ABSTRACT:
Multifunctional additives having a variety of advantageous properties are described. They are formed by a process which comprises heating concurrently or in any sequence a) an oil-soluble ashless dispersant containing basic nitrogen with b) an alkoxylated alcohol of at least 8 carbon atoms c) a borating agent and optionally d) an inorganic oxyacid or anhydride of phosphorous. The reactants are in proportions on an active ingredient basis of about 0.03 to about 0.35 part by weight of b) per part by weight of a), and about 0.005 to about 0.06 part by weight of boron as c) per part by weight of a). The reaction temperature can range from about 50.degree. to about 150.degree. C. Water and/or solids present in the resultant mixture can be removed. Preferably, the optional phosphorous component is used in the formation of these additives. This phosphorous component can be an inorganic oxyacid or anhydride of phosphorous.
