628-96-6 Usage
Chemical Properties
Ethylene glycol dinitrate is a colorless to yellow,
oily, odorless liquid. An explosive ingredient (60%80%)
in dynamite along with nitroglycerine (40%20%). It may
be detonated by mechanical shock, heat, or spontaneous
chemical reaction
Uses
Different sources of media describe the Uses of 628-96-6 differently. You can refer to the following data:
1. Explosive for mining and fuel industries. Additive to dynamite. Detection of hidden bombs by analysis of ambient air for EGDN.
2. As an explosive usually mixed with
nitroglycerin (NG) in the manufacture of
dynamite
Definition
A freezing-point depressant for
nitroglycerine.
General Description
Colorless to yellow, oily odorless liquid with a sweetish taste. Mp: -22°C; bp: explodes at 114°C. Density: 1.49 g cm-3. Soluble in water (23.3 g/L H2O) at 25°C). Very soluble in ethanol and in ether. Used as an explosive ingredient in dynamite along with nitroglycerine. Toxic; can penetrate the skin.
Reactivity Profile
EGDN is explosive. Acts as a strong oxidizing agent. Heating to 114°C or above 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 (Sax and Lewis, 1987 p.664).
Hazard
Toxic by skin absorption.
Health Hazard
EGDN causes vasodilation and
cardiac effects.
Safety Profile
Can cause lowered
blood pressure leading to headache,
dizziness, and weakness. Used as an
explosive. When heated to decomposition it
emits toxic fumes of NOx. See also
NITRATES.
Potential Exposure
An explosive ingredient (60%80%)
in dynamite along with nitroglycerine (40%20%).
Although ethylene glycol dinitrate is an explosive in itself,
it is primarily used to lower the freezing/melting point of
nitroglycerin; together these compounds are the major constituents of commercial dynamite, cordite, and blastine gelatin. Occupational exposure generally involves a mixture of the two compounds. Ethylene glycol dinitrate is 160 times
more volatile than nitroglycerin.

Check Digit Verification of cas no
The CAS Registry Mumber 628-96-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 628-96:
(5*6)+(4*2)+(3*8)+(2*9)+(1*6)=86
86 % 10 = 6
So 628-96-6 is a valid CAS Registry Number.

Organic nitric acid esters have been prepared in 89-98% yield by the nitration of the corresponding alcohols and polyols with N2O5 in liquid CO2.
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
