Abstract
An object is to provide a new method for producing an aromatic bis ether compound in an industrially stable manner and in high yield. As a solution, a method for producing an aromatic bis ether compound represented by formula (3), in which in a reaction between an aromatic dihydroxy compound (1) represented by formula (1) above and a halide (2) represented by formula (2) above, the amount of water in a reaction solution is 0.01 wt % or more and 1.5 wt % or less relative to the amount of the aromatic dihydroxy compound (1) in the reaction solution, is provided.
Claims1
A method for producing an aromatic bis ether compound represented by formula 3-3 below, wherein in a reaction, in the presence of a linear aliphatic ketone having 5 to 8 carbon atoms, between an aromatic dihydroxy compound 1 represented by formula 1-3 below and a halide 2 represented by formula 2 below, an amount of water in a reaction solution is 0.01 wt % or more and 1.5 wt % or less relative to an amount of the aromatic dihydroxy compound 1 in the reaction solution,
- wherein each R1 independently represents a linear alkyl group having 1 to 6 carbon atoms or a branched alkyl group having 3 to 6 carbon atoms, or a cyclic alkyl group having 5 or 6 carbon atoms, and each n independently represents an integer of 0 to 4,
- wherein Y represents a chlorine atom, and A represents a group represented by formula 2a below,
- wherein R4 is a linear alkyl group having 1 to 6 carbon atoms or a branched alkyl group having 3 to 6 carbon atoms, and * represents a bonding position,
- wherein R1 and n are as defined in formula 3, and A is as defined in formula 2.
