Production method
1-phenyl-3-methyl-2-pyrazole-5-one is first nitrated at no more than 15 ° C and then refined. The process is:
1. After nitrification, filtration, dilute pickling, and water washing, proceed to the next step immediately;
2. It is hydrolyzed at 50 ~ %℃ in 33% acetic acid, and filtered and washed after hydrolysis;
3. Turn into sodium salt, add sodium carbonate in ethanol and neutralize until the litmus is alkaline, then refine it with water and acidify it with hydrochloric acid to obtain crude product;
4. The finished product is crystallized with ethanol.
Use
1. Can be used as a variety of alkaloids, tryptophan, phenylalanine identification reagent, can also be used to determine strontium, thorium, magnesium, lead and so on.
2. Used as an analytical reagent. Reagents for preparing liquid film electrodes for the determination of atropine and brucine in pharmaceuticals.
3.This chemical can be used to test alkaloids, Tryptophan, Phenylalanine. It is also used to test strontium, thorium, magnesium and lead. Similarly, it can be used as analytical reagent.
