Alcohol burner, using

Follow this procedure 1. Put 4 tablespoonfuls of coconut or olive oil into the small pot and add 1 test tubeful of sodium hydroxide solution to it. Carefully heat the liquid over the alcohol burner, using a small flame. Stir the mixture constantly and continue heating it until it becomes a thick paste. Caution Be sure you wear goggles. Sodium hydroxide bums skin and spoils clothing. If any sodium hydroxide gets on your skin, wash it immediately with cool water. Remember, too, that the pot should never again be used for cooking. 

You can light an alcohol burner with alehohol in the same way. Never repeat the experiment using the same rod ... 

Be careful with fire. When you use your alcohol burner, have a metal pan under it for safety. 

Now you have a wire gauze pad which can withstand the heat of your alcohol burner, and which will not endanger your fingers while you are using it. To use it, you place it over the ring support and rest on it the container you wish to heat. You will probably want several wire gauze pads.

How to Use an Alcohol Burner. Many experiments require heat, and the alcohol burner is more efficient for this purpose than a candle. Keep the wick clean and trimmed. Whenever the flame is not blue, it is either because the wick is dirty or needs trimming. When you are not using the burner, keep it tightly covered to prevent evaporation of the alcohol. In lighting the burner, strike the match away from you. In putting it out, cover it quickly with the metal cap. After you refill it and before you strike a match, make sure that no spilled alcohol remains on the outside of the jar, on the table, or on your hands. 

Follow this procedure Label 5 test tubes 1 to 5 or label their places in the test tube rack. Fill these 5 test tubes halfway with warm water. Put teaspoonful of sodium chloride into the first test tube, i teaspoonful of talcum powder into the second, and so on, for the next three substances. Do not use the potassium aluminum sulfate yet. If the substance doesn t dissolve right away, heat the test tube over the alcohol burner until it does, or until you are sure it won t. Make out a data sheet similar to this one ... 

Gather these materials A rather large plumber s candle an alcohol burner and a 10-inch piece of glass tubing drawn out to a fine nozzle at one end. Obtain your mother s permission to use the gas stove. If your family doesn t have a gas stove, you will have to omit the parts of the experiment that require it.

It will take the heat from an alcohol burner so it can also be used as a large test tube. Fitted with the right sized stopper with one or two holes, it will have many uses. 

The industrial importance of methanol is due to its oxidation product, formaldehyde, which is a major starting material for the production of plastics. Methanol is used as a fuel in Indy-style racing cars (see > Figure 3.8). It is also used as a fuel in products such as alcohol burners found in camping supplies. 

The methyl alcohol (CH3OH) used in alcohol burners combines with oxygen gas to form carbon dioxide and water. How many grams of oxygen are required to burn 60.0 mL of methyl alcohol (d = 0.72 g/mL) ... 

Place 0 -5 g. of 3 4 5 triiodobenzoyl chloride in a small test-tube, add 0 -25 ml. of the alcohol - ether and heat the mixture gently over a micro burner until the evolution of hydrogen chloride ceases (3-5 minutes). Pour the molten mass into 10 ml. of 20 per cent, alcohol to which crushed ice has been added. Some derivatives solidify instantly those which separate as oils change to solids in a few minutes without further manipulation. Recrystallise from rectified spirit (use 50 per cent, alcohol for esters of methyl and butyl carbitol ). 

Prepare a coil of copper wire by winding several turns around a glass tube. Heat the coil in the oxidising flame of a Bunsen burner for 1-2 minutes and plunge the spiral, whilst still red hot, into a test-tube containing a solution of 1 ml. of methyl alcohol and 5 ml. of water. Stopper the test-tube loosely, cool, remove the wire, and repeat the process two or three times. Observe the odour of the solution and use it (or formalin diluted with water) to carry out the following tests. 

The appatatus consists of a brass cup (See Fig F10), supported by a metal heating plate, XA inch thick and 6 inches in diameter (not shown here). In the center of the plate there is a plane depression l/32 inch in depth, and of just sufficient diameter to fit the cup. There is also a circular opening 2-3/16 inches in diam, cut thru the plate, centering with the center of die above-mentioned depression. The plate is covered with a sheet of hard asbestos board % inch thick, and of die same shape as the metal plate and with a hole cut in the center just to fit the cup. Heat may be supplied from any convenient source. The use of gas burner, electric heater, or alcohol lamp Is permitted, but under no circumstances are... 

Source of Ileal. In the regular laboratory, special gas burners are used. In the home lab, you can use a burner for denatured alcohol. Have a shallow metal pan under the burner for fire safety. 

Using a Bunsen burner or alcohol lamp, warm 100 ml of distilled water. Do not boil. 

Figure 031. This apparatus can be replaced with any standard distillation apparatus, or standard fractional distillation apparatus Alcohol stills can also be used, but may undergo corrosion in the distillation pot due to the presence of sulfuric acid. The diethyl ether should be re-distilled using a standard fractional distillation apparatus, or equivalent. After redistillation, the ether should be stored in a proper container such as a metal can, or glass container, sealed air-tight, and filled to the top (to minimize air gaps), and these containers should be stored in a refrigerator until use. Note the heating mantle portrayed in the illustration can be replaced by a Bunsen burner, hot plate, stovetop, steam bath, or oil bath if desired.
