Sodium 1-oxides, reactions with

Thus, Mathis et al. [1, 2] investigated oxidation reactions with 4-nitroperbenzoic acid, sodium hypobromite, osmium tetroxide and ruthenium tetroxide. Hamann et al. [3] employed phosphorus oxychloride in pyridine for dehydration. However, this method is accompanied by the disadvantages that the volume applied is increased because reagent has been added and that water is sometimes produced in the reaction and has to be removed before the chromatographic separation.

OSHA PEL TWA 1 mg(Fe)/m3 ACGIH TLV TWA 1 mg(Fe)/m3 DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE Poison by ingestion and intravenous routes. Experimental reproductive effects. Corrosive. Probably an eye, skin, and mucous membrane irritant. Mutation data reported. Reacts with water to produce toxic and corrosive fumes. Catalyzes potentially explosive polymerization of ethylene oxide, chlorine + monomers (e.g., styrene). Forms shock-sensitive explosive mixtures with some metals (e.g., potassium, sodium). Violent reaction with allyl chloride. When heated to decomposition it emits highly toxic fumes of HCl. 

The bulk material may ignite or explode in storage. Traces of water may initiate the reaction. A rapid exothermic decomposition above 175°C releases oxygen and chlorine. Moderately explosive in its solid form when heated. Explosive reaction with acetic acid + potassium cyanide, amines, ammonium chloride, carbon or charcoal + heat, carbon tetrachloride + heat, N,N-dichloromethyl-amine + heat, ethanol, methanol, iron oxide, rust, 1-propanethiol, isobutanethiol, turpentine. Potentially explosive reaction with sodium hydrogen sulfate + starch + sodium carbonate. Reaction with acetylene or nitrogenous bases forms explosive products.

An alternative chlorination technique involves the use of sodium hypochlorite (NaOCl) as the oxidant. Reactions with sodium hypochlorite are similar to those of chlorine except that there is no caustic requirement for destruction of free cyanide in the oxidation stages. However, alkali is required to precipitate metal-cyanide complexes as hydroxides. A typical oxidation system using chlorine and caustic is shown in Fig. 2. 

There are mass transfer tasks in the G/L systems, which require special reactor designs. Such tasks include absorption processes, in which strongly diluted gases necessarily participate and the liquid phase consists of liquids which are inmiscible or contain an readily precipitating solid. Examples are oxidation reactions with an ozone-air (3 vol.-% O3) or an ozone-oxygen mixture (6 vol.-% O3), flue gas scrubbing of 6-8 vol.-% CO2 with waste caustic soda, whereupon sodium carbonate is formed and upon exceeding its solubUity precipitates out, etc.
