3,4,5,6-Tetrahydrophthalic anhydride, with the CAS number 2426-02-0, is a high - quality chemical compound. It is a colorless to pale yellow solid with a characteristic odor. This product is known for its high purity and is offered at the best market price.
The molecular formula of 3,4,5,6-Tetrahydrophthalic anhydride is (C_8H_8O_3), and its molecular weight is approximately 152.15 g/mol. It has a melting point in the range of 99 - 102°C and a boiling point around 281°C. The density is about 1.24 g/cm³. It is soluble in organic solvents such as acetone, benzene, and toluene but sparingly soluble in water.
This product has a wide range of applications in different industries:
When handling 3,4,5,6-Tetrahydrophthalic anhydride, proper safety measures should be taken. Operators should wear appropriate personal protective equipment, including gloves, safety glasses, and a respirator if necessary.
In the resin synthesis process, it should be added according to the specific formulation requirements. Usually, it is mixed with other reactants under controlled temperature and pressure conditions. For example, in the production of unsaturated polyester resins, it is reacted with glycols and unsaturated acids in a reactor vessel. The reaction temperature and time should be strictly controlled to ensure the quality of the final product.
When using it in the coating industry, it should be dissolved in suitable solvents and then mixed with other coating components. The mixing ratio and process should follow the technical specifications of the coating formulation.
Automotive Parts Manufacturing: A leading automotive parts manufacturer used 3,4,5,6-Tetrahydrophthalic anhydride - based unsaturated polyester resins to produce fiberglass - reinforced plastic parts. These parts include engine covers and fenders. The high - strength and lightweight properties of the fiberglass - reinforced plastics made from this resin significantly improved the fuel efficiency of the vehicles. The parts also showed excellent resistance to environmental factors such as moisture and chemicals, reducing the maintenance cost of the vehicles.
Marine Boat Building: A boat - building company adopted coatings synthesized with 3,4,5,6-Tetrahydrophthalic anhydride - derived alkyd resins. The coatings provided excellent protection to the boat's hull against seawater corrosion, UV radiation, and mechanical damage. The boats coated with these resins had a longer service life and maintained a good appearance even after long - term use in harsh marine environments.
