Unreferenced date December 2009 Orphan date October 2006 att June 2011 Hydrocarbon mixtures are a group of various Volatility chemistry volatile , highly flammable , mixtures used chiefly as nonpolar solvents . Composition Hydrocarbon mixtures are composed of petroleum ether s and other hydrocarbon s. Petroleum ether should not be confused with the class of organic compounds called ethers and equally, going under its alternative name of benzine , it should not be confused with benzene . Benzine is a mixture of alkanes , such as pentane , hexane , and heptane whereas benzene is a cyclic, aromatic hydrocarbon . A hydrocarbon is any chemical compound that consists only of the chemical element element s carbon C and hydrogen H . They all contain a carbon frame, and have hydrogen atoms attached to the frame. Often the term is used as a shortened form of the term aliphatic hydrocarbon . Most hydrocarbons are combustible . Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene . It has a specific gravity of between 0.6 and 0.8 depending on its composition. DEFAULTSORT Hydrocarbon Mixtures Category Alkanes Category Hydrocarbon solvents ... more details

The standard enthalpy of combustion is the enthalpy change when one mole unit mole of a reactant completely reacts with oxygen under Standard conditions for temperature and pressure standard thermodynamic conditions although experimental values are usually obtained under different conditions and subsequently adjusted . By definition, combustion reactions are always exothermic and so enthalpies of combustion are always negative, although the values for individual combustions may vary. The most common way of calculating the enthalpy change of combustion or formation is by using a Hess cycle or by using numerical based bond enthalpies. It is commonly denoted as math Delta H circ mathrm comb math or math Delta H circ mathrm c math . When the enthalpy required is not a combustion, it can be denoted as math Delta H circ mathrm total math . Enthalpies of combustion are typically measured using calorimeter bomb calorimetry , and have units of energy typically kJ strictly speaking, the enthalpy change per mole of substance combusted is the standard molar enthalpy of combustion which typically would have units of kJ mol sup &minus 1 sup . Comparisons Hydrocarbons The standard enthalpy change of hydrocarbons vary depending on their molecular size. For instance, the standard enthalpy change of Methane CH sub 4 sub is 890.3 kJ mol sup 1 sup , whereas the standard enthalpy change Hexane C sub 6 sub H sub 14 sub is 4163.0 kJ mol sup 1 sup . This is due to the presence of more bonds in Hexane compared to Methane. Methane has only 4 bonds between its single carbon and four Hydrogen atoms. Hexane on the other hand, has 5 carbon carbon bonds and 14 carbon hydrogen bonds. Therefore, there is more bond making and bond breaking during the combustion of a larger hydrocarbon compared to a smaller hydrocarbon, thus the enthalpy change is larger for each mole of the substance. Alcohols and alkanes For alcohols and alkanes containing the same number of carbon atoms, e.g. Methane CH sub 4 sub ... more details
A multiphasic liquid is a mixture consisting of more than two miscibility immiscible liquid Phase matter phases . Biphasic mixtures consisting of two immiscible phases are very common and usually consist of an organic compound organic solvent and an water molecule aqueous phase oil and water . Multiphasic liquids are rare and only triphasic three phases and tetraphasic four phases are known. Multiphasic liquids can be used for selective liquid liquid extraction s or for decorative purposes, e.g. in cosmetics . While it is possible to get multilayered phases by layering Nonpolarity nonpolar and aqueous phases of decreasing density densities on top of each other, these phases will not separate after mixing like true multiphasic liquids.
