1,2-DIHYDROACENAPHTHYLENE-5-CARBOXYLIC ACID - Introduction

5-Acenaphthenecarboxylic acid is an organic compound with the chemical formula C12H10O2. It is a white crystalline solid with a special aromatic taste.

Nature:
5-Acenaphthenecarboxylic acid is a colorless crystal with a melting point of 146-148°C. Low solubility in water, but soluble in organic solvents such as ethanol, acetone and dichloromethane. It can be stable in the air, but will be exposed to light and yellow.

Use:
5-Acenaphthenecarboxylic acid is commonly used as an intermediate in organic synthesis and is used in the synthesis of other organic compounds. For example, it can be used to synthesize biologically active compounds, drugs and dyes.

Preparation Method:
The preparation method of 5-Acenaphthenecarboxylic acid can be obtained by reacting benzoic acid with sodium aluminum hydride (NaAlH4) in ethanol. First, benzoic acid and sodium aluminum hydride are mixed and heated in ethanol to produce benzyl alcohol and sodium aluminum acetate. Then under acidic conditions, benzyl alcohol is oxidized to produce 5-Acenaphthenecarboxylic acid.

Safety Information:
5-Acenaphthenecarboxylic acid is a relatively safe compound under normal conditions of use. However, as an organic acid, it may cause irritation to the eyes and skin, so it is necessary to pay attention to protective measures when handling, such as wearing gloves and goggles. At the same time, care should be taken to avoid inhaling its dust or contacting the oral cavity and digestive system to avoid discomfort. During handling and storage, care should be taken to prevent contact with oxidants and strong acids to avoid dangerous reactions. If discomfort is caused by accidental contact or inhalation, seek medical attention immediately.
