ammonium sulfamate

[Turtle]

this came up in another thread as an herbicide, but now unavailable so i gotta know how difficult it would be to make your own ammonium sulfamate at home?

wiki says:

It is a salt formed from ammonia and sulfamic acid.

ammonia is easy to get. how easy is it to get sulfamic acid? (i see sulfamic acid is what makes scrubbing bubbles scrub. )

Sulfamic acid - Wikipedia, the free encyclopedia

this article describes a solid rocket propellant made using ammonium sulfamate, but says potassium sulfamate is preferred and they detail how to prepare potassium sulfamate. http://www.sid.ir/En/VEWSSID/J_pdf/84320080110.pdf

anyway, enquiring minds want to know.

Ammonium sulfaMate (H6N2O3S)- a very good and safe herbicide for trees and tough woody weeds and compost accelerator is easily available from horticultural textiles and products garden netting ground cover frost protection windbreak netting uk - you will be re-directed to a website relating to garden-products. It should not be confused with Ammonium Sulfate - a fertilizer. Ammonium SulfaMate will breakdown in the soil to a nitrogen rich fertilizer - Ammonium Sulfate.
I have come across many uses for Ammonium SulfaMate, but being a rocket propellant is not one of them - please tell me more! Ammonium SulfaMate is generally regarded as non-hazardous for transport purposes.

Sulfamic acid is quite aggressive and we found that it stripped the Chromium out of the Stainless steel flasks when we first made Ammonium Sulfamate - leaving us with a lovely green coloured solution. The reaction is exothermic and not one for trying at home! Sulfamic acid can be used as a disinfectant (Foot and Mouth), a de-scaler in kettles and to clean masonary. Be careful when using as it can produce dangerous gases.
Sulfamate is also spelled as sulphamate.

would a glass vessel be better then? the above link when describing making potassium sulphamate, says they packed the reaction vessel in dry ice & dichloromethane.

anyway, i'm not planning to make it myself, just curious because another guy posted that he can't get any ammonium sulfamate and wants to kill horestails with it. apparently it's no longer approved as an herbicide, as your link makes clear by saying it's only approved as a compost accelerator now. silly human bags of water.

A 1kg / 5l solution is ideal for killing Marestail. Add a dash of Fairy liquid to act as a wetting agent. Repeat twice a week until eradicated.
