1,1-DIMETHYLUREA - Introduction
1,1-dimenthylurea, chemical formula C3H8N2O, is an organic compound. Its nature is as follows:
1. Appearance: 1,1-dimethylurea is a white solid crystal.
2. Solubility: 1,1-dimethylurea has low solubility in water and can be dissolved in alcohols and organic solvents at room temperature.
3. Stability: 1,1-dimethylurea is relatively stable, but it will react with strong oxidants and strong acids.
The main uses of 1,1-dimethylurea are as follows:
1. Catalyst: 1,1-dimethylurea can be used as a catalyst in organic synthesis reactions, such as catalytic N-alkylation and arylation reactions.
2. Solvent: Due to the good solubility of 1,1-dimenthylurea in organic solvents, it is often used as a solvent in organic synthesis.
1,1-dimenthylurea's preparation method generally has two common methods:
1. p-toluidine reacts with dimethyl carbonate to produce 1,1-dimethylurea.
2. reaction of p-toluidine and dimethyl carbonate to prepare 1,1-dimethylurea.
When using and handling 1,1-dimethylurea, you need to pay attention to the following safety information:
1. contact with strong oxidants and strong acids should be avoided to avoid dangerous reactions.
2. use to avoid inhalation of dust and skin contact, wear appropriate personal protective equipment, such as gloves and protective glasses.
3. During storage and transportation, avoid high temperature, open flame and direct sunlight.
4. if accidental contact or inhalation, should immediately clean the affected parts, and timely medical treatment.
Please note that the above information is for reference only, and the specific operation and use should be carried out according to the actual situation and relevant safety operation procedures.
