Abstract

The invention discloses a surfactant containing adamantane, namely 1,3-di(4-(2-sodium ethoxysulfonate)-phenyl)adamantane which is called adamantane-1,3-diphenyl ether sodium sulfonate for short and has a structural formula shown in the specification of the invention. In the preparation method of adamantane-1,3-diphenyl ether sodium sulfonate, adamantane is used as starting raw material; and the method comprises the following four steps of reactions: 1) firstly brominating adamantane to prepare 1,3-dibromoadamantane; 2) alkylating 1,3-dibromoadamantane to obtain 1,3-di(4-hydroxyphenyl)adamantane; 3) alkalifying 1,3-di(4-hydroxyphenyl)adamantane to obtain 1,3-di(4-hydroxyphenyl)adamantane sodium salt; and 4) finally performing condensation reaction between 1,3-di(4-hydroxyphenyl)adamantane sodium salt and halogenated sulfone alkylating reagent to synthesize adamantane-1,3-diphenyl ether sodium sulfonate. The method is simple to operate and has the advantages of higher product yield and the like, and the prepared product has high purity; and adamantane-1,3-diphenyl ether sodium sulfonate has potential application prospect in the fields of household chemicals, medicines, materials, chemical engineering and the like.

Description

technical field [0001] The invention relates to a surfactant containing adamantane and a preparation method thereof. Background technique [0002] Surfactant is an important branch of the fine chemical industry and an important part of the national economy. It is known as "industrial monosodium glutamate" and has a wide range of uses due to its good surface properties and application properties. The difference in its molecular structure will lead to obvious differences in the performance of surfactants. Studies have shown that the factors affecting surface activity are mainly the structure of hydrophilic groups and hydrophobic groups and their connection methods. When two hydrophilic groups are connected to a hydrophobic chain in the surfactant molecule to form an amphiphilic compound, the structure is similar to a simple weapon of the South American natives, Bola (made by connecting a small ball at both ends of a thin rope). into), which is a novel Bola-type surfactant [F...
