Abstract
A surfactant is synthesized from an amine or an alcohol and a hydrocarbyl-substituted succinic acylating agent by feeding the amine or alcohol into a stream comprising the hydrocarbyl substituted succinic acylating agent, to form a combined stream; passing the combined stream through an in-line mixer so as to effect premixing and initial reaction of the components; and thereafter passing the combined stream into a reactor, where the combined stream is further processed to form the surfactant.
Claims38
A method for synthesizing a surfactant from an amine or an alcohol and a hydrocarbyl-substituted succinic acylating agent, comprising:
- feeding the amine or alcohol into a stream comprising the hydrocarbyl substituted succinic acylating agent, to form a combined stream;
- passing said combined stream through an in-line mixer so as to effect premixing and initial reaction of the components;
- and thereafter
- passing the combined stream into at least one reactor, wherein said combined stream is further processed to form said surfactant.
A method for synthesizing a surfactant from water and a hydrocarbyl-substituted succinic anhydride, comprising:
- feeding the water into a stream comprising the hydrocarbyl substituted succinic anhydride, to form a combined stream;
- passing said combined stream through an in-line mixer so as to effect premixing and initial reaction of the components;
- and thereafter
- passing the combined stream into at least one reactor, wherein said combined stream is further processed to form said surfactant.
