General description

Biodegradation of 2-ethylhexyl nitrate (2-EHN) by Mycobacterium austroafricanum IFP 2173 has been studied[1]. Biodegradation of 2-EHN was studied in biphasic liquid cultures using an inert non-aqueous phase liquid such as 2,2,4,4,6,8,8-heptamethylnonane as solvent[2].

Application

2-Ethylhexyl nitrate (2-EHN) is a major fuel additive, has been used to increase the cetane number of diesel[1].

1–2 of 2 Questions  

  1. 「第4類: 引火性液体、第三石油類、危険等級III、非水溶性液体」とありますが、分子構造から見ると第5類に分類されると思われます。また、記憶違いかもしれませんが、以前は第5類だったと記憶しています。何か、法令の改正などにより危険物の分類が変更されたのでしょうか。

    1 answer

    1. 2-Ethylhexyl nitrate has a flash point of 76.1°C (169°F). It is has a GHS (Globally Harmonized System) Flammability rating of 4, the least hazardous. While 2-Ethylhexyl nitrate is combustible, it is not as hazardous as, for example, Butane which has a GHS Flammability rating of 1; flammability is rated on a scale from 1-4 based on the flash point.
