Definitions
- the present invention relates to a dihydroxydiphenyl comprising 4,4'-dihydroxydiphenylsulfone (hereinafter, also referred to as 4,4'-integral) and 2,4'dihydroxydiphenylsulfone (hereinafter, also referred to as 2,4'-isomer)
- the present invention relates to a method for producing an enylsulfone isomer mixture. Background technology
- trihydroxytriphenyldisulfone (hereinafter also referred to as tri-form) is often produced as a by-product.
- This tri-isomer is contained in a large amount in the residue when dihydroxydiphenyl sulfone is purified, but has no utility and has conventionally been treated as waste. Disclosure of _
- An object of the present invention is to convert trihydroxytriphenyldisulfone into useful 4,4'-dihydroxydiphenylsulfone and 2,4'-dihydroxydiphenylsulfone, thereby producing a dihydroxydiphenylsulfone isomer mixture. It is to provide.
- the present invention provides a method for producing a mixture of 4,4′-mono and 2,4′-dihydric xyldiphenylsulfone isomers as shown below.
- a method for producing a mixture of 4,4'-mono- and 2,4'-dihydroxydiphenylsulfone isomers which comprises heating trihydroxytriphenyldisulfone in the presence of a phenol and an acid catalyst.
- a mixture of dihydroxydiphenylsulfone isomers containing trihydroxytriphenyldisulfone is heated in the presence of a phenol and an acid catalyst, wherein the 4,4′-mono and 2,4′-dihydroxydiphenylsulfone isomers are heated.
- the tri-form of the raw material in the present invention is represented by the general formula (1):
- dihydroxydiphenylsulfone isomer mixture containing a tri-form may be used as a raw material.
- Isomers of dihydroxydiphenylsulfone include 4,4'-integral and 2,4'-integral. This mixture of isomers may be obtained as crude dihydroxydiphenylsulfone in the production of dihydroxydiphenylsulfone.
- the amount of the phenol used is preferably 2 times by weight or less, more preferably 0.1 to 1 time by weight, based on the raw material tri-form or tri-form-containing dihydroxydiphenyl sulfone isomer mixture. However, since phenol also acts as a reaction reagent, it is preferable to use it in an amount of 0.23 times by weight or more based on the tri-form.
- Examples of the acid catalyst used in the present invention include aromatic mono-, di-, trisulfonic acids, methanesulfonic acid, ethanesulfonic acid, and the like such as benzenetrisulfonic acid, benzenedisulfuric acid, benzenesulfonic acid, toluenesulfonic acid, and phenolsulfonic acid.
- acids and inorganic acids such as sulfuric acid. Among them, aromatic mono-, di-, trisulfonic acids and inorganic acids are preferable, and benzenedisulfonic acid, sulfuric acid and the like are more preferable.
- the amount of the acid catalyst to be used is preferably 20 mol% or less, more preferably 1 to 10 mol%, based on the raw material tri-form or tri-form-containing dihydroxydiphenyl sulfone isomer mixture.
- Solvents may or may not be used. When a solvent is used, it is preferable to use a heat-resistant and acid-resistant solvent such as sulfolane.
- the reaction temperature is preferably 160 ° C or higher, more preferably 170 to 210 ° C. If necessary, the reaction may be performed under pressure.
- the reaction time is not particularly limited, but is preferably 0.1 to 20 hours, and more preferably 1 to 10 hours.
- the 4,4'- and 2,4'-dihydroxydiphenylsulfone isomer mixtures which are the object of the present invention, contain essentially no tri-form in principle.
- the tri-isomer may be contained within a range that does not hinder the separation and purification of the 4,4′-isomer or 2,4′-isomer from the dihydroxydiphenylsulfone isomer mixture.
- a dihydroxydiphenylsulfone isomer mixture containing substantially no tri-form can be obtained by repeating the method of the present invention.
- 4,4′-mono and 2,4′-dihydroxydiphenyl sulfone isomer mixtures obtained according to the present invention 4,4′-integration and 2,4′-integration can be obtained by a known separation and purification method.
- the tri-isomer can be converted into a useful 4,4′-isomer and 2,4′-integral to produce a dihydroxydiphenylsulfone isomer mixture.
