New method for preparing ruthenium nitrosylnitrate solid

Abstract

The invention discloses a new method for preparing ruthenium nitrosylnitrate solid. The method comprises the following steps of: (1) reacting ruthenium trichloride and sodium nitrite to synthesize ruthenium nitrosylchloride intermediate; (2) reacting the intermediate and silver nitrate to obtain ruthenium nitrosylnitrate solution; and (3) extracting the ruthenium nitrosylnitrate by using diethyl ether, and evaporating the diethyl ether by using extraction liquid to obtain the ruthenium nitrosylnitrate solid. The method is high in yield, is easy to operate and control, and is suitable for large-scale production, and the product has high purity and low impurity content.

AI Technical Summary

Benefits of technology

This patented technology allows for efficient manufacturing of pure ruthium oxynitride with very good quality at an affordable cost. It involves producing it through a specific chemical reaction called ruthiunnitrooxyacid or Ruthenic Acids that produces highly reactive oxygen radicals from ammonia gas. These free radicals then react quickly form stable compounds containing atomic rhenium.

Problems solved by technology

This patents describes different ways to make pure metal oxides like platinum (Pt), rhodium (Rh). These materials can be used with various chemical processes including those involving carbon monoxide reduction reaction (CO_2). However, these techniques have limitations when making them into industrial products because they require expensive starting metals. Therefore, researchers aimed towards developing new types of rhenium based catalysis called ruthenic nitrosonitride (RuNbONa)).
