Abstract
The present disclosure generally relates to a multifunctional additive obtained from the reaction of: (a) an intermediate obtained from the reaction of maleic anhydride and a polyoxyalkylene monoamine; and (b) an amine compound comprising a primary amine group and/or a secondary amine group and its use in a variety of applications, including, but not limited to: as a corrosion inhibitor or friction modifier in aqueous and non-aqueous systems; in fuel deposit control agents; as a dispersant in pigment, asphalt and cement compositions; and as a detergent.
Claims16
An additive compound obtained by the reaction of:
- (a) an intermediate formed from the reaction of maleic anhydride and a polyoxyalkylene monoamine;
- and (b) an amine compound comprising a primary amine group and/or a secondary amine group having the formula (I) or (II):
- wherein R5, R7 and R8, which can be the same or different, in each case are a hydrogen atom or a hydrocarbon group having 1 carbon atom to 60 carbon atoms, Y is —O— or an —NR9— group where R9 is a hydrogen atom or a hydrocarbon group having 1 carbon atom to 60 carbon atoms, R5 and R9 being able to form together with the nitrogen atom to which they are linked a heterocycle, each R6 is independently a hydrogen atom or a hydrocarbon group having 1 carbon atom to 4 carbon atoms, n, o and q are integers from 0 to 60 with the proviso that the sum of n+o+q is an integer from 1 to 60 and wherein when Y is —NR9—, p is an integer equal to or higher than 2 and m is zero or an integer between 1 and 10 and when Y is —O—, p is an integer equal to or higher than 1 and m is an integer between 1 to 10.
A method of forming an additive compound comprising reacting (a) an intermediate formed from the reaction of maleic anhydride and a polyoxyalkylene monoamine with (b) an amine compound comprising a primary amine group and/or a secondary amine group having the formula (I) or (II):
- wherein R5, R7 and R8, which can be the same or different, in each case are a hydrogen atom or a hydrocarbon group having 1 carbon atom to 60 carbon atoms, Y is —O— or an —NR9— group where R9 is a hydrogen atom or a hydrocarbon group having 1 carbon atom to 60 carbon atoms, R5 and R9 being able to form together with the nitrogen atom to which they are linked a heterocycle, each R6 is independently a hydrogen atom or a hydrocarbon group having 1 carbon atom to 4 carbon atoms, n, o and q are integers from 0 to 60 with the proviso that the sum of n+o+q is an integer from 1 to 60 and wherein when Y is —NR9—, p is an integer equal to or higher than 2 and m is zero or an integer between 1 and 10 and when Y is —O—, p is an integer equal to or higher than 1 and m is an integer between 1 to 10 at a temperature of from about 80° C. to about 110° C.
