Изобретение относитс - к способу получени молочнокислых солей циркони или гафни , которые могут найти применение в парфюмерной и косметической промышленности .The invention relates to a method for producing lactic acid salts of zirconium or hafnium, which can be used in the perfumery and cosmetic industries.
Известен способ получени органических солей циркони , гафни и титана, заключающийс в том, что свеже осажденные карбонаты вышеуказанных металлов обрабатывают соответствующей кислотой. Полученный продукт выдел ют известным способом и сушат при 60-80 С.A known method for the preparation of organic salts of zirconium, hafnium and titanium, which consists in the fact that the freshly precipitated carbonates of the above metals are treated with a corresponding acid. The resulting product is isolated in a known manner and dried at 60-80 ° C.
Недостатком известного способа вл етс необходимость предварительного осаждени карбонатов металлов, а также недостаточно высокий выход продукта.The disadvantage of this method is the necessity of preliminary precipitation of metal carbonates, as well as an insufficiently high product yield.
G целью исключени стадии осаждени карбонатов и упрощени прсщесса, а также повышени выхода продукта предложено вести процесс в присутствии 1,5-кратного избытка молочной кислоты с последующим высушиванием продукта при температуре не выше 45 С.The goal of eliminating the stage of carbonate precipitation and simplifying the process, as well as increasing the yield of the product, is to conduct the process in the presence of a 1.5-fold excess of lactic acid, followed by drying the product at a temperature not higher than 45 C.
Пример. К водному раствору хлорокиси циркони концентрацией 0,5-1 ,0 моль/л прибавл ют при перемешивании 40%-ный раствор молочной кислоты из расчета 3,3 г кислоты на 1 г двуокиси циркони . Смесь вьщерживают до полного выпадени осадка, который отфильтровывают и промывают бидистилл том до полного удалени хлорид-иона в промывных водах и сушат при температуре 45°С. Выход по элементу составл ет 95%.Example. A 40% solution of lactic acid at the rate of 3.3 g of acid per 1 g of zirconium dioxide is added with stirring to an aqueous solution of zirconium oxylate with a concentration of 0.5-1.0 mol / l. The mixture is precipitated until precipitate is completely precipitated, which is filtered and washed with bidistillate until the chloride ion is completely removed in the washings and dried at 45 ° C. The element yield is 95%.
Пример 2. Аналогично примеру 1 из хлорокиси гафни и молочной кислоты из расчета 1,9 г кислоты на IHfOj получают оксилактат гафни . Выход его составл ет 90%.Example 2. Analogously to example 1, hafnium oxychloride and lactic acid based on 1.9 g of acid per IHfOj, hafnium oxylactic is obtained. Its yield is 90%.
