Diethylene glycol dinitrate is a chemical compound from the group of nitric acid esters . It was first described in 1927 by William H. Rinkenbach .
Extraction and presentation
Diethyleneglycoldinitrate can as nitroglycerin by nitration of diethylene glycol with mixed acid are prepared batchwise or continuously.
properties
Diethylene glycol dinitrate is an oily, colorless to yellowish, explosive liquid. It decomposes when heated above 190 ° C.
use
Diethylene glycol dinitrate is used for the production of low-smoke, erosion-reducing “cold” powders. During World War II, it was a component of German gun powders along with cellulose nitrate , centralite and potassium sulfate . The explosive power is only about 2/3 that of glycerol trinitrate , it is also less sensitive to impact. It can be gelatinized with collodion wool.
safety instructions
Diethylene glycol dinitrate reacts by impact or friction, heating or other ignition sources with rapid decomposition with the formation of large quantities of gas. The compound is a methaemoglobin generator and is as toxic as nitroglycerin. Its vapors or absorption through the skin cause headaches.
Diethylene glycol dinitrate was included in the EU's ongoing action plan ( CoRAP ) in 2016 in accordance with Regulation (EC) No. 1907/2006 (REACH) as part of substance evaluation . The effects of the substance on human health and the environment are re-evaluated and, if necessary, follow-up measures are initiated. The reasons for the intake of diethylene glycol dinitrate were concerns about the high risk characterization ratio (RCR) and the dangers arising from a possible assignment to the group of PBT / vPvB substances, the possible dangers due to carcinogenic and reproductive properties and as a potential endocrine disruptor . The re-evaluation took place from 2016 and was carried out by Italy . A final report was then published.
