2018年10月25日 · The solution of sodium ethyl sulfate can be concentrated on the water-bath without appreciable hydrolysis, and the sulfate finally crystallized out. Place 40ml (32g) of rectified spirit in a 250ml round-bottomed flask, and slowly add. 16ml (30g) of concentrated sulfuric acid, keeping the liquid in the flask well shaken throughout the addition ...

2016年2月1日 · Once I have anhydrous ethyl sulfate I naturalize it with anhydrous sodium carbonate to get the sodium salt. No byproducts are formed besides carbon dioxide so what I can expect is a moist clumpy mass of sodium ethyl sulfate that will be contaminated with ethyl sulfate and sodium carbonate.

2022年9月3日 · Sodium ethyl sulfate is needed for that Nitroethane reaction, but I just want to discuss the Sodium Ethyl Sulfate, specifically the part where i i suck at life. Note:I used 75.5% grain alcohol because my local liquor stores ALSO suck at life but i figured the decahydrate would suck all teh h20s up.

2024年9月26日 · making sodium ethyl sulfate from spent acid-ether reaction mixture Since sodium/calcium ethyl sulfate is a moderately useful reagent, and people have such a tough time getting decent yields as it were, i thought it might be a good idea to neutralize and save the spent reagents after producing diethyl ether from sulfuric acid and ethanol since the reaction …

2016年10月4日 · Methyl hydrogen sulfate is probably a much stronger alkylating agent than the corresponding ethyl one, and might be a better one to start with. There are some posts where I've seen people heating sodium ethyl sulfate strongly enough to make DES, apparently without realizing what they had just made. I couldn't help but cringe a bit.

2018年7月4日 · I'd expect calcium ethyl sulfate to act similarly though it undoubtedly doesn't react quite the same. The potassium salt is said to be easier to crystallize. I read recently in an old edition of Systematic Organic Chemistry that it's possible to distill acetonitrile from a melt consisting of sodium ethyl sulfate and potassium cyanide.

2017年12月1日 · It's definitely sodium ethyl sulfate, and I think 90% is a good estimate of the purity. I did another run, this time neutralizing to pH 8 (instead of 9) and filtering the solution at 500 mL. I got slightly less product, and it appears that slight decomposition took place, so the product is light tan instead of nearly white.

2017年12月1日 · You can get a reasonably pure product if you filter all of the salts from a saturated solution of the sodium ethyl sulfate before removing the rest of the water. Crystals taken early on in evaporating the saturated solution will be translucent or perhaps even clear when wet if you use extremely pure reagents.

2023年7月25日 · Ethyl acetate: Drying with anhydrous sodium sulfate, ethanol removal can be facilitated by salting out using potassium carbonate, followed by distillation of the ethyl acetate layer over anhydrous magnesium sulfate. Phosphorus pentoxide; Isopropanol: Salting out to 91% using sodium chloride, followed by salting out to 100% using sodium ...

2017年11月1日 · The crystals of impurities obtained while concentrating a solution of sodium ethyl sulfate, for me, have had different properties... some have been deliquescent, some have had basically neutral pH, some have been sludges that are hard to filter, some flakes, some crusty substances that creep up the side of the flask, etc.
