Abstract:
A diaryl carbonate containing a compound of the following formula (I) in an amount of less than 1,000 ppm by mass, and a method for producing the same: wherein R 1  represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an aryl group, or an aryloxy group.

Claim (Index 3):
The method according to  claim 2 , wherein the fourth step comprises a distillation step of, using a distillation column, obtaining the diaryl carbonate containing the compound of the formula (I) in an amount of less than 1,000 ppm by mass from the top of the column and obtaining a mixture having concentrated the compound of the formula (I) from the bottom of the column, wherein the distillation step is conducted under the following conditions (a) and (b):\n (a) that the pressure at the top of the distillation column is 0.01 to 10 kPa, and (b) that the reflux ratio is 2 to 20.
