Di-p-tolylcarbodiimide - Introduction
di-p-tolylcarbodiimide (di-p-tolylcarbodiimide) is an organic compound with the chemical formula C16H14N2 and the CAS number 538-75-0.
Its properties include:
-Appearance: Colorless crystalline solid
-Melting point: 162-164°C
-Boiling point: 360°C (decomposition)
-Density: 1.10g/cm³
di-p-tolylcarbodiimide has a wide range of applications in organic synthesis, mainly for the following aspects:
-Used as a chemical reagent: as a catalyst for the condensation reaction of aromatic amines and aldehydes, thereby forming imines. In addition, it can also be used for the synthesis of urea and cyanate esters.
-For protein chemical modification: It can be used to modify proteins, such as introducing fluorescent labels or other functional groups.
-Used in organic electronic devices: It can be used to prepare organic light-emitting diodes (OLED), organic solar cells (OPV), etc.
The preparation method of di-p-tolylcarbodiimide is generally by introducing di-p-methylaniline (p-dimethylaniline) and carbodiimide for reaction. The specific method can be:
1. dissolving di-p-methylaniline in an organic solvent;
2. add carbodiimide and react for a certain time;
3. Filter the product to give the di-p-tolylcarbodiimide.
Regarding safety information, di-p-tolylcarbodiimide may irritate the skin and eyes under certain conditions, and cause damage to the respiratory tract. Therefore, in use should pay attention to the following matters:
-Avoid direct contact with skin and eyes to prevent inhalation of its dust.
-It is necessary to operate in a well-ventilated area and wear appropriate personal protective equipment, such as safety glasses, protective gloves and dust mask.
-In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
-Avoid contact with oxidants and acids during storage to prevent dangerous reactions.
In general, di-p-tolylcarbodiimide can exert its catalytic and modifying properties under suitable conditions, but it is necessary to pay attention to safe operation during use.
