    • The present invention discloses a method for continuously producing an oxidized cyclic phenol sulfide which comprises the continuous steps of reacting a para-alkyl phenol compound as a raw material with 1.7 to 2.5 molar equivalent of sulfur and 0.25 to 0.75 molar equivalent of an alkali metal reagent per 1 mol of the phenol compound (the first step); and oxidizing a cyclic phenol sulfide of the formula (2) produced by the above reaction with an oxidizing agent(s) in the same reactor as that of the first step and without taking the cyclic phenol sulfide out of the reactor; wherein R represents a straight or branched alkyl group having 1 to 6 carbon atoms, and m is an integer from 4 to 8, to obtain an oxidized cyclic phenol sulfide of the formula (3) (the second step): wherein R represents a straight or branched alkyl group having 1 to 6 carbon atoms, m is an integer from 4 to 8, and n is 1 or 2.
    • 本发明公开了一种连续生产氧化环状苯酚硫化物的方法,该方法包括以对数烷基酚化合物为原料与1.7〜2.5摩尔当量硫和0.25〜0.75摩尔当量碱金属试剂的连续步骤 每1mol酚化合物(第一步); 和在与第一步骤相同的反应器中用氧化剂氧化由上述反应产生的式(2)的环状苯酚硫化物,而不将环状苯酚硫化物从反应器中取出; 其中R表示具有1至6个碳原子的直链或支链烷基,m为4至8的整数,以获得式(3)(第二步)的氧化环状苯酚硫化物:其中R表示直链 或碳原子数为1〜6的支链烷基,m为4〜8的整数,n为1或2。
