colourless liquid | [Uses]
2-[2-(2-Chloroethoxy)ethoxy]ethanol is used in the preparation of ethylene glycol based amino acids. 2-[2-(2-Chloroethoxy)ethoxy]ethanol is also used in the preparation of polymers for direct and amplified DNA detection. | [Synthesis]
The reaction material in the three-necked flask was cooled to 45-50°C and 0.7 g of boron trifluoride diethyl ether compound was added as catalyst. Subsequently, 46.2 g (1.05 mol) of ethylene oxide was slowly added under stirring conditions, and the addition rate was controlled to maintain the reaction temperature at 45-55°C, using a temperature-controlled water bath for temperature adjustment if necessary. After the addition, the reaction was continued with stirring for 0.5 h to ensure complete reaction. Upon completion of the reaction, the reaction was heated and distilled under reduced pressure to collect the middle fraction at 115-123°C (vacuum 10 mmHg) to obtain a colorless transparent liquid. Further vacuum distillation was carried out under reduced pressure to collect the middle fraction at 118-121 °C (vacuum 10 mmHg) to give 123.6 g of colorless transparent liquid with 97.7% purity in the gas phase and 73.3% overall yield. | [References]
