ABSTRACT:
Disclosed is a one-step method of producing an industrial asphalt from a bituminous material which comprises mixing together without air-blowing:
(a) a feed material comprising a bituminous material having a viscosity of at least 50 centistokes at 350 degrees Fahrenheit and wherein the feed petroleum residuum forms a single phase when mixed with 5 percent ferric chloride; and
(b) from about 0.1 to 20.0 percent by weight of ferric chloride, said mixing being done at a temperature in the range of 351 to 600 degrees Fahrenheit, whereby the softening point of the feed is substantially increased and the penetration is significantly decreased.
