p-tert-Butylbenzyl mercaptan - Reference Information
| Use | P-tert-butyl benzyl mercaptan is an intermediate for the synthesis of the acaricide pyridaben. |
| production method | the preparation method is to add 18.3g(0.1mol) of p-tert-butyl benzyl chloride, 100g of toluene, 0.5g of tetrabutylammonium bromide and 1.8g of acetic acid (0.03mol) to a four-port reaction flask with a capacity of 300mL, after heating to 50 ℃, 31.7g(0.13mol) of 23% sodium hydrosulfide aqueous solution is added dropwise under stirring. After 30min dropwise addition is completed, the stirring reaction is continued at 50 ℃ for 30min, the reaction is cooled to room temperature, the toluene layer is layered after standing, the toluene layer is washed with water, the toluene is evaporated, and 18.0g of p-tert-butyl benzyl mercaptan with light yellow appearance is obtained by concentration, the purity is 93%, and the synthesis yield is 92%. If the distillation is carried out and the fraction with boiling range of 90~92 ℃/532Pa is collected, the purity of p-tert-butyl benzyl mercaptan can reach 99%. The pure p-tert-butyl benzyl mercaptan is a colorless and transparent liquid with a mercaptan odor, miscible with most organic solvents, and the content of industrial products is 95%. |
