Nitrogen-free cetane number improver

This post was last edited by liuquan1100 on 2017-10-10 at 14:29. The cetane number improver I produced (nitro-free type) has shown varying results in refineries: in some cases, adding 200 ppm only resulted in an increase of 0.7 units, while in other cases, adding 1‰ led to an increase of 12 units. Is it related to the cetane number of basic diesel, or is it related to the boiling range and composition? It was originally used for producing isooctyl nitrate, but now it is used to produce products that do not contain isooctyl nitrate. Experienced friends, I would appreciate your advice regarding the sensitivity of cetane number improvers that are free of nitrate. Those with experience are also welcome to share their insights!
What is a nitrate-free cetane improver? Isooctyl nitrate is sensitive; in diesel with a high aromatic content, the increase in cetane number after adding the additive is minimal.
Cetane improvers that do not contain isooctyl nitrate or other nitro compounds as active ingredients show significant differences in their effectiveness when used with different diesel additives
