Abstract

525,198. Diolefines. USINES DE MELLE. Feb. 15, 1939, No. 4971. Convention date, March 21, 1938. [Class 2 (iii)] Diolefines are made by heat-treatment of glycols or of olefine alcohols in the presence of volatile phosphorus compounds in the vapour phase. Suitable phosphorus compounds are the oxychloride, trichloride and pentachloride and phosphoric acid esters. They may be added to the alcohol or may be injected separately into the reaction space. In examples (1) butylene glycol at 300-350‹C. is sent into a vertical quartz or non-corrosive steel furnace containing at its upper part porcelain pellets to act as a vaporizer, and triethyl phosphate vapour is injected into the furnace ; (2) in a similar process phosphorus oxychloride is employed, and the furnace is filled with inert matter such as pumice or wood charcoal. A small proportion of unsaturated alcohols are produced as a bye-product and are returned to the process to be converted into diolefine. In a third example crotonyl alcohol to which phosphorus oxychloride has been added is employed. The product of these examples is butadiene but from higher glycols and olefine alcohols higher diolefines such as isoprene are obtained. Specification 511,534 is referred to. The Specification as open to inspection under Sect. 91, includes the use of any volatile catalyst. This subject-matter does not appear in the Specification as accepted.
