Reaction Conditions:
Stage #1: succinic acid anhydridewith aluminum (III) chloride in n-heptane at 25; for 0.166667 h;
Stage #2: m-xylene in n-heptane at 25; for 0.5 h;
Steps:
1 Example 1 Synthesis of 4-dimethylphenyl-4-oxobutanoic acid
a) Add 20g of succinic anhydride and 100g of heptane to a 500mL single-necked flask, quickly add 70g of anhydrous aluminum trichloride, mix and stir evenly, keep the reaction temperature at 25°C, and react for 10 minutes to obtain a mixed solution;b) Add 45 g of xylene to the mixed solution, continue the reaction, keep the reaction temperature at 25°C, and react for 30 minutes to obtain a reaction solution;c) Slowly add 200 mL of deionized water to the reaction solution and stir, and then separate into oil phase and water phase after standing, and separate the oil phase;d) Distilling the oil phase under reduced pressure at 95°C to obtain the product 4-dimethylphenyl-4-oxobutanoic acid.After acid-base titration and nuclear magnetic resonance detection, 4-dimethylphenyl-4-oxobutanoic acid prepared in Example 1 of the present invention has the following structure: The purity of 4-dimethylphenyl-4-oxobutanoic acid prepared in Example 1 of the present invention reached 98%, and the yield reached 95%.
