How to increase the content of 3-methyl-2***formic acid

How can the content of 3-methyl-2-***formic acid be increased by nitrating it using formic acid and 98% nitric acid? What should be noted? Are there anyone who is familiar with this product? Give some advice
To increase the content of 3-methyl-2***formic acid, the following aspects can be considered: 1. Optimizing the conditions of the nitration reaction, including reaction temperature, reaction time, the molar ratio of nitric acid to m-xyleneformic acid, and stirring speed, in order to ensure a more complete and selective nitration reaction. 2. Use high-purity raw materials to minimize the interference of impurities on the reaction. 3. Appropriate post-treatment methods, such as distillation, crystallization, washing, and drying, are employed to purify the target product. 4. Conduct laboratory pilot tests to identify the optimal reaction conditions and process flow through repeated experiments. 5. If conditions permit, the use of a catalyst can be considered to improve the selectivity of the nitration reaction. Note: When handling strong oxidizers such as nitric acid, strict safety procedures must be followed to prevent dangerous incidents. .
This is an issue related to process optimization; pilot tests are required, and different conditions need to be tested. Only by evaluating the data from these tests can specific process conditions be determined. Different reactor volumes, different material ratios, different operating temperatures and pressures as well as the state of the medium in the reaction system, the addition of materials and the separation of materials after the reaction can all have an impact on the results.
Hello! Pilot tests were conducted earlier, during which the ratio of nitric acid to m-fumaric acid as well as the temperature were adjusted, but the purity level could only reach around 97%; it was not possible to achieve 98% purity
