Abstract

The invention belongs to the field of surfactants and particularly relates to a saturated anacardol ether sulfonate surfactant as well as a preparation method and application of the saturated anacardol ether sulfonate surfactant. According to the preparation method, saturated anacardol is taken as a starting material to be subjected to serial reactions to generate an anionic surfactant with a double-tail structure, namely saturated anacardol ether sulfonate; the surface (interface) performance of the anionic surfactant is good due to the unique double-tail structure, the anionic surfactant can form low (or ultralow) interfacial tension with simulated oil alkane or crude oil when being independently used or compounded with other auxiliary agents, has good application prospects in numerous fields including mineral floatation, industrial washing, tertiary oil recovery and the like and can be taken as an efficient oil displacement agent to be applied to the tertiary oil recovery. The saturated anacardol ether sulfonate surfactant has a following structure shown in the specification.

Description

technical field [0001] The invention belongs to the field of surfactants, and particularly relates to a saturated cardanol ether sulfonate surfactant and a preparation method and application thereof. Background technique [0002] Sulfonates are the most widely used anionic surfactants in heavy oil emulsification, foam flooding or binary (ternary) flooding systems; among them, alkyl benzene sulfonate surfactants are industrialized tertiary oil recovery surfactants. One of the main products, and one of the largest surfactants in tertiary oil recovery. There are two main sources of raw materials for lipophilic groups of surfactants: one is mineral (fossil) resources, mainly referring to petroleum resources; the other is renewable biomass resources, which refer to vegetable oils and animal oils. Currently, petroleum-based products account for 75% of the global surfactant market. With the gradual rise in oil prices and increasing environmental awareness, sustainable development...
