RARECHEM AL BO 1500 - Introduction
4-Ethynylbenzoic acid is an organic compound with the chemical formula C9H6O2. The following is a description of its nature, use, preparation and safety information:
Nature:
4-Ethynylbenzoic acid is a white crystalline solid with low solubility. It appears as a colorless to pale yellow solid at room temperature.
Use:
4-Ethynylbenzoic acid is mainly used as an intermediate in organic synthesis. It can be prepared by esterification of ester compounds, as dyes, pharmaceuticals and pesticides raw materials, such as the preparation of fight cordycepic acid, anti-cancer activity. In addition, it can also be used to prepare imported and domestic dyes, such as black dye No. 138.
Preparation Method:
4-Ethynylbenzoic acid can be prepared by the reaction of phenylacetylene and benzoic acid. The specific preparation process can be divided into two steps:
1. phenylacetylene and sodium hydroxide are reacted in ether or alcohol solvent to generate 4-ethynylstyrene.
2. 4-ethynylstyrene is reacted with benzoic acid under acidic conditions to generate 4-ethynylbenzoic acid.
Safety Information:
4-Ethynylbenzoic acid has low toxicity in general. However, it can be irritating to the skin and eyes. Appropriate safety measures, such as wearing gloves and goggles, must be taken to avoid direct contact during use.
It should be emphasized that the safe use and handling details of chemicals should follow specific laboratory safety procedures and safety data sheets provided by manufacturers.
