As novel compounds, monoalkanolamide borates having from 2 to 3 carbon atoms in the alkanol moiety and in which the moiety is substituted or unsubstituted, a method for making and using the same, and the use thereof as rust-inhibitors and as synergistic lubricative-enhancive addenda. The new compounds also have bactericidal and fungicidal properties.

A composition comprising a liquid carrier constituting a hydraulic fluid base on mineral oils, water-in-oil emulsions, oil-in-water emulsions, and synthetic lubricating oil and a rust-inhibiting-effective amount of the reaction product of orthoboric acid and a primary alkanolamine selected from the group consisting of monoethanolamine, monomethanolamine, 1-isopropanolamine, mono-n-propanolamine and 2-amino-2-methylpropanolamine in a ratio of 1 gram mole of boric acid to 1 to 2 gram moles of alkanolamine, the reaction taking place in a closed reactor for about 4 to 5 hours at a temperature between about 130°C. to about 165°C. with the water formed being removed during the reaction.
