decane decane decane is an alkane hydrocarbon with the chemical formula c10h22. although 75 structural isomers are possible for decane, the term usually refers to the normal-decane ("n-decane"), with the formula ch3(ch2)8ch3. all isomers, however, exhibit similar properties and little attention is paid to the composition. these isomers are flammable liquids. decane is present in small quantities (less than 1%) in gasoline (petrol) and kerosene. like other alkanes, it is a nonpolar solvent, and does not dissolve in water, and is readily combustible. although it is a component of fuels, it is of little importance as a chemical feedstock, unlike a handful of other alkanes. decane names preferred iupac name decane other names decyl hydride identifiers cas number 124-18-5 y 3d model (jsmol) interactive image beilstein reference 1696981 chebi chebi:41808 y chembl chembl134537 y chemspider 14840 y drugbank db02826 y echa infocard 100.004.262 ec number 204-686-4 mesh decane pubchem cid 15600 rtecs number hd6550000 unii nk85062oiy y un number 2247 comptox dashboard (epa) dtxsid6024913 inchi inchi=1s/c10h22/c1-3-5-7-9-10-8-6-4-2/h3-10h2,1-2h3 ykey: dioqzvsqgtusai-uhfffaoysa-n y smiles cccccccccc properties chemical formula c10h22 molar mass 142.286 g·mol−1 appearance colorless liquid odor gasoline-like (in high concentrations) density 0.730 g ml−1 melting point −30.5 to −29.2 °c; −22.8 to −20.6 °f; 242.7 to 243.9 k boiling point 173.8 to 174.4 °c; 344.7 to 345.8 °f; 446.9 to 447.5 k log p 5.802 vapor pressure 195 pa henry's lawconstant (kh) 2.1 nmol pa−1 kg−1 magnetic susceptibility (χ) -119.74·10−6 cm3/mol thermal conductivity 0.1381 w m−1 k−1 (300 k) refractive index (nd) 1.411–1.412 viscosity 0.850 mpa·s (25 °c) 0.920 mpa·s (20 °c) thermochemistry heat capacity (c) 315.46 j k−1 mol−1 std molarentropy (s⦵298) 425.89 j k−1 mol−1 std enthalpy offormation (δfh⦵298) −302.1–−299.9 kj mol−1 std enthalpy ofcombustion (δch⦵298) −6779.21–−6777.45 kj mol−1 hazards occupational safety and health (ohs/osh): main hazards flammable, moderately toxic ghs labelling: pictograms signal word danger hazard statements h226, h302, h304, h305 precautionary statements p301+p310, p331 nfpa 704 (fire diamond) 1 2 0 flash point 46.0 °c (114.8 °f; 319.1 k) autoignitiontemperature 210.0 °c (410.0 °f; 483.1 k) explosive limits 0.8–2.6% lethal dose or concentration (ld, lc): ld50 (median dose) >2 g kg−1 (dermal, rabbit)601 mg/kg−1 (oral, rat) safety data sheet (sds) hazard.com related compounds related alkanes nonaneundecane except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). y verify (what is yn ?) infobox references reactions decane undergoes combustion, just like other alkanes. in the presence of sufficient oxygen, it burns to form water and carbon dioxide. 2 c10h22 + 31 o2 → 20 co2 + 22 h2o with insufficient oxygen, carbon monoxide is also formed. other it has a surface tension of 0.0238 n·m−1.
