| Abstract: | It has been found that heteropolyacid salts such as silver phosphotungstate(Ag 3PW 12 O 40 )and silver silicotungstate (Ag 3SiW 12 O 40 )have high catalytic activity and stability for the synthesis of diethyleneglycol ethyl ether from diethylene glycol and ethanol.The yields of mono and di ethyl ether are 65.3% and 70.4% respectively,and the total yields of mono and di ether after reaction for the third time are 60.5% and 63.4% respectively.The catalytic performance of heteropolyacid salts is found to be relevant to the particular nature of different acid centers as revealed by the results of IR,XRD,TG and n butylamine surface acidity tests. |
