Photochemical Generation and Spectroscopic Characterization of Parent 3‐Iminooxetane and 3‐Oxazoline From 3‐Azidooxetane

Chemistry – A European Journal, EarlyView.
Two previously uncharacterized heterocyclic imines, 3‐iminooxetane and 3‐oxazoline, are generated simultaneously by irradiation of 3‐azidooxetane under matrix isolation conditions. The infrared spectra provide reference data for future gas‐phase studies and may facilitate their search in the interstellar medium.

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

Chemie Ingenieur Technik, EarlyView.
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.

Purity Determination of Acetaldehyde in an Acetaldehyde Certified Reference Material

Analytical Sciences, 2015
Acetaldehyde is regulated as a toxic substance in various fields, and the method for monitoring or analysis of acetaldehyde is important. However, handling is difficult because of the high reactivity and low boiling point of acetaldehyde. Therefore, a reference material for high purity acetaldehyde with high accuracy was not available.
