EC number: 265-078-2
CAS number: 64741-77-1
A complex combination of hydrocarbons from distillation of the products from a hydrocracking process. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C10 through C18, and boiling in the range of approximately 160°C to 320°C (320°F to 608°F).
Key study data are available for each relevant physicochemical endpoint for vacuum gas oils, hydrocracked gas oils and distillate fuels. All substances in the category are liquids (CONCAWE, 2010a) 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 pour point and viscosity. The pour point for chemicals in this category ranges from -40 to 6°C (CONCAWE, 2010a). The boiling point for vacuum gas oils, hydrocracked gas oils and distillate fuels ranges from 141 to 462°C (CONCAWE, 2010a) and the density ranges from 0.8 to 0.91 g/cm3at 15°C (CONCAWE, 2010a). The vapour pressure is ~0.4 kPa at 40°C (CONCAWE, 1996).
Flash points for vacuum gas oils, hydrocracked gas oils and distillate fuels are generally >56°C and the self ignition temperature is typically =225°C (CONCAWE, 2010a). Vacuum gas oils, hydrocracked gas oils, and distillate fuels oilshaving flash points between = 55 °C and = 75 °C meet the CLP Regulation (EC No. 1272/2008) criteria as Category 3 Flammable Liquids (H226).Vacuum gas oils, hydrocracked gas oils, and distillate fuels oils do not met classification criteria for explosiveness, or oxidising properties under the EU CLP Regulation (EC)1272/2008.. The kinematic viscosity of substances in this category is =1.5 mm2/s at 40°C (CONCAWE, 2010a). Substances having a kinematic viscosity of =20.5 mm2/s at 40°C would meet classification criteria as aspiration hazard (H304) under CLP.
Based on information available on the properties of the substances that comprise the vacuum gas oils, hydrocracked gas oils and distillate fuels category of chemicals, specific data are not presented for the following endpoints: partition co-efficient, water solubility, granulometry, surface tension, flammability, explosiveness, oxidising properties, 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 vacuum gas oils, hydrocracked gas oils and distillate fuels.
