WebSample Preparation. Based on the expected bromine number a known amount of sample is weighed out and dissolved in 50 mL diethyl carbonate. Analysis Blank. The blank is determined using an identical technique as for the sample but using diethyl carbonate instead of the sample. Sample WebBromine is a halogen chemical element and a red-brown liquid at room temperature. It has a pungent smell and causes irritation to the eyes and skin. The market is segmented on the basis of derivatives, applications, and geography. By derivative, the market is segmented into organobromines, bromide salts, and hydrogen bromide.
