When we do organic synthesis, we will be exposed to many parameters, such as the polarity of the developing agent, the parameters of various solvents, including toxicity, boiling point, solubility, etc. Commonly used solvent miscibles, pressure unit conversion tables, common chromogenic agent configuration and use methods, and nuclear magnetic resonance of various residual solvents. We won't go into all of them. It is still difficult to remember these parameters, and the best way is to be able to summarize these parameters into **, which is easy to query and use. Today for the chemists to sort out the ** of these parameters, the clarity should still be OK, I hope you organic synthesis workers can use it, organic synthesis has to collect a few **details as shown in some of the following**:
1- Commonly used developing agent system
2- Commonly used solvent miscible table
3- Physical properties of commonly used organic solvents
4- Commonly used solvent polarity parameters
5- Azeotropic mixtures between commonly used solvents
6- Pressure unit conversion table
7- Acid-base concentration, azeotrope and desiccant commonly used in the laboratory
8- NMR data
9- Common chromogenic agents and configuration methods
