Abstract

The wastes, obtd. as residue when distilling off toluene diisocynate from toluenediamine phosgenation reaction mixts. contain 12-30 wt.% residual toluene diisocyanate and 6-25 wt.% free isocyanate gps. and are solid at 25 degrees C. They are used as hot melt or cold adhesives, as adhesion promoters esp. for rubber and tyre cords, in sawdust moulding compsns. for jewellery, as binder for carbon black etc. and in soln. as protective paint for wood. The compsns. contain =95 wt.% TDI -waste and >=5 wt.% free toluene diisocyanate.
