| | 1,3-Bis(aminomethyl)benzene Usage And Synthesis |
| Chemical Properties | m-Xylene-α,α0-diamine is a colorless liquid. | | Chemical Properties | CLEAR SLIGHTLY YELLOW LIQUID | | Uses | m-Xylylenediamine can be used:
- As a monomer for the synthesis of poly(vinylogous urethane) vitrimers.
- As a starting material for the synthesis of carbamate-protected multisubstituted bis-guanidine.
- For the synthesis of polyamides by catalytic dehydrogenation with diols.
| | Uses | Manufacture of polyamide fibers and resins, as
a curing agent. | | General Description | Colorless liquid with an amine smell. Mp: 14.1°C; bp: 273°C . Water soluble. | | Reactivity Profile | 1,3-Bis(aminomethyl)benzene is combustible (Flash point 139°C). Incompatible with acids, acid chlorides, acid anhydrides. | | Hazard | Moderately toxic by skin contact and ingestion.
Mildly toxic by inhalation. A severe skin, eye,
and gastrointestinal irritant. | | Safety Profile | Moderately toxic by
skin contact and ingestion. Mildly toxic by
inhalation. A severe skin and eye irritant.
When heated to decomposition it emits
toxic fumes of NOx. Used to make
polyamide fibers and resins and as a curing
agent. | | Potential Exposure | m-Xylene-α,α0-diamine is a source of
m-xylene di-isocyanate and used as an intermediate in the
manufacture of epoxy and polyamide resins. | | Shipping | UN 2735A mines, liquid, corrosive, n.o.s, or
