production method | there are 3 synthesis processes for p-tert-butyl benzyl chloride. (1) The tert-butyl benzene chloromethylation method puts tert-butyl benzene, paraformaldehyde, acetic acid, hydrochloric acid and catalyst zinc chloride into the reactor, stirred and heated to 85 ℃, slowly added phosphorus trichloride, reacted at this temperature for 8h, cooled, and released the lower aqueous solution. The organic layer is dried with anhydrous sodium carbonate, and then rectified in a rectification kettle. The fraction at 65~100 ℃(4.40kPa) is cut into tert-butyl benzene, which can be recycled and applied. The fraction at 120~125 ℃(4.40kPa) is p-tert-butyl benzyl chloride. When the feeding amount is 13.4g, the product amount is 8.8g, the recovery amount is 5.5g, and the yield is 88%. (2) p-tert-butyl toluene chlorination method p-tert-butyl toluene is prepared by reacting with ethyl chloroformate. The p-tert-butyltoluene was dissolved in 100mL chlorobenzene, at 25 ℃, the ethyl chloroformate was added dropwise in 20min, and the temperature was raised to 55 ℃ for 6h. At the end of the reaction, add 30% sulfuric acid aqueous solution to the obtained reaction solution, react at 40 ℃ until the end of CO2, carry out hydrolysis reaction, then cool the hydrolysate, divide it into organic layer and water layer, wash the organic layer twice with water, dry with anhydrous sodium sulfate, evaporate chlorobenzene under reduced pressure, and then collect 115~116 ℃(2.67kPa) fractions under reduced pressure to obtain the product with a yield of 71.1%. There are 3 synthesis methods. 1. The tert-butanol method is obtained by chloromethylation of tert-butylbenzene. Put tert-butylbenzene, hydrochloric acid, paraformaldehyde, zinc chloride and glacial acetic acid into the reaction pot, add phosphorus trichloride dropwise at 65 ℃, and stir at 65-70 ℃ for 7 hours. Then cool to 30 ℃, take the upper benzyl chloride crude, remove hydrogen chloride, dehydration filtration, reduced pressure distillation, collect 124-132 ℃(3.33kPa) fraction, that is, to tert-butyl chloride benzyl. 2. tert-butyl benzene chloromethylation method 3. p-tert-butyl toluene chlorination method |
