Abstract
Alkali metal borates are reacted with fatty acids or oils in the presence of a low HLB value surfactant to give a stable, mineral oil-soluble product. Mineral oil containing the borate can be used as a cutting fluid.
Claims11
A stable, mineral oil-soluble borate composition formed by reacting at a temperature in the range of about 50.degree. to 120.degree. C. an aqueous solution of an alkali metal borate with a fatty acid containing about 8-22 carbon atoms, fatty oil containing said fatty acid, or mixture thereof in the presence of about 1 to 10% of a surfactant selected from lanolin, ethylene glycol monostearate, and mixtures hereof, said composition containing about 5-30% of said alkali metal borate.
A method for the preparation of an alkali metal borate reaction product which is soluble in mineral oil which comprises reacting an aqueous solution of an alkali metal borate with a fatty acid containing about 8-22 carbon atoms, a fatty oil containing said fatty acid, or a mixture thereof, at an elevated temperature in the range of about 50.degree.-120.degree. C. in the presence of about 1 to 10% of a surfactant selected from lanolin, ethylene glycol monostearate, and mixtures thereof, said reaction product containing about 5 to 30% w/v of said alkali metal borate.
