When ordering SN what should I say my purpose is?

[Theman]

I spoke to a dealer and some other user told me that I have to say that if asked for the purpose of buying,I should say that I need it for making insecticides or fertilizers.But they asked me for an insecticide or pesticide license.Can I say that I'm making pesticide or insecticide at home or will the license only be available to people who produce it in factories?Do people make insecticides at home with SN?Can someone guide me on this?

Curing meat.

 

[Theman]

Curing meat.

But meat curing needs only 6-7 percent purity,right?Correct me if I'm wrong.

Probably but better than making fertilise. I can't think of anything else, sorry

 

[CW36]

Curing meat, specifically Peking duck.

The dealer I spoke to gave me these details about the SN.Is the SN appropriate?

If it was 97% yeah it would be alright. You sure he's legit?

Yeah,I guess.He seemed to know the various uses of SN.

Well you tell him you're curing meat, that's what's it's primarily for.

 

[MyChoiceAlone]

i guess they they will be be shut down soon as well. i don't know if that's the name of the actual site but to just put it in your title?

My most sincere apologies.. Will be careful in future.

He won't ask for any license or give me a lower percentage of SN,right?I could also tell him that I'm buying it for doing a science experiment for a YouTube channel right?

 

[lokabe82]

Be careful if you're telling them that you are using it to cure meat. When I told my source this, they took the liberty of switching my order to the food grade stuff

Isn't food grade good enough according to Stan's guide?

 

[jessisme]

Yeah,I guess.He seemed to know the various uses of SN.

How much SN is he trying to sell you and how much is he charging you for it? How much to ship? I got 250g for $35.00 free shipping. It seems like he is putting a suspicious amount of effort into a presumably small sale.

This is true, but it's still possible to use pure SN for curing and I think it was probably more common before SN became closely monitored in many places. I saw a chef's YT video (I assume it was old, but still valid) in which he discussed preferring to use SN straight rather than pre-formulated curing salt mixtures. I don't remember his reasoning but I'm just saying that it's possible for home curers to use pure SN and it's probably possible to find old recipes that call for it, whether online or (likely) in print. Just saying this as an avid home cook who is into preservation and fermentation (not a pro or expert by any means).

Back when I considered SN instead of just using a gun (American), I had this whole thing written out about using industrial purity SN (+90% or more) for phosphating metal to acquire it.

Metallurgically it's also called "parkerizing" or "pickling". In simple terms, you immerse steel in a solution of phosphoric acid and sodium nitrite, along with other trace elements like zinc and manganese. The solution includes sodium nitrite to consume the hydrogen in the reaction; otherwise the hydrogen slows down the reaction by forming bubbles. Parkerizing a metal item increases its corrosion resistance and makes it last longer; ideal for things with a lot of mechanical friction like guns.

If you're in America like me, just claim to be a solo gunsmith who's going to parkerize some guns. Any vendor will believe you easily; parkerizing guns is extremely common.

If you're not in America, you could get away with just saying you're a machinist or a mechanic looking to phosphate-finish some parts. You could also claim to be an amateur toolsmith who wants to try phosphate-coating some knives or hammer heads. This might require a bit more specific but I can't imagine any other vendors asking more detailed questions than that unless they were really suspicious.

Thanks for this post :) It was very informative.

It may be, but personally I'd rather use the maximum I could get my hands on than risk failure

 

[jonward55]

Food grade is fine as long as it's 100% Nitrite and NOT Nitrate and has a purity of at least 95%, mine is 98%.

I know that it is fine and would work, but my anxiety gets me all worked up about it and so I always take a "better safe than sorry" approach

 

[Theman]

Can anyone recommend some experiments to do with sodium nitrite?I told my supplier that I'm having a YouTube channel where I do scientific experiments.So if he asks me any more questions,I want to be prepared.

can i pm you for the source of your SN?

As in 6%?

I think this is the video you're referring to? Not a bad excuse imo...

 

[PrettyPotato]

Dunno if this helps anyone, but sn is used for lots of things other than curing meat.
Curing is possibly the worst excuse to use as it needs such a low concentration of sn (ie food grade, not lab grade).

Here is a fairly comprehensive list from a BASF MSDS doc. Textile dying or technical uses would seem quite plausible for lab grade sn.

In the food industry
Sodium Nitrite for Pickling Salt (E 250) may be employed as a preservative for the production of nitrite pickling salt only in accordance with the provisions of the permitted additives regulations, EC Directive 95/2 or the Code of Federal Regulations (21 CFR) of the Food and Drug Administration or other local guidelines – restricted to a few foods and in the maximum amounts specified there.

In the chemical and pharmaceutical industries
For the manufacture of azo dyes, diazo compounds and nitroso isonitroso compounds. For flushing butadiene tanks and as a component of heat transfer salts.

In textile dyeing and printing
For diazotisation in the manufacture of azo dyes. For oxidising dyeings and prints with leuco vat dyes. To protect against overreduction in dyeing and printing with certain vat dyes. For the accelerated oxidation of vat dyes that are difficult to reoxidise. For bleaching natural fibres.

In the metal industry
As an accelerator in cold phosphating. For the production of baths for the bluing of steels. For the bronzing and quenching of steel. In descaling steels and cast iron. As an additive to alkaline pickling baths for aluminium and aluminium alloys and for neutral cleaning and passivating baths. As an auxiliary in the treatment of tinplate.

In the construction industry
As an additive in the manufacture of concrete to increase its strength and as a corrosion inhibitor in reinforced steel.
As a corrosion inhibitor for iron, steel and water cooling circuit systems.

In the rubber industry
As an auxiliary for the production of rubber as hardener, accelerator, retarder and anti-ozonant.

In the chemical-technical industry
For the manufacture of corrosion inhibitors and corrosion-inhibiting papers. In the manufacture of aqueous emulsion paints. As an additive to enamel frits and for the manufacture of products for preventing corrosion of heating oil storage tanks. In cutting and drilling oils, in hydraulic fluids and in lubricants. In the oil industry.
For stabilising the colour of vinyl resins.

Chemical research (for bio genetics) would be my line at this moment. But there are way better ones. I would say it is for some chemical research project or something which is believable

 

[Jet Black]

In some Asian countries people use SN to cure food, back then it was popular from where i live. In fact, the curing process itself produces small amounts of SN. I'm not so familiar with it, you might need to do a little research to back it up.
