The icelike crystals of glacial acetic acid were created and photographed by Prof . David Gingrich of the University of Potsdam.

Using nr 10, I made a close-up cut-out of Nr 10, to show that glacial acetic acid can be something dazzling, and not boring-stuff-in-picture.

The 5-methyl group can be variously oxidized to chloromethyl, aldehyde, or carboxylic acid functionality by the use of stoichiometric sulfuryl chloride in glacial acetic acid.
14.
To this solution is added 1 mL of water for hydrolysis to take place and then several drops of 0.2 % iodine in glacial acetic acid.

At that time, Germany was producing 10, 000 tons of glacial acetic acid, around 30 % of which was used for the manufacture of indigo dye.
16.
By 1910, most glacial acetic acid was obtained from the milk of lime, and the resulting calcium acetate was then acidified with sulfuric acid to recover acetic acid.
17.
Modern practice is to add the oxime solution resulting from the nitrosation and the zinc dust gradually to a well-stirred solution of ethyl acetoacetate in glacial acetic acid.
18.
It crystallizes in large plates, which melt at 98.5 �C and boil at 390 �C . It is readily soluble in warm ether and in hot glacial acetic acid.
19.
Since the CH 3 COOH 2 + ion readily donates its proton to a base, a solution of perchloric acid in glacial acetic acid functions as a strongly acidic solution.

The Martinet dioxindole synthesis proceeds with an alkoxyaniline, 3, 4, 5-trimethoxyaniline, which reacts with an oxomalonic ester in glacial acetic acid to synthesize 2-carbethoxy-4, 5, 6-trimethoxyindoxyl, 2-carbethoxy-3, 4, 5, 6-tetramethoxyindole and 4, 5, 6-trimethoxy-3-hydroxy-3-carbethoxyindole.
