Methods For Identification Of Organic Chemicals

In the process of drug production, research and testing, the separation, purification and identification of organic compounds are often encountered. Identification, separation and purification of organic compounds are three related but different concepts.
The purpose of separation and purification is to obtain purity from the mixture, but the requirements are different, and the treatment methods are different. Separation is the separation of the components of a mixture. In the separation process, a component of the mixture is often transformed into a new compound through a chemical reaction, and it is reduced to the original compound after separation. There are three cases of purification, one is to try to convert the impurities into the required compounds, the second case is to separate the impurities into another compound through the appropriate chemical reaction (the separated compound does not have to be reduced), and the third is to separate by physical methods (liquid separation, chromatography, etc.).
Identification is based on the different properties of a compound to determine what functional group it contains and which compound it is. For example, to identify a group of compounds, it is necessary to determine which compounds are each.
