1,2-PROPANEDIOL DINITRATE

Chemical Properties

Propylene glycol dinitrate is an explosive. It is a colorless, high-boiling liquid (solid below -8℃) with a disagreeable odor.

Chemical Properties

Colorless liquid; unpleasant odor. Slightly soluble in water.

Uses

Torpedo propellant in Otto Fuel II.

Uses

In the torpedo propellant Otto fuel II

General Description

Colorless liquid with a disagreeable odor. Mp: -30°C. Density 1.37 g cm-3 at 20°C. Slightly soluble in water (7.97 g L-1 H2O at 24.85°C).

Reactivity Profile

1,2-PROPANEDIOL DINITRATE is explosive. Acts as a strong oxidizing agent. Heating may cause a violent combustion or explosion producing toxic fumes (nitrogen oxides). May also decompose explosively from shock, friction or from a build-up of electrostatic charge that sparks suddenly to ground. Can begin a vigorous reaction that culminates in an explosion if mixed with reducing agents including hydrides, sulfides, and nitrides and numerous ordinary combustible materials. Reacts violently with Al, BP, cyanides, esters, PN2H, P, NaCN, SnCl2, sodium hypophosphite, and thiocyanates. Reacts with acids and with alkalis, including ammonia and amines. Must be stored in a cool, ventilated place, away from acute fire hazards and easily oxidized materials.

Hazard

Toxic by inhalation and skin absorption. Headache and central nervous system impairment.

Health Hazard

Propylene glycol dinitrate (PGDN) is a vasodilator, and at extremely high concentrations it causes methemoglobin formation.

Safety Profile

Poison by ingestion and subcutaneous routes. Moderately toxic by intraperitoneal and intravenous routes. Human systemic effects by inhalation: conjunctiva irritation, headache. An eye irritant. When heated to decomposition it emits toxic fumes of NOx. See also NITRATES.

Potential Exposure

Propylene glycol dinitrate has been used as a torpedo propellant. The explosion potential is similar to ethylene glycol dinitrate.

Carcinogenicity

Negative results were reported in various mutagenic assays including the Ames Salmonella assay (with or without microsomal activation), sister chromatid exchange assay in mouse lymphoma cells, mouse bone marrow cytogenic analysis, and mouse dominant lethal assay.

Incompatibilities

Explosive. A strong oxidizer. Contact with ammonia compounds, amines, strong acids; reducing agents; combustible materials may result in fire and explo- sion. It is similar to ethylene glycol dinitrate in explosion potential. Propylene glycol dinitrate may explode if strongly shocked or heated. Propylene glycol dinitrate is explosive.

Reacts violently with al, bp, cyanides, esters, pn2h, p, nacn, sncl2, sodium hypophosphite, and thiocyanates. Reacts with acids and with alkalis, including ammonia and amines .

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
