The best base oil - Alkylated Naphthalene

Рет қаралды 8,191

Most people tend to think that polyalphaolefins are the top of the tree when it comes to base oils. But PAOs are so non-polar that they often encounter issues with additive solvency and varnish deposition, which necessitates a co-basestock in finished lubricants.
Esters on the other hand, are so polar that they suffer from hydrolytic instability, are hygroscopic, and sometimes out-compete lubricant additives at metal surfaces.
Alkylated Napthalenes are the "third way" lubricant - the best of both worlds.

Just came across your channel today. Great stuff! I used to be involved manufacturing AN, Esters and PAO's for a large oil company during the glory days of group 4 and 5 usage in engine oils. From an operations point, pure naphthalene is very difficult to handle, especially in colder weather. And as it's a batch operation like esters (PAO is continuous) it's more expensive to make by a significant margin than PAO. You're correct that putting the alykl group on different points of the ring yields different properties. Reactionwise, the hardest part is to get the alkyl group to hitch itself consistently to the same spot on the rings. We had to develop a proprietary catalyst to accomplish this.

Great insight! With over 20 years around ANs, you identify probably the main reason why there are only two players in the market. It's hard to make them consistently and cost-effectively. Of the two players in the market, one had already developed its downstream range before they decided to sell ANs. So, their R&D had almost all been completed & the downstream products were generating cash. As a result of the downstream product range, they can sell a wide range of ANs. The other (with whom I suspect you worked) had the resources to develop the two grades most likely to have a broad range of applications. The barrier to entry by either route is very high.

What do you think about high viscosity AN’s such as AN having vis@40C of 300 cSt ? Its aniline point is 125. Do you think it can still be used as solubilizer? I have heard that this grade might worsen the shear stability if we combine with PAO to formulate a synthetic automotive gear oil like 75w-90. Thanks in advance for your comments :)

I think there could be problems with seals, especially Buna N. Steric hindrance could prevent the naphthenic from migrating into the rubber, but the R groups would still allow Buna N process oils, additives, etc. to migrate out. The seal would therefore shrink. This is why you never have a Pure Buna N formula. A non-oil resistant rubber is always in the formula so it can swell to compensate for the shrink of the Buna N which is oil resistant.

@trevorgauntlett-jx8ub 7 ай бұрын

?You're right, and it has probably been an achille's heel for some product developments. However, you also have to remember that one player makes ANs with branched alkyl chains, while the other uses predominantly straight chains. Success may be possible by using the nearest product from the other player and/or moving to a lower viscosity AN, which usually means less substitution, so less steric bulk. Or back out some AN and add a little ester. Not a simple task, I agree. But it's why formulators are skilled people.

Good ol' LE, Thrashes it out... Rings the bells... I would disagree at one aspect - An oil, mainly based on Ester or AN, would be specific, racing oil, application? They're expensive. Also, Don't want to change oil seals, too often, in real life... For practical use: PAO + AN as a polarized, hydro stable, additive "solvent" , would be nice? (eg: Mobil?) Cost effective "solution" = GIII, kinda uniform molecules, a bit polar? A bit less AN, with additives? :) Pl do a show, on how Esters or AN's swell seals & Explain the difference between seal swelling & pliability?

@LubricationExplained 2 жыл бұрын

As far as engine oils go, yes, you'll probably never see a pure AN engine oil mainly because of its low VI. The only times I've seen AN oils are in industrial applications where you don't need performance over a wide temperature range, because most equipment operates at constant temperature for 99% of its life. In the engine oil world, you're right, it's most likely going to show up as a co-base with a PAO.

@LubricationExplained 2 жыл бұрын

Generally no. As it's a pure synthetic base oil - i.e. synthesised from known feedstocks, sulphur levels are vanishingly small. Naphthenic base oils (which are refined from naphthenic crude oil) will contain sulphur levels similar to other Group I, II, and III mineral oils, but that's a different base oil technology entirely, despite similarities in the name and ring structures. As @MyTech points out though, there's likely to be sulphur in the antiwear additives. Both ZDDP and MoDTC contain sulphur, as examples.

Granted - it's not going to be the main base oil for automotive and mobile equipment. But a lot of industrial equipment spends 99.9% of operating time at a very narrow temperature window - for these applications VI isn't really all that important. Like I said in the video, all base oils have their place - I just used "best" in the title because I'm experimenting with how KZfaq treats titles in the algorithm.
