Benzoat Acid Consciousness, Other Names, Adnature and Example
Benzoat acid It's one of the simple aromatic compounds that matter in organic chemistry, whether it's from the side of molecular structure, reactivity, or its applications in various industries. It talks deeply about the understanding of benzoic acid, synonym or any other name used in scientific literature and industry, the physical properties of its own possession, and some examples of its use, based on literature studies and experimental data from various trusted scientific sources.
Benzoat Acid Understanding
Benzoate acid is an organic compound with chemical formula. C-H-COOH. Structurally, this compound consists of a benzene ring bound to a carboxic (-COOH) cluster, making it as acid aromatic monocarboksilate. Benzoate acid is a member of a simple carbochilate acid class and many are found naturally in plants and animals.
Historically, benzoat acid was first isolated in the 16th century from benzine gum, which is the aromatic sap of a tree. Styrax Shh. The name "benzoat" comes from that natural material. As the growth of modern organic synthesis, the acid of benzoate is now produced industrial through the oxidation of toluena using the metal catalyst.
_
In various fields and literature, benzoat acid is known as several other names, among other things:
- Fenilformat acid
- Carbochibenzene acid.
- E210 (as food additive code in international notation system)
- Benzencarboksilat (in IUPAC nomenclature)
This synonym is often used depending on the context of its use, as in pharmaceutical, food industry, or theoretical chemistry.
Physical and acidic properties of Benzoat Acid
1. Physical properties
- The molecular formula: ♪
- Molar mass: 122.12 g / mol
- Bow: Solid white chrystalin
- Melted Point: 122 ° C
- Boiling point: 249 ° C (with partial decomposition)
- It's in the water: 3.4 g / L at 25 ° C (low)
- The high-quality awkwardness of ethanol, ether, and other organic solvent.
2. Chemical nature
- Benzoate acid is a weak acid with pKa around 4.2, so that only partly ionized in water solution.
- In the base state, the benzoat acids form salt benzoat, like sodium benzoat.
- It can have an aromatic substitution reaction (for example, nitrate, sulfonation) in an orto-para position.
- Can experience decarbochilation at high temperatures into benzene and karbon dioksida, a reaction relevant in another aromatic compound synthesis.
Benzoat Acid Production (Industrial Scale)
Commercially, benzoat acid is produced in a way toluena catalytic oxidation in liquid phases using air or molecular oxygen as oxidizing and coalted-based catalyst or mangan. This reaction can summarize as follows:
Come on.
This reaction has a high rendering and is widely used in industry chemical material basic due to efficiency of process and low production costs.
Benzoat Acid Usage Example
1. Food Industries
The acid benzoate and its derivative (mainly sodium benzoat) used as Food preservatives Code E210 to E213. This compound is active against microorganisms like yeast and bacteria in low pH conditions. Used in products like:
- Soft drink
- Fruit juice
- Sauce and vinegar
- Margarin
2. Pharmaceutical Industries
Benzoate acid is used as active material or exipien in:
- Salts and antifungal cream
- Exspectoran medicine.
- Topic antiseptic
3. Organic Senyawa Synthesis
The benzoate acid is an important precursor in the thesis of the benzoate, benzoat benzoat, and other intermediate compounds used in the perfume industry, plasticizer (e.g. plasticizer), and synthetic dye.
Four. Plastic Industries and Resin
The derivative of benzoic acid, such as benzoil chloride and anhidrida benzoat, is used in production. resin alkid, polyester, and plasticizer to increase product flexibility.
Risk and Security
Based on the evaluation of Food and Drug Administration (FDA) And other regulatory bodies, benzoate acid is safe when used within designated limits. However, excessive consumption or use in certain conditions can result in side effects, such as:
- Skin irritation and respiratory tract if inhaled as fine powder
- Formation benzene (carcinogen) if it reacts to ascorbat acid (vitamin C) under certain conditions
Therefore, strict regulation applied to its use, including maximum residue limits in food products (generally < 0.1%).
Supporter Experimental Data
In publication by J. Agric., said that benzoic acid is naturally detected in fruits such as cranberries, plums, and apples with varied concentration of 0.05-0.5 mg / g. The study uses a high-performance liquid chromatography (HPLC) to authenticate, indicating that although natural, benzoat acid must still be controlled by its exact use in food formulation.
Conclusion
Benzoate acid is an important aromatic organic compound that has a crucial role in the food industry, pharmaceutical and chemistry. With the nature of the weak acid, the thermal stability is good, and the ability to form salts that dissolve water, benzoic acid becomes the primary option as preservative and chemical precursor. The profound understanding of the chemistry and its applications is important not only to academics, but also to the industrial offenders who implement them on a massive scale.
As researchers and chemical practitioners, we are charged not only to understand the molecular structure and its reactiveness, but also to note the toxicology and environmental impact of this compound, especially if used in large and long-term quantities.
