Slowly hydrolyzes in moist air. On small fires, use AFFF,... [Pg.3]

Deghenghi et al studied the reductive alkylation of 16-dehydropregneno-lone acetate in ammonia-tetrahydrofuran using excess lithium and alkyl iodides. Alkylation with methyl iodide followed by reacetylation of the 3-hydroxyl group affords 17a-methylpregnenolone acetate in 20% yield after purification by column chromatography. Ethyl iodide affords the 17a-ethyl analog in 40% yield, but n-propyl iodide affords the 17a-propyl compound in only a 12 % yield. [Pg.48]

A mixture of 10 parts of 7-chloro-4-fluorobutyrophenone, 5.5 parts of 1-(1,2,3,6-tetrahydro-4-pyridyl)-2-benzimidazolinone, 4 parts of sodium carbonate, and 0.1 part of potassium iodide in 176 parts of 4-methyl-2-pentanone is stirred and refluxed for 64 hours. The cooled reaction mixture is filtered and the solvent is evaporated from the filtrate to leave an oily residue which is dissolved in toluene. The toluene solution is filtered and the solvent is evaporated. The resultant residue is recrystallized from a mixture of 32 parts of ethyl acetate and 32 parts of diisopropyl ether to give 1-[1-[(4-fluorobenzoyl)propyll-1,2,3,6-tetrahydro-4-pyridyl]-2-benzimidazolinone hydrate melting at about 145°-146.5°C. [Pg.544]

To a solution of 4 g of sodium in 200 ml of n-propanol is added 39 g of homovanillic acid-n-propyl ester (boiling point 160°C to 162°C/4 mm Hg) and the mixture is concentrated by evaporation under vacuum. After dissolving the residue in 200 ml of dimethylformamide and the addition of 0.5 gof sodium iodide, 26.2 g of chloracetic acid-N,N-diethylamide are added drop-wise with stirring at an internal temperature of 130°C, and the mixture is further heated at 130°C for three hours. From the cooled reaction mixture the precipitated salts are removed by filtering off with suction. After driving off the dimethylformamide under vacuum, the product is fractionated under vacuum, and 44.3 g of 3-methoxy-4-N,N-diethylcarbamido-methoxy phenyl acetic acid-n-propyl ester are obtained as a yellowish oil of boiling point 210°C to 212°C/0,7 mm Hg,... [Pg.1310]

Olivetol. (5-Alkyl Resourcinol) BER 69, 1644 (1936). Mix 25 g of ethyl-3,4,5-trimethoxy benzoyl acetate and 2.0 g of clean sodium in 100 ml ethanol and warm to react. Add 2 g n-propyl iodide (this may be replaced with n-amyl iodide) and heat on a steam bath for 12 hours, then neutralize and remove the ethanol by distillation. Extract the residue with ether, dry, and evaporate in vacuo to get 30 g of the alkyl acetate. Heat 22 g of this acetate in 5% KOH ethanolic solution for 1 hour at 50° and let stand to precipitate 14 g of 3,4,5-trimethoxyvalerophenone. Mix 11 g of the above product with 60 g of sodium in 600 ml ethanol. Warm and after dissolving the sodium add 2 liters of water. M e acidic with HCl acid and remove the ethanol by distillation. Extract with ether, dry, and evaporate the ether in vacuo to get if. g olivetol dimethyl ether. To demethylate this ether add it to 70 ml of hydrogen iodide and heat to boiling and reflux for two hours. Distill and keep the fraction at 160°-170° with 3-4 mm of vacuum applied to the distillation set-up. Yield about 6 g. [Pg.71]

The tinctura iodi of the British Pharmacopoeia is a soln. of half an ounce of iodine, and a quarter of an ounce of potassium iodide in a pint of rectified spirit. P. Wantig found the mol. ht. of soln. —1 941 Cals., and S. U. Pickering —1 714 per 880 mol. of ethyl alcohol. C. Lowig found that alcoholic tincture of bromine is slowly decomposed in darkness, rapidly in light. Alcoholic soln. of iodine, according to H. E. Barnard, are stable in light and in darkness, but according to J. M. Eder they decompose 1000 times more slowly than chlorine water under similar conditions T. Budde has shown that hydriodic acid, acetic ester, and aldehyde are formed, and the electrical conductivity of the soln. increases. J. H. Mathews and E. H. Archibald and W. A. Patrick found a freshly prepared AT-soln. to have an electrical conductivity of 2 4 XlO-6 reciprocal ohms and a sat. soln., 1 61 X10 4 reciprocal ohms at 25°. The decomposition is accelerated by the presence of platinum. The heat of soln. decreases with concentration from —7 92 to —7 42 cals, respectively for dilute and sat. soln. in methyl alcohol, and likewise from —4 88 to —5 22 cals, for similar soln. in ethyl alcohol. The solubility of iodine in aq. soln. of propyl alcohol is not very different from that in ethyl alcohol. [Pg.87]

Two hundred grams of n-propyl iodide are treated with 0 2 per cent, sodium amalgam, in presence of 30 grams of methyl acetate. The resulting paste when treated with dilute potassium hydroxide, then steam distilled, yields an oil which is impure mercury dipropyl. ... [Pg.36]

Isopropyl Series. —iso-propyl mercuric hydroxide is formed by treating the halides with moist silver oxide, and has only been obtained in solution. It reacts with acids, giving rise to the following comj ounds chloride needles, M.jDt. 97° C. bromide needles, M.pt. 98° C. iodide plates, M.pt. 125° C. acetate M.pt. 95° C. cyanide, M.pt. 85° C. sulphide, M.jDt. 60° C. [Pg.43]
