Abstract

532,104. Olefine ozonides ; polystyrene. STANDARD TELEPHONES & CABLES, Ltd., and WARNER, A. J. May 12, 1939, No. 14233. [Class 2 (iii)] Ozonides of amylene and higher olefines are prepared by passing ozonized oxygen into the olefine at a temperature of -20‹ to -30<SP>0</SP>C. In the case of viscous olefines, a solvent is employed which is subsequently evaporated away. According to the examples, (1) ciiisobutylene, a mixture of 2:4:4-trimethyl-1-pentene and 2:4:4-trimethyl-2-pentene, prepared by dehydrating tertiary butyl alcohol with concentrated sulphuric acid, is placed in a vessel which is surrounded with solid carbon dioxide and ozonized oxygen is passed through a sintered glass plate immersed in the liquid olefine; when the liquid becomes viscous, the temperature is allowed to rise to -5‹C. and the ozonolysis carried to completion; (2) diamylene, which is a by-product of the chlorination of mixed pentanes and consists of 3:5:5-trimethylheptene-2 and 3:4:5:5-tetramethylhexene-2, is dissolved in dry hexane and ozonized oxygen is passed through the solution in a vessel surrounded with solid carbon dioxide ; the hexane is evaporated from the product by means of a vacuum pump ; amylene ozonide may be prepared in a similar manner. A mixture of styrene with any of the ozonides in the proportions used for accelerating its polymerization is stable for some days at a temperature of 0‹-5‹C.
