PG has low surface tension, no turbidity point, adjustable HLB value, strong wetting force, good detergency, rich and delicate foam, excellent compatibility, non-toxic, harmless, no irritation to the skin, rapid and thorough biodegradation, can be mixed with any type of surfactant, synergistic effect is obvious;With strong broad-spectrum antibacterial activity, the product has significant thickening effect, easy to dilute, no gel phenomenon, easy to use;And strong alkali resistance, acid resistance, hard water resistance, salt resistance.Therefore, APG can be used as the main raw material of hair shampoo, shower gel, facial cleanser, laundry detergent, hand sanitizer, dishwashing liquid, vegetable and fruit detergent and other daily chemicals, and used in soap powder, phosphorus-free detergent, phosphorus-free detergent and other synthetic detergents;It can be used as emulsifying dispersant of food, pesticide and silicone oil, synergistic agent of pesticide and herbicide, anti-fogging agent of agricultural film and plastic auxiliary agent;Can be used in medicine, biological engineering, industrial cleaning, fire agents, textile additives, coatings, photographic materials, leather, oil recovery, mineral processing, rubber and plastic, energy and other fields.

  Alkyl indican was found to have lower water activity in recent years, change the fluid flow state of shale gap, so at the beginning of Z is used as inhibitor used, but the experimental results show that the material added to the drilling fluid, has the characteristics of organic drilling fluid, alkyl indican can interact with other water-soluble polymers and achieve Z better filtration effect.

  At present, methyl glucoside (MEG) is mainly used in drilling fluid.In addition, other drilling fluid systems, such as ethyl glycoside and propyl glycoside, are in the stage of indoor research. Jiang Juan et al studied the synthesis and properties of n-propylglycoside (BEG) and isopropyl glycoside (PEG). The experimental results show that BEG and PEG drilling fluid systems have good rheological properties, high rolling recovery, good wettability and certain resistance to CaCl2, NaCl and MgCl2 contamination. The systems are still in the laboratory stage.

  In tertiary oil recovery, c12-C16APG complex solution is used as displacement solution. Experimental observation shows that with the growth of alkyl chain, THE displacement effect of APG is obviously enhanced, and compared with water flooding, it can improve oil recovery.Stefan Iglauer et al. investigated the application of alkyl glycosides in improving oil recovery, focusing on the application of the alkyl glycosides component in reducing surface tension and found that the alkyl glycosides component in the alkyl glycoside-alcohol additive formula can provide a small surface tension and the size of the surface tension is basically independent of salinity and temperature. This alkyl glucoside formula can improve oil recovery in core displacement tests, achieving 85% of the original oil reserves in tertiary surfactant displacement.The soil contaminated by weathered oil widely exists in oil fields and petroleum industry, and it is much more difficult to clean up than the newly polluted soil. Mei Han et al studied the soil contaminated by weathered oil near Jilin oil field with alkyl glycosides.Compared with APG0810, APG1214 is more effective than APG1214 in removing crude oil, which also shows its feasibility in cleaning weathered oil contaminated soil.After the addition of inorganic salts, especially alkaline salts, in APG1214, the removal efficiency of crude oil is significantly improved.In this paper, APG1214, Na5P3O10, Na2CO3, Na2SiO3 as the main components to make a washing formula, through the experiment to establish the optimal process conditions (temperature 80℃, washing time 30min, speed 350 RPM, solution/soil concentration of 10mL /g).Under these conditions, the crude oil removal efficiency reached 97%, which provided a promising method for treating weathered oil contaminated soil and made it easy to reconstruct the ecological function of washed soil.

  Weathered petroleum A type of petroleum formed by a series of geological processes including transport, deposition, and diagenesis of materials produced by weathering.Mostly distributed in sedimentary rocks.

  Sedimentary rocks make up only 5% of the lithosphere by volume, but they cover 75% of the land, and the ocean floor is almost entirely covered by sedimentary rocks or sediments.Sedimentary rocks are not only extremely widespread, but also record the long process of crustal evolution.The oldest rocks in the earth's crust are known to be 4.6 billion years old, while the oldest rocks in the sedimentary lithosphere are 3.6 billion years old (Kola Peninsula, Soviet Union).Sedimentary rock contains a large number of sedimentary minerals, such as coal, oil, natural gas, salt and so on, and iron, manganese, aluminum, copper, lead, zinc and other mineral deposits also occupy a large proportion.At the same time, the distribution area of sedimentary rocks is the main site of hydrogeology and engineering geology.Therefore, the study of sedimentary rocks is of great significance to the development of geological theories and the search for abundant sedimentary minerals as well as the work of hydrogeology and engineering geology.
