PURPOSE:To obtain a novel superior corrosion inhibitor for metal by using a specified bisphenol type quat. ammonium compound as a principal component. CONSTITUTION:A novel bisphenol type quat. ammonium compound represented by the formula is synthesized. In the formula, X is a counter ion to quat. ammonium, Y is 1-6C alkylene, -O-, -S-, -SO- or -SO4-, each of R1-R4 is same or different to each other and H, 1-3C alkyl or hydroxyalkyl respectively, R5 is alkylene, hydroxyalkylene, hydroxyaralkylene, aminoalkylene, aminoaralkylene or alkylene or aralkylene having amido or ether bond, and R6 is halogen or alkyl bonded to each phenylene group by addition or substitution. The quat. ammonium compound is used as a principal component to obtain a corrosion inhibitor for metal. |
