Hexahydrophthalic anhydride is a chemical with obvious appearance characteristics. It appears as white to off-white crystals with a melting point between 32-34°C, which is a low-melting-point solid. It has good solubility and can be dissolved in solvents such as benzene and acetone, but it should be noted that it is sensitive to humidity, so a dry environment should be maintained during storage and handling.
In terms of density, the density of hexahydrophthalic anhydride is 1.18, which indicates that it is relatively light. Its boiling point is high, reaching 296°C, which means that it is unlikely to exist in gaseous form at room temperature. The flash point is 143°C, which means that there may be a risk of combustion at temperatures above this temperature, so it needs to be handled with caution.
From the perspective of chemical properties, hexahydrophthalic anhydride has good compatibility with epoxy resin in the temperature range of 50~60°C, has low viscosity after mixing, has a long shelf life, and has a mild curing process with low heat release. The cured epoxy resin is colorless and transparent. In addition, hexahydrophthalic anhydride has low toxicity, with an LD50 value of 1200mg/kg, indicating that it is relatively safe under normal conditions of use.
