An organic chemistry laboratory should be equipped with a carbon dioxide or dry chemical (monoammonium phosphate) /- extinguisher (see Fig. 3). To use this type of extinguisher, lift it from its support, pull the ring to break the seal, raise the horn, aim it at the base of the fire, and squeeze the handle. Do not hold onto the horn because it will become extremely cold. Do not replace the extinguisher report the incident so the extinguisher can be refilled. 

The preparation of imides was reviewed recently and many methods are recommended. - Under somewhat drastic conditions ( > 200 °C) dicarboxylic acids react with ammonia, or compounds which are able to produce ammonia like urea, thiourea, formamide, sulfamic acid, ammonium carbonate and others to form cyclic imides (equation 52). Monoammonium salts of dicarboxylic acids give imides under pyrolytic conditions when distilled under reduced pressure. ...

CARBONIC ACID, MONOAMMONIUM SALT (1066-33-7) CHjOj HjN NH4HCO3 Noncomustible solid (Fire Rating 1). Violent reaction with strong acids, forming carbon dioxide. Reacts with strong bases, forming ammonia. In temperatures above 140°F/49°C, ammonia and carbon dioxide fumes are formed. Reacts with fluorine, magnesium, sodium hypochlorite. 

Conversion of Phenols to Amines. Aniline and some diphenylamine are formed when phenol and NHs solution are heated under pressure in the presence of FeCh, Al(OH)s, or Fe(OH)j. When NH and phenol or ortho-or para-cresols are reacted in the vapor phase over an AljO catalyst, yields of up to 88 per cent of the corresponding amines are obtained. However, these amines are customarily obtained by reducing the parent nitro compound, except in cases where it is difficult to obtain the required nitro isomer. For example, it is considered that the amination of symr xylenol is the best method of preparing sym-xylidine (l-amino-3,5-di-methylbenzene). When sym-xylenol is heated under pressure to 320 C with ammonium chloride, about equal amounts of sj/m-xylidine and sym-dixylylamine (5-imino-bis-l,3-dimethylbenzene) are formed. The ortho-and para-nitrophenols and nitrocresols can be aminat more readily. 2-Nitro-p-cresol [OH(l), N02(2), CHj(4)] and o-nitrophenol have been aminated in aqueous ammonia containing ammonium salts of weak acids to inhibit decomposition. Phosphoric, boric, carbonic, and formic acids were used. In one case it is claimed that 55-65 per cent yields of 2-nitro-p-toluidine (MNPT of commerce) were obtained when 2-nitro-p-cresol, 28 per cent aqueous NHj, and monoammonium phosphate, 1 11.5 0.2 molar ratio, were heated under pressure for 10 hr at 140-150°C and then 5 hr at about 160 C. Earlier workers, employing somewhat similar conditions, claimed excellent yields of MNPT when 1 mole of ammonium formate was used per mole of 2-nitro-p-cresol. ...
