Organic Halogen Containing Materials

Thermal processes are typically used for highly toxic waste or highly concentrated organic wastes. If the waste contains PCB, dioxins, or other toxic substances, incineration should be chosen in order to assure destruction. If the wastes contain greater than 1000 parts per million of halogens (chlorinated materials), it would probably be desirable to select incineration of these wastes, after consideration of other options. In any case, a material may be incinerated or used as a fuel if the heat content is greater than 8500 BTUs per pound or, if between 2500 and 8500, it may be incinerated with auxiliary fuel. The waste components of concern are halogens, alkali metals and heavy metals. 

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. 

Reactions of di-halogens (I2, Br2) and inter-halogens (IBr, IC1) with organic molecules containing Group 16-donor atoms (LE L = organic framework, E = S, Se, Te) have been the subject of renewed interest in the past few years both for their intrinsic interest and for their implications in different fields of research which span from synthetic to biological, material, and industrial chemistry.1 11...

When an organic compound contains both a hydroxy group and a halogen atom on adjacent carbon atoms, an intramolecular version of this reaction forms an epoxide. The starting material for this two-step sequence, a halohydrin, is prepared from an alkene, as we will leam in Chapter 10. 

Cleaning Up Wash material from the apparatus with a minimum quantity of acetone which, except for the chloro compound, can be placed in the organic solvents container. The 1,4-dichlorobenzene solution must be placed in the halogenated organic waste container. 

Cleaning Up Since all of the test solutions contain halogenated material, all test solutions and washes as well as unused starting materials should be placed in the halogenated organic waste container.
