Short summary
We have measured the evaporation rates of butenedial, a four-carbon dialdehyde produced in the atmosphere, from individual levitated particles. Effective vapor pressures and Henry's law constants, which characterize the compound's gas-particle partitioning behavior, were determined. The important role of hydration reactions was observed under both dry and humid conditions, as well as a salting-out effect in the presence of sodium chloride or sodium sulfate.
