[0011] Example: Take 20g of dimethyl fumarate and put it in a beaker, then place the ultraviolet lamp on the inner wall of the beaker vertically, and seal the mouth of the beaker; connect the power supply of the constant temperature water bath heater, adjust the temperature at 25°C, and then seal it well Put the beaker into a water bath and heat it. After the dimethyl fumarate in the beaker is all sublimated and a lot of smoke is generated, turn on the ultraviolet lamp. The dimethyl fumarate gas is irradiated by the ultraviolet lamp to immediately generate cyclobutane tetracarboxylic acid. Proceed normally; after 30 minutes of reaction, the smoke in the beaker disappears and no solids are generated on the inner wall of the beaker, turn off the ultraviolet lamp, take the beaker out of the thermostatic water bath heater, turn off the power of the thermostatic water bath heater, and place the beaker in In a fume hood, remove the seal of the mouth of the beaker, and collect the soli...
