Diphenyl carbonate(DPC) as an important product was used for synthesizing polycarbonate instead of phosgene.To detect the reaction process and products,a gas chromatographic method for analyzing the(related) six compounds(methanol,DMC,anisole,MPC,phenol,DPC) during the transesterification of phenol with dimethyl carbonate(DMC) was first proposed and described.All the compounds mentioned above were well separated through a FFAP chromatographic capillary column.A good linear relationship between the(injection) amount versus peak area was observed with the correlation coefficients of 0.996 3,0.994 6,(0.996 9),0.998 1,0.977,0.996 1,and the detection limits of six related compounds were founded to be 0.114,0.171,0.041 0,0.080 4,0.051 9,0.075 8 g/L respectively.
