二对甲苯磺酸三乙二醇酯 - Introduction
Tritium (ETHYLENE GLYCOL) DI-P-TOLUENESULFONATE, also known as TEPMT, is an organic compound. The following is an introduction to the nature, use, preparation and safety information of TEPMT:
Nature:
-Appearance: TEPMT is a colorless or pale yellow liquid.
-Solubility: Soluble in organic solvents such as ethanol, acetone, dichloromethane.
-Melting point and boiling point: The melting point is about -30°C, and the boiling point is about 200°C.
-Chemical properties: TEPMT has good thermal stability and chemical resistance.
Use:
TEPMT has many applications in organic synthesis:
-Catalyst: used as an additive for metal catalysts to promote chemical reactions.
-Protecting group: Due to its stability, it can be used as a side reaction suppressor for protecting active groups.
-Functional materials: It can be used to synthesize liquid crystals, polymers and organic electronic materials to improve performance and stability.
Method:
The preparation of TEPMT usually uses the following steps:
1. Mix toluene sulfonic acid with triethylene glycol.
2. Add an appropriate amount of acid catalyst at an appropriate temperature.
3. The reaction is continued until the desired product is formed.
4. Separate the product, after purification and purification steps, pure TEPMT product is obtained.
Security Information:
- TEPMT is generally considered harmful and direct contact with skin and eyes should be avoided.
-Wear appropriate personal protective equipment such as gloves, protective glasses and laboratory coats during use and handling.
-It should be operated in a well-ventilated place to ensure that the gas or vapor generated is not inhaled.
-During storage and transportation, TEPMT should be stored in a dark, dry, cool place, and away from high temperature and open flame.
Please note that the above information is for reference only. If you plan to use or handle TEPMT, please refer to the safety data sheet and operating guide of the relevant product, and strictly abide by the relevant laboratory operating procedures and safety measures.
