Chemical Properties
Yellow liquid (2,4and 2,5-), or crystalline needles (3,4-).
Soluble in alcohol and ether; insoluble in water.
Uses
Organic synthesis, gelatinizing accelerators for
pyroxylin.
Definition
There are three isomers (2,4-; 3,4-; and 2,5-).
General Description
Yellow crystalline solids or liquids. Insoluble in water and combustible. Toxic by inhalation and skin absorption. Produces toxic oxides of nitrogen during combustion.
Air & Water Reactions
Flammable. Insoluble in water.
Reactivity Profile
Aromatic nitro compounds, such as NITROXYLOL, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Hazard
Toxic by ingestion, inhalation, and skin
absorption.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
A poison. Moderately
toxic by ingestion. When heated to
decomposition it emits toxic fumes of NOx.
