Abstract

Sposób zwiększenia aktywności katalizatora Ti-MWW-41 charakteryzuje się tym, że kryształy po oddzieleniu od roztworu macierzystego, suszy się i wprowadza się do 5% roztworu wodnego azotanu(V) amonu, miesza w temperaturze 60 - 90°C w czasie 6 - 12 godzin i oddziela metodą filtracji. Po oddzieleniu od roztworu, w temperaturze otoczenia przemywa mieszaniną równych objętości 30% nadtlenku wodoru i metanolu, po czym suszy w temperaturze 50 do 90°C w obecności powietrza i kalcynuje w temperaturze 520 do 550°C w czasie 24 godzin. Roztwór azotanu(V) amonu stosuje się w ilości 10 do 20 cm3 na 1 g suchych kryształów. Roztwór 30% nadtlenku wodoru i metanolu używa się w ilości 10 do 20 cm3 na 1 g mokrych kryształów.The method of increasing the activity of the Ti-MWW-41 catalyst is characterized in that the crystals, after separation from the mother liquor, are dried and introduced into a 5% aqueous solution of ammonium nitrate (V), stirred at 60 - 90 ° C for 6 - 12 hours and separated by filtration. After separation from the solution, at ambient temperature, it is washed with a mixture of equal volumes of 30% hydrogen peroxide and methanol, then dried at 50 to 90 ° C in the presence of air and calcined at 520 to 550 ° C for 24 hours. A solution of ammonium nitrate (V) is used in an amount of 10 to 20 cm3 per 1 g of dry crystals. A solution of 30% hydrogen peroxide and methanol is used in an amount of 10 to 20 cm3 per 1 g of wet crystals.
