As a new class of multifunctional additives for industrial fluids, the compounds having the following general formula IN WHICH EACH X and Y represents a heterocyclic nitrogen radical and may be the same or difficult for each occurrence of X and Y; Z is a basic nitrogen-containing radical; n is O or an integer of at least 1, preferably 1 to 10; and A, B, C, and D are linked groups derived from compounds which may provide desired functions, such as detergent, antioxidant, and antiwear properties, or indirectly useful functions, such as adsorbency. At least one of A, B, C, or D is amino or anilino or is derived from an alkenylsuccinimide or an alkyl lactam or tetrahydropyrrolidine, or alkyl-substituted Mannich base, having at least 8 carbon atoms in the alkenyl or alkyl radical, or combinations of any of these. When X is triazine in the (a)-type molecule, at least one of A, B, or C is amino or anilino. One method of preparing these novel additives is to react a halogenated heterocyclic nitrogen compound with an alkenylsuccinimide or a Mannich base or an alkyllactam or pyrrolidine of a polyamine. |
