2,5-Norbornadiene Usage

1. Dicycloheptadiene, also known as 2,5-norbornadiene, is a highly liquid, soluble in petroleum ether and insoluble in water. Commercially available products typically contain 500 ppm of 2,6-di-tert-butyl-p-methylphenol (BHT) as a stabilizer. By analyzing the structural characteristics of NBD, it can be found that it has good reaction performance. It can synthesize various organic compounds by addition or substitution reaction in double bond. In solar energy conversion and storage system, photoisomerization of norbornadiene is synthesized. Naphthenes are a very important reaction through which the isomerization reaction between it and its isomers absorbs or releases 69 KJ/mol of light energy. 2. 2,5-norbornadiene is formulated with preservatives together with ethylene biosynthesis inhibitors, which can effectively inhibit the effects of ethylene on plants such as flowers, fruits and vegetables, and prolong the shelf life of plants. This preservative is abroad. develop rapidly.

3. In addition, dicycloheptadiene is also used in various olefin polymerization stereostructure regulators, ligands for homogeneous precious metal catalysts, and high-energy fuels for racing, missiles, and rockets after full hydrogenation.

4. Bicycloheptadiene can be used as an intermediate in prostaglandin synthesis.

5. The bicycloheptadiene sheet can be used to prepare cyclopentadiene pesticides and unsaturated polyester resins. Can be used in the synthesis of optical storage materials.
