OK, Hansje. Let's just make sure, this advance is accompanied by a similar advance in backyard industrial caution. Red oxides of nitrogen are not just scary, they really hurt you.

Wonder if diethyl sulfate or yr. sodium ethyl sulfate wd. function alternatively in this rxn. For that matter, would diethyl sulfate work in the room temperature rxn in DMSO? Think we're onto an easier path to diethyl sulfate, bubbling SO2 through CuCl2 sol'n in ethanol. See

(halfapint: "Re: Dimethyl/Diethyl Sulfate", Chemistry Discourse). Sodium ethyl sulfate, I'm hearing, is sleepy simple: neutralize sulfuric acid in excess ethanol with Na carbonate ("pH-Up") then strip off the ethanol. Ethyl chloride seems cheap and easy, but as a gas, once through and it's gone. Has let's say a low residence time in boiling water. In general, I consider gases as wasteful reagents.
"a proper foaming agent. The rxn occurs in gas-liquid surface. I would also bet that some PTC would bee of invaluable help for it."
Yeah. Trouble is, foam automatically means foaming space. That already means "backyard industrial advance" scale, not "fold up your lab and stick it back under the cabinet" scale. A general-purpose bubble builder is detergent and glycerine, but I don't think we want foam quite that persistent, so we should try dishwashing detergent and ethylene glycol (antifreeze) here.
Why do I visualize a pot of broken glass for this rxn? OK, dig -- the rxn takes place in the liquid-gas interface, right? The film of fluid which runs down a glass surface, has a maximal exposure to surrounding gas, like the surface of a bubble does. Foam seems inconvenient to handle, hard to control, but boiling nitrite solution in a pot full of glass shards (inert packing material: Raschig rings, glass wool, silica gel beads, potsherds, rocks) in a tall pot
without the foam, I could feel more comfortable with gassing from alcohol boiled with HCl. Perhaps there's a middle ground, with just a
little bit of foam in lots of rocks.
"It is somewhat complicated in terms of apparatus, but a technically inclined bee like Half-a-Pint, e.g., can certainly manage it with ease"
Gotta get a workshop. Got to have a dedicated space to work. Tired of breaking glass from lack of elbow room. Don't like building submarine-locker size apparatus.
