苄基-PEG8-羟基 - Introduction

Octaethylene glycol Monobenzyl ether, chemical formula C23H30O8, is an organic compound. The following is a description of its nature, use, preparation and safety information:

Nature:
Octaethylene glycol Monobenzyl ether is a colorless to yellow liquid with a special aromatic odor. It has a density of about 1.17 g/mL, a melting point of 26-30 ° C., and a boiling point of 410-420 ° C. The compound is relatively stable at ambient temperature and soluble in organic solvents such as ethanol, dimethylformamide and dichloromethane.

Use:
Octaethylene glycol Monobenzyl ether is commonly used as a solvent and catalyst, and has a wide range of applications in organic synthesis. It can be used for esterification, etherification, condensation and alkylation reactions in organic synthesis reactions. In addition, it can also be used as an additive for plastics, rubber and dyes, as well as in the pharmaceutical field.

Method:
The preparation of Octaethylene glycol Monobenzyl ether is generally carried out by etherification. First, octaethylene glycol and benzyl alcohol are reacted under an alkaline condition, and an alkaline catalyst such as sodium hydroxide is commonly used. The reaction conditions are usually carried out at high temperature, and the resulting etherification products are dehydrated to give Octaethylene glycol Monobenzyl ether.

Safety Information:
Octaethylene glycol Monobenzyl ether is a chemical with certain potential hazards. During handling, care should be taken to prevent contact with skin and eyes. As with other organic solvents, they should be used in a well-ventilated area and avoid breathing their vapors. During storage and transportation, keep away from fire and oxidant, and keep the container sealed to prevent leakage. In actual operation, relevant safety operating procedures should be followed and appropriate personal protective equipment should be provided, such as protective gloves, safety glasses and protective masks.
