Embodiment 1

[0022] Weigh stearic acid and polyethylene glycol 200 with a molar ratio of 1:1 and pour them into a four-necked flask, then add catalyst phosphorous acid (0.2% of the mass of polyethylene glycol) to it, heat to 200°C, and react 3 -5h, when the acid value drops to about 10, add ordinary rosin (the molar ratio of rosin to polyethylene glycol 200 is 1:1), raise the temperature to 270°C and react for 4-8h, when the acid value drops to about 10, the reaction is basically completed.

[0023]

Embodiment 2

[0025] It is basically the same as Example 1, wherein stearic acid can be replaced by any one of palmitic acid and oleic acid, rosin can be replaced by any one of disproportionated rosin and hydrogenated rosin, and polyethylene glycol 200 can be replaced by polyethylene glycol 200. Any one of diol 400, 600, 1000, 2000, 4000.

[0026]

Embodiment 3

[0028] Basically the same as Example 1, the reaction temperature of the first step reaction fatty acid and polyethylene glycol can be 150-220°C: the reaction temperature can be 150°C, 160°C, 170°C, 180°C, 190°C, 200°C, 210°C , 220°C, the reaction temperature of the second step reaction fatty acid polyethylene glycol monoester and rosin is 220-280°C, for example, 220°C, 230°C, 240°C, 250°C, 2,60°C, 2,70°C can be selected , 280°C.

Abstract

The invention discloses a colophony / fatty acid sealing end non-ionic surface active agent and a preparation method thereof. Colophony is monocarboxylic acid containing a three-loop diterpene structure, such as common colophony or disproportionated rosin or hydrogenated rosin; and fatty acid is monocarboxylic acid with a linear chain structure, such as stearic acid or palmitinic acid or oleic acid. The one-pot preparation method comprises the following steps of: firstly, performing esterification on fatty acid and polyglycol to form fatty acid polyethylene glycol monoester, and then carrying out reaction on the fatty acid polyethylene glycol monoester and colophony to generate the colophony polyethylene glycol fatty acid ester, wherein the critical micelle concentration of the prepared surface active agent is 0.01-0.1 mmol / L, and the surface tension range of the surface active agent is 40.7-54.8 mN / m. The novel functional green surface active agent provided by the invention has the high activity of a linear chain surface active agent and the high spreading property of a colophony surface active agent.

Description

Technical field [0001] The present invention involves a new type of green surfactant and its preparation method, especially for a rosin / fatty acid sealing non -ion surfactant and its preparation method. [0002] Background technique [0003] Surface active agent is a kind of two parent, that is, hydrophilic and liquid bases in the molecules.Due to their presence, the nature of the material interface has changed significantly.Surface active agents are divided into cations surface surfactants, anionospense surfactants, and non -ionic surfactants.Non -ionic surfactants have good solubility in water and organic solvents, and have a high patience for changes in solution ion strength and pH value.Because it has a variety of performances such as decentralization, emulsification, foam, wetting, and dissolving, it has important uses in many fields.Most of my country's emulsifier products are based on petrochemical resources, and there are disadvantages of large oil dependence and poor env...
