    Abstract: A method of affecting soot particulate size in an internal combustion engine exhaust by selectively providing a phosphorous based additive to the engine during combustion. Soot particulate size can be increased or decreased depending on the particular additive provided. Also disclosed in a conditioning effect experienced by using a phosphorous based additive for a period of time. A conditioned engine can also have its exhaust properties affected during the life of its conditioned state. Manipulating particle size during engine operation can employ an oligomeric phosphorous compound. Engine conditioning can employ a monomeric phosphorous containing compound, an oligomeric phosphorous containing compound, a polymeric phosphorous containing compound, or combinations thereof.

    Abstract: A method of preparing an oil-soluble composition is disclosed. The method comprises preparing a dihydrocarbyl monothiophosphoric acid characterized by the formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently hydrocarbyl groups of from 1 to about 30 carbon atoms and X is oxygen or sulfur, with the proviso that one X is sulfur comprising reacting(A) a phosphite ester of the structure ##STR2## with (B) a sulfur source, in the presence of(C) a catalytic amount of an amide of the structure R.sub.3 CONR.sub.4 R.sub.5 wherein R.sub.3, R.sub.4 and R.sub.5 are each independently hydrogen or a hydrocarbyl group containing from 1 to about 30 carbon atoms or an ethoxylated amide of the structure ##STR3## wherein the sum of x and y is from 1 to about 50; and isolating the reaction product obtained.
