Adding a certain compound to certain chemical reactions, such as: 108-70-3, name is 1,3,5-Trichlorobenzene, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 108-70-3, name: 1,3,5-Trichlorobenzene
Potassium nitrate (45.2 g, 447 mmol) was added batch by batch to a stirring solution of fuming sulfuric acid (50%, 250 mL) at 0 C. After the addition was complete, the ice-bath was removed and a condenser wasequipped, and then the mixture was heated to 80 C, at which temperature1,3,5-trichlorobenzene (20.3 g, 112 mmol) was added portionwise. After being heatedfor 18 h at 130 C, the reaction mixture was allowed to cool to room temperature and then poured to 300 ml ice. The resulting solid was washed with water and ethyl ether,respectively. Recrystallization from chloroform provided the product as a white solid(26.5 g, 75 %).
