Amines hazard

Cleaning Up The residues from the distillation of 1,2-phenylenediamine and the solvent from the reaction should all be placed in the aromatic amines hazardous waste container since the diamine may be a carcinogen. 

Cleaning Up The filtrate from the reaction, although highly colored, contains little dye, but is very soluble in water. It can be diluted with a large quantity of water and flushed down the drain or, with the volume kept as small as possible, it can be placed in the aromatic amines hazardous waste container or it can be reduced with tin(II) chloride (see Experiment 4). The crystallization filtrate should go into the organic solvents container. 

Cleaning Up Dilute the reaction mixture with water, neutralize with sodium carlxinate, and remove the solids by vacuum filtration. The solids go in the aromatic amines hazardous waste container and the filtrate can be flushed down the drain. 

Cleaning Up Add household bleach (5.25% sodium hypochlorite solution) to the dye bath to oxidize it to the starting material. The mixture can be diluted with water and flushed down the drain or the small amount of solid removed by filtration and placed in the aromatic amines hazardous waste container.
