   Mesoporous molecular sieves containing aluminum ions (Al-MCM-41) with Si/Al ratio equal to 30 were used to supported calcium borate (CaB4O7) by microwave irradiation method. The CaB4O7/ Al-MCM-41 (CBA1M) were used in the Ethoxylation as catalysts .The results show that CBAlM has higher catalytic activity than Al-MCM-41 and CaB4O7. The reaction is carried out at 120℃in the presence of 5% catalyst in relation to the octanol. The homologue distributions of ethoxylates were determined by GC and HPLC measurements and that showed the homologue distributions of octanolpolyoxyethylene ether were narrowed using the CBA1M catalyst for alcohols ethoxylation.……
