Abstract: The invention relates to a method of performing a chemical reaction under elevated pressure. It is suggested that the method comprises the steps of pressurizing a first vessel (3) and a second vessel (5) with reactant-containing liquid and gas to a predetermined pressure, providing reaction conditions in one of the vessels (3, 5) such that the chemical reaction is effected and a product-containing liquid is obtained, withdrawing liquid from the respective vessel (3, 5) as reaction product when a predetermined amount of reaction product has formed, preferably after the chemical reaction in the respective vessel (3, 5) has concluded, and synchronously supplying reactant-containing liquid to the respective other vessel (3, 5), wherein the first and second vessels (3, 5) are in fluid communication by way of a gas communication passage (27). The invention also relates to an apparatus and use thereof for performing said chemical reaction.
