    • The object of the present invention is, in methods for producing cyclic phenol sulfides, to provide methods for producing a number of more macrocyclic products, which comprise the steps of producing a mixture of cyclic phenol sulfides from an inexpensive raw material in one step without inducing the reduction in yield of a cyclic quatromer; and easily separating and purifying a single component from the mixture of cyclic phenol sulfides.The present invention discloses methods for producing a cyclic phenol sulfide which comprises the step of reacting a phenol compound as a raw material, in a one-step reaction, 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 to obtain a mixture of cyclic phenol sulfide wherein m=4 and at least one kind(s) of cyclic phenol sulfide wherein m=5 to 9, or each separate cyclic phenol sulfide comprised in the mixture.
    • 本发明的目的在于提供环状苯酚硫化物的制造方法,提供多种大环化合物的制造方法,其特征在于,在一个步骤中,从一价廉的原料制造环状苯酚硫化物的混合物, 循环四聚体的产率降低; 并且容易地从环状苯酚硫化物的混合物中分离和纯化单一组分。 本发明公开了一种环状苯酚硫化物的制造方法,其特征在于,在一步反应中,使作为原料的酚化合物与1.7〜2.5摩尔当量的硫和0.25〜0.75摩尔当量的碱金属 试剂,每1mol酚化合物,得到m = 4的环状苯酚硫化物和m = 5〜9的至少一种环状苯酚硫化物或混合物中所含的各自分离的环状苯酚硫化物的混合物。
