There is Htde evidence of the direct formation of sodium carbide from the elements (29,30), but sodium and graphite form lamellar intercalation compounds (16,31—33). At 500—700°C, sodium and sodium carbonate produce the carbide, Na2C2 above 700°C, free carbon is also formed (34). Sodium reacts with carbon monoxide to give sodium carbide (34), and with acetylene to give sodium acetyHde, NaHC2, and sodium carbide (disodium acetyHde), Na2C2 (see Carbides) (8). [Pg.163]

Sodium acetylide [1066-26-8] M 48.0. It disproportionates at ca 180° to sodium carbide. It sometimes contains diluents, e.g. xylene, butyl ether or dioxane which can be removed by filtration followed by a vacuum at 65-60°/5mm. Alternatively the acetylide is purged with HC=CH at 100-125° to remove diluent. NaC2H adsorbs 2.2x, 2.0x and 1.6x its wt of xylene, butyl ether and dioxane respectively. Powdered NaCaH is yellow or yellow-gray in colour and is relatively stable. It can be heated to ca 300° in the absence of air. Although no... [Pg.464]

Sodium reacts with carbon monoxide at 250 to 340°C forming sodium carbonyl, (NaCO)e. At higher temperatures, sodium carbide Na2C2 is formed. With acetylene the products are sodium acetyhde, NaC CH and disodium... [Pg.849]
