A process is disclosed for producing an isoparaffin white oil by contacting a refinery stream, in the presence of hydrogen, with a catalyst comprising an intermediate pore size silicoaluminophosphate molecular sieve and a hydrogenation component to form a dewaxed oil product. The dewaxed oil product is then contacted with a hydrogenation catalyst to produce a hydrogenated oil product which is then treated to remove aromatics to produce an isoparaffin white oil.

Lubricating oil compositions containing a combination of a polyamino alkenyl or alkyl succinimide modified to contain carbamate functionalities and a Group II metal overbased sulfurized alkylphenol unexpectedly possess little, if any, adverse compatability effects on deposits in diesel engines as compared to lubricating oil compositions containing a combination of an unmodified polyamino alkenyl or alkyl succinimides and a Group II metal overbased sulfurized alkylphenol.

Lubricating oil compositions containing a combination of a modified

Disclosed are overbased ortho-carboxy phenylphenones. The overbased ortho-carboxy phenylphenones provide detergency for the lubricating oil additionally providing an alkaline reserve.

Overbased ortho-carboxy phenylphenone lubricating oil additives

Disclosed are lubricating oil compositions containing the neutral and overbased ortho-carboxy phenylphenones. The neutral ortho-carboxy phenylphenones provide detergency for the lubricating oil; whereas, the overbased derivatives additionally provide an alkaline reserve.

Oil-insoluble metal thiolates prepared by reacting an acyloin, phosphorus pentasulfide and a heavy metal salt are rendered oil soluble when combined with alkenyl or alkyl mono- or bis-succinimides. The complexes are effective as anti-oxidants and anti-wear inhibitors in lubricating oils.

A process for polymerizing cycloalkenes into polyalkenamers is described wherein trisubstituted silyl groups are attached to the cycloalkenes. The silyl groups thus attached do not act as a poison to the polymerization process. Trimethylsilyl group can be substituted by other desired functional groups after the polymerization.
