Direct In Situ Quantifiion of HO2 from a Flow Reactor

2013-2-27 · The first direct in situ measurements of hydroperoxyl radical (HO2) at atmospheric pressure from the exit of a laminar flow reactor have been carried out using mid-infrared Faraday rotation spectroscopy. HO2 was generated by oxidation of dimethyl ether, a potential renewable biofuel with a simple molecular structure but rich low-temperature oxidation chemistry.

Supersaturation is important because it is the driving force for both crystal nucleation and growth. The control of supersaturation is key to attaining desired product attributes, especially final crystal size distribution and phase. Generally speaking, at low supersaturation, crystals can grow faster than they nucleate, resulting in a larger
