ABSTRACT:
A process for the production of a lubricating oil additive concentrate having a TBN greater than 300 which process comprises reacting
component (A) a defined derivative of phenol
component (B) an alkaline earth metal base added either in a single addition of in a plurality of additions at intermediate points during the reaction,
component (C) at least one compound which is (i) water, (ii) a C.sub.1 to C.sub.10 monohydric alcohol, (iii) a C.sub.1 to C.sub.20 ketone, (iv) a C.sub.1 to C.sub.10 carboxylic acid ester or (v) a C.sub.1 to C.sub.20 ether,
component (D) a lubricating oil,
component (E) carbon dioxide added subsequent to the, or each, addition of component (B),
component (F) a defined carboxylic acid or derivative
component (G) at least one compound which is (i) an inorganic halide or (ii) an ammonium alkanoate or a mono-, di-, tri, or tetra-alkyl ammonium formate or alkanoate provided that, when component (G) is (ii), component (F) is not an acid chloride,
the weight ratios of all components being such as to produce a concentrate having a TBN greater than 300.
