Embodiment 1

[0047] Hydrogenated rosin-based quaternary ammonium salt gemini surfactant, the structural formula is as follows:

[0048]

[0049] In the formula, R is the tricyclic phenanthrene structure of dihydroabietic acid of hydrogenated rosin,

Embodiment 2

[0051] Hydrogenated rosin-based quaternary ammonium salt gemini surfactant, the structural formula is as follows:

[0052]

[0053] In the formula, R is the tricyclic phenanthrene structure of tetrahydroabietic acid of hydrogenated rosin,

Embodiment 3

[0055] Prepare the method for the hydrogenated rosin-based quaternary ammonium salt gemini surfactant as embodiment 1 or embodiment 2, comprise two steps:

[0056] (1) Esterification of hydrogenated rosin and epichlorohydrin to synthesize an intermediate; (2) Quaternization of the intermediate with tetramethylethylenediamine to obtain a hydrogenated rosin-based quaternary ammonium salt gemini surfactant.

[0057] (1) The esterification reaction comprises the following steps: the mass ratio of hydrogenated rosin to epichlorohydrin is 1:2, and the addition of tetrabutylammonium bromide is 2% of the mass of hydrogenated rosin to react, that is, 20 g of hydrogenated rosin, Add 0.4g of tetrabutylammonium bromide and 11mL of epichlorohydrin into a 250mL three-necked flask, and react at 500W microwave power at 70°C for 25s. Then the unreacted epichlorohydrin was distilled off, washed 5 times with hot distilled water, and dried to obtain an intermediate.

[0058] (2) The quaternizati...

Abstract

The invention discloses a hydrogenated rosin-based quaternary ammonium salt gemini surfactant. The surfactant has the following structural formula, wherein in the formula, R has a tricyclic phenanthrene structure of dihydroabietic acid or tetrahydroabietic acid of hydrogenated rosin. The invention also discloses a preparation method for the hydrogenated rosin-based quaternary ammonium salt gemini surfactant. The preparation method comprises the following steps of: performing esterification reaction on the hydrogenated rosin and epoxy chloropropane under microwave radiation to synthesize a 3-hydrogenated rosin acyloxy-2-hydroxypropyl chloride intermediate, performing quaternization reaction on the 3-hydrogenated rosin acyloxy-2-hydroxypropyl chloride intermediate and tetramethyl ethylenediamine, and thus obtaining the hydrogenated rosin-based quaternary ammonium salt gemini surfactant. Compared with the conventional heating synthetic method, the method using microwave radiation heating has the advantages that the reaction time can be greatly shortened and the preparation process is simple.

Description

technical field [0001] The invention relates to a quaternary ammonium salt gemini surfactant and a preparation method thereof, in particular to a hydrogenated rosin-based quaternary ammonium salt gemini surfactant and a preparation method thereof. Background technique [0002] Gemini surfactants are a new class of surfactants with a special molecular structure. The molecule is connected by a linking group through a chemical bond to connect the ionic head groups of two monomeric surfactants, resulting in many excellent properties. Such as high surface activity, ultra-low surface tension and strong synergistic effect, etc., which have been widely used. Gemini surfactants can be divided into cationic, anionic, nonionic and amphoteric gemini surfactants according to the different hydrophilic groups. Due to the relative ease of synthesis and purification, cationic gemini surfactants are more researched, especially It is a quaternary ammonium salt gemini surfactant. Many surfact...
