Title: Tri:aryl phosphate hydraulic fluids stabilised to hydrolysis - by addn. of carbodiimide(s)
Inventor: HUEBNER JUERGEN DR
IPC: C10M169/04
Filed: 1980-03-20
Abstract: A low-flammability liq. for use in hydraulic systems is based on one or more triaryl phosphate esters, and also contains (A) a carbodiimide (pref. 0.001-0.5%) as hydrolysis inhibitor, esp. N,N'-dicyclohexyl-carbodiimide, N,N'-diisopropylcarbodiimide, or N,N'-bis(4-nitrophenyl)carbodiimide; and (B) other additives, including antioxidants, foam inhibitors, corrosion inhibitors, other hydrolysis inhibitors, etc. The tested aliphatic and cycloaliphatic carbodiimides were more effective than the tested aromatic carbodiimides. The carbodiimides are effective by reacting with traces of acidic partial esters of phosphoric acid, yielding urea derivs. and higher mol.wt. neutral esters. Thus acid is removed from the liq., and its catalytic effect on hydrolysis is lost. Used esp. in hydraulic systems of turbines and of diecasting-, continuous casting-, and pressing-plant. For the first time, synthetic low-viscosity trialkyl phosphate esters (viscosity class 150 VG 22) can be made to satisfy the BBC specification on hydrolytic stability (neutralisation number in test after earth treatment is 0.20 mg KOH/g max.). The hydrolytic stability of high-viscosity phosphate esters also is clearly improved.
