Claims
- 1. In a process for the preparation of di(aryloxy) compounds of the formula: ##STR5## wherein A is a lower alkylene group and each R.sub.1 to R.sub.5 may be the same or different and independently are selected from the group consisting of a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a carboxylic acid salt group, an acyl group, a cyano group, a cycloalkyl group, an aryl group and a nitro group and two adjacent groups of R.sub.1 to R.sub.5 when together from a divalent cyclic moiety, by a condensation reaction between a dihalogenated compound represented by the Formula
- X--A--Y (II)
- wherein X and Y each represent a halogen atom and A is as defined above; and a phenol represented by the Formula ##STR6## wherein R.sub.1 to R.sub.5 are as defined above; in the presence of a base in an aqueous, the improvement which comprises; carrying out said condensation reaction in a molar ratio of said dihalogenated compound: phenol: base of 1:1.5 to 3.0:1.5 to 3.0, and adding, the base gradually during the condensation the reaction; and maintaining the proportion of aqueous medium phase in the reaction mixture at 35% by weight or less based on the quantity of the oily phase present in the reaction mixture.
- 2. A process of claim 1 wherein an alkali metal hydroxide or an aqueous solution thereof is used as said base.
- 3. A process of claim 1 wherein said condensation reaction is carried out in the presence of an anionic surfactant.
