Among the series of alkyl polyglucoside, alkyl polyglucoside are particularly effective as a nonionic surfactant for the removal of oily soils. The use of alkyl glycosides in laundry detergents has the following advantages:

It produces rich and delicate foam. Due to the presence of these fine foams, the friction of the laundry, especially fine clothing, such as wool and silk products, in the washing machine is reduced, which is advantageous for fabric protection.

Suitable for cold water washing.

Reduces the irritation of laundry detergent. A laundry detergent equipped with an alkyl glycoside can effectively remove dirt and oil, and has both softness, antistatic property and shrinkage resistance, and can be used normally in hard water.

Alkyl glycosides have been found in recent years to reduce water activity and change the fluid flow state of shale voids, so they were originally used as inhibitors, but the experimental results show that this material has organic drilling fluid after it is added to the drilling fluid. Characteristic, alkyl glycoside can interact with other water-soluble polymers to achieve optimal fluid loss.

Currently, the application to the drilling fluid is mainly methyl glucoside (MEG). In addition, the drilling fluid system such as ethyl glycoside and propyl glycoside is in the indoor research stage. Jiang Juan et al. studied the synthesis and properties of n-propyl glycoside (BEG) and isopropyl glycoside (PEG). Experiments show that BEG and PEG drilling fluid systems have good rheological properties, high rolling recovery, good wetting properties and certain resistance to CaCl2, NaCl and MgCl2. The system is still in the laboratory stage.

In the tertiary oil recovery, the C12-C16APG compound solution was used as the displacement fluid. It was found by experiments that as the alkyl chain grows, the displacement effect of APG is obviously enhanced, and the oil recovery rate can be improved compared with water flooding. . Stefan Iglauer et al. investigated the application of alkyl glycosides in improving oil recovery, focusing on the application of alkyl glycoside components in reducing surface tension and finding alkyl glycoside components in alkyl glycoside-alcohol adjuvant formulations. It can provide a small surface tension and the surface tension is basically independent of salinity and temperature. This alkyl glycoside formula can improve oil recovery in core flooding test, in three surfactant flooding. It can get 85% of the original oil reserves; the contaminated soil contaminated by weathered crude oil is widely distributed in the oilfield and petroleum industry, and the cleaning is much more difficult than the newly polluted soil. Mei Han et al. use alkyl glycosides to pollute the weathered oil near Jilin Oilfield. The soil was studied.
