Applicazione
Sensitive field
Print blueprint: It is the key photosensitive agent in the process of printing blueprint. During the printing process, the light-sensitive paper containing ferric ammonium oxalate is covered on the engineering drawings or other documents that need to be copied. After exposure, the exposed part of ferric ammonium oxalate undergoes a photochemical reaction, and the solubility of the generated substance in ammonia is different from that in the unexposed part. Through the development of ammonia, the unexposed part of ferric ammonium oxalate reacts with ammonia to form a blue substance, thus obtaining the blueprint.
Production of sensitive paper: used to produce a variety of sensitive paper, widely used in printing, plate making and other industries. Its photosensitive properties enable the formation of different gray levels after exposure, so that images and text information can be accurately reproduced.
Chemical analysis
Metal ion determination: As a coordination reagent, it can be used to determine a variety of metal ions. In the determination of calcium and magnesium ions, ferric ammonium oxalate can form complexes with different stability constants. By controlling the pH value of the solution and other conditions, the content of these metal ions can be accurately determined by coordination titration. It is widely used in water quality analysis, ore composition analysis and other fields.
Catalyst field
Organic synthesis reactions: In some organic synthesis reactions, ferric ammonium oxalate can be used as a catalyst. For example, in oxidation reactions, it can promote the reaction between the oxidizer and the organic substrate, improving the selectivity and yield of the reaction. In the oxidation reaction of alcohols, ferric ammonium oxalate can catalyze the oxidizing agent to oxidize alcohols to corresponding aldehydes or ketones, and has certain selectivity for different structures of alcohols.
Polymerization reaction: It also plays a catalytic role in some polymerization reactions. It can initiate or accelerate the polymerization process of monomers and control the molecular weight and molecular weight distribution of polymers. For example, in the polymerization reaction of some acrylate monomers, ferric ammonium oxalate can be used as a REDOX initiator to trigger free radical polymerization of monomers to prepare polymer materials with specific properties.
Other fields
Electronics industry: Used in the electronics industry to manufacture printed circuit boards (PCBS). In the production process of PCB, using the sensitivity of ferric ammonium oxalate, the circuit pattern can be transferred to the copper-clad plate through photolithography technology, and then through development, etching and other processes to produce high-precision circuit graphics.
Pharmaceutical field: In pharmaceutical research and production, ferric ammonium oxalate can be used as an intermediate or reagent. For example, during the synthesis of certain drugs, it can participate in specific reaction steps, introduce desired functional groups or build specific molecular structures. At the same time, in drug analysis, it can also be used to determine the content of certain metal impurities in drugs.
