Abstract
Ashless corrosion inhibitor compositions including one or more reaction product formed from the reaction of a polyether compound of formula and a hydrocarbyl-substituted succinic anhydride of formula are provided herein, along with lubricant compositions containing same, and methods of using same for inhibiting corrosion of a metal.
Claims26
A reaction product comprising:
- a polyether component of formula
- where
- R is chosen from C1-C30 alkyl;
- X is chosen from OH, NHR1, wherein R1 is H or C1-C30 hydrocarbyl;
- y is an integer from 2 to 4;
- m and n are integers independently chosen from 0 to 40, provided that at least two of m or n are present, and wherein when both are present the distribution of m and n can be random or in any specific sequence;
- and
- p is 1 to 4;
- reacted with a substituted succinic anhydride component of formula
- where
- R2 is an optionally substituted C1-C100 alkyl or alkenyl;
- and
- wherein the reaction product is an ashless corrosion inhibitor.
