2020年1月20日 · Nitroethane is sold by chemical suppliers, however, since it's a drug precursor, it's extremely difficult for the amateur chemist to acquire this compound. In US nitroethane is a DEA List I chemical and individuals cannot purchase this compound. Preparation. Nitroethane is produced industrially by treating propane with nitric acid at 350

2017年1月9日 · Preparation of nitroethane I ran across this nitroethane synthesis that seems really straightforward and relatively simple. Here is a basic rundown of the procedure. In a 2000ml round bottom 500ml dimethylformamide 30g sodium nitrite This is stirred vigorously for 10min to ensure a thorough mix, then immersed in a cold water bath.

2010年12月4日 · Nitroparaffins like nitromethane, nitroethane, and the two isomers of nitropropane are produced industrially by reacting HNO3 and propane at about 150 psi and 400 degrees C. Now, these two reagents are far more easily obtained than the ones usually referred to for lab-scale syntheses, the only problem seems to be the specialized equipment needed.

2010年3月7日 · Nitroethane from ethanol and nitric acid Since you are in the mood for experimentation here is a patent for making nitroethane from ethanol and nitric acid (and other useful information).

nitroethane to these useful degreasing solvents and refrigerants eliminates their corrosive attack on metals. Some inorganic materials are also soluble in nitroethane. For instance, nitric acid and uranyl ions will dissolve in nitroethane and with it can be extracted from aqueous media and purified. Nitroethane is a solvent for anhydrous

2017年6月4日 · Cryolite, let's calculate for a minute a price of making 1 kg of nitroethane. Suppose we have 70% yield of nitroethane and recycle 95% of silver. 1kg / 75 / 0.7 = 19 moles of silver nitrite required, almost 1 mole of silver is lost, which is approx 100 g. 100 g of silver for every 1 kg of nitroethane.

2013年8月1日 · NITROETHANE: 3 Less Common Procedures Nitro Ethane from Ethyl bromide and Sodium Nitrite 32.5 grams of ethyl bromide (0.3 moles) was poured into a stirred solution of 600ml dimethylformamide and 36 grams dry NaNO2 (0.52 mole) in a beaker standing in a water bath keeping the solution at room temperature as the reaction is slightly exothermic.

2006年10月10日 · nitroethane is also used as a stabilizer for chlorinated hydrocarbons perchloroethylene for example. or trichloroethane (used for drycleaning and as a degreasser think brake cleaner) it's present in a concentration of about 2%, along with nitromethane and nitropropane, and other things like tert-butanol.

2016年3月4日 · Subject: Nitromethane, nitroethane, nitropropane synthesis via industrial route AndersHoveland Hazard to Other Members, due to repeated speculation and posting of untested highly dangerous procedures!

2010年2月7日 · It is a patent that gives the conditions to produce a mixture of 83% nitroethane and 17% nitromethane by vapor phase nitration of propyl nitrite with 50% HNO3 vapor at 400*C (or NO2 at 300*C), at atmospheric pressure. Interestingly, they use an aluminum tube immersed in a molten salt as the reactor. It is advantageous because it results in a ...
