Toxicological Profile for 4,4’-methylenebis(2-chloroaniline) Mboca

Donor–Acceptor-Based Poly(toluidine-co-chloroaniline)s: Synthesis and Characterization

A series of poly(o-/m-toluidine-co-o-/m-chloroaniline) copolymers of different compositions were synthesized by an emulsion method with ammonium persulfate as the oxidant. The conductivity of the copolymers was two to five orders of magnitude higher than that of the homopolymers poly(o-toluidine) and poly(m-chloroaniline). Among the copolymers, the copolymer of o-toluidine and m-chloroaniline e...

Absorption of 4,4'-methylenebis [2-chloroaniline] by human skin.

A system was developed to measure percutaneous absorption of water-insoluble environmental agents into human skin. Percutaneous absorption of 4,4'-[14C]methylenebis [2-chloroaniline] (MBOCA) was measured during dry contact exposure of MBOCA with organ cultures of neonatal foreskin. Time-dependent exposures, autoradiographs, and thin-layer chromatography indicated that MBOCA was rapidly and prog...

Artificial selection of microbial ecosystems for 3-chloroaniline biodegradation.

We present a method for selecting entire microbial ecosystems for bioremediation and other practical purposes. A population of ecosystems is established in the laboratory, each ecosystem is measured for a desired property (in our case, degradation of the environmental pollutant 3-chloroaniline), and the best ecosystems are used as 'parents' to inoculate a new generation of 'offspring' ecosystem...

Photo-induced decomposition of 2-chloroaniline in aqueous solution.

A study was performed on the oxidizing degradation of 2-chloroaniline (used as a model pollutant in water) by photolysis (lambda = 254 nm). The change of spectrum and substrate concentration of treated solutions was measured spectrophotometrically as well as by HPLC. The yields of the degradation products (chloride ions, ammonium ions, formaldehyde, etc.) were studied as a function of UV-dose. ...
