Abstract

The invention belongs to high efficient surface activating agent filed, in particular relating to alkylPolyoxy divinyl ether and the anion surface activating agent preparation method and use. After a series of reaction, the alkyl aromatic hydrocarbon forms a nonionic to anion surface activating agent substance with an aryl benzyl structure. The molecular structure of the surface activating agent substance decides that the invention has low acrimony and toxicity, good degradation performance, good water solubility and hardwater resistance, high efficiency forming capability and excellent anti-salt performance; the surface activating agent has high activity, the critical tension with various different crude oil can reach super low (10 to 3Mn / m), which has good application prospect in domestic chemical, sanitation, three-time oil extracting, spinning industry, leatherworking, pesticide emulsion and other fields. The chemical structure of the surface activating agent is as the drawing.

Description

technical field [0001] The invention belongs to the field of high-efficiency surfactants, and in particular relates to an alkylaryl benzyl polyoxyethylene ether anionic surfactant of a nonionic-anionic surfactant, a preparation method and an application thereof. Background technique [0002] Anionic nonionic surfactants, such as alkylphenol ether polyoxyethylene ether sulfate and acetate, have two types of hydrophilic groups, which overcome the adverse effects of low cloud points and greatly broaden the scope of nonionic surfactants. The application field of surfactant has been widely used in actual production. [0003] However, due to the presence of phenolic oxygen bonds in alkylphenol polyoxyethylene ethers, alkylphenols with strong biological toxicity will be produced during the degradation process, which limits their application in real life and industrial production. [0004] US4485873 discloses the application of polyoxyethylene alkylphenol ether acetate in enhanced ...
