Embodiment Construction

[0023] 1. Synthesis steps of (2,2'-diethylferrocenyl)undecyltrimethylammonium bromide:

[0024] 1. Add 69.5 g (0.516 mol) of finely ground aluminum trichloride and 200 mL of dichloroethane into a 1000 mL three-necked flask, and add 38.8 g (0.495 mol) of acetyl chloride and 350 mL of dichloroethane dropwise under stirring at room temperature The mixed solution of alkanes was stirred until the aluminum trichloride was basically dissolved, and the mixed solution of acetyl chloride-aluminum trichloride was obtained and set aside.

[0025] Add 40 g (0.215 mol) of ferrocene and dichloroethane into another 1000 mL three-necked flask, adjust the temperature of the mixture of ferrocene and dichloroethane in the bottle to 5-10°C, and then add acetyl chloride dropwise -Aluminum trichloride mixed solution, stirred at room temperature for 1 h, and finally stirred at 40°C until no hydrogen chloride was released. Add water to the reaction solution, separate the organic phase, extract the wa...

Abstract

The invention provides a ferrocenyl-based redox-reversible surfactant and a preparation method thereof, and relates to the field of redox switch type surfactants. The ferrocenyl-based redox-reversible surfactant is prepared from a precursor compound ferrocene, acetyl chloride, zinc amalgam, bromoundecanoic acid, thionyl chloride and trimethylamine as raw materials. The synthesized surfactant molecules are easy to prepare, the yield of the intermediate diacetylferrocene is effectively improved, a new feeding sequence is provided, and the problem of reduction of ferrocene due to oxidation reaction is effectively solved. The surfactant can be used as an electrode surface modification material for glucose detection.

Description

technical field [0001] The invention relates to a preparation method of a ferrocene-based redox switch type surfactant. Background technique [0002] Surfactants have many important functions in practical applications, but after the surfactant completes its surface active function, it is difficult to detach from the system or lose its surface activity. Switching surfactants are getting better and better at solving this problem. The so-called switch-type surfactant is to trigger the change of the molecular structure of the surfactant in the aqueous solution through certain chemical and electrochemical methods, so that the corresponding surface tension changes greatly. Correspondingly, some macroscopic surfaces of the system The nature changes. Electrochemically controlled switch-type surfactants are mainly controlled to have or not have surface active functions by adjusting the oxidation-reduction state by electrochemical methods. In 1985, Tetsuo Saji and others synthesize...
