| | 4,4'-Methylene bis(2-chloroaniline) Usage And Synthesis |
| Chemical Properties | off-white powder | | Uses | MOCA is widely used in machinery, automobile, aircraft manufacturing, mining, industrial and sports facilities (such as plastic track and plastic floor) can be used for curing and waterproof coatings such as epoxy resin, which can be given to polyester and polyether elastomer most good physical and mechanical properties and the results. | | Uses | Curing agent for polyurethanes and
epoxy resins | | Production Methods | The production of MOCA in the United States has ceased
since 1979 and is now imported, mainly from Japan. More
than 1.9 million lb was imported in 1989. The compound is
currently used as a curing agent for isocyanate-containing
polymers and in the manufacture of polyurethane foams,
epoxy resins, gun mounts, jet engine turbine blades, radar
systems, and components in home appliances. It is also a
model compound for studying carcinogenesis. | | Definition | ChEBI: A chloroaniline that consists of two 2-chloroaniline units joined by a methylene bridge. | | General Description | Tan-colored pellets or an off-white solid. Slight odor. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 4,4'-Methylene bis(2-chloroaniline) is a weak base. Undergoes an exothermic and self-sustaining decomposition reaction when exposed to heat above 392°F, In a closed container, the pressure buildup can be rapid enough to cause an explosion. | | Hazard | Toxic. A confirmed carcinogen, absorbedby skin. Causes bladder cancer and methe-moglobinemia. | | Health Hazard | 4,4￠-Methylene bis(2-chloroaniline),
or MOCA, is carcinogenic in experimental
animals. | | Fire Hazard | Flash point data for 4,4'-Methylene bis(2-chloroaniline) are not available. 4,4'-Methylene bis(2-chloroaniline) is probably combustible. | | Flammability and Explosibility | Nonflammable | | Safety Profile | Confirmed carcinogen
with experimental carcinogenic and
tumorigenic data. Poison by ingestion and
intraperitoneal routes. Mutation data
reported. Flammable liquid. Reactive with
active metals such as sodium, potassium,
magnesium, or zinc. When heated to
decomposition it emits very toxic fumes of
Cland NOx. | | Carcinogenicity | 4,4′-Methylenebis(2-chloroaniline) is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. |
