Abstract

518,655. Bituminous materials. EBANO ASPHALT-WERKE AKT.-GES. Sept. 1, 1938, No. 25650. Convention date, Sept. 6, 1937. [Class 91] Bituminous materials having a high resistance to heat and cold and a low viscosity, suitable for use in binding, saturating and adhesive compositions, are obtained by airblowing asphalt free viscous mineral oil distillates, obtained from crude oils with an asphalt basis or a mixed basis, at 160‹ to 200‹C. for 30 to 200 hours. The blowing may be accelerated by the addition of catalysts consisting of metal oxides and their salts or soaps, e.g., naphthenates sulphonates, stearates, or resinates of copper, lead, manganese, cobalt, iron or chromium. The blown asphalt may be treated with an alkali or an alkaline earth or a mixture of these. In an example, 40 kg. of a mineral oil of sp. gr. 0.956, flashpoint 225‹ C. and Engler viscosity at 50‹C., 10.2, are blown at 170 to 180‹ with 74,000 litres of air for 197 hours. The resulting mineral distillate has a sp. gr. of 1.001 at 15‹C., a penetration of 150 at 15‹C., and of 214 at 25‹C., a dropping point (Ubbelohde) of 119‹C., a softening point of 94‹C. (ball and ring) and 50‹ (Kramer-Sarnow), a ductility of 0.5 cm., breaking point (Fraass) below -20‹C., a viscosity (Engler) at 150‹C. of 10.4.
