Adding a certain compound to certain chemical reactions, such as: 24599-58-4, name is 2,5-Dimethoxytoluene, belongs to ethers-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 24599-58-4, Computed Properties of C9H12O2
Preparation of 2,5-dimethoxy-4-methylacetophenone. 1 mol (152 g) of 2,5-dimethoxytoluene is introduced, whilst stirring, into 230 ml of acetyl chloride at -10 C. 160 g of aluminium chloride are then added in the course of 3 hours, whilst stirring and keeping the temperature of the reaction medium at between -10 and 0 C. When the addition has ended, the mixture is stirred for a further 3 hours at between -10 and 0 C. The reaction medium is then poured onto 1 kg of crushed ice to which 110 ml of hydrochloric acid (d=1.19) have been added. After a few hours, the reaction product which has precipitated is filtered off. After washing with water, a 2 N solution of sodium hydroxide and then again with water, the 2,5-dimethoxy-4-methylacetophenone is recrystallized from ethanol. After drying in vacuo, it melts at 75 C.
