Abstract

14,342. Askenasy, P., and Mugdan, M. June 27. Hydrochloric acid; sulphuric acid.-According to a known reaction, a mixture of hydrochloric and sulphuric acids can be obtainei by passing chlorine and sulphurous acid into water. According to this process, these gases in the required proportions are led to the bottom of a tower down which water or dilute hydrochloric-acid solution is passed. Concentrated sulphuric acid escapes from the bottom of the tower, and hydrochloric-acid gas from the top. Sulphuretted hydrogen or hot pyritic gases may be added to the entering gases. To ensure that the gas feed is kept uniform, a part of the gaseous mixture enters continuously into fresh water, and any surplus of one or the other of the gases is tested by measuring with a suitable meter the potential imparted by the same to an indifferent electrode in comparison with an electrode of constant potential. The feed of one or other of the gases may be automatically regulated by combining a suitable relay with the testing-device. To obtain absolutely - pure hydrochloric acid, chlorine is added in excess, and the excess subsequently removed from the escaping gas by a reducing medium, such as ferrous chloride, sulphuretted hydrogen, &c.
