180695-79-8 - Introduction
tert-Butyl is an organic compound with the chemical formula C13H18BrNO2.
Nature:
-Appearance: White or off-white crystalline solid.
-Melting point: about 71-73 degrees Celsius.
-Molecular weight: about 301.2g/mol.
-Solubility: Soluble in common organic solvents, such as ethanol, ether and dimethylformamide.
Use:
tert-Butyl is often used as an intermediate in organic synthesis. It can be used as an important intermediate in the synthesis of other compounds, such as drugs, dyes and natural products.
Method:
The method of preparing tert-Butyl calcium includes the following steps:
1. Dissolve N-Boc-piperidine in ether.
2. Add hydrogen bromide solution and control the reaction temperature at 0-5 degrees Celsius.
3. After the reaction is complete, saturated sodium chloride solution is added for extraction.
4. Get tert-Butyl by removing solvent and crystallizing and drying.
Safety Information:
- tert-Butyl physical and chemical properties make it dangerous. Wear appropriate personal protective equipment, such as gloves and glasses, and ensure that the operation is carried out in a well-ventilated area.
-Avoid prolonged contact with skin and inhalation of its dust to prevent irritation and allergic reactions.
-Avoid contact with strong oxidants to avoid dangerous chemical reactions.
-In the process of use and storage, follow the correct operation and safety regulations, and it is strictly prohibited to use it for illegal purposes.
