A sample oil and aniline were mixed in equal volumes and heated in a beaker on a water bath, forming a homogeneous mixture. When cooled, the mixture became cloudy, indicating the formation of a product. The document also lists various petroleum products with their flash points and values for different apparatus used to measure viscosity, including time ranges, constants, and viscosity coefficients.
