nonane

nonane Nonane is an organic hydrocarbon belonging to the alkane series with nine carbon atoms in a straight or branched chain. It appears as a colorless, flammable liquid under standard conditions and is notable in industrial chemistry, petrochemical refining, and organic synthesis. Its occurrence and handling intersect with institutions, standards bodies, industrial manufacturers, regulatory agencies, and notable historical developments in chemical engineering.

Structure and Isomers

The compound features a nine-carbon saturated alkane backbone whose structural description is central to discussions in organic chemistry, crystallography, and molecular modelling as addressed by institutions such as IUPAC, Royal Society of Chemistry, American Chemical Society, Max Planck Society, and Massachusetts Institute of Technology. Structural representations and conformational analyses commonly reference researchers and works from Linus Pauling, F. A. Cotton, Roald Hoffmann, Dorothy Crowfoot Hodgkin, and computational groups at Bell Labs and IBM Research. Chain isomerism yields a set of constitutional isomers discussed in textbooks from Oxford University Press, Cambridge University Press, Wiley-VCH, and courses at Harvard University, Stanford University, and University of California, Berkeley. The isomer count and named branched forms are tabulated in databases maintained by PubChem, NIST, ChemSpider, European Chemicals Agency, and Chemical Abstracts Service.

Physical and Chemical Properties

Physical properties such as vapor pressure, flash point, and heat of combustion are reported by agencies including American Petroleum Institute, U.S. Environmental Protection Agency, Occupational Safety and Health Administration, and Health Canada. Typical thermodynamic and spectral data derive from experimental programs at National Institute of Standards and Technology, Brookhaven National Laboratory, and university laboratories at University of Cambridge and ETH Zurich. Chemical reactivity—combustion, radical halogenation, catalytic dehydrogenation, and isomerization—is discussed in literature from Dow Chemical Company, ExxonMobil, Shell, BASF, and academic groups publishing in Journal of the American Chemical Society, Angewandte Chemie, Journal of Organic Chemistry, and Chemical Reviews. Analytical characterization employs techniques standardized by ASTM International, ISO, British Standards Institution, and instrumentation vendors such as Agilent Technologies, Thermo Fisher Scientific, and Bruker.

Synthesis and Production

Production pathways for nine-carbon alkanes are embedded within petroleum refining, Fischer–Tropsch synthesis, and catalytic upgrading processes studied at Royal Dutch Shell, Chevron, Sasol, Aramco, and research centers like Lawrence Berkeley National Laboratory and Argonne National Laboratory. Historical developments in hydrocarbon processing reference figures and milestones connected to Hugo Rehn, Franz Fischer, Hans Tropsch, Carl Bosch, and Fritz Haber. Modern synthesis routes include cracking, hydrocracking, alkylation, and selective hydrogenation in plants designed by engineering firms such as Fluor Corporation, Bechtel, and Jacobs Engineering Group. Supply chain aspects link to commodity trading floors and exchanges like New York Mercantile Exchange, London Metal Exchange, and regulatory oversight by European Commission and national ministries of energy.

Applications and Uses

Nine-carbon alkanes serve as components in fuels, solvents, specialty hydrocarbons, and formulation streams used by automotive manufacturers Toyota, General Motors, Volkswagen Group, Ford Motor Company, and aerospace contractors such as Boeing and Airbus. They appear in gasoline blending research published by Society of Automotive Engineers and in lubricant additive studies by Mobil 1 researchers. Industrial chemistry applications include feedstocks for producing surfactants and intermediates in fine chemical syntheses at firms such as Evonik Industries, Clariant, and DuPont. Performance testing and regulatory compliance tie to standards from ASTM International, EPA, European Chemicals Agency, and consumer safety oversight agencies like Food and Drug Administration when hydrocarbons intersect with product formulations.

Safety and Environmental Impact

Safety data, exposure limits, and incident histories are catalogued by Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, European Chemicals Agency, and World Health Organization. Environmental fate, photochemical smog formation potential, and persistence are topics of study in programs run by U.S. Environmental Protection Agency, United Nations Environment Programme, Intergovernmental Panel on Climate Change, and academic groups at Imperial College London and California Institute of Technology. Remediation practices and risk assessments are undertaken by consulting firms such as AECOM, Tetra Tech, and CH2M Hill and guided by legislation like acts and directives enacted by United States Congress and the European Parliament. Storage, transport, and emergency response procedures align with recommendations from International Maritime Organization, International Civil Aviation Organization, and national fire protection codes influenced by National Fire Protection Association.
