The product we are introducing is Factory Supply Dimethylglyoxime with CAS 95 - 45 - 4. Dimethylglyoxime is an organic compound, and its chemical formula is C₄H₈N₂O₂. It is a white to off - white powder at room temperature. The melting point of dimethylglyoxime is approximately 240 - 242°C. It is slightly soluble in water but more soluble in organic solvents such as ethanol, ether, and chloroform. Dimethylglyoxime has high purity in our factory supply, ensuring its effectiveness in various applications.
1. **Analytical Chemistry**: Dimethylglyoxime is widely used as a chelating agent in analytical chemistry. It can form a stable, red - colored complex with nickel ions. This reaction is highly selective, allowing for the qualitative and quantitative determination of nickel in various samples, such as ores, alloys, and environmental samples.
2. **Metal Separation**: It is also used in the separation of metals. By forming complexes with specific metal ions, it can be used to separate nickel from other metals in a mixture, which is important in the metallurgical industry for the purification of metals.
3. **Catalyst Preparation**: In some chemical reactions, dimethylglyoxime can be used in the preparation of catalysts. It can coordinate with metal ions to form catalytically active complexes, which can accelerate chemical reactions.
1. **In Analytical Experiments**: When using dimethylglyoxime for nickel determination in a sample, first, prepare a solution of the sample in an appropriate solvent. Then, add an appropriate amount of dimethylglyoxime solution. Usually, the reaction is carried out in a slightly alkaline medium. After the reaction, the red - colored nickel - dimethylglyoxime complex can be detected by spectrophotometry or other analytical methods.
2. **For Metal Separation**: In a metal mixture solution, add dimethylglyoxime to selectively precipitate the nickel ions. After precipitation, the solid can be separated from the solution by filtration or centrifugation. The separated nickel - dimethylglyoxime complex can be further treated to obtain pure nickel.
3. **In Catalyst Preparation**: In the preparation of catalysts, dimethylglyoxime is mixed with metal salts in a suitable solvent. The reaction conditions such as temperature, pH, and reaction time need to be carefully controlled to obtain the desired catalytically active complex.
1. **Nickel Determination in Environmental Samples**: A research team was studying the nickel content in soil samples near a nickel - mining area. They used dimethylglyoxime to analyze the samples. First, they extracted the nickel from the soil samples using an acid digestion method. Then, they added dimethylglyoxime solution to the extracted solution under alkaline conditions. The red - colored nickel - dimethylglyoxime complex was formed, and its absorbance was measured at a specific wavelength using a spectrophotometer. By comparing the absorbance with a standard curve, they were able to accurately determine the nickel content in the soil samples.
2. **Purification of Nickel Alloys**: A metallurgical factory was trying to purify a nickel - copper alloy. They dissolved the alloy in an acid solution. Then, dimethylglyoxime was added to selectively precipitate the nickel ions. After filtration and further treatment, they obtained high - purity nickel, which could be used for high - end applications such as in the electronics industry.
3. **Catalyst for Organic Reactions**: A chemical research group was working on a new organic synthesis reaction. They prepared a catalyst using dimethylglyoxime and a transition metal salt. By optimizing the reaction conditions, they found that the catalyst could significantly improve the reaction rate and selectivity, providing a more efficient way for organic synthesis.
