use

1. Mainly used to produce raw materials for unsaturated polyester resin, alkyd resin, pesticide malathion, high-efficiency and low-toxic pesticide 4049, and long-acting iodoamine.

2. Determination of reagents for organic compounds with conjugated double bonds. It is also used in synthetic resins, coatings, pesticides, medicine, food, and lubricant additives.

3. Used in organic synthesis, synthetic fiber intermediate. Used as an analytical reagent, such as a reagent for the determination of organic compounds with conjugated double bonds.

4. Used as a curing agent for epoxy resin, the reference dosage is 19-27 parts by mass. Because of its high reactivity and volatility, it is not suitable to be used alone. It is mostly mixed with other acid anhydrides or toughening agents (such as pyromellitic dianhydride). use.
