METHOD FOR PRODUCING CARBONATES

摘要

In an embodiment, a method of producing a carbonate comprises reacting carbon monoxide and chlorine in a phosgene reactor in the presence of a catalyst to produce a first product comprising phosgene; wherein carbon tetrachloride is present in the first product in an amount of 0 to 10 ppm by volume based on the total volume of phosgene; and reacting a monohydroxy compound with the phosgene to produce the carbonate; wherein the phosgene reactor comprises a tube, a shell, and a space located between the tube and the shell; wherein the tube comprises one or more of a mini-tube section and a second tube section; a first concentric tube concentrically located in the shell; a twisted tube; an internal scaffold; and an external scaffold.

1. A method of producing a carbonate, comprising:
reacting carbon monoxide and chlorine in a phosgene reactor in the presence of a catalyst to produce a first product comprising phosgene; wherein carbon tetrachloride is present in the first product in an amount of 0 to 10 ppm by volume, based on the total volume of phosgene; wherein the phosgene reactor is capable of producing greater than or equal to 2,000 kilograms of the first product per hour; wherein the phosgene reactor comprises a tube, a shell, and a space located between the tube and the shell; and wherein the catalyst is disposed in the tube and a cooling medium is located in the space, or the catalyst is disposed in the space and a cooling medium is located in the tube; wherein the tube comprises one or more of a mini-tube section and a second tube section; a first concentric tube concentrically located in the shell; a twisted tube; an internal scaffold; and an external scaffold; and reacting a monohydroxy compound with the phosgene to produce the carbonate.
