Abstract: Benzotriazole phosphate derivative was designed, synthesized and characterized by means of FT-IR spectroscopy. The tribological properties and biodegradability of benzotriazole phosphate derivative as additive in liquid paraffin base oil were investigated and their reaction mechanisms were briefly discussed. Results show that the load carrying capacity, anti-wear and friction reducing properties of the base oil are improved significantly by adding said additive, furthermore, the biodegradability of liquid paraffin is improved as well, which infers that benzotriazole phosphate could be a potential environmental friendly lubricating additive．
