New Device Measures Atmospheric Isocyanic Acid

چکیده
PA Rule Targets Smokestack Pollution In July 2011 the U.S. EPA finalized the CrossState Air Pollution Rule to reduce SO2 and NOX emissions from power plants using available emissions control technologies. SO2 and NOX contribute to ground-level ozone and fine particle pollution and often cross state lines, ending up far from their provenance. The rule is projected to achieve up to $280 billion in annual health benefits by preventing avoidable illnesses, sick days at work, and premature deaths. Within three years the rule is expected to help reduce SO2 emissions by 73% and NOX emissions by 54% over 2005 levels.

HPCO—A Phosphorus‐Containing Analogue of Isocyanic Acid
We describe the isolation and spectroscopic characterization of the heavier phosphorus-containing analogue of isocyanic acid (HPCO), and its isotopologue (DPCO). This fundamental small molecule, which has been postulated to exist in interstellar space, has thus far only been observed at low gas phase concentrations or in inert gas matrices. In this report we describe its synthesis, spectroscopi...
متن کاملMolecular Structure of Isocyanic Acid, HNCO, the Imide of Carbon Dioxide.
Isocyanic acid, HNCO, the imide of carbon dioxide, was prepared by reaction of stearic acid and potassium cyanate (KOCN) at 60 °C in a sealed, thoroughly dried reactor. Interestingly, its crystal structure, solved by X-ray single crystal diffraction at 123(2) K, shows a group-subgroup relation for the NCO- anion to carbon dioxide: (for CO2, cP12, Pa3̅, a = 5.624(2) Å, 150 K, C-O 1.151(2) Å; for ...
متن کاملSynthesis, Properties and Dimerization Study of Isocyanic Acid
In an 1830 publication J. Liebig and F. Wöhler [1] first reported on the preparation of isocyanic acid, which later was improved by A. Baeyer [2]. The preparation and properties of HNCO and some of its derivatives have been described in the literature [3, 4]. The polymerization of HNCO leads to a mixture of cyanuric acid (trimer of HNCO) and cyamelide [3, 5]. Cyanuric acid is a commercially ava...
متن کاملContribution of post-harvest agricultural paddy residue fires in the N.W. Indo-Gangetic Plain to ambient carcinogenic benzenoids, toxic isocyanic acid and carbon monoxide.
In the north west Indo-Gangetic Plain (N.W.IGP), large scale post-harvest paddy residue fires occur every year during the months of October-November. This anthropogenic perturbation causes contamination of the atmospheric environment with adverse impacts on regional air quality posing health risks for the population exposed to high concentrations of carcinogens such as benzene and toxic VOCs su...
متن کاملInfrared spectrum of solid isocyanic acid (HNCO): vibrational assignments and integrated band intensities.
Infrared spectra of thin films of solid HNCO condensed from the gas phase are characterized in terms of their vibrational frequencies, mode assignments, and integrated band intensities at low temperatures ( approximately 20-145 K). Isocyanic acid is shown to react with water (H2O) and ammonia (NH3) even at low temperatures; consequently, it may be an important species in the chemistry of inters...
