Cis-1,2,3,6-Tetrahydrophthalic Anhydride, with the CAS number 935 - 79 - 5, is an important industrial chemical. This product is supplied directly from the factory, ensuring high - quality and a competitive price. It appears as a colorless to pale yellow liquid or a solid, depending on the temperature. The molecular formula of Cis - 1,2,3,6 - Tetrahydrophthalic Anhydride is C₈H₈O₃, and its molecular weight is approximately 152.15 g/mol. It has a melting point range of around 32 - 34°C and a boiling point of about 257°C. The density is roughly 1.20 g/cm³ at 25°C. It is soluble in common organic solvents such as acetone, benzene, and toluene.
Cis - 1,2,3,6 - Tetrahydrophthalic Anhydride has a wide range of applications in different industries. In the polymer industry, it is used as a curing agent for epoxy resins. Epoxy resins cured with this anhydride have excellent mechanical properties, chemical resistance, and heat resistance, making them suitable for coatings, adhesives, and composite materials. In the paint and coating industry, it can improve the hardness, gloss, and adhesion of coatings. In the pharmaceutical industry, it can serve as an intermediate in the synthesis of certain drugs. Additionally, it is used in the production of plasticizers, which can enhance the flexibility and durability of plastics.
When using Cis - 1,2,3,6 - Tetrahydrophthalic Anhydride, proper safety precautions should be taken. Wear appropriate protective clothing, gloves, and eye protection. In a laboratory or industrial setting, it should be handled in a well - ventilated area. For the curing of epoxy resins, the appropriate ratio of the anhydride to the epoxy resin needs to be determined according to the specific requirements of the application. Generally, the mixing ratio is based on the equivalent ratio of reactive groups. The mixture should be thoroughly stirred to ensure uniform curing. After mixing, the resin system should be poured or applied to the desired substrate within the pot - life. The curing process usually requires heating to a certain temperature for a specific period of time to achieve the best performance.
Case 1: Epoxy Coating for Metal Protection
A metal manufacturing company needed a high - performance coating to protect its metal products from corrosion. They used Cis - 1,2,3,6 - Tetrahydrophthalic Anhydride as a curing agent for an epoxy resin - based coating. The coating was applied to the metal surface after proper surface treatment. After curing at 120°C for 2 hours, the coating showed excellent adhesion to the metal. Salt spray tests indicated that the coated metal had a significantly longer corrosion - resistant life compared to uncoated metal. The hardness of the coating was also high, providing good scratch resistance.
Case 2: Composite Material for Aerospace Applications
An aerospace company was looking for a lightweight and strong composite material. They used Cis - 1,2,3,6 - Tetrahydrophthalic Anhydride to cure an epoxy matrix for carbon fiber composites. The carbon fibers were impregnated with the epoxy - anhydride mixture and then cured under high - pressure and high - temperature conditions. The resulting composite material had high strength - to - weight ratio, good heat resistance, and excellent fatigue performance, meeting the strict requirements of aerospace applications.
