Quality:
- Appearance: Resorcinol is a white to pale yellow crystalline solid.
- Solubility: Resorcinol is soluble in water, ethanol and ether solvents.
Use:
- Preservatives: Resorcinol has good antibacterial properties and can be used as a preservative, often used in wood, paper, paint and other antiseptic treatments.
- Synthetic dye intermediates: They contain multiple hydroxyl groups in their structure and can be used to synthesize intermediates of organic compounds such as dyes and fragrances.
- Other applications: Resorcinol can also be used as a preservative and antioxidant in materials such as synthetic resins, rubber, and plastics.
Method:
Resorcinol can be prepared in a variety of ways, and one commonly used method is to obtain it by reacting phenol and hydrazine hydrate under acidic conditions.
Safety Information:
- Phloroglucinol is toxic to the human body, and excessive exposure or inhalation may cause irritation to the skin, eyes, and respiratory system.
- Care should be taken to prevent contact with strong oxidants and strong acids during handling and storage to avoid dangerous chemical reactions.
- Personal protective equipment such as gloves, goggles, and face shields should be worn properly when using resorcinol and avoid direct contact or inhalation.
- Follow proper handling and disposal practices to reduce pollution to the environment.
