Its chemical properties make it a valuable component in the manufacturing of various organic compounds, such as benzoic acid and cinnamic acid. These derivatives find applications in diverse industries, including textiles, pharmaceuticals, and agrochemicals.
Benzaldehyde also has noteworthy applications in the pharmaceutical industry, particularly in the synthesis of various drugs and medications. It serves as a key precursor in the production of pharmaceutical intermediates, such as mandelic acid, which is widely used in the manufacture of antibiotics and antiseptics. Additionally, benzaldehyde derivatives play a crucial role in the development of different therapeutic agents.
⚗️ Chemical & Physical Properties
Benzaldehyde is a colorless liquid with a distinctive almond-like odor. It is commonly used in flavorings and fragrances due to its pleasant scent.
With a molar mass of 106.12 g/mol and a density of 1.041 g/cm³, Benzaldehyde is lighter than common household items like water (18.015 g/mol, 1.00 g/cm³) and sugar (342.30 g/mol, 1.59 g/cm³).
Benzaldehyde has a melting point of -26 °C and a boiling point of 179 °C. Compared to common household items like ice (0 °C) and water (100 °C), it has a higher melting and boiling point.
Benzaldehyde is slightly soluble in water and has a low viscosity. This is in contrast to common household items like salt, which is readily soluble in water, and honey, which has a high viscosity.
🏭 Production & Procurement
Benzaldehyde is typically produced through the oxidation of toluene using air in the presence of a catalyst, such as copper. This process results in the formation of benzaldehyde as the main product, along with some side products.
Benzaldehyde can be procured from chemical suppliers or manufacturers who specialize in producing aromatic chemicals. It is commonly transported in liquid form in sealed containers or drums to prevent leakage and contamination during transit.
Alternatively, benzaldehyde can also be synthesized in a laboratory setting through various methods, such as the oxidation of benzyl alcohol or the hydrolysis of benzal chloride. These methods may yield lower quantities of benzaldehyde compared to industrial production processes.
⚠️ Safety Considerations
Safety considerations for Benzaldehyde include its flammable nature, as it can easily ignite when exposed to heat, sparks, or flames. It is also harmful if swallowed, inhaled, or absorbed through the skin, causing irritation and potential allergic reactions. Proper ventilation and personal protective equipment should be used when handling Benzaldehyde to minimize the risk of exposure.
Pharmacologically, Benzaldehyde is commonly used as a flavoring agent in the food industry and as a fragrance in cosmetics and perfumes. It is also utilized in the production of dyes, pharmaceuticals, and resins. Benzaldehyde has a distinct almond-like odor and taste, which is advantageous for its use in various applications.
Hazard statements for Benzaldehyde include its classification as a flammable liquid and its toxicity if ingested, inhaled, or in contact with skin. It can cause irritation to the eyes, skin, and respiratory system, and prolonged exposure may lead to allergic reactions. Benzaldehyde may also react with oxidizing agents, acids, and strong bases, posing additional hazards.
Precautionary statements for Benzaldehyde recommend avoiding direct contact with skin, eyes, and clothing, as well as minimizing inhalation exposure by using proper ventilation. It is advised to wear appropriate personal protective equipment, such as gloves, goggles, and a respirator, when handling Benzaldehyde. In case of accidental exposure or ingestion, immediate medical attention should be sought.
