Embodiment 1

[0023] Weigh 927.2mg (1mmol) of tetradecyl alcohol dextrose gemini surfactant and 91.1mg (0.25mmol) of cetyltrimethylammonium bromide and dissolve them in 100mL distilled water respectively, then mix the above two prepared solutions evenly , and stirred at room temperature for 15 minutes to obtain a complex solution. The solution can be freeze-dried to obtain the complex white solid.

[0024] Surface activity test:

[0025] Under 20 ℃, the critical micelle concentration (cmc) of the target product measured by the platinum plate method is 0.0054mmol / L, which is 10 times higher than the activity of myristyl alcohol glucose gemini surfactant (cmc=0.053mmol / L) before compounding. Used in the separation and extraction of detergents and biofilm proteins.

Embodiment 2

[0027] Weigh 927.2 mg (1 mmol) of tetradecyl alcohol dextrose gemini surfactant and 91.1 mg (0.25 mmol) of cetyltrimethylammonium bromide and dissolve them in 100 mL of ethanol respectively, then mix the two solutions prepared above evenly , and stirred at room temperature for 15 minutes to obtain a complex solution. The solution can be freeze-dried to obtain the complex white solid.

[0028] The structural identification and surface activity test data of the myristyl alcohol glucose gemini surfactant prepared in this example are the same as those in Example 1.

Embodiment 3

[0030] Weigh 927.2 mg (1 mmol) of tetradecyl alcohol dextrose gemini surfactant and 91.1 mg (0.25 mmol) of cetyltrimethylammonium bromide and dissolve them in 100 mL of acetone respectively, and then mix the above-mentioned prepared two solutions evenly , and stirred at room temperature for 15 minutes to obtain a complex solution. The solution can be freeze-dried to obtain the complex white solid.

[0031] The structural identification and surface activity test data of the myristyl alcohol glucose gemini surfactant prepared in this example are the same as those in Example 1.

Abstract

The invention discloses a tetradecanol glucose dimeric surfactant compound, comprising a tetradecanol glucose dimeric surfactant and cetyl trimethyl ammonium bromide. The invention further discloses a preparation method of the tetradecanol glucose dimeric surfactant compound. The tetradecanol glucose dimeric surfactant compound disclosed by the invention not only has the high activity characteristic of a dimeric surfactant and can be applied to the separation extraction of a descaler and a biomembrane protein, but also has the characteristics of no toxicity or low toxicity and biodegradability and is a novel environment-friendly dimeric surfactant with a glycated dimer as a model; and the preparation method of the surfactant compound is simple and is easy for the implementation of industrialization.

Description

technical field [0001] The invention relates to the field of surfactant preparation, in particular to a myristyl alcohol glucose gemini surfactant compound and a preparation method thereof. Background technique [0002] The formation of an industry of surfactants and synthetic detergents needs to be traced back to the 1930s. Synthetic surfactants and detergents derived from petrochemical raw materials broke the dominance of soap in the world. The current research directions of surfactants mainly include Alkyl phosphorus carboxylate (AEC) industrial production, a new generation of Gemini surfactants, AB type block polymer surfactants, Bola type surfactants, Dendrimer type surfactants, low foaming or no foaming surfactants. With the continuous improvement of people's living standards and environmental protection awareness, traditional commercial surfactants can no longer meet people's requirements for surfactant safety, environmental protection and low cost, so they are gradua...
