In this work, benzotriazole derivatives were produced from the reaction of benzotriazole with formaldehyde and primary aliphatic amine, and performance evaluation and formula structure illustrated. The reaction was carried out at the temperature between 80～100 ℃ and in the presence of water solution, which had the feature of mild reaction condition, simple method, and high yielding rate. The molecular structures of the produce was identified by the elemental analysis and some spectra analysis(such as IR,HHMR,MS). Four ball machine and copper strip corrosive test etc. were performed to study the anti-wear and anti-corrosion and solubility in lubricating oil base and heat stability properties of this additive in base oil. The results show that the additive can improve solubility in lubricating oil base,and possessed good frictional characteristics, heat stability, the anti-wear and anti- corrosion performance. Particularly using a mixture of stearamine and catylamine to replace stearamine as raw material that lowered the production cost, and various index signs attain a request of oil additive. So the oiliness agent is a kind of multipurpose and good performance lube oil additive.
