61683-99-6 - Preparation Method
Open Data Verified Data
- with safrole as raw material can be prepared from Jasmine. 6 parts of potassium hydroxide was added to 10 parts of alcohol and put into an isomerization reactor. The potassium hydroxide was dissolved by stirring and heating to reflux. Then, 6 parts of pure safrole were added to the solution, and the mixture was heated slowly, refluxed and reacted for 15-20h. After completion of the reaction, the mixture was cooled, diluted with water and then distilled off most of the alcohol. The remaining crude isosafrole oil was subjected to vacuum fractionation to remove impurities therein.
- in a glass-lined reaction kettle, 26 parts of distilled water, 11.6 parts of sodium dichromate, and a small amount of P-aminophenyl iodic acid were first charged and dissolved by stirring. After 6.6 parts of isosafrole was added and mixed with stirring at room temperature, 98% of industrial sulfuric acid was slowly added while stirring. Due to the exotherm of the reaction, cold water cooling in the jacket is required, and the rate of addition of sulfuric acid is slow. After the addition of sulfuric acid, the reaction was continued for 0. 5H and then allowed to stand for stratification. The benzene layer was separated and the remaining acidic mixture was extracted once more with 8 parts of benzene at 40 °c. The second extracted benzene liquid was combined, washed and neutralized, and the benzene was distilled off (recovered). The crude acrolein left in the distillation kettle is subjected to vacuum fractionation to obtain semi-solid acrolein. Dissolve it in the same amount of 95% alcohol, slightly heat, so that the ocean is completely dissolved, and the appropriate amount of activated carbon is stirred 0. 5H, and then filtered, cooled, crystallized, low temperature drying, can be obtained.
