CN97196512.9 discloses a method for improving oil and gas recovery from underground formations, which includes injecting at least one monoalkyl ether of polyethylene glycol into the formation, preferably in the form of an aqueous solution, wherein the alkyl ether is The base has 3-5 carbons and polyethylene glycol contains 3-6 ethylene oxygen units, such as triethylene glycol monobutyl ether. Particularly preferred are mixtures containing the above-mentioned alkyl ethers and at least one monoalkyl ether of mono- or diethylene glycol, for example triethylene glycol monobutyl ether, tetraethylene glycol butyl ether, pentaethylene glycol butyl ether. A mixture of ether and diethylene glycol butyl ether. The method of the present invention can be applied to well injection treatments such as water plugging, sand consolidation, sandstone acidification and various methods of improving oil recovery such as tertiary oil recovery.

CN201711112289.6 discloses a borate ester base fluid for high-grade brake fluid, which relates to motor vehicle brake fluid. Triethylene glycol butyl ether borate synthesized by the reaction of triethylene glycol butyl ether and boric acid. The water content of the borate ester base fluid for high-grade brake fluid is 310°C. , the purity of the triethylene glycol butyl ether borate is >85%. It means that triethylene glycol butyl ether borate can be used as the base fluid of the only borate ester component, which can be formulated with conventional diluents and additives for brake fluids to produce high-grade brake fluids with different quality indicators. In the brake fluid formula of the high-grade brake fluids with different quality indicators, the component mass percentage of the borate ester base fluid is: 10% to 80% in HZY4 brake fluid; 10% to 80% in HZY5 brake fluid. 50% to 80%; HZY6 brake fluid accounts for 50% to 80%.

CN201710736.5 discloses a method for preparing high-strength cement polystyrene bricks. Polyphenylene and triethylene glycol butyl ether solution are stirred, imidazoline and polyvinyl butyral are added in sequence and stirred to prepare mixture A. ; Mix cement and bijiu solution, add mixture A, process in an ultrasonic oscillator for 30-35 minutes, then add tartaric acid solution, stir, place in a mold, pour, demould, and cure to prepare cement polystyrene bricks. The cement polystyrene brick prepared by the invention has greatly improved compressive strength, good thermal insulation performance, high fire protection level, and excellent water resistance, durability and frost resistance.

CN201710041445.8 discloses a PET-polyamide barrier material and its preparation method and application. The barrier material is composed of the following raw materials in parts by weight: 85-95 parts of polyamide, polyethylene terephthalate glycol 60-70 parts of ester, 13-21 parts of ocher, 18-26 parts of triethylene glycol solvent dye manufacturer butyl ether, 5-13 parts of casein, and 31-39 parts of tetrabutyl titanate. Polyamide, ocher and tetrabutyl titanate are mixed and crushed, heated and stirred, then deionized water is added, heated and stirred to prepare mixture A; polyethylene terephthalate is crushed, and then mixed with casein and sodium hydroxide The solution is mixed, heated and stirred, and then a triethylene glycol butyl ether solution is added, heated and stirred to obtain mixture B; mixture A and mixture B are mixed, ultrasonic treated, heated and cast to obtain the mixture. The invention has the characteristics of high barrier properties, high toughness, excellent mechanical properties, low production cost, and has very broad application prospects in automobile fuel tanks and other fields.

CN201710020533. 30-40%, diethylene glycol 5-15%, triethylene glycol butyl ether 5-10%, tetraethylene glycol butyl ether 5-10%. Add diethylene glycol, triethylene glycol butyl ether, tetraethylene glycol butyl ether, and triethylene glycol methyl ether into a clean, dry batching pot according to mass percentage; start stirring, and then add polyethylene glycol.The brake fluid is obtained after stirring for 50-70 minutes. The automobile brake fluid provided by the present invention has a very high equilibrium reflux boiling point, and the equilibrium reflux boiling point can reach more than 270°C, while it is difficult for general alcohol ether formulas to reach 250°C. The invention has excellent water resistance and the wet boiling point can reach above 190°C. The invention has good anti-rust performance and does not require the addition of additional corrosion inhibitors.

CN201410798911.3 discloses a preparation method and use of a high-gloss, high-leveling water-based coating additive, which belongs to the field of coating additives. The problem to be solved by the present invention is to provide an environmentally friendly film-forming aid that can improve the gloss and leveling performance of water-based coatings, reduce the minimum film-forming temperature, and has low toxicity. The inventors conducted in-depth research and found that: triethylene glycol butyl ether and dipropylene glycol methyl ether acetate have the characteristics of improving leveling and adjusting the drying speed of paint films in water-based resins. The boiling point of triethylene glycol butyl ether is 283°C. According to China’s definition of VOC, triethylene glycol butyl ether has been excluded from the VOC range. It is possible to use triethylene glycol butyl ether as a film-forming aid to produce “zero” VOC products. Water-based coatings, especially triethylene glycol butyl ether, are found to be a slow-drying film-forming additive, and it is also a good water-phase co-solvent, which can improve the rheological properties of the coating and have better flow on the substrate. Flatness, can improve adhesion to smooth surfaces. Dipropylene glycol methyl ether acetate has a boiling point of 205°C. It is a colorless, low-toxic liquid. It is a good solvent with a mild ester odor and a medium evaporation rate.
