Embodiment 1

[0033] Put the measured 1mmol lauryl polyoxyethylene ether (n=9) into a 50ml round bottom flask, then place the flask in an oil bath heater to heat, and add the measured 1.00mmol benzoyl chloride to the constant pressure drop In the funnel, when the temperature in the flask rises to 55-60°C, stop heating, turn on the agitator, and slowly add benzoyl chloride dropwise; after the dropwise addition, raise the heating temperature to 85-90°C, and react for 3-4 hours , stop stirring, let stand.

Embodiment 2

[0035] Put the metered 1mmol of polyoxyethylene lauryl ether (n=9) into a 50ml round bottom flask, then place the flask in an oil bath heater to heat, and add the metered 1.05mmol of benzoyl chloride to the constant pressure drop In the funnel, when the temperature in the flask rises to 55-60°C, stop heating, turn on the agitator, and slowly add benzoyl chloride dropwise; after the dropwise addition, raise the heating temperature to 85-90°C, and react for 3-4 hours , stop stirring, let stand.

Embodiment 3

[0037] Put the metered 1mmol lauryl polyoxyethylene ether (n=9) into a 50ml round bottom flask, then place the flask in an oil bath heater to heat, and add the metered 1.20mmol benzoyl chloride to the constant pressure drop In the funnel, when the temperature in the flask rises to 55-60°C, stop heating, start the agitator and slowly add benzoyl chloride dropwise; after the dropwise addition, raise the heating temperature to 85-90°C, and react for 3-4 hours. Stop stirring and let stand.

Abstract

A lauryl-polyethenoxy ether benzoate and its synthesis are disclosed. The process is carried out by esterification reacting lauryl-polyethylene glycol with benzoyl chloride in proportion of 1:1.05-1.20 at 85-90 degree for 3-4hrs, washing reactant by 5% sodium carbonate solution for twice, drying and inspection analyzing to obtain final product. It has excellent detersive power, wetting ability and surface reactive compatibility. It can be used for industrial organic raw mterial and alcohol non-ionic surface activator.

Description

technical field [0001] The invention relates to an alcohol-based nonionic surfactant, more specifically to a lauryl alcohol polyoxyethylene ether benzoate surfactant, and belongs to the technical field of organic chemical additives. Background technique [0002] With the advent of the 21st century, the sustainable development of society and its related ecological, environmental, resource, economic and other issues have increasingly become the focus of attention of the international community and have been raised to the height of development strategy. What is more serious is the requirement of environmental protection, prompting the chemical industry to focus on eliminating or reducing the generation of waste from the source, that is, the prevention of original pollution, rather than the treatment after pollution. Many of today's chemical products and their production processes are mostly developed on the basis of the technology of the 1950s. While making contributions to hum...
