Title:
METHOD FOR CONTINUOUSLY PRODUCING KETOMALONIC ACID COMPOUND USING FLOW REACTOR
Document Type and Number:
WIPO Patent Application WO/2015/122361
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for continuously producing a ketomalonic acid compound such as a ketomalonic acid diester or a hydrate thereof, which is an industrially useful compound, on an industrial scale and in a safe and steady manner.
The present invention relates to: a method in which a malonic acid diester, a carboxylic acid compound and a chlorous acid compound are used as raw material compounds, and these raw material compounds are mixed together to prepare a mixture and the mixture is supplied to a flow reactor continuously, thereby continuously producing a corresponding ketomalonic acid diester or a hydrate thereof; and a continuous production apparatus for performing the method.
