At 100 oF (38 oC) vapor pressure of 13.8 psia can be found in the boundary between gasolines (sg~0.71-0.77, per wikipedia) and natural gasolines (typical sg=0.67, per wikipedia). 21/02/2018 . Benzene is less dense than water and is slightly soluble in water. It consists of hydrocarbons with carbon numbers predominantly in the range be-tween C6 and C13, has a boiling point in a range approximately between 65C and "Light" naphtha has a range of more evaporative molecules like hexanes or pentanes. Heating causes rise in pressure with risk of bursting. The light naphtha fraction produced in naphtha splitters is sent to an isomerisation unit where benzene is saturated to form cyclohexane. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. endstream endobj 425 0 obj <>/Metadata 14 0 R/Pages 422 0 R/StructTreeRoot 20 0 R/Type/Catalog>> endobj 426 0 obj <>/MediaBox[0 0 612 792]/Parent 422 0 R/Resources<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 427 0 obj <>stream The U.S. EPA's publication "AP 42, Compilation of Air Pollutant Emission Factors", Chapter 7, Table 7.1-2 gives the following True Vapor Pressures for Kerosene (which is essentially #1 Diesel: 40 deg F = 0.0041 psia 60 deg F = 0.0085 psia 80 deg F = 0.015 psia 100 deg F = 0.029 psia Three common factors that influence vapor press are surface area .

CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Naphtha refers to the light fraction produced by distillation that is roughly in the gasoline boiling range of ~30 C to ~200 C. Vapours may form explosive mixture with air. Vapours are heavier than air and may spread along . Naphtha is a generic term and could be a range of different chemicals inside. Light naphtha has a boiling range between 30 C and 90 C and 5-6 carbon atoms. vapour pressure, pressure exerted by a vapour when the vapour is in equilibrium with the liquid or solid form, or both, of the same substancei.e., when conditions are such that the substance can exist in both or in all three phases.
