4,4'-DDE Usage And Synthesis
Chemical Propertieswhite crystalline powder
UsesMilitary product; chemical research. Degradation product of p,p′-DDT.
DefinitionChEBI: A chlorophenylethylene that is ethylene substituted by two 4-chlorophenyl groups at position 1 and two chlorine atoms at position 2.
General DescriptionWhite crystalline solid or white powder.
Air & Water ReactionsInsoluble in water.
Reactivity Profile4,4'-DDE is sensitive to exposure to light. 4,4'-DDE is incompatible with strong oxidizing agents and strong bases. Oxidation is catalyzed by UV radiation.
Health HazardA derivative of DDT; structurally and toxicproperties are similar to those of DDT;however, the acute effects are somewhatmilder; moderately toxic by ingestion; ateratogenic substance; adequate evidence ofcarcinogenicity in experimental animals
LD50 oral (rat): 880 mg/kg
LD50 oral (mouse): 700 mg/kg.
Fire HazardFlash point data for 4,4'-DDE are not available. 4,4'-DDE is probably combustible.
Safety ProfileSuspected carcinogen withexperimental carcinogenic and neoplastigenic data. Poisonby ingestion. Experimental reproductive effects. Mutationdata reported. An insecticide. When heated todecomposition it emits very toxic fumes of Cl-.
SourceAgricultural runoff degradation of p,p′-DDT (quoted, Verschueren, 1983).
Environmental FateBiological. In four successive 7-day incubation periods, p,p′-DDE (5 and 10 mg/L) was recalcitrant to degradation in a settled domestic wastewater inoculum (Tabak et al.,1981).
Photolytic. When an aqueous solution of p,p′-DDE (0.004uM) in natural water samples collected from California and Hawaii was irradiated (maximum λ= 240 nm) for 120 hours, 62% was photooxidized to p,p′-dichlorobenzophenone (Ross and Crosby, 1985).
When p,p′-DDE in water was irradiated at 313 nm, a quantum yield of 0.3 was achieved. A photolysis half-life of 0.9 days in summer and 6.1 days in winter by direct sunlight at 40° latitude was observed. Photolysis products included DDMU (yield 20%), o-chl
When p,p′-DDE in a methanol solvent was photolyzed at 260 nm, a dichloro-benzophenone, a dichlorobiphenyl, DDMU and 3,6-dichlorofluorenone (yield 10%) formed as the major products (Plimmer et al., 1970). Chemical/Physical. May degrade to bis(chlorophenyl)acetic acid (DDA) and hydrochloric acid in water (Verschueren, 1983) or oxidize to p,p′-dichlorobenzophenone using UV light as a catalyst (U.S. Department of Health and Human Services, 1989).
Purification MethodsCrystallise DDE from MeOH or EtOH and dry it in vacuo. The purity is checked by TLC. [G.tzi & Stammbach Helv Chim Acta 28 569 1946, Beilstein 5 H 639, 5 III1891.] POSSIBLE CARCINOGEN.
