Abstract
The Specification as open to inspection under Sect. 91 (3) (a) states that any alcohol or similar volatile liquid may be dehydrated by passing the vapours from, say, a dephlegmator through a succession of dehydrating-agents of increasing effectiveness, for example, through lime and then metallic calcium or calcium carbide. Preferably each dehydrating-agent is divided into two parts, the first of which is replaced when entirely used by the partly-used second portion, which is replaced by unused agents; and the vapours are heated prior to or during contact with the dehydrating-agent to prevent condensation thereon. This subject-matter does not appear in the Specification as accepted.ALSO:Absolute alcohol is obtained by passing the vapours from say a dephlegmator through a succession of dehydrating agents of increasing effectiveness, for example, through lime and then metallic calcium or calcium carbide. Preferably each dehydrating agent is divided into two parts, the first of which is replaced when entirely used by the partly-used second portion, which is replaced by unused agent; and the vapours are heated prior to or during contact with the dehydrating-agent to prevent condensation thereon. The alcohol with its absorbed acetylene, if carbide has been used, forms permanent homogeneous mixtures, suitable as motor spirit, with petrol, benzol, or other usual liquid hydrocarbon fuels as described in Specification 188,336. The alcohol may be used for any chemical or pharmaceutical preparation or for a beverage. Any alcohol or similar volatile liquid may be dehydrated similarly.
