Benzaldehyde

Benzaldehyde is an organic chemical compound with the molecular formula C7H6O and CAS number 100-52-7. It is the simplest aromatic aldehyde, consisting of a benzene ring with an aldehyde functional group attached. With a molecular weight of 106.12 g/mol, benzaldehyde is classified as Acute Tox. 4 under GHS classification, indicating moderate toxicity. It is widely used in chemical synthesis and various industrial applications due to its reactive aldehyde group and pleasant almond-like fragrance.

Benzaldehyde is a colorless to pale yellow liquid at room temperature with a characteristic bitter almond odor. It has a boiling point of 179°C and is slightly soluble in water but readily soluble in organic solvents like ethanol, ether, and benzene. The compound is lighter than water with a density of approximately 1.04 g/cm³. It is sensitive to air and light, which can cause oxidation to benzoic acid over time.

Benzaldehyde serves primarily as an intermediate in chemical synthesis and as a flavoring agent. It is extensively used in the production of dyes, pharmaceuticals, and perfumes. In the food industry, it provides almond flavoring for baked goods and confectionery. Industrial applications include manufacturing of benzoic acid, benzyl alcohol, and various organic compounds. It also functions as a solvent and is used in the production of plastic additives and photographic chemicals.

Benzaldehyde requires careful handling due to its Acute Tox. 4 classification and GHS07 pictogram indicating harmful properties. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation. Avoid direct skin contact and inhalation of vapors. Handle in well-ventilated areas away from heat sources, sparks, and open flames. Keep containers tightly closed when not in use and wash hands thoroughly after handling.

Benzaldehyde should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep away from oxidizing agents, strong bases, and acids to prevent unwanted reactions. Storage temperature should be maintained below 25°C to prevent degradation. Use amber glass containers or other light-resistant packaging to minimize photochemical oxidation. Ensure storage areas are equipped with appropriate fire safety measures and spill containment systems.

Benzaldehyde exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention if breathing difficulties occur. In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and remove contact lenses if present. If ingested, do not induce vomiting and seek immediate medical attention.

Benzaldehyde disposal must comply with local and European waste regulations as it is classified as hazardous waste. Contact licensed waste disposal companies specialized in chemical waste management. Small quantities can be neutralized through controlled oxidation to benzoic acid under professional supervision. Never dispose of benzaldehyde down drains, toilets, or into soil. Use appropriate waste codes according to the European Waste Catalogue and maintain proper documentation for disposal tracking and regulatory compliance.

Benzaldehyde is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III, indicating it poses relatively low transport risk. Use UN-approved packaging suitable for liquid chemicals and ensure proper labeling with hazard identification numbers. Vehicles must carry appropriate safety equipment and documentation including transport documents and emergency instructions. Drivers require ADR certification for dangerous goods transport. Avoid transport during extreme weather conditions and ensure compliance with routing restrictions in populated areas.

Benzaldehyde is regulated under European REACH regulation and must be registered for commercial use above one tonne per year. It is classified under CLP regulation with Acute Tox. 4 classification requiring appropriate labeling and safety data sheets. However, it is not listed as a Substance of Very High Concern (SVHC). Users must comply with occupational exposure limits and workplace safety regulations. Industrial users may need to implement risk management measures and report usage under chemical safety assessments.
