A new class of compositions, tetrahydropyrimidyl-substituted compounds, useful as ashless bases and rust inhibitors, is prepared by reacting a C.sub.3 -to C.sub.50 amine containing a 1,3-diaminopropane group with ethylenediamine tetraacetic acid or nitrilotriacetic acid at a temperature of 150.degree. to 250.degree. C. for 10 to 100 hours.
