Phosphoric Acid anhydrous and others


Self explanatory, I think. I am trying to find some crystalline phosphoric acid, but no dice. I have found some on Sigma, but I am fairly cranky about the price.

Also, any used glassware for sale would be greatly appreciated.

If you have the requisite equipment, it can be made from ordinary 85% stuff by evaporation. The preparation is in Brauer.

It's better to buy some P4O10 and make it yourself.

I have worked previously with some polyphosphoric acid what was exactly like honey, except that after it my lab coat looked like after a war.

The problem with crystalline and highly concentrated phosphoric acids, that they absorb water too fast and if you are not lucky, then the crystalline H3PO4 will turn into a viscose oil. Even if it absorbs traces of water it's melting point (circa 40Celsius as I remember) will go down to 20-10-0.




I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/
-Pictures from chemistry, check it out(:
