PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-YELLOW VISCOUS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Decomposes on burning. This produces toxic and irritating fumes (phthalic anhydride - see ICSC 0315). Reacts with strong oxidants.
