Highly flammable - note wide explosion limits. Further analysis of infrared spectroscopic data presented in July 2008[33] provided stronger evidence for the presence of liquid ethane in Ontario Lacus. At this low temperature, gaseous methane can be separated from the liquefied ethane and heavier hydrocarbons by distillation. Ethene-104 ° C. Trans-2-Butene. . Chem. Home | MSDS/SDS Database Search | It is primarily used to make films in packaging, carrier bags and trash liners. Many processes for producing this reaction have been patented, but poor selectivity for vinyl chloride and corrosive reaction conditions (specifically, a reaction mixture containing hydrochloric acid at temperatures greater than 500 °C) have discouraged the commercialization of most of them. Cooling this ethane below ca. This double bond causes the reactivity of ethene. [19][20], As far back as 1890–1891, chemists suggested that ethane molecules preferred the staggered conformation with the two ends of the molecule askew from each other. T boil: Normal Boiling Point Temperature (K). In this form, the positions of the hydrogen atoms are not fixed; the molecules may rotate freely around the long axis. Ethane (/ˈɛθeɪn/ or /ˈiːθeɪn/) is an organic chemical compound with chemical formula C2H6. There is a double bond between the two carbon atoms: a sigma bond and a pi … Am. Articles of ethene are included as well. The boiling points of the compounds increase as the number of carbon atoms in the compound increases. This process converts large hydrocarbons into smaller ones and introduces unsaturation. Thus, ethylene (C2H4) was the "daughter of ethyl" (C2H5). The complete combustion of ethane releases 1559.7 kJ/mol, or 51.9 kJ/g, of heat, and produces carbon dioxide and water according to the chemical equation. [13], Ethylene has long represented the major nonfermentative precursor to ethanol. Download as PDF file What is Ethene? Guidechem provides Methanaminium,1-carboxy-N,N,N-trimethyl-, chloride (1:1) chemical database query, including CAS registy number 590-46-5, Methanaminium,1-carboxy-N,N,N-trimethyl-, chloride (1:1) MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. National Institute of Standards and binary mixtures and chemical reactions, SRSD 2 – Web Thermo Tables (WTT), "lite" edition, SRSD 3 – Web Thermo Tables (WTT), professional edition, SRD 156 – Clathrate Hydrate Physical Property Database, https://doi.org/10.1007/978-94-009-3173-2, Based on data from 209. Vapor Pressures and Freezing Points of 30 Organics, Copyright for NIST Standard Reference Data is governed by McDonald, R.A.; Shrader, S.A.; Stull, D.R., Boiling point = −88.5 °C; The most common use of ethane is to produce ethene via steam cracking process. errors or omissions in the Database. Ethene, propene and the various butenes are gases at room temperature. ; Budarina, V.A., The bond angle between bonds of ethene is about 121.3 o. The curve between the critical point and the triple point shows the ethylene boiling point with changes in pressure. [12] Ethane is only very sparingly soluble in water. Oxidative chlorination of ethane has long appeared to be a potentially more economical route to vinyl chloride than ethene chlorination. In the chemical industry, more selective chemical reactions are used for the production of any particular two-carbon haloalkane. In addition, ethane is a refrigerant used in cryogenic refrigeration systems. [22] It can be produced via dehydration of ethanol with sulfuric acid or in the gas phase with aluminium oxide. [all data], Lebedev, Rabinovich, et al., 1967 that ethane produced in this fashion on Titan rained back onto the moon's surface, and over time had accumulated into hydrocarbon seas or oceans covering much of the moon's surface. It is not a carcinogen. [35], This article is about the chemical compound. A primary method is steam cracking (SC) where hydrocarbons and steam are heated to 750–950 °C. The H-C-H angle is 117.4°, close to the 120° for ideal sp² hybridized carbon. Lebedev, B.V.; Rabinovich, I.B. This error was corrected in 1864 by Carl Schorlemmer, who showed that the product of all these reactions was in fact ethane. Chem., 1946, 18, 234. T boil: Boiling point: T fus: Fusion (melting) point: T triple: Triple point temperature: Δ fus H: Enthalpy of fusion: Δ fus S: Entropy of fusion: Δ vap H: Enthalpy of vaporization: Δ vap H°: Enthalpy of vaporization at standard conditions Since the carbon atoms are composed of un-hybridized p orbitals, these orbitals can form a pi bond between the two carbon atoms. Physical Properties of Chemical Compounds, Advances in Chemistry Series No. Ref. in these sites and their terms of usage. Lebedev, B.V.; Rabinovich, I.B. Note: Cheméo is only indexing the data, follow the source links to retrieve the latest data.     T = temperature (K). Hence, names like ethylene oxide and ethylene dibromide are permitted, but the use of the name ethylene for the two-carbon alkene is not.
