Abstract: A method is proposed for leakage monitoring in a tube bundle reactor (2) having a bundle of contact tubes (2) vertically arranged parallel to one another, through which a fluid reaction mixture is delivered, and through whose space (3) surrounding the contact tubes a liquid heat exchanger is delivered, and having one or more vent holes (4) for the liquid heat exchanger in the upper region of the tube bundle reactor (1), which connect the tube bundle reactor (1) to one or more equilibrating vessels (5, 6, 7) for the liquid heat exchanger, wherein at least one of the equilibrating vessels (5, 6, 7) for the liquid heat exchanger has a connecting line (8) for supplying the gas phase above the liquid level therein to an analysis device (9), which determines the composition of the supplied gas phase.
