本発明は、炭酸エステルの製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing a carbonate ester.
炭酸エステルはポリマーや医農薬製造原料及び溶剤とし

方法（特公昭５Ｂ−３３８５７など）が知られている。(Prior art) As a method for producing carbonic ester, there is a method of reacting alcohol with phosgene (Japanese Patent Publication No. 58-50977, Japanese Patent Publication No. 59-59).
-492, etc.), but this method requires the use of highly toxic phosgene, and chloride ions are mixed into the carbonate ester, which is difficult to remove. A method is known in which alcohol is reacted with carbon monoxide and oxygen in a liquid phase in the presence of a catalyst containing copper (Japanese Patent Publication No. 5B-33857, etc.).

などの問題点も抱えている。This method has the problem of corrosion of the reactor material due to halide compounds, and there are no industrial materials other than glass lining, and it also has problems such as slurrying of the catalyst and reduction in catalyst activity.

い。Reaction under gas phase conditions (US4625044, W08?-1
07601), corrosion of the reactor material due to the halogen in the catalyst still occurs, and expensive special metals such as Hastelloy C are required. Additionally, there is a problem that halogen may be mixed into the carbonate ester. Furthermore, halogen is reduced during the reaction, inevitably resulting in a decrease in catalyst activity.

The purpose of the present invention is to provide a new method for producing carbonate esters in a reaction system that does not require the following steps.

度の炭酸エステルを得ることが可能となった。(Effects of the Invention) A carbonic acid ester can be obtained in the presence of metal steel using alcohol, a carbon monoxide bag, and oxygen under mild conditions without corroding the reactor. Since there is no corrosion, it is possible to use inexpensive general-purpose materials such as 5Us-316L for the reactor. Furthermore, it has become possible to obtain highly pure carbonate ester without fear of contamination with impurities.
