Abstract:

The granular methyl-benzotriazole and liquid fatty amine were used as raw materials for synthesis of methyl-benzotriazole amine salts. The sample was characterized by FT-IR, gas chromatography, elemental analysis and VPO molecular weight techniques. The basic properties of the samples were investigated in terms of solubility, copper corrosion and four ball machine tests. The results show that the synthesized methyl-benzotriazole amine salt has higher purity, better performance in low temperature oil solubility, corrosion inhibition and wear resistance than benzotriazole amine.

Key words: liquid fatty amine, corrosion inhibition, methyl-benzotriazole amine salt
