Introduction: Photochemistry is a chemical branch of the permanent chemical effect caused by the interaction between light and matter. The substance usually produces a chemical reaction under visible or ultraviolet radiation. There are many differences between the photochemical reaction and the general thermochemical reaction. It is mainly manifested in the fact that the molecular energy distribution in the system is subject to the Boltzmann distribution when the molecules are activated by heating. When the molecules are activated by light, they can, in principle, Selective excitation, the distribution of molecular energy in the system is non-equilibrium distribution. Therefore, the photochemical reaction pathways and products are often different from the ground state thermochemical reaction, as long as the wavelength of light is appropriate, can be absorbed by the material, even at very low temperatures, photochemical reactions can still be carried out. Technical indicators: 1. UV mercury lamp power: 400W; 100-400 watts power adjustable 2. UV wavelength: 365nm 3. Contact temperature sensor, real-time monitoring of reaction temperature, corrosion-resistant coating 4. Rotation speed: 10 r / min 5. Digital tube display: time, temperature 6. Reaction tube: quartz glass tube 7. Volume: 10-30ml, can do 20 parallel reactions at the same time
