R.; Leite, T. C. M., Mota, C. J. A. a Universidade Federal do Rio de Janeiro, Instituto de Química ABSTRACT The catalytic hydrolysis of chloromethane to methanol and dimethyl ether (DME) was studied over metal- exchanged Beta and Mordenite zeolites, acidic MCM-22 and SAPO-5. The use of a second catalytic bed with HZSM-5 zeolite increased the selectivity to DME, due to methanol dehydration on the acid sites. The effect was more significant on catalysts presenting medium and weak acid site distribution, showing that dehydration of methanol to DME is accomplished over sites of higher acid strength.

  • Methanol Consumption Drives the Bacterial Chloromethane Sink in a Forest Soil
    The ISME Journal (2018) 12:2681–2693 https://doi.org/10.1038/s41396-018-0228-4 ARTICLE Methanol consumption drives the bacterial chloromethane sink in a forest soil 1,2 2 1,4 3 1 Pauline Chaignaud ● Mareen Morawe ● Ludovic Besaury ● Eileen Kröber ● Stéphane Vuilleumier ● 1 3 Françoise Bringel ● Steffen Kolb Received: 16 February 2018 / Revised: 1 June 2018 / Accepted: 15 June 2018 / Published online: 10 July 2018 © The Author(s) 2018. This article is published with open access Abstract Halogenated volatile organic compounds (VOCs) emitted by terrestrial ecosystems, such as chloromethane (CH3Cl), have pronounced effects on troposphere and stratosphere chemistry and climate. The magnitude of the global CH3Cl sink is uncertain since it involves a largely uncharacterized microbial sink. CH3Cl represents a growth substrate for some specialized methylotrophs, while methanol (CH3OH), formed in much larger amounts in terrestrial environments, may be more widely used by such microorganisms. Direct measurements of CH3Cl degradation rates in two field campaigns and in microcosms allowed the identification of top soil horizons (i.e., organic plus mineral A horizon) as the major biotic sink in a fi 1234567890();,: 1234567890();,: deciduous forest. Metabolically active members of Alphaproteobacteria and Actinobacteria were identi ed by taxonomic and functional gene biomarkers following stable isotope labeling (SIP) of microcosms with CH3Cl and CH3OH, added alone 13 or together as the [ C]-isotopologue. Well-studied reference CH3Cl degraders, such as Methylobacterium extorquens CM4, were not involved in the sink activity of the studied soil. Nonetheless, only sequences of the cmuA chloromethane dehalogenase gene highly similar to those of known strains were detected, suggesting the relevance of horizontal gene transfer for CH3Cl degradation in forest soil.

  • 4. Production, Import/Export, Use, and Disposal
    CHLOROMETHANE 149 4. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 4.1 PRODUCTION Table 4-1 lists the facilities in each state that manufacture or process chloromethane, the intended use, and the range of maximum amounts of chloromethane that are stored on site. The data listed in Table 4-l are derived from the Toxics Release Inventory (TRI96 1998). Only certain types of facilities were required to report. Therefore, this is not an exhaustive list. Based on the most current TRI information, there are currently 96 facilities that produce or process chloromethane in the United States. Chloromethane (also commonly known as methyl chloride) is both an anthropogenic and naturally occurring chemical. Anthropogenic sources include industrial production, polyvinyl chloride burning, and wood burning; natural sources include the oceans, microbial fermentation, and biomass fires (e.g., forest fires, grass fires). Chloromethane is produced industrially by reaction of methanol and hydrogen chloride (HCl) or by chlorination of methane (Edwards et al. 1982a; Holbrook 1992; Key et al. 1980). While the reaction of methanol with HCl is the most common method, the choice of process depends, in part, on the HCl balance at the site (the methane route produces HCl, the methanol route uses it) (Edwards et al. 1982a; Holbrook 1992). Typically, manufacturing plants that produce chloromethane also produce higher chlorinated methanes (methylene chloride, chloroform, and carbon tetrachloride). The methanol-HCl process involves combining vapor-phase methanol and HCl at 180-200 °C, followed by passage over a catalyst where the reaction occurs (Holbrook 1992; Key et al. 1980). Catalysts include alumina gel, gamma alumina, and cuprous or zinc chloride on pumice or activated carbon.

Seifertb a Meteorological Institute, CEN, University of Hamburg, Hamburg, Germany b Institute for Geology and Marine Chemistry, University of Hamburg, Hamburg, Germany c Department of Geography, School of Global Studies, University of Sussex, Brighton, UK ARTICLE INFO ABSTRACT Keywords: Chloromethane (CH3Cl) and dichloromethane (CH2Cl2) are known to have both natural and anthropogenic Chloromethane sources to the atmosphere. From recent studies it is known that tropical and sub tropical plants are primary Dichloromethane sources of CH3Cl in the atmosphere. In order to quantify the biogenic emissions of CH3Cl and CH2Cl2 from Mangrove mangroves, field measurement were conducted in a tropical mangrove forest on the coast of Brazil. To the best of Emission our knowledge these field measurements were the first of its kind conducted in the tropical mangrove ecosystem METRAS of Braganca. A mesoscale atmospheric model, MEsoscale TRAnsport and fluid (Stream) model (METRAS), was used to simulate passive tracers concentrations and to study the dependency of concentrations on type of emission function and meteorology. Model simulated concentrations were normalized using the observed field data. With the help of the mesoscale model results and the observed data the mangrove emissions were estimated at the local scale. By using this bottom-up approach the global emissions of CH3Cl and CH2Cl2 from mangroves were quantified. The emission range obtained with different emission functions and different meteorology are −1 4–7Ggyr for CH3Cl and 1–2Ggyr2 for CH2Cl2.
