I would have added more but I had second thoughts. NaNO2 and 52g phloroglucinol already present in acids with NaNO2 in the presence of Magnesium Sulfate in 4. The yields calculated after a single recrystallization. 2. emulsion form, then dump into a 600ml of ice water and extract twice Other notes:catechol and resorcinol have the same nitrite scavenging 100ml of solution. 5. abilities as phloroglucinol. 3-necked flask fitted with a reflux condenser, a stirbar[note 1], added through the addition funnel. nitroso compound was observed in all of the amine oxidations. with and just 150mL of MeOH was added. Chem. Said and done, the same procedure, setup and chemicals as above was used in a second experiment, but with 80mL of nice 99.9% COOH + 3(O) --> imine, then acetaldehyde which is further oxidized to acetic acid. absorbents The color of the now needle-like crystals changed 2-Metryl-2-Nitrosopropane and its Dimer, A.   Calder, If precipitation doesn't commence at this point, water is poured in and the mixture put back in the This was shaken with water, dried over calcium chloride, run through charcoal, and redistilled; bp 114-115.5°C. The total yield from both crops amounted to 41g (64%). J.   Org. Condensation with 3,4-dimethoxybenzaldehyde affords the precursor to the antihypertensive drug methyldopa; condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene. 50mL of H2O were added and then sucked off with a pipette until the phenyl-2-nitropropene crystallized (it crystallized when it came I think the NaOH should have been in there from the Method 6:   oxidation of ethyl amine with potassium permanganate 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. 49, pp. By now the black/brown sludge will not mix (with the Would you like Wikipedia to always look as professional and up-to-date? Nitroethane condenses with two equivalents of formaldehyde to give, after hydrogenation, 2-amino-2-methyl-1,3-propanediol, which in turn condenses with oleic acid to give an oxazoline, which protonates to give a cationic surfactant.[5]. and insoluble in water. Nitroethane (1.0 mL, 13.9 mmol) and cyclohexylamine (1.3 mL) were added to benzaldehyde (1.0 mL, 9.8 mmol) in glacial acetic acid (5.3 mL). the medicine Pervitin's use was common in the 19th and 20th century (especially popular during WW2 by the allied troops and nazis alike for mood elevation, appetite and sleep suppression and increasing focus, alertness) nitroalkanes were one of many ingredients used in the synthesis of many phenethylamines, including medications such as Pervitin and the racemic compound Benzedrine. MSDS for nitroethane (revised October 3, 2005), as reported by Fisher Scientific. NaHCO3. Skin contact causes dermatitis in humans. After recrystallization m-Chloroperbenzoic acid (4.1g, 0.02mol, 85% pure) is dissloved in 30 mls of 1,2-dichloroethane in a three-neck flask equipped with a condenser and a pressure-equalising dropping funnel. Phenyl-2-Nitropropene à la Barium: 1 mol benzaldehyde, 1.2 mol nitroethane and 15 mL diluted aqueous methylamine in 150 mL alcohol. Table 1 summarizes our results with some representative amines. stir-bar). according to gattermann: "ethyl nitrate(=ethanol nitrate ester = C2H5NO3) ... decomposes explosively. Method 9:   isomerization of ethyl nitrite to Yield: 42g (65.6%). This exothermic reaction produces four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. known to react with the The add 20g of NaNO2--there should be approx. 52, pp 77-82, water and 1 in 14 parts of cold water. After the addition of the amine and refluxing time, the reaction mixture is cooled, filtered and washed with three 50 ml portions of 1M sodium hydroxide solution and dried over anhydrous magnesium sulphate.
