Abstract: Disclosed is a continuous process for the sulfonation of an alkylaromatic reactant involving heating liquid sulfur trioxide in a vaporizer and mixing this sulfur trioxide gas stream with a hexane-alkylaromatic stream containing about 1 to about 3 wt. % quantity of a promoter, which can be either sulfuric acid or an alkyl benzene sulfonic acid, in a sulfonator - static inline mixer, mixing water with the sulfonated product as it passes to the water reactor - static inline mixer, passing the aqueous sulfonated product through degassing column-heat exchanger apparatus and separating the sulfonated product from the aqueous sulfuric acid. The reaction is conducted under controlled temperature and pressure conditions.

Abstract: Instead of total base number of about 30 for an alkaline earth metal sulfonate prepared by reacting up to 200 molar excess of alkaline earth metal compound at a temperature above 104.degree. C. with an alkylbenzene sulfonic acid in the presence of from 0.5 to 10 weight parts of water per 1.0 weight part of alkaline earth metal compound under a pressure of from 2 to 10 atmospheres an oil-soluble magnesium-alkylbenzene sulfonate of total base number of 400 and higher is obtained by reacting at least on 8.5 to 1.0 molar ratios of magnesium oxide to ammonium alkylbenzene sulfonate at a temperature of from 100.degree. C. to 130.degree. C. under autogeneous pressure in the presence of at least 1.1 weight parts of water and 0.3 to 0.5 of methanol per weight part of magnesium oxide. After decompressing and removing water and methanol, the product high base number magnesium alkylbenzene sulfonate is obtained.

Abstract: Cyclic phosphite structure-containing polyalkyl hindered phenol tetramers are disclosed as novel compounds useful to impart to lubricant oils oxidation and corrosion inhibition. A novel preparative method for the cyclic phosphite-containing polyalkyl hindered phenol tetramers is also disclosed wherein at least a molar excess of a tri(C.sub.1 to C.sub.4 alkyl) phosphite is reacted in the presence of iodine as catalyst with a polyalkyl hindered phenol tetramer of the formula: ##STR1## wherein the sum of the carbon atoms in all the R.sub.1, R.sub.2, and R.sub.3 groups is at least 42 and wherein R.sub.1 and R.sub.2 can be C.sub.1 to C.sub.12 alkylhydrocarbon groups and the R.sub.3 groups can each have as many as 200 carbon atoms. The trialkyl phosphite reacts with a pair of adjacent hydroxyl groups to split out 2 molecules of alkanol and form the cyclic phosphite structure: ##STR2## within said tetramer structure. Said R.sub.4 group is the C.sub.1 to C.sub.4 alkyl from the trialkyl phosphite.
