ABSTRACT OF THE DISCLOSURE A process is disclosed for the production of thio- tetronic acid, in which 4-chloro-4-chloromethyloxetan-2- one is reacted directly with hydrogen sulfide in the presence of an amine to produce thiotetronic acid. Alternatively, the reaction mixture is converted prior to isolation of the thiotetronic acid with ketene and the conversion product is converted with a mineral acid in order to obtain the thiotetronic acid.
