Title: Antimony trichloride
Post by: kooga on July 23, 2008, 12:37:09 PM

Hello all,

I'm trying to replicate an old formula for wood finishing which mentions the use of "butter of antimony" which is antimony trichloride SbCl3.
My question is would it be possible to use antimony chloride which has the same chemical formula and have the same results, as in darkening the wood?
It will be mixed with mainly linseed oil.
Also the measurements are given in fluid oz, how does one go about to converting powder into fluid oz measurement as in concentrate?
Sorry if this is the wrong forum and yes I'm very aware not to mix it with water to avoid HCL and how dangerous it is to handle and the risks involved with exposure to antimony.

Many thanks  :)

If the antimony chloride is SbCl3, then it is the same as Antimony Trichloride.  As far the fluid oz. goes, I'm not sure what to tell you.  The melting point is ~73°C, maybe they melted it first?

Is the fluid oz. for after the SbCl3 is dissolved in something?  Or does the recipe state:

____ fluid oz. SbCl3

Thanks mac

The recipe states 2 fluid oz SbCl3

Fluid ounces is actually a measure of volume, isn't it? Approx 35 fluid oz to the litre (here in the UK), so 2 fl. oz ~ 57 cc, which if you also have the density you can then get a mass from...?

Thanks sjb,

Yes it is volume
Density is 3,14 don't know if it's kg/m³ or g/cm³.
So that would make 1,79 gram then? (density X volume = mass)
Sorry if it is a simple thing, been years since I had chemistry/physics.

If it is loose (like kitchen salt) you can measure volume, no problem. If it is like butter - you can as well. It is just like a cup of sugar in the recipe.

If 2 floz is 57 mL and density is 3.14 (g/mL most likely) you need 57x3.14g.

Note: mL, cc, cm³ - it is all the same.

That would make more sense volume wise.

Thank you all  :)
