MOCA 4,4'-Methylene bis(2 -chloroa niline) CAS 101 -14-4
Introduction:
In the production of MOCA, o-chlora niline is reacted with hydroamine and hydrochloric acid to form o-chlora niline salt salt, and then condensed into crude MOCA by adding formaldehyde, neutralizing and distilling excess o-chlora niline, washing and recrystallization with ethanol to form granular body for sale. MOCA can be dissolved in dimethyl sulfoxide, dimethyl formamide and other organic solvents, but also soluble in heated polyether polyols, used to adjust the formulation of polyurethane adhesives.
Universal vulcanizing agent for polyurethane rubber, also suitable for crosslinked epoxy resins.
