The aim of this series of two publications is to characterise important radical reactions of organic molecules in atmospheric water phases, such as cloud, fog, and rain droplets, or on wetted aerosols. In this first study the reactions occurring in a mixed ...
The reaction of 4-methoxy-1,2,3,4-tetrahydroisoquinolines I (R = MeO, R1 = H; RR1 = OCH2O) with Li diisopropylamide affords dimerization products II. The intermediacy of orthoquinodimethanes and diradicals is assumed. [on SciFinder (R)] ...
Oscillation of the reaction rate, leading to strong, irregular oscillation of the conversion in dependence on the time, and sudden conversion changes occurred in certain temp. and concn. regions in the exptl. study of the catalytic hydrogenation of C2H4 wi ...
The aim of this study is to identify the reaction mechanism of methanol dehydrogenation on sodium carbonate catalyst. Quantitative analyses of the products of methanol dehydrogenation on sodium carbonate catalyst at 963 K indicate that methane is formed in ...
A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...
The first part of this laboratory study deals with heterogeneous reactions of bromine- and chlorine-containing species relevant to the atmosphere with solid model alkali salt substrates. The second part of this work treats the heterogeneous interaction of ...
The deactivation kinetics of a V/Ti oxide catalyst were studied in partial oxidn. of toluene to PhCHO and PhCO2H at 523-573 K. The catalyst consists of a monolayer of VOx species, and after oxidative pretreatment, contains isolated monomeric and polymeric ...
The polymn. of isoprene induced by alkyl lithium compds. in hydrocarbon solvents is known to proceed with a high stereoselectivity to (Z)-1,4-polyisoprene. We have studied the initiation step of this reaction with the help of ab initio mol. dynamics simula ...
Various catalysts were used in a systematical study of selective catechol methylation to 3-methylcatechol (I) in a fixed-bed reactor of 35-mm diam. and 16-cm length. Reaction products were analyzed by gas chromatog. with mass spectrometric detection. Alumi ...
The effect of forced concn. oscillations on a catalytic reaction with stop-effect was studied based on 2 different adsorption-desorption models. Both models predict mean reaction rates which can be more than twice as high as the max. rate under optimum ste ...
