Title: Aromatic ring generation as a dust precursor in acetylene discharges

Abstract

Production of aromatic hydrocarbon compounds as an intermediate step for particle formation in low-pressure acetylene discharges is investigated via a kinetic approach. The detailed chemical reaction mechanism contains 140 reactions among 55 species. The cyclic hydrocarbon chemistry is mainly based on studies of polycyclic aromatic hydrocarbon formation in cosmic environments. The model explicitly includes organic chain, cyclic molecules, radicals, and ions up to a size of 12 carbon atoms. The calculated density profiles show that the aromatic formation yields are quite significant, suggesting that aromatic compounds play a role in the underlying mechanisms of particle formation in hydrocarbon plasmas.

  • A two-step reaction process is reported for the synthesis of /sup 11/C, /sup 13/C, or /sup 14/C-labelled propargylamines in moderate yields. The propargylamines were prepared by a modified Mannich scheme without the use of acetylene. The reaction scheme involved the use of 2-methyl-3-butyn-2-ol followed by KOH-catalyzed elimination of acetone from the acetylenic carbinols. (BLM)
  • We compare near-infrared observations of the recently discovered outer rings of Uranus with HST results. We find that the inner ring, R/2003 U 2, is red, whereas the outer ring, R/2003 U 1, is very blue. Blue is an unusual color for rings; Saturn's enigmatic E ring is the only other known example. By analogy to the E ring, R/2003 U 1 is probably produced via impacts into the embedded moon Mab, which apparently orbits at a location where non-gravitational perturbations favor the survival and spreading of sub-micron sized dust. R/2003 U 2 more closely resembles Saturn's G ring.
  • The product gas yields for a 30 mTorr C{sub 2}H{sub 2} 13.56 MHz glow discharge were measured using mass spectrometry. The volatile products are H{sub 2}, C{sub 4}H{sub 2}, and C{sub 6}H{sub 2}. A reaction mechanism has been proposed that accounts quantitatively for the yields of C{sub 4}H{sub 2} and C{sub 6}H{sub 2}, and film deposition rate, as a function of discharge power. The product gases C{sub 4}H{sub 2} and C{sub 6}H{sub 2} are depleted at high rates in the plasma by electron collisional dissociation, and by reaction with H atoms and C{sub 2}H radicals. Under high power conditions suitablemore » for diamondlike carbon deposition it is proposed that the film growth is dominated by the radicals C{sub 4}H{sub 3}, C{sub 6}H{sub 3}, and C{sub 2}H. These results are compared with the kinetics of methane rf glow discharges under similar conditions. {copyright} {ital 1997 American Institute of Physics.}« less
  • The initial stage of nanoparticle formation and growth in radiofrequency acetylene (C{sub 2}H{sub 2}) plasmas is investigated by means of a self-consistent one-dimensional fluid model. A detailed chemical kinetic scheme, containing electron impact, ion-neutral, and neutral-neutral reactions, has been developed in order to predict the underlying dust growth mechanisms and the most important dust precursors. The model considers 41 different species (neutrals, radicals, ions, and electrons) describing hydrocarbons (C{sub n}H{sub m}) containing up to 12 carbon atoms. Possible routes for particle growth are discussed. Both positive and negative ion reaction pathways are considered, as consecutive anion- and cation-molecule reactions seemmore » to lead to a fast build up of the carbon skeleton.« less
  • The formation of polycyclic aromatic hydrocarbons (PAH), fullerenes, soot, and other carbonaceous materials during the combustion or pyrolysis of low-molecular weight hydrocarbons requires, at a minimum, that small molecules and/or reactive intermediates somehow become joined to make larger ones. Most likely, more than one type of intermolecular C-C bond-forming reaction plays a role. The accretion of C{sub 2}-units has long been considered a probable pathway for the stepwise growth of PAH in flames, but evidence also points to the operation of bimolecular processes in which both partners can be relatively large. The experiments reported here address the former paradigm andmore » provide clear support for a specific C{sub 2}-accretion pathway in which the key C-C bond-forming step involves the simple trapping of aryl radicals by acetylene (C{sub 2}H{sub 2}), both of which are abundant species in flames.« less
