FIELD: chemistry.
SUBSTANCE: invention relates to method of removing alkanol admixture from flow, containing organic carbonate and alkanol admixture, which includes contact of flow with catalyst for influence on reaction of alkanol admixture with organic carbonate, where organic carbonate is represented by di(C1-C5)alkylcarbonate; or di(C5-C7)arylcarbonate; or (C1-C5)alkyl(C5-C7)arylcarbonate; or cyclic (C1-C10)alkylenecarbonate or their mixture; and where alkanol admixture is represented by alkoxy alkanol.
EFFECT: invention relates to method of obtaining diarylcarbonate, which includes contact of flow which contains dialkylcarbonate and alkanol admixture, with catalyst for impact on reaction of alkanol admixture with dialkyl carbonate by said method, and after that, contact of aryl alcohol in presence of re-etherification catalyst with dialkylcarbonate-containing flow.
