Abstract
Abstract As novel compounds, monoalkanolamide borates having from 1 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
A composition comprising a liquid carrier selected from the group consisting of oil-in-water emulsions and water-in-oil emulsions, and a rust-inhibiting-effective amount of an alkanolamide borate which is the reaction product of orthoboric acid and a primary alkanolamine selected from the group consisting of monomethanolamine, monoethanolamine, 1-isopropanolamine, mono-n-propanolamine and 2-amino-2-methyl-propanolamine in a ratio of 1 gram mole of boric acid to 1 to 2 gram moles of alkanolamide, 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.
Claim 2
Dependent Claim
101 words
A composition comprising a liquid carrier selected from the group consisting of oil-in-water emulsions and water-in-oil emulsions, and a rust-inhibiting-effective amount of an alkanolamide borate which is the reaction product of orthoboric acid and a primary alkanolamine selected from the group consisting of monomethanolamine, monoethanolamine, 1-isopropanolamine, mono-n-propanolamine and 2-amino-2-methyl-propanolamine in a ratio of 1 gram mole of boric acid to 1 to 2 gram moles of alkanolamide, 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.
Claim 3
Dependent Claim
28 words
A composition as set forth in claim 1, wherein the primary alkanolamide borate is present in an amount from about 0.05% to 5% by weight of the composition.
Claim 4
Dependent Claim
16 words
A composition as set forth in claim 1, wherein the carrier is a cutting oil/water emulsion.
