Containers of dibutyl ether, which have been opened and are more than 1 year old, may contain hazardous quantities of peroxides. Especially if they have screw caps, containers should not be opened, and should be disposed of by the appropriate authorities. When the container can be opened safely, check for peroxides as follows Wear butyl rubber gloves, laboratory coat, and eye protection. Work in the fume hood. Dissolve 100 mg of potassium iodide in 1 mL of glacial acetic acid. Add to 1 mL of the dibutyl ether. A pale yellow color indicates a low concentration (0.001-0.005%) and a bright yellow or brown color a high concentration (above 0.01% and hazardous) of peroxide in the sample.9... 

The mato feature of a contiguous process is that the final expl product does not remain in the app for a prolonged period of rime and the quantity accumulated at any period of time is much smaller than that in the batch process. The large quantity of expl material accumulated in a batch process, especially at the end of exothermic nitration,presents a serious safety hazard which is more or less absent in current continuous processes The continuous method of nitration is particularly useful when the rate of nitration is rapid (such as in case of manufg NG, NGc, or PETN) and an overheating and expln might take place with the batch process. Nitration of cellulose, on the other hand, does not proceed very rapidly (unless mixed acid contains phosphoric or glacial... 

CHAPTER 7 THE PREPARATION OF CYCLIC NITRAMINES Hazards Use great care when handling 99% nitric acid produces poisonous reddish-brown fumes of nitrogen oxides use maximum ventilation. Wear gloves when handling acetic anhydride, and glacial acetic acid both of which can produce skin irritation. Do not allow the reaction mixture temperature to rise above 50 Celsius. 

Hazards Wear gloves when handling glacial acetic acid, which can cause mild skin bums and irritation. Glacial acetic acid is flammable, so extinguish all flames before using. 

Hazards Wear gloves when handling glacial acetic acid. Glacial acetic acid can cause skin bums. 

Hazards Wear gloves when handling glacial acetic acid although glacial acetic acid is considered a weak acid, it may cause skin irritation on prolonged exposure. Lead nitrate may be a carcinogen, so do not handle with bare hands. 

Hazards Use care when handling glacial acetic add, and acetic anhydride, both of which are corrosive. 

N 1.3898. Miscible with eth, benz, chlf, glacial AcOH petr eth. Decompd violently by w or ale. Extremely irritating to the eyes. Can be prepd from glacial AcOH and phosphorus trichloride (see also Ref 6) or by other methods listed in Ref 1. Used as an acetyl ating agent and for the detn of w in organic liquids. Its toxicity, fire and explosion hazards are discussed in Refs 4 5... 

K Hazardous compounds acetic acid, glacial acetonitrile phenylisothiocyanate and triethylamine. With all these compounds the use of hood, goggles and protective gloves is recommended. 

Derivation By heating glacial acetic acid and phosphorus pentasulfide, with subsequent distillation. Hazard Toxic by ingestion and inhalation.

Glacial acetic acid is corrosive it can cause burns on the skin and on mucous membranes in the nose and mouth. Its vapors are also hazardous. Dispense it in the hood and use personal protective equipment. Avoid contact with skin, eyes, and clothing. Sodium hypochlorite emits chlorine gas, which is a respiratory and eye irritant. Dispense it in a fume hood.
