Introduction
Salicylaldehyde is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of salicylaldehyde:
Quality:
- Appearance: Salicylaldehyde is a colorless to yellowish liquid with a special bitter almond aroma.
- Solubility: Salicylaldehyde has a high solubility in water and is also soluble in most organic solvents.
Use:
- Flavors and flavors: Salicylaldehyde has a unique bitter almond aroma and is commonly used in perfumes, soaps and tobacco as one of the components of fragrance.
Method:
- In general, salicylaldehyde can be produced from salicylic acid through redox reactions. The most commonly used oxidant is acidic potassium permanganate solution.
- Another preparation method is to obtain salicylyl alcohol ester by chlorination ester of phenol and chloroform catalyzed by hydrochloric acid, and then to obtain salicylaldehyde by hydrolysis reaction catalyzed by acid.
Safety Information:
- Salicylaldehyde is a harsh chemical and should be avoided from direct contact with the skin and eyes.
- When using or handling salicylaldehyde, maintain good ventilation conditions and avoid inhalation of its vapors.
- When storing salicylaldehyde, it should be kept in an airtight container, away from ignition and oxidants.
- If salicylaldehyde is ingested or inhaled by mistake, seek medical assistance immediately.
