experiment, palladium on carbon (Pd/C) will be used as a heterogeneous catalyst for the process. A balloon will be used to supply the hydrogen atmosphere.

Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide. Asymmetrical sulfides can be synthesized by treating thiols with an alkyl halide and a...

Structure and Nomenclature of Thiols and Sulfides

Thiols and sulfides are sulfur analogs of alcohols and ethers, respectively, where the sulfur atom takes the place of the oxygen atom. Thus, thiols are generally represented as RSH, where R is an alkyl substituent and —SH is the functional group. On the other hand, in sulfides, the central sulfur atom is bonded to two hydrocarbon groups on either side. Depending upon the type of group, sulfides can be either symmetrical or asymmetrical. Both thiols and sulfides display a bent geometry, similar...

Gas-absorption designs transfer H₂S from the gas stream into a liquid, while reactive-media designs capture it on a material that promotes chemical or biological conversion. This distinction determines where sulfide is retained and how it is transformed. Both approaches can reduce airborne H₂S, but their operating principles suit different air or process-stream treatment needs.
Capture alone does not describe the full treatment outcome. In a scrubber, chemical or biological reactions convert sulfide into less hazardous products after transfer to a liquid or capture by a reactive medium. These reactions help reduce the hazards associated with H₂S while supporting safer handling of streams generated by biological production systems.
Removing H₂S addresses several linked problems rather than odor alone. Because the gas is toxic, corrosive, and foul-smelling, effective treatment can protect personnel, reduce nuisance odors, and limit corrosion of surrounding equipment. These effects make scrubbing relevant wherever biological processes generate gas streams that could expose workers or damage infrastructure.
The contaminated air or process stream first contacts either a liquid or a reactive medium, depending on the scrubber design. H₂S then transfers into the liquid or becomes captured on the medium, where chemical or biological reactions convert sulfide into less hazardous products. The treated stream consequently leaves with reduced H₂S-related hazards.
Bioengineering applications include anaerobic digestion, wastewater treatment, and bioprocessing facilities. In each setting, biological activity can generate process streams containing H₂S, making emission control part of facility operation. Scrubbing helps these systems manage toxic and corrosive gas exposure while also addressing odor and the environmental consequences of biological production.
A properly applied system can provide several operational and environmental benefits at once. Lower H₂S emissions help protect personnel, reduce odor, and limit corrosion, while also supporting regulatory compliance. In facilities based on anaerobic digestion, wastewater treatment, or bioprocessing, this control can contribute to improved environmental performance of the broader biological production system.
