QUATERNARY AMMONIUM SALTS FOR CORROSION INHIBITION

摘要

The present disclosure provides a bis-quaternary ammonium salt of Formula I, wherein A is selected from O, NH, S, C(O), C(NH) or C(S); R₁ and R₂ are independently selected from C_1-3 alkyl or H; R₃ is C_1-16 alkyl, C_13-20 aralkyl or C_2-16 allyl; X^- is selected from chloro, bromo, iodo, hydroxide, nitrate or sulphate; and n and m are independently 1 to 6. Furthermore, a corrosion inhibition formulation comprising said bis-quaternary ammonium salt is revealed. Also, convenient processes for the preparation of the salt of Formula I and the formulation are provided.
