13-Difluorobenzene CAS No372-18-9

Application

high amounts of solid waste and sodium salt are created by the reaction during the creation of 1,3-difluorobenzene; the wastewater is difficult to treat and high in volume, and the intermittent production efficiency is low. In this article, 1,3-difluorobenzene is made by nitrification, fluorination, chlorination, and dechlorination processes using dichlorobenzene as the starting material. This synthesis route's raw ingredients are widely accessible. In order to circumvent the laborious procedure, the fluorination reaction uses the halogen exchange fluorination method. Diazotization reaction; the other reactions are more common and simple to understand.

product-735-137

Procedure for the experiment: Fill a three-necked flask with 2,4-difluorochlorobenzene, methanol, trilaurylamine (TDA), and activated carbon supported metal palladium (5% Pd/C) catalyst. Turn the temperature up to 100°C, add hydrogen, and let the mixture react for three hours. Following the completion of the reaction, the product is heated to a filtering temperature, diluted Na2CO3 solution and water wash until it becomes neutral, and then it is distilled to produce 1,3-difluorobenzene, a colorless liquid with a boiling point of 83°C and a water content of 98.5%. Gas chromatography was used in the experiment to examine the reaction product content in each step.
