It undergoes many condensation and addition reactions with carbonyl compds, active methylene compds, and activated olefins (Refs 10,43,... 

Chemical Reactions. TNMe is a strong acid and forms salts with metals and bases (see below). It readily reacts with formaldehyde to form trinitroethanol (Ref 16). it adds to activated double bonds, such as ft, J -un saturated carbonyl compds and vinyl ethers (Ref 19b). 

The principal organic reaction of ozone is its addition to the carbon-carbon double bond of an ethylenic compd. The resulting ozone-olefin addition compd is known as an ozonide. Decompn of the ozonide gives a mixt of oxygenated products containing carbonyl compds and acids. 

The primary ozone-olefin addition product splits into a molozonide zwitterion (3). The zwitterion (3) then stabilizes by splitting into a carbonyl compd (4) and another zwitterion (5). 

Now chemists at the Central Research Laboratories of Produits Chimiques Ugine Kuhlmann (PCUK) at Lyons, France, developed beginning in 1970, under the direction of Dr F. Weiss, a novel continuous process for manufg hydrazine. The process is based on the discovery that ammonia, hydrogen peroxide, and a carbonyl compd, such as methyl ethyl ketone, react in presence of an amide and catalytic quantities of a phosphate to form an azine intermediate. This intermediate hydrolyzes quantitatively to hydrazine and to carbonyl compd which is recycled. The yield is claimed to be better than 75%...
