ADDITION AGENT TO LUBRICANT MATERIALS AND A METHOD OF ITS PREPARING Russian patent published in 1998 - IPC

FIELD: lubricant materials. SUBSTANCE: addition agent is a product of interaction of saturated carboxylic acid with ammonium group and halogen alcoholic solution. Composition of proposed addition agent and a method of its preparing ensures to decrease energy capacity of addition agent synthesis by 1.24-fold, decrease its time by 1.4-fold, increase the yield of ready product to 100%, improve antifriction and antiwearing properties of lubricant material by 1.07 and 1.06-1.19-fold, respectively, decrease corrosion activity of oil by 1.07-1.16-fold, provide the increased antioxidant stability by alkaline number and viscosity (by 1.02-1.18 and 1.03-fold, respectively). EFFECT: improved tribological properties of lubricant material. 2 cl, 1 dwg , 4 tbl
