Abstract
At normal pressure, dodecyl glucoside was prepared directly by reacting dodecanol with glucose using experimental method of uniform design. Also, factors affecting yield of alkyl polyglucoside such as the amount of selfmade complex catalyzer, reaction temperature, ratio of materials and time for glocoside drying were studied. The optimum conditions obtained was as follows: ratio of catalyzer and glucose ,0.035∶1 ( m/m ); reaction temperature,120 °C ; ratio of dodecanol and glucose, 5∶1 (mol/mol); time for glucose drying, 4.5h. The yield of dodecyl glucoside was 140.1%. In addition, the surface tension and the content of glucose of the product were measured.
