General Description
Tan-colored pellets or an off-white solid. Slight odor.
Reactivity Profile
4,4'-METHYLENEBIS(2-CHLOROANILINE)(101-14-4) 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.
Air & Water Reactions
Insoluble in water.
Hazard
Toxic. A confirmed carcinogen, absorbedby skin. Causes bladder cancer and methe-moglobinemia.
Fire Hazard
Flash point data for this chemical are not available. 4,4'-METHYLENEBIS(2-CHLOROANILINE) is probably combustible.
Chemical Properties
off-white powder
Uses
Curing agent for polyurethanes and
epoxy resins
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.
Definition
ChEBI: A chloroaniline that consists of two 2-chloroaniline units joined by a methylene bridge.
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.
Health Hazard
4,4￠-Methylene bis(2-chloroaniline),
or MOCA, is carcinogenic in experimental
animals.
Flammability and Explosibility
Nonflammable
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.
