Abstract

511,247. Hydrating olefines USINES DE MELLE. Nov. 14; 1938, No. 33096. Convention date, Nov. 17, 1937. Drawings to Specification. [Class 2 (iii)] Olefines are hydrated directly to alcohols by passing the gaseous olefine, or gas containing olefine, through a battery of vessels through which passes in counter current to the gas a warm acid hydrating solution, the concentration of which is below that giving rise to secondary reactions, and the gas being emulsified in the acid in each vessel, preferably by centrifugal means. The hydrating solution containing the alcohol is passed from the last vessel to a tower where a hot inert gas or superheated -steam is blown through it and the gas leaving the tower is cooled to condense the alcohol, whiles the hydrating solution is made up to its initial strength and returned to the process. The vessels may be separate closed vessels connected by gas and liquid, pipes; or compartments in the same closed tank connected by gas pipes and overflows for the liquid. Examples are given of the production of ethyl alcohol from a mixture of ethylene and ethane, and isopropyl alcohol from a mixture of propylene and propane, using a pressure, slightly above atmospheric. Several groups of tanks may be used coupled in various ways. The hydrating solution may be sulphuric acid of 50-80 per cent., containing sulphates or bisulphates in solution and may b.e modified by adding sulphonic acids such as benzene sulphonic acid, as well as certain catalysts such as salts of silver, copper or mercury.
