Title:
PROCESS FOR PRODUCING AROMATIC CARBONATE
Document Type and Number:
WIPO Patent Application WO/2004/016577
Kind Code:
A1
Abstract:
A process for continuously producing an aromatic carbonate with high energy efficiency wherein no complex step is taken. In particular, a process for producing an alkylaryl carbonate and/or a diaryl carbonate, comprising reacting a dialkyl carbonate with an aromatic hydroxy compound in the presence of a catalyst, wherein with the use of a reactor of such a structure that two or more independent reaction zones are connected to each other in series, a liquid phase is sequentially flowed from a front reaction zone to a last reaction zone and wherein the heat of condensation of vapor generated in at least one reaction zone, without bringing the vapor in direct contact with the relevant reaction mixture liquid, is transferred to a supply liquid to the relevant reaction zone or pre-stage reaction zone so as to heat the same, thereby accomplishing transesterification reaction.
