Washbenzin=Naphtha? YES! CONFIRMED!

Migrated topic.

Hi everyone!

This short topic is intended to highlight what washbenzin is, something about which we here in Europe have been baffled for quite some time now. Is it the same as what Americans refer to as naphtha? Can they be used interchangeably?

To find an answer I set out to determine what washbenzin really is. I was looking for some sort of an indication on its container, and something got my attention. The so-called CAS number. It is kind of like a registration number that every chemical is given, for easier identification, when names may be misleading or confusing.

The CAS number I found on my bottle of washbenzin is this: 64742-89-8. In order to find out what the number really refers to I searched for a CAS number database that I found here: ...
I simply typed in the above number, and here is the result I got: "Solvent naphtha (petroleum), light aliph"

BINGO!

Washbenzin really is naphtha! Should you be worried whether your non-polar solvent is naphtha or not, look for the CAS number on the bottle and look it up on the website provided above!

Thanks for Your attention, I hope You can put it to good use.

Best regards, Anoki Ashoora

This was discussed quite recently in this forum: Naphtha in the Netherlands?

You can use the forum search engine to dig up all kinds of gems from the vault of knowledge that the dmt-nexus has grown to be over the years.

Congrats for doing some effort to search something on the net, not everyone does. As pitubo says Nexians were sure no part of the wasbenzin mystery club ;)

That CAS 64742-89-8 is a cool one for sure.

Not all putative naphtha (or whatever) will have a CAS number though. They will - in Europe - almost certainly have an EINECS number which performs a similar function. This is also know as the EC number.

CAS 64741-66-8 = EINECS 265-068-8
CAS 64742-49-0 = EINECS 265-151-9
CAS 64742-89-8 = EINECS 265-192-2
(These all being various forms of light naphtha, low in aromatics.)
 
Thanks for the input guys. I might have been able to search for answers in previous topics, but I felt an urge to look it up myself. Especially because the thing we call "stain-benzin" here I wasn't sure if it was "washbenzin" at all, or anything similar. All these stupid names in Europe...:)
