What is best way to remove amines from wood tar
But how a amine should be removed by dilution. Lighter fuel will dissolve more hydrocarbons as polar amines.

Use extraction with hydrochloric acid. Amines will react to ammonium compounds soluble in aqueous Phase.

Mixing acid solutions to maximum concentrations with water.
Yes it does
-
Mixing acid solutions to maximum concentrations with water.
Check the solubility of the acids. That is the maximum what can be dissolved. Citric acid 605 g/l max. Sulfamic acid 181 g/l max. For cleaning purpose 100 g/l is efficent For high end coffee machines read the datasheet of the device. Some internals can be destroyed by acids.

Nitration Help Needed
It is not clear what you want to know. You do a nitration of this both mixtures? Why not separate first? You asking for Aminogroup? The nitration guide first to Nitro products. Phenyl, Benzyl- and Bromine guide to 2,4,6 if available. Nitro to 3 and 5. An Amino group hat to be obtained by reduction.

Re: Magnesium bisglycinate + citric acid = ?
Magnesium stands as Mg2+. But glycin will be pushed out and replaced to citrate.

Unknown substance in Crystal growing solution
Question is also what is the pH of the water. Normaly some Drops of H2SO4 avoid this phenomena.

Reduction of Dihydrouridine using Sodium borohydride or potassium hydroxyde
The aminale RCH(OH)NHR' is also not very stable according Erlenmeyer.

Reduction of Dihydrouridine using Sodium borohydride or potassium hydroxyde
Here a paper about it https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3001720 Borhydride reduce the Uracil amid part. KOH do a hydrolysis of amid.

Doubt silica gel
This is also my opinion.no Trolling please.

Doubt silica gel
Sorry,it will not get better, if you ask everytime the same question again. The answer nobody knows.

A question about gunpowder
I am talking about the Mercury fulminante and the nonsense put it on a hammer on a piano. This is the same like what Nobel did as he add diatomaceous earth to Nitro glycerine to make it more safe known as dynamite. To make a explosive with an Additive more safe against Radio waves is still a funktionell bomb.

Sorry, I realy cannot understand that the Mod. or Admin. let this Thread running.

A question about gunpowder
No discussion about explosives, poisons, drugs, chemical warfare

Doubt silica gel
Like answered in the other forum, if you dont want to exchange the silica gel , then you also dont need it.

Anti Iron Chemical
By the way the link guides to a side, where you have to register and download for big files. This is commercial and should be not permited. The rest of discussion is also trolling. An admin should close it soon.

Decarboxylation
I think at that temperature everything will be cracked.

I need help understanding chemistry.
If you start with sodiumchloride, then you create sodiumhypochlorite. To get the free HClO the pH has to be lowered this can be done with cheap vinegar. During electrolysis the chlorine would also react with acetate and form some poisson chlorinecarbon compounds, like chloroform, chlorineacetate and others.

I need help understanding chemistry.
I dont know which machine you talking about. Again to get good efficency, the NaOH produced at cathode has to react the chlorine produced at anode. To get best results the solution should be stired or the electrode are set very close together.

Stryring would increase the efficency. If the solution is not stired, then chlorine gas will escape. Also can read above in the text from Studiot @ studiot Deacon process is a method to obtain chlorine by burning of HCl at Temp 450 ° C 4 HCl + O2 => 2 Cl2 + 2 H2O This has nothing to do with electrolysis of hydrochloric or sodiumchloride. This works at RT.

Generally the hypochlorous acid HOCl will be obtained, if chlorine is immersed into water. Cl2 + H2O <=> HOCl + HCl So if sodiumhydroxide is present then you would get the salts by neutralisation. Cl2 + 2 NaOH => NaClO + NaCl + H2O So if you use NaCl solution and do electrolysis then you would get on Anode side 2 Cl- => Cl2 + 2 e- and on cathode side 2 Na+ + 2 e- + 2 H2O => 2 NaOH + H2 If you stir this solution then the NaOH and the Chlorine will mixed together and you can obtain the solution above described. The amount is depending at least how much current you use. The vinegar has not much effect on it. Solution is more acidic and more conductiv. If HCl is used also HOCl can be optained, but its more unstable, because no NaOH present.

Solubility of glycine
Glycerin has 3 OH group which support the solubility, because of Hydrogen bridge bonding.
-
Solubility of glycine
In water its soluble 225 g/l, so it will be also soluble in Glycerin. This thread is 9 years old , please open a new thread next time.

Because Cobalt salts are carcinogen, it's not available. Water free CuSO4 is white and change to blue if water is present.
