Definitions
- the present invention relates to a method for producing an aryl ether of a linear polyol, which is industrially practical and high in yield.
- Related technology
- Japanese Patent Application Laid-Open No. 57-81418 discloses a method using tetrabutylammonium acid sulfate as a phase transfer catalyst. This method has many industrial disadvantages in view of the need for a catalyst removal step and the necessity to take measures against the incorporation of the catalyst or its debris into the product.
- linear polyols have extremely high hydrophilicity, solvents that can dissolve linear polyols at practical levels are substantially limited to water. Attempts to react linear polyols with aryl halides and alkali metal hydroxides under reaction conditions in the absence of water at all do little or no progress at all. Therefore, the linear polyol is dissolved in water to advance the reaction. However, at the beginning of the reaction, the contact between the linear polyol and the aryl halide is poor, and the reaction does not easily proceed. Even when an accelerator such as aryl alcohol is used, the reaction is extremely difficult to proceed as compared with a branched polyol such as pentaerythritol, and a linear polyol is used. It has been difficult to produce polyol allyl ethers on an industrially practical level.
- Japanese Patent Publication No. 4-4303 discloses that when producing an aryl ether of pentaerythritol from pentaerythritol and aryl chloride, the water in the system is reduced when the reaction reaches a stage where the reaction proceeds promptly.
- a method for distilling off is disclosed. However, this method can be successfully used for branched polyols such as pentaerythritol, and even when this method is applied to linear polyols, the yield and the solubility of residual linear polyols are poor. Based on the complexity of the post-process, the distribution of the number of acylated products and the control of the average number of acylated products, and the overall reaction time were not sufficient. Summary of the Invention
- the present inventors diligently study a method for producing an aryl ether of a polyol from a linear polyol compound, which is excellent in productivity in industrial practical use, has a high raw material conversion rate, and a high product yield. did.
- the present inventors have carefully observed result in extent E of reacting Arirukuroraido without discharging water at reflux only, with respect to 1 mole of the hydroxyl groups of the straight-chain polyol compound, 14 mol Arirukuroraido 0/0
- a sufficient amount of oil layer is rapidly formed by the hydrophobization due to the arylation, the raw material sorbitol is sufficiently reduced at the time of the parentheses, and even if the process proceeds to the following dehydration step, it is practically final And completed the present invention.
- the present invention provides a compound represented by the general formula (1):
- n is an integer of 2 to 6.
- a process for producing an aryl ether of a polyol characterized in that, after the addition of the aryl halide to the reaction system, the discharge of water to the outside of the reaction system is started.
- the method of the present invention is generally carried out by adding arinolenolide to a reaction vessel (or reaction zone) charged with the entire amount of the linear polyol compound.
- n is preferably 2 to 4.
- linear polyol compounds are linear bran alcohols, especially erythritol, xylitol and sorbitol.
- aryl halides are aryl chloride and aryl bromide.
- Al-li metal hydroxide examples of metal hydroxides are sodium hydroxide, sodium hydroxide, and hydroxide hydroxide.
- the aryl etherification reaction of the linear polyol compound is carried out in a reaction system (reaction vessel) in which the total amount of the linear polyol compound to be reacted is present. , Preferably done by adding a metal.

- the addition of aryl halide may be carried out dropwise, or the total amount of aryl halide may be divided into several (for example, 3 to 20) small portions, and the small portions may be sequentially added and added. Is also good.
- an amount of water that dissolves the linear polyol at the reaction temperature is present during the period from the start of the aryl ethereal reaction to the start of discharging water out of the system. It does not exclude that at least part or all of the aryl halide used is present at the start of the aryl etherification reaction.
- water may be added so that all of the linear polyol compound is dissolved at the reaction temperature. Prior to the initiation of the aryl ethereal reaction, it is preferable that water is present in such an amount that all the linear polyol compounds are dissolved at the reaction temperature. Water may be added as needed during the course of the reaction.
- the amount of water present in the reaction system based on the total molar number of hydroxyl groups contained in the straight-chain Porioruihi compound, 2 0 mol% or more, for example 2 0-2 5 0 mole 0/0, if further illustrated 100-220 mol. /. And in particular 140 to 180 mol%.
- the amount of water is such that the linear polyol compound dissolves, the aryl etherification reaction speed is high.
- the amount of the alkali metal hydroxide introduced into the reaction system before the water starts to be discharged out of the system is not particularly limited, but is based on the total number of moles of the hydroxyl groups contained in the linear polyol compound. , 26-: L00 mol. /. , For example 28 to 75 monole%, especially 28 to 6
- the required amount of the alkali metal hydroxide may be added all at once before starting the reaction, or may be added as needed during the course of the reaction.
- the alkali metal hydroxide to be added may be either solid or aqueous.
- the alkali metal hydroxide is added in the form of an aqueous solution in which the alkali metal hydroxide is dissolved in water. Water is not discharged out of the reaction system until at least 14 mol% of the aryloxy compound based on the total number of moles of hydroxyl groups contained in the linear polyol compound is introduced into the reaction system.
