N-PHENYLPTHALAMIC ACID - Introduction
PHTHALANILLIC ACID, also known as phthalic acid benzamide, is an organic compound. Its chemical formula is C8H7NO2.
Nature:
-Appearance: White crystalline solid.
-Melting point: about 180-184 degrees Celsius.
-Solubility: insoluble in water, but soluble in organic solvents such as ethanol, ether.
Use:
- PHTHALANILLIC ACID is used as a dye intermediate and can be used to synthesize various organic dyes.
-It is also an important organic synthesis intermediate, which can be used to prepare certain pharmaceuticals.
Preparation Method:
The main preparation method of PHTHALANILLIC ACID is obtained by reacting phthalic acid with aniline. Specific steps are as follows:
1. mix phthalic acid and aniline according to molar ratio.
2. Add an appropriate amount of solvent (such as chlorinated methane) to increase the fluidity and rate of the reaction.
3. The reaction is carried out at an appropriate temperature and reaction time.
4. After the reaction, pure PHTHALANILLIC ACID was obtained by filtration, washing and drying.
Safety Information:
- PHTHALANILLIC the general nature of ACID will not cause obvious harm to the human body.
-However, safe handling measures, such as wearing protective gloves and eye protection equipment, are still required when handling the compound.
-Avoid inhaling the smell of its dust or solution, avoid contact with skin and eyes.
-Seek immediate medical help if ingested, inhaled or exposed.
