摘　　要：用改变工业萘生产装置初馏塔塔顶温度的方法, 降低酚油中的含萘量, 试验表明, 塔顶温度降至196～199℃后, 可使酚油中的含萘量降至30％左右, 并可相应提高萘的提取率。By the method of reducing overhead temperature of primary distillation column in the technical naphthalene production system, naphthalene content in phenol oil can be lowered. The experiment shows when overhead temperature is reduced to 196～199℃, naphthalene content in phenol oil can be reduced by about 30％, the extracting rate for naphthalene can be increased accordingly.
