| abstract | 126,039. Compagnie des Produits Chimiques d'Alais et de la Camargue. Nov. 7, 1916. Addition tn 101,973, Benzene monosulphonic acid.-In the production of benzene monosulphonic acid as described in the parent Specification, the benzene vapours are passed through a superheater before entering the sulphonater. Using the apparatus shown in Fig. 1, the benzene vapours from boiler A pass through a superheater B and then to a sulphonater C; the benzene vapour and steam passing off are condensed in the coil E and are separated in the decanter F; a tower G containing quicklime, calcium chloride, &c. dries the benzene which then returns to the boiler; fresh benzene is added as required from the vessel H. Fig. 2 shows apparatus for carrying out the process in a continuous manner; the sulphonater C is constantly supplied with sulphuric acid by pipe M from vessel D and the sulphonated product flows away by the pipe N. Several continuous treatment apparatus may be arranged in series with a common benzene boiler, the first sulphonater only being fed with sulphuric acid and delivering its sulphonated product to the next sulphonater and so on; this arrangement permits more complete utilization of the sulphuric acid. |
