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.

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

Check Digit Verification of cas no
The CAS Registry Mumber 6423-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6423-43:
(6*6)+(5*4)+(4*2)+(3*3)+(2*4)+(1*3)=84
84 % 10 = 4
So 6423-43-4 is a valid CAS Registry Number.

Practical catalytic nitration directly with commercial nitric acid for the preparation of aliphatic nitroesters

To pursue a sustainable and efficient approach for aliphatic nitroester preparation from alcohol, europium-triflate-catalyzed nitration, which directly uses commercial nitric acid, has been successfully developed. Gram scalability with operational ease showed its practicability.
Separation of Diastereomeric and Enantiomeric Alkyl Nitrates - Systematic Approach to Chiral Discrimination on Cyclodextrin LIPODEX-D
Schneider, Manfred,Ballschmiter, Karlheinz
, p. 539 - 544 (2007/10/03)
High-resolution gas chromatographic separation of all diastereomeric monomethyl-substituted cyclohexyl nitrates is shown on a nonpolar methylpolysiloxane stationary phase, and the first application of this procedure to the environmental diastereomeric analysis of alkyl nitrates is presented.Two characteristic signals in the achiral analysis of atmospheric samples could be assigned to the smallest alkyl nitrate containing two asymmetric carbon atoms, 3-methyl-2-pentyl nitrate.Retention indices in the temperature-programmed separation based on the n-alkanes were determined.The homologous series of 1-alkyl nitrates were found to be useful as ECD-visible n-alkanes.Enantiomeric separation of alkyl nitrates was achieved on heptakis(3-O-acetyl,-2,6-di-O-pentyl)-β-cyclodextrin (LIPODEX-D).The influence of the nitrooxy group and the alkyl chain length on the chiral discrimination on LIPODEX-D is discussed for 25 chiral alkyl nitrates.The absolute configurations of some alkyl nitrates were assigned by asymmetric synthesis of enantiomerically pure references.The complexity of the alkyl nitrate mixtures present in air samoles does not allow a direct chiral separation as the alkyl nitrates partly coelute on the LIPODEX-D column.Column coupling of LIPODEX-D with a polar achiral stationary phase like polyalkylenglocol (PAG) was successfully applied to solve this problem, and the chiral alkyl nitrates present in a typical air sample were separated.A systematic nomenclature for alkyl nitrates is introduced to handle the steadily growing number of branched and long-chain nitrates detected in environmental analysis. - Keywords: analytical methods; alkyl nitrates; chiral resolution; cyclodextrins; gas chromatography
Process for the production of high energy materials
-
, (2008/06/13)
A process for the production of a high energy nitrate ester involves reacting, in an inert organic solvent, a heterocyclic compound, selected from oxiranes, oxetanes, N-substituted aziridines and N-substituted azetidines, with either N2 O4 or N2 O5, and when the compound is reacted with N2 O4, oxidizing the O- or N-nitrate substituents or substituent in the product to O- or N-nitrate substituent or substituents. The remaining ring carbon atoms on the heterocyclic compound may be substituted or unsubstituted. Preferred substituent groups for the C and/or N ring atoms on the compound include alkyl, cyanoalkyl, haloalkyl, nitroalkyl, and substituted aryl. Several novel nitrate ester are also provided, including nitrated derivatives of polybutadiene, in which between 1% and 25% of the carbon atoms in the polymer are substituted by vicinal nitrate ester (--ONO2) groups.
