Abstract
525,184. Phosgene-acetylene condensation products. ARMOUR & CO. Feb. 17, 1939, No. 5386. Convention date, Feb. 24, 1938. [Class 2 (iii)] Liquid and solid condensation products are obtained by reacting phosgene with acetylene or an acetylenic hydrocarbon such as vinyl acetylene, ethyl acetylene and diacetylene in the absence of oxygen and with or without the presence of a catalyst such as iron or copper. In examples (1) liquid phosgene is treated in a cooled vessel at -5‹ C. with acetylene for 10 hours, the temperature rising to 20‹ C. ; the product is.a liquid which if heated to 100‹ C. in an autoclave yields a plastic solid which can be incorporated with fillers and moulded under pressure ; (2) phosgene and acetylene are heated in an autoclave at 100‹ C. for 10 hours the product being a fusible soluble solid. Polyhydroxy compounds may be made by saponification of the reaction products with caustic alkali under pressure, and these can be hydrogenated to give products useful as synthetic waxes. The Specification as open to inspection under Sect. 91, includes the use of metal acetylides instead of acetylene. This subject-matter does not appear in the Specification as accepted.
