    摘要: A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are polymers of specific quaternary ammonium monomers or co-polymers of these quaternary ammonium monomers wth other types of monomers wherein the greater portion of the co-polymer is comprised of the quaternary ammonium monomers. To resolve the bituminous petroleum emulsions, the process is carried out between 25.degree. and 160.degree. C. wherein the demulsifier of the invention is contacted with the bituminous emulsion.

    摘要: A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are ionenes prepared generally by reaction of ditertiary amines and dihalides. To resolve the bituminous petroleum emulsions, the process is carried out between 25.degree. and 160.degree. C. wherein the demulsifier of the invention is contacted with the bituminous emulsion.

    摘要: A corrosion-inhibited antifreeze composition is disclosed. Specifically, the antifreeze composition comprises a major portion of a liquid alcohol freezing point depressant and a minor portion of at least one hydroxyl-substituted aromatic carboxylic acid having the hydroxyl radical disposed proximate to the carboxylic radical. The above described acid is employed as a corrosion inhibitor. Other conventional corrosion inhibitors may be employed in conjunction with the acids.In another embodiment, the present invention relates to a process for inhibitig the corrosion of metals present in the cooling system of an internal combustion engine which comprises intimately contacting the metal surface to be inhibited against corrosion with the antifreeze composition described above. Most preferably, the target substrate is high lead solder.

    摘要: A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are polyamine salts prepared by contacting poly(ethyleneimines) with organic or inorganic acids. The polyamines have a molecular weight of at least 1,000. To resolve the bituminous petroleum emulsions, the process is carried out between 25.degree. and 160.degree. C. wherein the demulsifier of the invention is contacted with the bituminous emulsion.
