This work presents the research on the influence of the addition of the appropriate amounts of the inorganic salt (Na2SO4) on the reduction of the ineffective decomposition of hydrogen peroxide (H2O2) and simultaneously on the increase of the efficiency of hydrogen peroxide conversion. The studies were carried out for the epoxidation of diallyl ether to allyl-glycidyl ether with 30 wt% hydrogen peroxide on the TS-1 catalyst and in the presence of acetonitrile as the solvent. The studies were conducted in the following conditions: the temperature of 70°C, the molar ratio of diallyl ether/hydrogen peroxide = 3:1, the acetonitrile concentration of 50 wt%, the TS-1 content of 9 wt%, the reaction time of 3 hours, the intensity of stirring of 500 rpm and the molar ratio of hydrogen peroxide/Na2SO42:1 to 14:1 (also the results for epoxidation of diallyl ether without Na2SO4were presented)

Allyl Glycidyl Ether

This paper aims to develop a modified animal glue sand binder for foundry casting with improved water resistance and bonding strength. An efficient method is reported by using sodium hydroxide as the catalyst to improve the operability of animal glue binder and allyl glycidyl ether as the modifier to improve the water resistance and bonding strength. Sand specimens prepared using allyl glycidyl ether-modified animal glue binder were cured by compressed air at room temperature. The proposed method saves energy and is environmentally friendly and inexpensive. Compared with unmodified animal glue binder, standard dog bone sand specimens with allyl glycidyl ether-modified animal glue binder had higher tensile strength of 2.58 MPa, flowability of 1.95 g, better water resistance (a lower decrease in tensile strength at 25 °C and relative humidity of 60%), and good collapsibility. This allyl glycidyl ether-modified animal glue binder is suitable for practical application in the foundry industry.
