Synthesis and characterization of five phthalate phosphate, borate, phosphate-borate, polyglycol and alkanol esters as bases for hydraulic fluids

Phthalate esters of phosphate, borate, phosphate-borate, polyglycol and 2- [2-butoxy ethoxy methanol were prepared with the aim of producing hydraulic bas. fluids. Physico-chemical investigations of the prepared estrus were measured. Gas chromatography, infrared, nuclear magnetic resonance and mass spectrometry results confirm the structures of these compounds. The improvement in the specification of the ester bases may be achieved by the incorporation of the phthalic acid anhydride in the ester reaction. Thus providing hydraulic base fluids that are capable of being produced more economically and can monitor any pollution caused by fluid operations ensuring environment safeguard
