Properties of polar stratospheric clouds obtained by combined ACE-FTS and ACE-Imager extinction measurements

International audienceWe report the compositions and size distributions of aerosol particles in typical polar stratospheric clouds (PSCs) observed between 24 January and 28 February 2005 in the Arctic stratosphere. The results are obtained by combining the extinction measurements made by the Atmospheric Chemistry Experiment (ACE) Fourier-Transform Spectrometer and the visible/near IR imagers on the SCISAT satellite. The extended wavenumber range provided by this combination (750 to 20 000 cm?1) enables the retrieval of aerosol particle sizes between 0.05 and 10 ?m as well as providing extensive information about the compositions. Our results indicate that liquid ternary solutions with a high (>30 wt%) content of HNO3 were the most probable component of the clouds at the (60?70° N) latitudes accessible by ACE. The mean size of these ternary aerosol particles is in the range of 0.3 to 0.8 ?m. Less abundant, although still frequent, were clouds composed of NAT particles having radii in the range of 1 ?m and clouds of ice particles having mean radii in the 4?5 ?m range. In some cases, these last two types were found in the same observation

Reactions of vinylphosphonates with piperazines

© 2017, Pleiades Publishing, Ltd. Dialkyl [2-(piperazin-1-yl)ethyl]phosphonates were obtained by the reactions of piperazine with dialkyl vinylphosphonates. The addition of 2-(piperazin-1-yl)ethanamine to diethyl vinylphosphonate involves the primary exocyclic amino group of the heterocyclic compound

Kinetics and Mechanism of the Kabachnik-Fields Reaction: V. Effect of the Nature of the Hydrophosphoryl Compound on the Mechanism of the Kabachnik-Fields Reaction

Replacement of dialkyl hydrogen phosphites by phosphonites and phosphinites affects the rate and mechanism of the Kabachnik-Fields reaction or even changes the mechanism to alternative. The nature of the hydrophosphoryl compound most strongly affects the structure of its prereaction complex with the amine, by endowing the complex with polarization favoring one or the other route, and also the rate of formation and thermodynamic stability of the corresponding hydroxyphosphonates (phosphinates, phosphine oxides) which are key intermediates of one of the possible reaction routes

Properties of coatings based on carbon and nitrogen-doped carbon obtained using a pulsed vacuum arc method

Diamond-like carbon coatings on hard-alloy substrates, including coatings doped with nitrogen about 1.0 μm thick have been obtained using a pulse vacuum-arc method. Three types of coatings have been investigated: a carbon diamond-like coating (C), a carbon coating doped with nitrogen (C : N), and a composite coating based on (C : N + C) layer

Synthesis, structure, and biologic activity of products of reactions between dinitrodichlorobenzofuroxane and aminopyrimidines in aqueous dimethyl sulfoxide

© 2016, Pleiades Publishing, Ltd.Reactions of 4,6-dinitro-5,7-dichlorobenzofuroxane with substituted pyrimidines in aqueous DMSO proceed through an intermediate formation of 5-hydroxy-4,6-dinitro-7-chlorobenzofuroxane owing to the hydrolysis of one of the chlorine atoms with the subsequent formation of pyrimidine salts exhibiting a high biologic action

Synthesis of carboxylate arsenobetaines based on (carboxyalkyl)triphenylarsonium halides

© 2015 Pleiades Publishing, Ltd. It has been found that the reaction of triphenylarsine with unsaturated carboxylic acids (acrylic, maleic, and itaconic ones) supposed to yield the arsenobetaines does not occur, in contrast to similar reactions of carboxylic acids with tertiary phosphines. However, the interaction of tertiary arsines with the halogenated carboxylic acids has resulted in the corresponding tertiary arsonium salts, dehydrohalogenation of the latter affording the target carboxylate betaines in the quantitative yield; the products structure has been elucidated using a set of chemical, physical, and physico-chemical methods. Antibacterial activity of the prepared compounds has been studied

Kinetics and Mechanism of the Kabachnik-Fields Reaction:. III. Effect of the Nature of the Carbonyl Compound on the Kinetics and Mechanism of the Kabachnik-Fields Reaction. a Unified Reaction Mechanism

The Kabachnik-Fields reaction in the series of substituted benzaldehydes can occur, depending on the nature of the carbonyl compound, via imine or hydroxyphosphonate formation. A unified reaction mechanism is proposed, involving both possible routes
