Abstract: A lubricating oil composition comprising a hydrocarbyl oil of lubricating viscosity, a metal-containing additive characterized by promoting the formation of hard deposits in an internal combustion engine, and a hydrocarbon-substituted succinimide represented by the formula: ##STR1## in which R is an aliphatic hydrocarbon radical having from about 1 to 50 carbon atoms and R' is a hydrocarbon radical having from 3 to 20 carbon atoms, and a method for lubricating an internal combustion engine.

Abstract: A nitrogen-boron-containing lubricant additive characterized by containing from 0.5 to 2.5 weight percent nitrogen and from 0.050 to 2.0 weight percent boron and a mineral lubricating oil composition containing same.

Abstract: Method for preparing a lactone reaction product comprising reacting an alkenylsuccinic acid under substantially anhydrous conditions in the presence of a protonating agent and at an elevated temperature ranging up to about 100.degree. C., and a motor fuel composition containing said lactone reaction product.

Abstract: Process for the production of an aliphatic alcohol comprising reacting an olefin having from 2 to 4 carbon atoms with sulfuric acid to form an ester reaction product, diluting said product with water and steam stripping to remove a lower aliphatic alcohol overhead leaving a dilute sulfuric acid solution, concentrating said dilute sulfuric acid solution in a first stage indirect evaporator, recycling the steam generated in this first stage evaporator to the steam stripping step, further concentrating the sulfuric acid solution in a second stage direct heat evaporator to form a concentrated sulfuric acid solution and recycling said concentrated sulfuric acid solution for reaction with fresh olefin feed.
