Liquids pouring

According to Ellis, the melting-point is 19-5°. The specimen was partially melted and the liquid poured off three times, and the product was twice reciystallised from ether. Private communication from the laboratories of Messrs.. 4. Boake, Roberts, Co., Ltd.). 

The solvent was evaporated off under reduced pressure, and the residual gum refluxed with concentrated hydrochloric acid (50 g) for 6 hours. The solution was aliowed to cool overnight. It was filtered from the phthalic acid crystals, and freeze-dried, and to the pink residue was added acetone (160 g) and ethyl acetate (50 g). The mixture was left in the cold room overnight and the clear pink supernatant liquid poured off. The pink gummy hydrochloride remaining in the flask was dissolved in water (20 g), saturated sodium acetate solution added until precipitation was complete, and the product collected and dried in a desiccator. The crude p-bis-(2-chloroethyl)-aminophenylalanine (3.6 g) was crystallized from methanol giving colorless needles, MP 172° to 174°C (decomp.) of p-bis-(2-chloroethyl)-aminophenylalanine. 

Combine all the ingredients, except the lime, in a blender and blend until you have a frozen liquid. Pour into a hurricane cocktail glass. (For a thicker drink, omit a few ice cubes.) Garnish the rim with a lime slice.

The flask is withdrawn from the flame and the liquid poured off, the wool being repeatedly washed with cold water in the same vessel and then boiled for 5 minutes with 100 c.c. of water acidified with hydrochloric acid. The latter is then decanted off and the treatment repeated until a water remaining colourless on boiling is obtained. 

Girard s test. 50 c.c. of the wine are neutralised with 10% ammonia (D 0-960), a further quantity of 5 c.c. of the same ammonia solution being added and the liquid poured into a separating cylinder of about 100 c.c. capacity. 15 c.c. of amyl alcohol are added and the whole shaken slowly, to avoid emulsification, for about 10 minutes. After settling, the liquid below the amyl alcohol is run off and the alcoholic liquid washed three times with water (100 c.c. in all), filtered through a small dry filter and... 

Many fires and explosions have resulted by ignition of the vapor from liquid poured down laboratory sinks. Highly volatile and highly flammable. The vapor may ignite on contact with steam pipes, especially if rusted.3... 

Solutions. Wear goggles and protective gloves and clothing. Estimate the weight of doxorubicin in the spilled liquid. Pour over the spill 3 M sulfuric acid solution (17 mL of concentrated sulfuric acid slowly added to 83 mL of cold water) containing 4.7 g of potassium permanganate, allowing 100 mL of solution per 50 mg of doxorubicin. Allow to react for at least 2 hours. Decolorize with a saturated solution of sodium bisulfite. Absorb the liquid on a 1 1 1 mixture of soda ash, clay cat litter (bentonite), and sand. Scoop the mixture into a pail of cold water. Decant the liquid into the drain with water and discard the solid as normal refuse.4-6... 

As an alternative method of procedure, the following may be substituted for Steps 4 to 7 inclusive of the above process. After distilling the benzol, the tarry mass may be stirred directly with 2000 mL of hot 0.3 N NaOH with a mechanical stirrer. The suspension is chilled and the supernatant Liquid poured or siphoned off. Repetition of the extraction two or three times is advisable. The alkaline aqueous solution is then extracted five or six times with 400 mL portions of sulfuric ether, thus transferring the hormone to ether solution. After distillation of the ether the residue is steam distilled as long as a distillate other than water is obtained. The condensed water is removed by vacuum distillation and the small amount of dark tarry residue leached 5 times with 50 mL of hot 0.3 N NaOH. This solution is filtered and the filtrate extracted with sulfuric ether (100 mL, 6 times). The ether solution is distilled and the residue leached with cold 0.3 N NaOH using 20 mL five times. This alkaline solution is filtered and extracted with 50 mL of sulfuric ether five times. Upon distillation of the ether and solution of the residue in a small quantity of hot ethyl alcohol, the hormone separates in semi-crystalline balls which may be filtered off. A further quantity is obtained by adding 3 volumes of water to the alcoholic solution. It may be recrystallized from 25% aqueous ethyl alcohol or from 25% aqueous acetone or from any of the following chloroform, benzol, ethyl acetate, ethyl ether or petroleum ether. The final product consists of colorless crystals which, when crystallized from dilute alcohol, possess a distinct rhomboid outline. The crystals melt at 242-243°C (248-249°C corrected) with some decomposition. 

Dissolve 30 grams of anhydrous sodium carbonate in 300 cc. of water. Filter the solution if it is not clear. Pour 250 cc. of this solution into the copper nitrate solution. Stir the mixture and heat to boiling. The solid should turn nearly black. If this does not happen add small portions of the sodium carbonate solution until it does. Boil and stir the mixture for about 3 minutes. Allow the solid to settle in the dish and pour off most of the liquid. Stir up the solid with the remainder of the liquid and pour it into approximately a liter of cold water in a 2-liter bottle. Wash the solid by decantation until the soluble salts are reduced to less than one one-thousandth of the original concentration. (Estimate the volume of liquid poured into the bottle with the solid the first time. Follow Note 5 (6), page 10.)... 

The soln. is transferred into a centrifuge cone containing UaOH to neutralize the KH03 and then 2 drops of a 1 soln. of thlohallde (thloglycollc acid fl-amlno naphthalide) are added. This precipitates the Bl as an organic complex which carries the Fo with it. The soln. Is centrifuged and the liquid poured off. 

A solution of chlorate of strontium makes tho flash a bright crimson. Chlorate of barium, green. Nitrate of potassium, violet. Chlorate of copper, bluo. Any ono of tho foregoing chlorates may bo prepared by mixing a warm solution of tho corresponding chloride with an equivalent quantity of a warm solution of chlorate of potossa the precipitate formed will be chlorido of potassium, and tho clear liquid, poured off, will be the desired chlorate, to be used for saturating the gun-paper. 

It may be conveniently prepared by heating potassium ferrocyanide with 50 per cent, nitric acid solution on a water-bath until a drop of the solution gives no colour with ferrous sulphate. The whole is cooled, the liquid poured from the precipitate, neutralised with sodium carbonate, and taken to dryness. Extraction with water, filtration from the insoluble iron compounds, and crystallisation from the clear aqueous solution yields the salt in ruby-coloured, rhombic prisms. The reactions involved may be represented as follows —...
