Not illustrated. 1892 Excerpt: ... volume of water to which soda solution is added until slightly alkaline. The ethyl bromide, which sinks to the bottom of the vessel, is drawn off by a tap funnel, and is then shaken repeatedly with water. It is separated as completely as possible from water and dehydrated over pieces of fused calcium chloride. The clear liquid after being decanted is distilled on the water-bath, a thermometer being inserted through the cork of the distilling flask. The ethyl bromide distils at 36-40 and may be further purified by a second distillation. 5C.H-(OH) + 5Br + P = 5C., H5Br + H3PO4 + H2O Alcohol Ethyl" Bromide. Properties.--Colourless liquid; b. p. 38-8; sp. gr. 1-47 at 13-5. Determination of Specific Gravity.--A simple method for determining the specific gravity of liquids is as follows: A small glass bottle of about 20--30 e, e, capacity, which can be readily made by the help of the blow-pipe (Fig. 21), is fitted with a cork. The neck of the vessel just above the bulb is narrowed by drawing it out in the flame, and a horizontal mark m etched or scratched on it with a file. The bottle is thoroughly cleaned, dried in the air-bath, allowed to cool and weighed. It is then filled with the liquid, which is poured in through a funnel, the stem of which is drawn out so as to pass through the constricted neck. The bottle is placed in a mixture of snow or pounded ice and a little water and left io hour until the contents have a temperature of 0. The meniscus is now adjusted until it coincides with the mark on the neck of the bottle. If more liquid has to be added this may be done from a small pipette with capillary delivery tube; if some of the liquid has to be removed a piece of bibulous paper may be used to absorb it. The bottle is then corked, dried, allowed t...
