Embodiment 1

[0026]

[0027] First, add 60.00g (0.100mol) AEO (R is C12~14, n=9) and then add 23.4g (0.100mol) α-pinene-Malay The acid anhydride adduct (TMA) was heated with stirring and reacted at 70°C for 3 hours to finally obtain a clear and transparent product C12-14 acid fatty alcohol ether succinate surfactant with a measured yield of 94.4%. Add 1mol L -1 111.53mL of NaOH solution, the pH of the solution was 7.0 at this time, and the clear and transparent product C12~14 sodium salt type fatty alcohol ether succinate surfactant S1 was obtained, chemical analysis (potentiometric titration, using 0.1mol L -1 NaOH solution titration) measurement, the active matter content is 42.7%.

Embodiment 2

[0029]

[0030] First, add 50.84g (0.100mol) of AEO (R is C12~14, n=7) mixed uniformly into a three-necked flask with a thermometer and a stirrer, and then add 24.6g (0.105mol) of α-pinene-malay Anhydride adduct (TMA), heated under stirring conditions, reacted at 90°C for 2 hours, and finally obtained a clear and transparent product C12-14 acid fatty alcohol ether succinate surfactant, the yield was determined to be 96.6% . Add 1mol L -1 109.21 mL of NaOH solution, the pH of the solution was 7.1 at this time, and the clear and transparent product C12-14 sodium salt type fatty alcohol ether succinate surfactant S2 was obtained, and the active matter content was 39.0%.

Embodiment 3

[0032]

[0033] First, add 42.03g (0.100mol) AEO (R is C12-14, n=5) and then add 24.6g (0.105mol) α-pinene-malein to a three-necked flask with a thermometer and a stirrer Anhydride adduct (TMA), heated under stirring conditions, reacted at 90 ° C for 2 hours, and finally obtained a clear and transparent product C12-14 acid fatty alcohol ether succinate surfactant, the yield was determined to be 97.6% . Add 1mol L -1 109.21 mL of NaOH solution, the pH of the solution was 7.1 at this time, and the clear and transparent product C12-14 sodium salt type fatty alcohol ether succinate surfactant S3 was obtained, and the active matter content was 36.37%.

Abstract

The invention discloses a fatty alcohol ether alpha-pinene-maleic anhydride addition acid surfactant and a preparation method thereof, the surfactant is prepared by the following steps: carrying out acid anhydride alcoholysis reaction on fatty alcohol ether and alpha-pinene-maleic anhydride adduct, and salifying to obtain the corresponding novel fatty alcohol ether carboxylic acid (salt) surfactant. The surfactant is easy to synthesize, easy to degrade, green and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of surfactants, in particular to a fatty alcohol ether α-pinene-maleic anhydride addition acid and salt surfactant and a preparation method. Background technique [0002] Alcohol ether carboxylate series products (AEC) have both the comprehensive performance advantages of anionic and nonionic surfactants, integrating mildness, safety in use, and easy biodegradability. They are called 21 together with the sugar-based surfactant APG Century's green active components meet the requirements of sustainable development and are currently recognized as functional new products in the world. They have a wide range of applications and can be used as good detergents, wetting agents, dispersants, foaming agents, mildness improvements Agents, viscosity reducers and catalysts are used in cosmetics, household and industrial cleaning, textiles, printing and dyeing, petroleum, chemical, pharmaceutical, health and epidemic prev...
