Halogenated organic solvents

According to EPA regulations, land disposal of halogenated organic solvents (such as trichloroethylene) is restricted (EPA 1987e). Before land disposal of trichloroethylene or trichloroethylene-containing materials is attempted, proper authorization must be obtained from federal, state, and local authorities. 

Due to the volatile nature of arsine, there is minimal extended risk except in an enclosed or confined space. Arsine vapor has a density greater than air and tends to collect in low places. It is soluble in water as well as aromatic and halogenated organic solvents.

Sb reacts with chlorine or bromine forming antimony chloride or bromide with iodine, the reaction occurs in boiling benzene or halogenated organic solvent to form antimony truodide, Sbls.

Waste containers Nonhazardous solid waste Organic solvents Halogenated organic solvents... 

Cleaning Up Combine all aqueous layers, neutralize with sodium carbonate, dilute with water, and flush down the drain. Any solutions containing dichloromethane should be placed in the halogenated organic solvents container. Allow the solvent to evaporate from the sodium sulfate in the hood and then place the drying agent in the nonhazardous solid waste container. 

Cleaning Up Place the filtrate in the halogenated organic solvents container. 

Cleaning Up Place the entire test solutions from parts 3(A), 3(B), 3(E), 3(F), and 3(G) in the halogenated organic solvents container. Dilute the solutions from tests 3(C) and 3(D) with water, place the organic layer in the organic solvents container and, after neutralization with sodium carbonate, flush the aqueous layer down the drain. 

Cleaning Up Since the filtrate from this reaction contains 1,2-dichlorobenzene, it should be placed in the halogenated organic solvents container. 

Cleaning Up The filtrate contains ethanol, iodobenzene, triglyme, and probably small amounts of the reactants and the product. Place the mixture in the halogenated organic solvents container. 

Cleaning Up Place dichloromethane solutions in the halogenated organic solvents container and organic solvents in the organic solvents container. The alumina should be placed in the alumina hazardous waste container. If it should be necessary to destroy 3-chloroperoxybenzoic acid, add it to an excess of an ice-cold solution of saturated sodium bisulfite in the hood. A peracid will give a positive starch/iodide test (blue-purple color).
