| Abstract: | Esters products were synthesised through the reactions of chloroacetyl chloride with ethy-lene glycol, diethylene glycol, triethylene glycoJ and six polyethylene glycols with different average molecular weights, respectively. Index of refraction, density and surface tension of liquid products were measured and structures of the products were characterized with IR and 2H-NMR spectroscopies. For the reaction between chloroacetyl chloride and polyethylene glycol (Mn= 400), influences of reaction conditions suchas feed ratio, temperature, time and environment have been investigated. |
