摘要： In a method of removing acidic compounds, color, and polynuclear aromatic hydrocarbons, and for removing or converting hydrocarbons containing heteroatoms from petroleum distillates, phase transfer catalyst is employed to facilitate the transfer of inorganic or organic bases to the substrate of the distillate. An inorganic or organic base, a phase transfer catalyst selected from the group including quaternary ammonium salts, polyol ethers and crown ethers, and used oil distillate are mixed and heated. Thereafter, contaminants are removed from the used oil distillate through distillation. A solvent is then mixed with the resulting distillate to extract contaminants therefrom. The solvent is recovered and distilled to separate the contaminants therefrom, and is then reused. The petroleum distillate having the contaminants separated therefrom is also distilled to remove any remaining solvent therefrom, with the recovered solvent being reused.

摘要： Polynuclear aromatic hydrocarbons (PAHs) and other contaminants are removed from petroleum distillates by mixing a solvent with petroleum distillate to extract the contaminants therefrom. The solvent is recovered and distilled to separate the contaminants therefrom, and is then reused. The petroleum distillate having the contaminants separated therefrom is also distilled to remove any remaining solvent therefrom, with the recovered solvent being reused.

摘要： Micro-suspension polymerization is a technique that it is widely used on a commercial basis for the polymerization of vinyl chloride monomer into polyvinyl chloride. This invention reveals a greatly improved redox initiator system for use in such polymerizations. The redox initiator systems of this invention are comprised of (a) a free radical generator, such as a peroxide, and (b) a reducing agent selected from the group consisting of ascorbic acid, isoascorbic acid, and certain derivatives of ascorbic acid. The initiator systems of this invention do not require the utilization of water-soluble metal salts. However, water-soluble metal salts can be utilized in such initiator systems in catalytic amounts wherein the ratio of the water-soluble metal salt to the free radical generator is less than 0.09.
