NBS (chemical reagent) generally refers to N-bromine amberamide, molecular formula: C4H4bRNO2. N-bromine amberamide preparation method: obtained by tanxamide. Perf the dicen amine into the reaction cooker, add the broken ice and sodium hydroxide solution, and stir and dissolve. In the case of severe stirring and cooling, add a mixture of bromine and tetrachloride, and quickly filter after stirring for 2 minutes. Wash it with ice water to the colorlessness, then wash with a small amount of ethanol, and dry it to get the finished product. Thiel binocarbly acid and ammonia forming ammonium, then heated dehydration to form altericide, and then bromide and refine the finished product. The expansion information: N-bromine amberamide is generally white fine-grained crystals, melting point 172-178 ° C (decomposition), density 2.098g/cm3. Soluble in tetrachloride. Organic synthetic raw materials are used to regulate low -energy bromide reactions, and are also used to produce rubber additives and medicines. Can synthesize bromide medicine. This can be used in the pesticide industry to synthesize the pyromonic bacteria, and it can also be used as a fruit preservation agent and anticorrosive and moldy agent.
