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 2):
A method for producing the diaryl carbonate according to  claim 1 , the method comprising:\n a first step of reacting urea with an alkyl alcohol to yield a first reaction mixture containing a dialkyl carbonate; a second step of reacting the dialkyl carbonate in the first reaction mixture with an aryl alcohol to yield a second reaction mixture containing an alkylaryl carbonate; a third step of subjecting the alkylaryl carbonate in the second reaction mixture to disproportionation to yield a third reaction mixture containing a diaryl carbonate; and a fourth step of purifying the third reaction mixture, wherein the third reaction mixture further contains the compound of the formula (I) in an amount of 1,000 ppm by mass or more.
