Multiple-test tube stirring-rotating type method and device for photochemical reaction

Abstract

The invention relates to a multiple-test tube stirring-rotating type method and device for photochemical reaction. The inner parts of test tubes for photochemical reaction are simultaneously stirred by magneton, the test tubes rotate around a light source and are illuminated in rotating states, the center light source surrounded by the test tubes is filtered by chemical light-filtering liquid or light-filtering sheets, the chemical light-filtering liquid is put into an outer interlayer with a double-interlayer quartz cold trap, the cooling water passes through an inner interlayer, and the light source is placed in the inner cavity of the quartz cold trap. At most 10-20 test tubes of 10-50ml can be simultaneously inserted into the device of the invention to be illuminated; the liquid for photochemical reaction in the test tubes is ventilated to participate in the reaction or is ventilated for protecting; and the invention can ensure the uniformity of the concentration of the reaction solution and the uniformity of the received illumination, can ensure the reliability and the high efficiency of the experimental result, and is especially suitable for measuring kinetic constants such as the quantum yield, the reaction rate and the like of the photochemical reaction.

Description

technical field [0001] The invention relates to a photochemical reaction method and device. In particular, methods and devices for multi-tube stirring-rotation photochemical reactions for research and experimentation. Background technique [0002] Photochemistry is a branch of chemistry that studies permanent chemical changes caused by the interaction of light and matter. Photochemistry involves wavelengths ranging from 100 to 1000 nm. The early research was mainly on photochemical synthesis, such as the synthesis of ozone with oxygen and the synthesis of dianthracene with anthracene, which are still widely used in the synthesis of organic chemicals. After the 1960s, photochemistry has developed from a special synthetic chemistry to the research stage of Mechanistic photochemistry, which has greatly promoted the understanding of the way photochemistry occurs, the nature and laws of chemical changes. [0003] Photochemical reactions are an important way for pollutants to ch...
