Abstract
Compounds that are themselves effective cetane improvers in diesel fuel but are considered too explosion sensitive for safe handling can be rendered relatively nonsensitive by blending with nitric acid esters of bicyclic or tricyclic alcohols containing a four-membered or five-membered ring and the resulting blend is an effective cetane improver. An example is a 50-50 blend of 2-methyl-2-nitropropyl nitrate, a shock-sensitive compound, with 5,6-cyclopenteno-2-norbornyl nitrate to give a relatively insensitive, but very effective cetane improver.
