⚗️ Chemical & Physical Properties
Benzoic anhydride is a white crystalline solid with a pungent odor. It is commonly used in the synthesis of pharmaceuticals and as a reagent in organic chemistry reactions.
With a molar mass of 138.11 g/mol and a density of 1.198 g/cm³, benzoic anhydride is heavier than common food items such as sugar (sucrose) with a molar mass of 342.3 g/mol and a density of 1.587 g/cm³. This higher molar mass and density contribute to its solid state at room temperature.
Benzoic anhydride has a melting point of 42.5°C and a boiling point of 288.4°C. In comparison to common food items like salt (sodium chloride) with a melting point of 801°C and a boiling point of 1413°C, benzoic anhydride exhibits lower melting and boiling points due to its molecular structure.
Benzoic anhydride has limited solubility in water and is viscous in nature. This contrasts with common food items like sugar, which is highly soluble in water, and vinegar, which has a low viscosity. These differences in solubility and viscosity are due to the unique chemical structure of benzoic anhydride.
🏭 Production & Procurement
Benzoic anhydride, also known as benzenecarboxylic anhydride, is primarily produced through the oxidation of benzoic acid. This process typically involves the reaction of benzoic acid with acetic anhydride in the presence of a catalyst, such as sulfuric acid. The resulting product is then purified through processes such as distillation or recrystallization to obtain pure benzoic anhydride.
In terms of procurement and transportation, benzoic anhydride is commonly available for purchase from chemical suppliers and manufacturers. It is typically packaged and transported in sealed containers, such as drums or bags, to prevent contamination or exposure to moisture. Due to its potential reactivity with air and moisture, benzoic anhydride should be stored in a cool, dry place away from sources of heat and open flames to ensure its stability and shelf life.
When handling and using benzoic anhydride, proper safety precautions should be observed, including the use of personal protective equipment such as gloves, goggles, and lab coats. In the event of accidental exposure or spillage, it is important to seek immediate medical attention and follow appropriate procedures for cleanup and disposal. Overall, the production and procurement of benzoic anhydride require careful attention to detail and adherence to safety guidelines to ensure its efficient and safe use in various industrial applications.
⚠️ Safety Considerations
Safety considerations for Benzoic anhydride involve handling the substance with care to prevent any direct contact with skin, eyes, or mucous membranes. It is important to wear appropriate personal protective equipment, such as goggles, gloves, and a lab coat when working with Benzoic anhydride. Additionally, the substance should be stored in a tightly closed container away from sources of ignition and incompatible materials to prevent any potential hazards.
Hazard statements for Benzoic anhydride include “Causes severe skin burns and eye damage” as well as “May cause respiratory irritation.” These statements highlight the potential dangers of direct contact with the substance, emphasizing the need for proper safety precautions when handling Benzoic anhydride. It is important to take these hazards seriously and follow all recommended safety measures to avoid any negative effects on health.
Precautionary statements for Benzoic anhydride include “Wear protective gloves/protective clothing/eye protection/face protection” and “IF ON SKIN (or hair): Take off immediately all contaminated clothing.” These statements provide clear guidance on how to safely handle the substance and what steps to take in case of accidental exposure. By following these precautionary measures, the risk of harm from Benzoic anhydride can be minimized, ensuring a safe working environment for all individuals involved in its handling.
