Description
Изобретение относитс к способу получени оксибромида висмута, используемого , в частности, в аналитической химии.The invention relates to a process for the preparation of bismuth oxybromide, used in particular in analytical chemistry.
Известен способ получени оксибромида висмута гидролизом водой трибромида висмута при 95-lOO C l3A known method for producing bismuth oxybromide by water hydrolysis of bismuth tribromide at 95-lOO C l3
Недостатками способа вл ютс загр знение оксибромида висмута продуктами побочных реакций и невысоки выход 50-60%.The disadvantages of the method are the contamination of bismuth oxybromide by the products of side reactions and a low yield of 50-60%.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ получени оксибромида висмута, включающий взаимодействие нитрата висмута с бромидом щелочного металла в присутствии буферной смеси на основе уротропина и азотной кислоты с последующим отделением осадка, промывкой и сушкой его 2.The closest to the invention to the technical essence and the achieved result is a method for producing bismuth oxybromide, including the interaction of bismuth nitrate with an alkali metal bromide in the presence of a urotropine-based buffer mixture and nitric acid, followed by separation of the precipitate, washing and drying it 2.
Недостатком известного способа вл етс загр знение продукта нитратом висмутила вследствие гидролиза соли висмута, что не позвол ет иметь 100%-ный выход продукта и использовать его в аналитической химии .The disadvantage of this method is that the product is contaminated with bismuthyl nitrate due to the hydrolysis of the bismuth salt, which does not allow for a 100% yield of the product and use it in analytical chemistry.
Цель изобретени - повышение выхода продуктаThe purpose of the invention is to increase the yield of the product.
Поставленна цель достигаетс The goal is achieved
тем, что согласно способу получени оксибромида висмута, включающему взаимодействие водного раствора нитрата висмута, предварительно смешанного сманнитом, с бромидом щелочного металла при рН 5,0-5,2, в присутствии буферной смеси на основе уротропина и бромистоводородной кис лоты при соотношении уротропина и бромистоводородной кислоты, равномAccording to the method for producing bismuth oxybromide, which includes the interaction of an aqueous solution of bismuth nitrate, pre-mixed with smannit, with an alkali metal bromide at pH 5.0-5.2, in the presence of a bumper mixture based on urotropine and hydrobromic acid at a ratio of urotropine and hydrobromic acid equal to
1:(О,008-0,012), отделение осадка, промывку и сушку его.1: (O, 008-0.012), separating the precipitate, rinsing and drying it.
Это позвол ет получать продукт с 100%-ным выходом, что подтверждено данными химического и рентгеноструктурного анализа и данньоми электрон номикроскопического исследовани . Вли ние соотношений компонентов буферной смеси на выход продукта показан в таблице.This makes it possible to obtain a product with a 100% yield, which is confirmed by chemical and X-ray structural analysis and data and electron microscopic examination. The effect of the ratios of the components of the buffer mixture on the product yield is shown in the table.
