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 is used in the S.C. Johnson & Sons, Inc. "Scrubbing Bubbles Fizz-Its Toilet Tablets." ...

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. :doh:

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.

everything i know about that came from the link i posted. >> http://www.sid.ir/En/VEWSSID/J_pdf/84320080110.pdf

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. :shrug:

 

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. :Alien: :hyper:

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.

I may have been the guy looking for ammonium sulfamate for making a refreshing elixir for tending my horsetail.

 

Still have not found a reasonably priced source. I knew about Root-Out; but the price is insane. The typical business move of selling a few cents of a chemical for dollars with a nice brand and package. Way too expensive for my use. Most places I have found that have it are reagent grade. Pricing is the issue with that as well. I have found a small online chemical seller that has some. Although the pricing is a more reasonable $6 a lb, that is still very expensive for spraying as weed killer. Places that have/make it are bulk suppliers and don't do small sales. One generously sent me a sample. It was about a quart of powder and it was enough for one spraying. I am not sure if its effect at this point. Spring will tell. I suspect addtional spraying was need on at least some of the plants. I have a lot of horsetail.

 

If anyone knows of a source willing to sell 50 - 100 lbs of it for an affordable price - that information would be greatly appreciated. I know a guy at a supply company that could deal with a chemical company as a business. That would probably make it a bit easier. But he has not found a source.

We can supply in 25Kg (approx. 50lb) sacks. No problem! The problem may be transport costs. We are in UK where are you?

[alternety]

I am not in the UK. I am on the upper left coast of the US.

Nigel, I am looking to buy a 25kg bag of Ammonium Sulphamate - can you still supply?

 

Thanks
