Triethyleneglycol Divinyl Ether, with the CAS number 765 - 12 - 8, is a high - quality chemical product offered by our factory at a competitive price. It appears as a clear, colorless liquid. The molecular formula of Triethyleneglycol Divinyl Ether is C10H18O4, and its molecular weight is approximately 202.25 g/mol. It has a boiling point in the range of 110 - 120°C at 5 mmHg and a density of about 0.995 g/mL at 25°C. This product is soluble in common organic solvents such as ethanol, acetone, and toluene, which makes it suitable for a variety of chemical reactions and industrial applications.
Triethyleneglycol Divinyl Ether has a wide range of applications in different industries. In the polymer industry, it is used as a cross - linking agent. Cross - linking can improve the mechanical properties of polymers, such as increasing their strength, hardness, and chemical resistance. For example, when used in the production of elastomers, it can enhance the elasticity and durability of the final product. In the field of coatings, this product can be used to formulate high - performance coatings. It can react with other components in the coating system to form a dense and tough film, which provides excellent protection against corrosion, abrasion, and weathering. In addition, it is also used in the synthesis of specialty chemicals. Due to its reactive vinyl groups, it can participate in various chemical reactions, such as radical polymerization, to produce new chemical compounds with specific functions.
When using Triethyleneglycol Divinyl Ether, proper safety precautions should be taken. It is recommended to wear appropriate personal protective equipment, such as gloves and goggles. In a laboratory or industrial setting, the product should be stored in a cool, dry place away from heat sources and direct sunlight. Before use, it is necessary to check the quality and purity of the product. If the product has been stored for a long time, it may be necessary to perform some simple tests to ensure its performance. When using it in a chemical reaction, the reaction conditions, such as temperature, pressure, and reaction time, should be carefully controlled according to the specific reaction requirements. For example, in a radical polymerization reaction, the initiator concentration and reaction temperature need to be optimized to obtain the desired polymer properties.
Case 1: Polymer Production
A polymer manufacturing company used Triethyleneglycol Divinyl Ether as a cross - linking agent in the production of polyurethane elastomers. By adding an appropriate amount of this product, the company was able to significantly improve the mechanical properties of the elastomers. The tensile strength increased by 30%, and the elongation at break also improved. This led to an increase in the market competitiveness of their products, as the improved elastomers were more suitable for high - stress applications such as automotive parts and industrial seals.
Case 2: Coating Formulation
A coating manufacturer incorporated Triethyleneglycol Divinyl Ether into their epoxy - based coating formulation. The resulting coating had a much better corrosion resistance compared to the previous formulation. In a salt - spray test, the coated samples showed no signs of corrosion after 1000 hours, while the un - improved coating started to show corrosion after 500 hours. This improvement in corrosion resistance made the new coating more popular in the marine and construction industries, where long - term protection against corrosion is crucial.
