Abstract
A polyetheramine produced from a cyclic amide initiator which is first alkoxylated and then reductively aminated to form the polyetheramine. The polyetheramine of the present disclosure may be used in a variety of applications, such as a raw material in the synthesis of a dispersant for use in an aqueous pigment dispersion or as a fuel additive in a hydrocarbon fuel composition.
Claims16
A polyetheramine comprising a compound having a formula (I)
- wherein R is a cyclic amide group having a formula (II)
- wherein n is an integer of from 3 to 15, R0 is a substituent that can replace hydrogen in any hydrocarbon portion of the cyclic amide group and is an alkyl group or an aryl group, p is an integer of from 0 to 2n and X* denotes the attachment site of the cyclic amide group to the rest of the cyclic amide initialized polyetheramine compound;
- R1 and R2 are each independently hydrogen, methyl or ethyl and each R1 and R2 is independently selected in each —O—CHR1-CHR2- unit;
- A is an N-alkyl amino having 1 to about 20 carbon atoms in the alkyl group;
- and
- m is an integer ranging from about 2 to about 200.
