Description of the Related Art It is known that, in order to produce a bisphenol compound, an excess monohydric phenol compound is mixed with a carbonyl compound and the condensation reaction is carried out in the presence of an acid catalyst. It is also known to use a strong acid type ion exchange resin as a catalyst in this reaction. When the reaction is carried out using this strong acid type ion exchange resin as a catalyst, the composition of the reaction product obtained varies depending on the type of the catalyst. For example, a catalyst with a low production rate of by-products is likely to be poisoned by water during the reaction,
There is a problem that the reaction activity is lowered and the maximum conversion of the carbonyl compound is lowered. On the other hand, a catalyst that is less susceptible to water poisoning has a higher maximum conversion of carbonyl compounds, but in this case, there is a problem that the production rate of by-products increases.

お、本明細書でいう樹脂の架橋度とは、ジビニルベンゼ
ンの如き架橋剤の含有率(重量%)を意味する。In the present invention, a strong acid type ion exchange resin is used as a catalyst in the above reaction. Examples of the strong acid type ion exchange resin include sulfonated styrene-divinylbenzene copolymer, sulfonated crosslinked styrene polymer, phenol-formaldehyde-sulfonic acid resin and benzene-formaldehyde-sulfonic acid resin. All of these resins have a crosslinked structure and are insoluble. In the present invention, when these strong acid type ion exchange resins (hereinafter, also simply referred to as resins) are used as catalysts, at least two kinds are used with respect to their basic structures. The first resin A used in the present invention has a gel type structure, and the second resin B has a porous type structure. The gel type resin A has a low degree of crosslinking of less than 10%, preferably 5% or less, and the second porous type resin B has a degree of crosslinking of 10% or more, preferably 15% or more. It is a degree. In the study of the present inventors, when the gel type resin A is used, the diffusion rate of the reaction components into the resin is high,
Although it has an advantage that the production rate of by-products is low, it has a problem that it is easily poisoned by water and the maximum conversion rate of the carbonyl compound is low. On the other hand, when the porous resin B is used, it is poisoned by water. It has the advantage that it is hard to receive and the maximum conversion rate of the carbonyl compound is high, but the diffusion rate of the reaction products to the outside of the resin is slow, and the reaction time until the maximum conversion rate is reached is short, It turns out that there is a problem of high production rate of living things. Then, when the monohydric phenol compound and the carbonyl compound react with each other, the present inventors first contact the raw material liquids with the gel-type resin A to carry out the reaction, and then the obtained reaction product is porous. It has been found that the bisphenol compound can be produced at a high reaction rate as a whole, with a high conversion rate of a carbonyl compound, and with a low byproduct formation rate by contacting with a resin B of a mold to cause a reaction. The degree of crosslinking of the resin as used herein means the content (% by weight) of a crosslinking agent such as divinylbenzene.
