Paragraph 0026; 0027; 0031, (2019/04/27)
The invention provides a method for preparing alkyl glycoside. The method comprises the following steps: providing a deep-eutectic solvent as a catalyst, wherein the deep-eutectic solvent consists ofcholine chloride and hydrogen-bond donors, and the structural formula of the choline chloride is shown as the formula (I) in the original specification; performing a reaction on the deep-eutectic solvent, glucose and fatty alcohol, so as to generate the alkyl glycoside, wherein the molar ratio of the choline chloride and the hydrogen-bond donors is 1: 1. Therefore, by utilizing the characteristicsof the deep-eutectic solvent of being uneasy in volatilization and combustion, good in heat stability and solubility, easy in recovery, repeatable in use and the like, the reaction is performed on the deep-eutectic solvent, the glucose and the fatty alcohol to generate the alkyl glycoside, the utilization rate of atoms in a synthesis process is as high as 100%, and the alkyl glycoside is low in toxicity and is biodegradable.

A family of phosphated alkyl oligoglucoside surfactants was prepared by reacting alkyl oligoglucosides with phosphorus oxychloride. The alkyl oligoglucosides were obtained by an usual method in which the glucose is reacted with a fatty alcohol containing 10-18 carbon atoms. These novel phosphated surfactants have been found to exhibit good surface tension, foaming and wetting power. The critical micelle concentration was found to increase with the length of hydrocarbon chain of the surfactant. The surface excess concentration and the interfacial area per surfactant molecule are reported. These phosphated surfactants also exhibit a good performance to improve the whiteness and wetting of cotton fabrics in a hydrogen oxide bleaching system, and they are also found to be more biodegradable than conventional surfactants.
