Chlorine-containing organic compounds

Chlorine makes up 50% or more of the weight of all the chlorinated hydrocarbons under consideration except methoxychlor, which contains 30%. Therefore, methods based on the determination of total chlorine appear appropriate. Such methods are not specific, however, and any other chlorine-containing organic compound will interfere.

Some chlorine-containing organic compounds are viscous, oily liquids which may be utilized as lubricants, either alone or admixed with petroleum oils. Typical materials of this type are chlorodiphenyls, chloronaphthalenes, and chlorinated paraffin wax 205). 

Among famous methods of BR chlorination by molecular chlorine or chlorine-containing organic compounds in solution, water dispersion and liquid melt [27,143,176,262, 266] chlorination of BR by molecular chlorine in solution is the most manufacturable method. Process consists of several power-consuming stages [27,176,177] ... 

Among the well-known methods of BR chlorination with molecular chlorine or chlorine-containing organic compounds, including in solution, water dispersion, and melt [8, 24, 25] the most processable is chlorination with molecular chlorine in solution. 

The success of DDT in 1940s and 1950s led to a development of aU kinds of chlorine-containing organic compounds for pesticides, herbicides, and disinfectants. Many of them were introduced as commercial products, and used widely. Some of those compounds are shown in Fig. 16.1 along with DDT. These seven compounds (except t ,p-DDT) are often labeled as dirty seven for their toxic effects.

Keyes and Marshall[325] found that CI2 adsorption on degassed activated carbon is exothermic. Its initial heat amounts to 31,9 kcal mol and drops to 24.6 kcal mol with increasing concentration of adsorbed chlorine. This corresponds to an energy of 44 kcal mol for the C-Cl adsorption bond (with a subsequent decrease to 41 kcal mol ), which is considerably lower than typical values of the C-Cl bond energy in chlorine-containing organic compounds 70 kcal mol [304]).
