The ethylhexyl nitrate is to boost the cetane levels of the poor quality North American diesel fuel a couple of cetane points. Adding more (doubling or tripling the dose of PS has ZERO effect on the cetane boost, since 1-2% EHN concentration or other aryl nitrate additives are only good for a couple of cetane units due to their free radical electron transfer mechanism becoming maxxed out at those concentrations). Plus the high levels of aromatic low cetane ring compounds in North American diesel fuels limits the benefits of cetane enhancers.

European diesel #2 has almost no aromatic ring compounds and is very sensitive to EHN boost due to all the paraffins, but North American diesel #2 is not that highly refined and here diesel #2 is more of a waste product of gasoline production than it is a primary distillate like it is in Europe with their straight cut distillation.

Aromatic hydrocarbons have little to no cetane value. Here in North America they comprise 25%-45% of the diesel #2 chemical composition. They are basically gasoline components and end up in our diesel fuel due to poor refining methodologies for middle distillates. The reverse is true in Europe, where diesel fuel is a primary fuel in refineries and it contains less than %5 aromatic ring compounds of low cetane value....

The esterified fatty acids in PS are to add some extra lubricity to keep the pump internals and the injectors from wearing too fast.

The white bottle also has a bactericide and algicide added to keep microorganisms growth limited. Also, a pour point depressant is added for winter use at lower temperatures to prevent the molucular lattice formation which results in waxing.

I have all the chemisty data at home on CD-ROM from the SAE.

If you want to get their proprietary formulation, join the Society of Automotive Engineers (SAE) and purchase their Diesel Fuel and Diesel Fuel Additive CD-ROMs containg the peer reviewed publications from the entire American petrochemical industry and all their suppliers.


Sound - the MSDS won't be much good to you unless you are an orgainc chemist, since you will not understand what it is or what it is for. But at least your guess is correct, there is more than one chemical in PS!

By the way, since PS contains diesel #2, it has a minimum of 500 different hydrocarbon chemicals in it! /forums/images/graemlins/wink.gif

From a previous post:

</font><font color="blue" class="small">( 98% of the inactive ingredients in PS is 100% Diesel #2.
The other 2% active ingredients are ethylhexylnitrate and some esterified fatty acids )</font>

From the current post:

</font><font color="blue" class="small">( The white bottle also has a bactericide and algicide ..... Also, a pour point depressant is added )</font>

</font><font color="blue" class="small">( But at least your guess is correct, there is more than one chemical in PS!
)</font>

Yes.. i thought so.. even after your previous post listed only diesel, and then 2 other chemicals.. the fatty acid, and the EHN....

</font><font color="blue" class="small">( Sound - the MSDS won't be much good to you unless you are an orgainc chemist, since you will not understand what it is or what it is for )</font>

Besides that being a condescending statement, ( you don't have to be an organic chemist to have an understanding of chemistry, I'm sure there are plenty of serious hobby chemists, and technician level people inthe chemical industry that are quite aware of what does what.. etc..) In any case...For the purpose that I requested it, I wouldn't have to know exactly what each chemical or proprietary compound did.. My purpose for requesting it was to see if there were more than 3 chemicals listed in it.. etc.

My organic chemistry is limited in scope to wastewater systems... BOD, and some corrosion factors on concrete and metal pipes, resistant construction materials like epoxy coated pipes and slury tranches..e tc..

Great information. Thank you.

I have a BS in chemistry, so while I know a bit of organic chemistry, I also know just how complex it gets and how little I know!

So, other than keeping stuff from growing, diesel stabilizer does nothing to keep fuel from oxidizing over time, and it does nothing to keep the lighter stuff from evaporating. My storage tank sits outside and can get quite warm in the sun. I get it filled about every 4 or 5 months. Hopefully the fuel doesn't deteriorate too much in that amount of time.

Does gasoline stabilizer do any good?

Companies often get away without putting all of the constituents of a product on the MSDS sheets, claiming it contains proprietary information. As long as they list the hazards, proper handling, etc. of the proprietary compounds they usually aren't forced to do it. I'd be curious to see what the PS MSDS says.

Steve, most cetane enhancers (aryl nitrates and peroxides) are in reality just free radical producers, so it is well advised NOT to add them to the fuel prior to its utiliztion in a diesel engine, due to the fact that they cause auto oxidation and polymerization on thier own accord.

Heat and sunlight are of course also major contributors to the breakdown of diesel fuels due to the elevated temps causing more rapid oxidation and degradation.

Gasoline stabilizer contains a free radical quencher to capture electrons and stabilize double bonds from being attacked by free radicals ( the free radical preferentially attack the stabilizer molecule instead due to their free energy differences).

Sound, I did not think that you could understand or intrepret the MSDS of a petrochemical hydrocarbon product, and I still do not think that you could without further education, but good luck trying! /forums/images/graemlins/wink.gif
