    Abstract: The first lubricating oil composition of the present invention is a composition comprising a polycarbonate represented by the following general formula, at least one compound as an essential component selected from the group consisting of epoxy compounds, phenol compounds, sulfur compounds and amine compounds, and a triester phosphite compound and a triester phosphate compound as an optical component. R1OCOOÄ(R2O)pCOOÜnR3 wherein R1 and R3 are each independently a specific hydrocarbon group or a specific hydrocarbon group containing an ether bond, R2 is a specific alkylene group, and p and n are specific integers. The lubricating oil compositions are excellent in lubricating properties, cleaning properties and electrical insulating properties, and their viscosity at low temperature can readily be lowered and, in addition thereto, generation of carbon dioxide gas can be inhibited.

    Abstract: PROBLEM TO BE SOLVED: To efficiently convert plastics into oil by melting the plastics followed by bringing them into contact with a solid acid catalyst to recover plastic stocks. SOLUTION: Plastics including polyolefins such as polyethylene and polypropylene and polystyrene are melted at >=300 deg.C and then brought into contact with a solid acid catalyst such as silica-alumina catalyst like acid clay or active clay at 400-500 deg.C for 0.1min to 5h, thus converting the plastics into oil.
