Flux estimates of isoprene, methanol and acetone from airborne PTR-MS measurements over the tropical rainforest during the GABRIEL 2005 campaign
Flux estimates isoprene methanol airborne PTR-MS tropical rainforest
2009/7/15
Tropical forests are a strong source of biogenic volatile organic compounds (BVOCs) to the atmosphere which can potentially impact the atmospheric oxidation capacity. Here we present airborne and grou...
On the relationship between acetone and carbon monoxide in different air masses
acetone carbon monoxide different air masses
2009/3/11
Carbon monoxide and acetone measurements are presented for five aircraft measurement campaigns at mid-latitudes, polar and tropical regions in the northern hemisphere. Throughout all campaigns, free t...
Sources and sinks of acetone, methanol, and acetaldehyde in North Atlantic marine air
sinks acetone methanol acetaldehyde North Atlantic marine air
2009/2/12
Measurements of acetone, methanol, acetaldehyde and a range of non-methane hydrocarbons have been made in North Atlantic marine air at the Mace Head observatory. Under maritime conditions the combina...
Oxygenated compounds in aged biomass burning plumes over the Eastern Mediterranean: evidence for strong secondary production of methanol and acetone
Oxygenated compounds Eastern Mediterranean methanol acetone
2009/1/23
Airborne measurements of acetone, methanol, PAN, acetonitrile (by Proton Transfer Reaction Mass Spectrometry), and CO (by Tunable Diode Laser Absorption Spectroscopy) have been performed during the Me...
Air-sea fluxes of methanol, acetone, acetaldehyde, isoprene and DMS from a Norwegian fjord following a phytoplankton bloom in a mesocosm experiment

The ocean's influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood. This work characterises the oceanic emission and/or uptake of methanol, acetone, acetaldehyde, isopre...
Synthesis and Characterization of New Material——La/Zr/MMT Employed in Acetone Oxidation
锆交联 蒙脱土 稀土镧掺杂 丙酮氧化
2007/12/20
摘要 蒙脱土作为一种新型催化材料, 越来越受到人们的重视。目前对锆交联的层状蒙脱土已有很多研究，但采用稀土元素掺杂锆制备交联蒙脱土并用于VOCs氧化方面的研究鲜有报导。本文合成了稀土镧掺杂锆复合的交联蒙脱土新材料，采用XRD, TEM, TG-DTA和BET等分析手段对合成的样品进行了表征。结果表明，经镧掺杂锆柱撑以后，蒙脱土层间距由1.57增加到4.85nm，与单一的锆柱撑的蒙脱土相比较，该材料...

The Kinetic Study of the Chemical Oscillating System of 1,3-Propanediol/Acetone as the Organic Substrate
Oscillation 1,3-propanediol Acetone Mixed substrates
2010/4/21
This work was primarily an experimental investigation of the bromate oscillator using 1,3-propanediol and acetone as the mixed organic substrates. The empirical equation of the induction period and os...
The Effect of Acetone on Calomel Formation on a Mercury Film Electrode Surface in Chloride Medium
The Effect of Acetone Calomel Formation Mercury Film Electrode Surface Chloride Medium
2010/6/27
In the presence of chloride ions, calomel formation takes place on the mercury thin film electrodes under open-circuit conditions, which leads to high base currents and erratic performance in ASV meas...
The Effectof Temperature on the Dynmaic Viscosity of Acetone Sunflower-Seed Oil Mixtures
Acetone/oil solution density modelling sunflower-seed oil temperature effect viscosity
2010/6/30
The effect of acetone on the dynamic viscosity of sunflower-seed oil was studied under a dynamic heating regime at temeparuters ranging from 25oC to 50oC at 5oC intervals. Acetone dramatically reduced...
