Embodiment 1

[0033] The preparation of embodiment 1 formula Ⅰ-1 compound

[0034]

[0035] Dissolve 0.01mol maleated rosin acid chloride in 15ml benzene solution, then slowly add it dropwise to 0.04mol N,N-dimethylethanolamine benzene solution, the mixture of modified rosin acid chloride and N,N-dimethylethanolamine The molar ratio was 1:4. After 5 minutes, 4 mL of triethylamine was added dropwise as an acid-binding agent. After reacting for 3 hours at room temperature, viscous compound I-1 was obtained by rotary evaporation.

[0036] Using the same method as in Example 1, replacing N,N-dimethylethanolamine with other alcohols with 1-5 carbon atoms (not 1), the compound of formula I in which n is 1-5 (not 1) can be obtained is the compound of 1).

Embodiment 2

[0037] The preparation of embodiment 2 formula Ⅰ-2 compound

[0038]

[0039] Dissolve 0.01mol maleated rosin acid chloride in 15ml benzene solution and slowly add dropwise to 0.04mol N,N-diethylethanolamine benzene solution, the molar ratio is 1:4, after 5 minutes, add 4mL triethylamine dropwise Acid-binding agent, after reacting at room temperature for 3 hours, viscous compound I-2 was obtained by rotary evaporation.

[0040] Using the same method as in Example 2, replacing N,N-diethylethanolamine with other alcohols with 1-5 carbon atoms (not 1), the compound of formula I in which n is 1-5 (not 1) can be obtained is the compound of 1).

Embodiment 3

[0041] The preparation of embodiment 3 formula Ⅱ-1 compound

[0042]

[0043] Dissolve 0.05 mol of acrylic acid-modified rosin acid chloride in 75 ml of benzene solution and slowly add it dropwise to 0.15 mol N,N-dimethylethanolamine benzene solution, the molar ratio is 1:3, after 5 minutes, add 5 mL of triethylamine to bind Acid agent, reacted at room temperature for 3 hours, and then evaporated to obtain viscous compound Ⅱ-1.

[0044] Using the same method as in Example 3, replacing N,N-dimethylethanolamine with other alcohols with a carbon number of 1-5 (not 1), the compound of formula II in which n is 1-5 (not 1) can be obtained is the compound of 1).

Abstract

The invention relates to the technical field of surfactants, in particular to a rosin-based tertiary ammonium surfactant and a preparation method and application thereof. The rosin-based tertiary ammonium surfactant has the structures shown in formula I and formula II, wherein n is 1-5, and R is -CH3 or -C2H5. The surfactant prepared by the invention has good surface activity and antibacterial activity, excellent water solubility and emulsifying ability, and can be used in the field of antibacterial daily chemicals.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a rosin-based tertiary ammonium surfactant and a preparation method and application thereof. Background technique [0002] At present, the requirements for surfactants are getting higher and higher, not only requiring surfactants to have unique properties, but also to have outstanding environmental protection. Due to the relative ease of synthesis and purification, quaternary ammonium cationic surfactants are one of the more researched ones. [0003] Rosin is a rich and renewable natural resource with low price, and its synthetic surfactants generally have good ecological performance, which is in line with the theme of "green environmental protection". Its main component is resin acid, and rosin resin acid is an amphiphile molecule composed of a ternary phenanthrene skeleton structure with excellent lipophilicity and a carboxyl group with weak hydrophilicity. The ternary phenanthre...
