Bitumen hydrolysis
WebBitumen. Bitumen is a black, semi-solid or liquid substance with high viscosity produced by the non-destructive distillation of crude oil during petroleum refining. The core industry using bitumen is road construction (asphalt) and another significant field is the building industry (roofing membranes, water-proofing felts). MOL’s bitumens ... Webshows its hydrolysis reaction. Typically, the silane is functional at both ends and R is an active chemical group such as amino (NH2), mercapto (SH) or isocyanato (NCO) . This functionality can react with functional groups in an industrial resin or bio molecule such as peptides, oligonucleotides or DNA fragments. The other end consists of a halo

As well as this, its low boiling point (40°C) gives it fast-drying properties which are great for adhesive aerosols. WebThe rheological properties of bitumen can be determined, for example, by oscillatory tests at variable temperature (in the range of T = 0 °C to +70 °C). Synthetic polymers are often used to optimize the viscoelastic behavior of road pavement. Usually, the components of pure bitumen have less influence on its rheological behavior than the added synthetic polymers.
WebIn contrast, the hydrolysis data obtained from the two bitumen blends gave significant dependence of hydrolysis on salt concentration (Fig. 2). Both crude oils gave inhibition of hydrolysis relative to the model oil at concentrations < 450 ppmw, then acceleration of hydrolysis to a maximum of 10.5-11% chloride release.
