Hi, when Hexamine is mixed with different salts here are the results Please see below and please see these links for the chemical mixtures.
Warning: Hexamine is flammable and toxic besides being an Irritant. It releases formaldehyde too. Prolonged exposure can cause a rash like poison ivy and burns. Wear PPE. With the dyes and materials always bring them to an eco-center since they are bad for the environment.
Hexamine + Silver nitrate << >>> Hexamine Silver Nitrate complex.
3 Chrome (III) chloride +3 Hexamine +33H20 << >> 3Chrome(Hexamine)3(H20)6 + 9H20.
Half of the water molecules are coming from the chrome (III) chloride).
Cobalt Chloride +2 Hexamine +5 H20 <<< >>> Cobalt(Hexamine)2(H20)6 + 4H20.
3 Iron (III) chloride +3 Hexamine << >> Iron(Hexamine)3(H20)6 + 6H20.
Here are just a few examples. I cannot go into every one of these. Look them up if you're interested.
Step 1: Making the Hexamine Compounds and Solutions (Dyes).
For 100 ml of Distilled water (Important) add the following 1 12 g tablet cut in half and wearing PPE (Gloves and Goggles min) dissolve the solution. Hexamine is very soluble and takes 1 hr or so at room temp.
Hexanine reacts especially solution with acids including skin to produce Ammonia and formaldehyde. So always wear appropriate PPE. It causes burns and poison ivy rash. Formaldehyde is considered in the MSDSs, etc to be Level 1 mutagenic and cancer-causing so be sure to use caution.
In a test tube, etc add 5 g of the following: Sodium dichromate, Iron (III) chloride, Sodium metavanadate sol, Potassium ferrocyanide (yellow) and Silver Nitrate. TO each add 10 ml of Hexanine solution.
In clean test tubes add 5 g of each of the following: Sodium ferrocyanide, Iron (II) sulfate, Copper chloride and Cobalt chloride. Then to each test tube add 10 ml of the Hexanine solution.
Then Add 5 g of the following chemicals: Potassium ferricyanide, sodium chloride, and another chemical besides copper sulfate with 10 ml of Hexamine solution.
Finally add each of 5 g of chemical into a test tube: Chrome (III) chloride, Chrome (III) sulfate sulfate, sodium thiosulfate and zinc sulfate.
Here 98 percent of 1-naphthol is added to Iron chloride and a dark purple-blue pigment occurs. Both 1-naphthol and 2-naphthol are used as dyes and make complex dyes. I heard they are pH stable. I am also working with 5-SSA. 5 sulfosalicylic acid in Methanol with Iron (III) chloride and different pHs.
5 g of Iron chloride is added to 5 g 1-naphthol and methanol to get a blue-purple color. If a lot is used it bluer in color. For the others 5 g of Iron (III) chloride is added to Methanol and 5-SSA 99 percent with water molecules. At pH 7 it purple at pH 14 it is orange and pH 1.0 or less it is brown-black color.
The main issue with my dye is the use of Methanol 99 percent instead of 70 percent ethanol this explains the color change partly and the fact is 99 percent with water molecules. Not 100 percent with water may also play a role.
Step 2: Some Sheet Art With Two or Three Dyes Plus Caps and Metal Copper Steel Plate Dye Attempt.
When Methanol in my case is mixed with iron chloride and 5-SSA and pH 1, and Ph 14 the ph of 7 gives different combos of neat art too.
Here some data on Hats too. Pics on cap dyes too are Here.
I tried Normal color Indirect Plating but you need aluminum and dye plus sulfuric acid. A specific dye is also required but this dye would turn brown and would not work well even with electrolysis.
Take a cotton cap and add green tea extract. Then add Naphthol Red conc diluted by 1/4 with 5 drops Methylene blue. This alters the color slightly. Use other methods of dyes to get different colors. Oddly formaldehyde when remaining Iron chloride was added to Hexamine (Some) that cross-linked some cotton. It was well ventilated too.
Step 3: Final Words.
This type of art from complexes dyes as well as the theory behind Hexamine as Organics with Inorganics is Interesting. Hexamine can even from complexes with organic acids and Uranium oxides!! See Link I gave you. It is studied as a delivery system for medicine (Silver nitrate Hexamine) but it effectiveness is unknown right now and it safety is unknown.
The organic dyes are both Iron with organic materials like (Hexamine with different metals, etc) this includes SA, 5-SSA, and Naphthol-1. Other dyes from complexes but I am focusing on metal complexes. Ligands are complexes like Iron with Hexamine but Naphthol with iron I am not sure if that a Ligand it counts as a dye. It could possibly be both but I am not sure about that.
Be careful if you are going to repeat this since Hexamine is toxic and the ferrocyanides must NOT touch any acid salt = potential release of Hydrogen cyanide. Wear PPE (Gloves and goggles or a face shield). These dyes can be at least 5=SA be allowed to evaporate and or sodium carbonate to turn Fe+3 into an Insoluble form breaking the dye (tried it). Then allowing the methanol to evaporate off outside (careful it flammable). This will work for the 1-naphthol, SA or 5-SSA in theory.
In my opinion, all of these chemicals should be disposed of properly at an eco-center.
