On diesel cetane number improvers and the development of mixed acids in China

Thread Content

In China, isooctyl nitrate is a relatively mature cetane number improver. However, after contacting other manufacturers that use it, I discovered a problem: we have to use a larger amount of this improver than others do. . . More than others. . Many. I just can’t sit still thinking about all that cash. After doing some research, I found that there are acid mixtures available as modifiers; these involve adding certain other acids along with isooctyl nitrate, and diphenylamine is used as a stabilizer. The improvement effect achieved is better than that of using single esters, and the key advantage is that the cost is lower – overall costs can be reduced significantly. I would like to ask the experts here: do you have any information on this topic? The original text states that \"a mixture of 50% 2-ethoxyethyl nitrate and 50% isooctyl nitrate exhibits a significant synergistic effect in improving the properties of diesel CN; a mixture of 99% ethanolic nitrate and 1% diphenylamine is a relatively safe CN improvement agent with low costs.\" Additionally, there were experiments conducted 10 years ago to synthesize ethylene glycol dinitrate, with an yield of 80%. I would like to ask whether there are any factories in China that produce such CN improvement agents What level has research on mixed acids reached at present? From what I understand, the current bottleneck in such research is stability; I’m not sure if this is correct. I seek guidance from experts!
