    摘要: This invention provides a process for producing a crude oil composition from oil sand using a solvent comprised of a hydrocarbon mixture to extract or remove only a portion of the bitumen on the oil sand. The solvent type and the manner by which the extraction process is carried out has substantial impact on the quality of the extracted oil component. The solvent is designed so that it has the desired Hansen solubility parameters that enable the partial extraction of the desired oil composition. The solvent is further designed so that it can be comprised of multiple hydrocarbons having the appropriate boiling point ranges that enable the solvent to be easily recovered and recycle, without the need to externally provide for solvent make-up.

    摘要: A method for production of pivalic acid comprising the steps of: (a) reacting isobutylene, carbon monoxide, and a first catalyst to produce a reaction mixture; (b) contacting the reaction mixture with water, thereby producing a crude acid product having pivalic acid and oligomeric neo-carboxylic acid; (c) then separating the pivalic acid and the oligomeric neo-carboxylic acid from the crude acid product; (d) then reacting the oligomeric neo-carboxylic acid with a source of carbon monoxide at a temperature of less than 200° C. in the presence of a second catalyst to produce a C5 carbocation product, wherein the first and second catalyst are either the same or different; and (e) reacting the C5 carbocation product with water; thereby producing pivalic acid having an overall yield of at least 80 wt. %.
