Light adjusting mechanism of organic synthesis photoreaction experimental device

Abstract

The invention discloses a light adjusting mechanism of an organic synthesis photoreaction experimental device. The light adjusting mechanism comprises a base and a lamp tube, the base is a cavity with an upper opening, a floating table capable of moving along the horizontal plane is arranged above the base, a vertical lamp tube is fixed in the middle of the floating table, a rotatable rotating ring is arranged between the inner wall of the base and the floating table, a plurality of test tube seat assemblies are circumferentially distributed on the rotating ring, and test tubes can be placed on the test tube seat assemblies; and the periphery of the test tube seat assembly on the base is surrounded by a shell, the shell is higher than the lamp tube and the test tube, and a detachable top cover is arranged above the shell. Compared with the prior art, the test tube can uniformly receive illumination of the lamp tube; when the rotating ring rotates and drives the floating table to rotate through a sliding rod, the central position of the floating table, namely the position of the lamp tube, is always kept unchanged, so that the test tube on the test tube base can rotate around the lamp tube, and the illumination intensity is periodically changed.

Description

technical field [0001] The invention relates to the technical field of a chemical experiment device, in particular to a light adjustment mechanism of an organic synthesis photoreaction experiment device. Background technique [0002] In a photochemical reaction, the reactant molecules absorb light energy, and the ground state of the reactant molecules transitions to an excited state, becoming an activated reactant molecule, and then a chemical reaction occurs. The energy absorbed by a molecule from the ground state to the excited state sometimes far exceeds the energy available for thermochemical reactions. Therefore, organic photochemical synthesis can accomplish many synthetic tasks that are difficult or even impossible for thermochemical reactions. [0003] The photochemical reaction is to make a certain group of the reactant excite the surface of the reactant to promote the reaction through the absorption of photons, and the energy of the reaction product can be higher ...
