What are you going to use the stuff for? A stink bomb, I suppose. Or you could use it to make thioether complexes of transition metal cations, to which it bonds readily, e.g. to Fe(III) to give an intensely red complex; some of them may have uses as dyes or paint/ink pigments. Another possibility is in organic chemistry to make sulfonium salts, SR3+, by reactions that produce carbonium cations with subsequent electrophilic addition. Mild oxidation would produce diethyl sulfoxide, or more strongly diethyl sulfone, which may have uses as solvents.

yes i had goggles. but i totally forgot the gloves...^^

@JohnWW
first i show this stuff my friends. They want to test the stench.
Maybe some Diethyl sulfone from Hydrogen peroxide.

Awesome videos. The official music of science videos is now 009 Sound System.

I'm glad no one called in a gas leak. How bad was it?

Cool some more videos :)

I thought sodium ethyl sulfate hydrolyzed easily and you use water in your reaction. Could there be significant amounts of ethanol in the product?

yes, thats why my boiling point of the product was at 82°C. DES s boiling pont is at 92°C and EtOH BP is at 78°C. i think they form an azetrop.

Nice home synthesis


But I think it's easier to use ethylbromide. Its preparation does not require conc. sulfuric acid
Or is it easier for you to find the acid instead of NaBr?

i think sulfuric acid is easier to find than NaBr and much cheaper, because hundred million tons are produced every year.

for the preperation of Ethyl bromide i would use H2SO4, instead of NaHSO4.

Warning! This video is wrong, NaHCO3 can not be safely used to basify ethylsulfate because it also generates H2S upon warming! Severe breathing organ damage and death can result.

If I recall from other threads, the member "Myfanwy" actually died while experimenting with hazardous stuff and succumbed of pulmonary edema...

I guess such a tragedy can make anyone take a step back and think whether dangerous syntheses are really necessary and if all precautions have been taken before attempting a hazardous experiment/setup, especially when we're talking about home/hobby chemistry...

I know I'm overly cautious when I say that I don't play with energetic materials and highly poisonous stuff for any reason, and that I take extreme precautions with solvent and toxic salts and solutions. Still, I double and triple check before attempting an experiment to make sure it won't evolve hazardous gases or is overly exothermic. My health, my 10 fingers and my two eyes are just too precious to me.

PS: you should see me when handling concentrated acids... I'm one step away from a space suit LOL...

Pulmonary edema is one of the worst things one can die of. I had the fear I might have been developing this also. Apparently, he made phosgene. This isn't a compound I would ever want to make, for any reason. Myfanwy was young and I think wanted to make it, to conquer it, so to say. To be able to say he made it. Not so much anymore, but I don't mind some controlled pyro experiments once in a while, but keep my distance from dangerous devices used by blasters and military men. Though, early centuries' references treated these subjects of experimentation much more lightly, whereas today one is viewed with much more suspicion.
