Abstract

The invention discloses a method for producing nano basic copper nitrate. The method comprises the following steps of: (1) preparing the following reaction liquids: copper nitrate aqueous solution, caustic soda solution and ammonium nitrate solution, and performing ultrafiltration treatment on the copper nitrate aqueous solution and the caustic soda solution; (2) putting the ammonium nitrate solution in a reactor with an ultrasonic stirring device, and feeding the copper nitrate aqueous solution and the caustic soda solution which are subjected to ultrafiltration previously into the reactor for reaction via a mixed liquid high-pressure spraying device; (3) when the pH value in the reactor reaches 6.2-6.3, adding nitric acid and stopping adding until the pH value is in the range of 4.2-4.3; (4) further stirring for 40-60 minutes until the pH value is in the range of 4.3-4.5 and terminating the reaction to obtain a synthetic liquid; (5) standing the synthetic liquid, removing the clear liquid at the upper part in the tank and washing the precipitate using water; and (6) separating the obtained precipitate and drying, thereby obtaining the nano basic copper nitrate. The method is characterized in that the posttreatment process is simplified, the combustion and catalytic performance of the product are good and the application and popularization defects of the common copper nitrate are eliminated.

Description

technical field [0001] The invention belongs to the field of production of basic copper nitrate, and in particular relates to a production method of nano-body basic copper nitrate. Background technique [0002] Basic copper nitrate is an important component material in the gas generating agent of automobile airbags, and it is also a catalyst material that is often selected. The larger the specific surface area of ​​basic copper nitrate products, the stronger the gas production or catalytic ability, so the application prospects of high specific surface area basic copper nitrate products are very broad. However, the common basic copper nitrate product produced by the prior art has a limited specific surface area, and the post-treatment process is complicated, the actual industrial production is difficult, and the yield is low. In addition, the produced product is easy to agglomerate and affects the use effect of the product. The above-mentioned defects limit the popularizatio...
