Odor:Odorless
Henrys Law Constant:Henry's Law constant = 8.1X10-9 atm-cu m/mol at 25 °C and pH 7
Dissociation Constants:pKa = 5.62 at 20 °C
Experimental Properties:Decomposes @ 260 °C|Forms water-soluble alkali-metal and amine salts, but, in hard water, the calcium salt is precipitated.|Hydroxyl radical reaction rate constant 1.3X10-11 cu cm/molec-sec at 25 °C /Estimated/
Air and Water Reactions:Insoluble in water.
Reactive Group:Amides and Imides
Reactivity Profile:MALEIC HYDRAZIDE can be decomposed by oxidizing agents. It can also be decomposed by strong acids. It forms water-soluble alkali-metal and amine salts. It is slightly acidic and may be titrated as a monobasic acid. Mild oxidation produces a compound which reacts instantly with dienes at -107° F to form crystalline derivatives. This chemical is slightly corrosive to iron and zinc. It is incompatible with pesticides that are highly alkaline in reaction. In the presence of heavy metal and iron, zinc, calcium and magnesium ions, sparingly-soluble salts are formed. (NTP, 1992)
Heat of Combustion:-8,200 BTU/LB= -4,500 CAL/G= -190X10+5 J/KG (EST)
Corrosivity:Liquid formulated products are corrosive to brass nozzles if sprayed undiluted.
