Among the substituents tested at the 2-position, the m-phenoxybenzyl group showed optimum selectivity and potency at the hP2X3 receptor.
Ethane to oxygen ratio C2H6/O2=2 and feed composition of 10%C2H6/5%% O2 were selected as the best trade-off between optimum selectivity and acceptable ethane conversion level.
It was shown that optimum selectivity with the maximal isomer yield was obtained for the catalyst where calcination and Pt acid decomposition were hold simultaneously at high temperature.
The K2CO3 promoted catalyst has an optimum selectivity to higher alcohols at 280 °C; addition of Mn made the catalyst more selective towards methanol.
Results suggest that CuCr0.5Mn1.5O4-based coatings are more favorable than CuCrMnO4-based ones and coatings using 700 °C calcined CuCr0.5Mn1.5O4 as pigment exhibit the optimum spectral selectivity (αs=0.92∼0.93, εT=0.22∼0.31).
The D/M/D multilayer film with Mo(t) = 20 nm, where the nano-columnar morphology of the D-M-D layers are aligned perpendicular to the substrate surface and exhibits the optimum spectral selectivity.
The optimum C5+ selectivity of 70.2% was attained at 7.6 vol% of O2, 208.9 ml/min of total feed flow rate, and 3.2 wt% of W content with the corresponding methane conversion of 26.7%.
Optimum selectivity was observed at low contact times and temperatures below 500C.
HRMS offers both good sensitivity and optimum selectivity.
