EC number: 272-895-8 | CAS number: 68919-37-9 A complex combination of hydrocarbons produced by the distillation of the products from a catalytic reforming process. It consists of hydrocarbons having carbon numbers predominantly in the range of C5 through C12 and boiling in the range of approximately 35°C to 230°C (95°F to 446°F).

Description of key information
Additional information
Key study data are available for each physicochemical endpoint for low boiling point (gasoline) naphthas. All substances in the category are liquid (CONCAWE 1992, 1997) at ambient temperature (20° C) and pressure (101.3 kPa). There is no guideline method available for this endpoint and data presented are based on visual observation, supported by data on melting point and viscosity. The melting point for chemicals in this category (represented by gasoline) is generally <-60°C (Eaton, 1990). Measured boiling points for members of this category range from -20 to 260°C (CONCAWE 2010) with the values for motor and aviation gasoline being 25°C to 200°C and 25°C to 170°C (CONCAWE 1992), respectively. The relative density range for the category is from 0.62 -0.88 (CONCAWE 2010) for the constituents of this category of chemicals while the vapour pressure range is 4 -240 kPa at 37.8°C (CONCAWE 2010).
Flash points for members of this category generally range from < 0°C to < 55°C (CONCAWE CJD 2009). Self-ignition temperatures for gasoline naphthas are in the range of 280°C to 470°C at 1013 hPa (Eaton 1990) and the flammability range is 1.4% (LFL) to 7.6% (UFL). Gasoline naphthas are not considered to be explosive and do not meet EU classification criteria for oxidising properties. The viscosity of substances in this category is less than 1 mm2/sec at 37.8°C (CONCAWE 1992).
Based on information available on the properties of the substances that comprise the gasoline naphthas category of chemicals, specific data are not presented for the following endpoints: partition co-efficient, water solubility, granulometry, surface tension, stability in organic solvents, and dissociation constant. Appropriate waiving statements are provided to indicate why data for these REACH endpoints are not applicable. The physico-chemical data presented are considered representative for the substances included in the category Low Boiling Point Naphthas (Gasolines).
