Can anybody please tell me that what happens if I mix the ammonium hydroxide in a larger quantity with the formaldehyde, or vice versa, to make the hexamine. Will the yield be affected, will I even be able to get the hexamine, or what? Cause I got the ammonium hydroxide, but I dont know its concentration. I also tried it by mixing the ammonium hydroxide(200 ml) and formaldehyde(40 ml), and I dried the water on the stove and got white crystals of something. What might that be?

Add formaldehyde into 1 volume of ammonium
hydroxide, add, stir and smell a little, when the ammonium smell has nearly gone but still a little smell, record the amount of formaldehyde you have added, keep the ratio
and you can use it for mixing these two solutions of the same origins.

You will not want extra formaldehyde remaining in your product, cuz formaldehyde
react violently with oxidizers, nitric acid
for example, add a few drop formaldehyde into
nitric acid and it fumes NO2 like volcano, but that is also the way of making "red fuming nitric acid".
