Abstract: A “green” route to the synthesis of chloromethyldihydrosafrole ［1938-32-5 ］ is reported. Thus, a mixture of 1.00 mol of dihydrosafrole from Cinnamomum P e trophilum Leaves Oil, 1.40 moles of paraformaldehyde and 360ml of 36%hydrochlo ric acid was stirred for 7.0 hours at 70℃ to give 98.6%yield of chloromethyl dihydrosafrole (purity ≥93.4%). 94%of hydrochloric acid can be recovered from the wastewater of chloromethylation reaction by distillation. HCl can be absorb ed by the recovered hydrochloric acid to give ≥36%of hydrochloric acid, which can be used to next chloromethylation. After wastewater from the distillation is treated, CODCr is reduced to 72 mg/L, colority is 40 time, and pH is chan ged to 9. -
