Product Information

Introduction of P-Aminobenzoic Acid
P-Aminobenzoic acid, with the chemical formula C6H7NO2, is an organic compound. The following is a description of the substance's properties, uses, preparation and safety information:
Properties of para-aminobenzoic acid:
1. Appearance : Aminobenzoic acid is a white crystalline solid.
2. Solubility: It is relatively soluble in water and also soluble in organic solvents such as ethanol and ether.
3. CHEMICAL PROPERTIES : Aminobenzoic acid is a weak acid that can react with bases to form salts.
Uses:
1. Pharmaceutical field: Aminobenzoic acid is a commonly used ingredient in over-the-counter medicines, which is often used to treat headache, fever and arthritis and other symptoms.
2. Cosmetic field: Aminobenzoic acid can be used as a sunscreen ingredient in cosmetics, with the effect of preventing ultraviolet damage.
3. Dye and pigment industry: P-Aminobenzoic Acid belongs to one kind of Dye Intermediates, commonly used in synthetic dyestuffs and pigments, used for dyeing textiles, leathers and paint materials, etc.
Method of Preparation:
Aminobenzoic acid can be obtained by reduction reaction of p-nitrobenzoic acid. The specific preparation method includes:
1. Reacting nitrobenzoic acid with a reducing agent, such as sulfite or iron powder, etc., to obtain aminobenzoic acid under appropriate conditions.
2. Alternatively, nitrobenzoic acid is reacted with reducing metals (e.g. iron, zinc, etc.) under acidic conditions.
Safety Information:
1. Aminobenzoic acid should be avoided in contact with strong oxidizing agents and strong acids to avoid dangerous reactions.
2. Protective measures should be taken when using aminobenzoic acid, including wearing protective gloves and glasses.
3. In case of inadvertent contact with skin or eyes, flush immediately with plenty of water and seek medical assistance.
4. Aminobenzoic acid should be stored in a dry, cool place and away from fire and high temperature.

Company information

The company's main import and export products include

(1)Polymers：Polymerisation is the process by which the repeating units that make up a polymer are linked together by covalent bonds.Polymers can exist in different states depending on the phase, conformation and arrangement of their molecular chains. The two main states are amorphous and crystalline. Polymers usually exist in a semi-crystalline form in which amorphous and crystalline phases coexist.

(2)Catalysts And Auxiliaries：A catalyst is a substance that changes the rate of reaction in a chemical reaction while its own composition and quality remain unchanged after the reaction. A catalyst that speeds up a reaction is called a positive catalyst (Positive Cata-lyst), and one that slows it down is called a negative catalyst (Negative Catalyst) or retardant. Generally speaking, catalysts are positive catalysts.

Auxiliary agent refers to the industrial and agricultural production, especially in chemical production, in order to improve the production process, improve product quality and yield, or to give the product some unique application performance, usually need to add some auxiliary chemicals. It is a large class of important auxiliary raw materials in chemical production, can give the product with special properties, improve the use of finished products; can accelerate the speed of chemical reaction, improve product yield; can save raw materials, improve processing efficiency, widely used in the chemical industry.
