Acetaldehyde flammability limits

Methyl vinyl ether is rapidly hydrolysed by contact with dilute acids to form acetaldehyde, which is more reactive and has wider flammability limits than the ether [1], Presence of base is essential during storage or distillation of the ether to prevent rapid acid-catalysed homopolymerisation, which is not prevented by antioxidants. Even mildly acidic solids (calcium chloride or some ceramics) will initiate exothermic polymerisation [2],... [Pg.437]

Acetaldehyde — Fire Hazards Flash Point (deg. F) -36 CC -59 OC Flammable Limits in Air (%) 4 - 60 Fire Extinguishing Agents Dry chemical, alcohol foam, carbon dioxide Fire... [Pg.279]

Table 4.10 hsts the flash points for a number of common solvents with flash points below or close to the normal operating temperature (about 38 F or 3.3 C) of a common refrigerator. Also given are the flammable limits in percent by volume in air for these same solvents. Most of these evaporate rapidly so that they quickly reach equihbrium concentrations in a small confined space. Some of the most dangerous are acetaldehyde, carbon disulfide, diethyl ether, and ethylene amine, which have broad explosion limits. [Pg.271]
