Sammanfattning

For the first time, the new microwave-assisted method for the synthesis of copper phyllo-silicates on a commercial SiO2 carrier was developed. The application of microwave synthesis al-lowed to decrease the synthesis time from 9 to 6 h compared to the traditional DPU method of preparing chrysocolla. The synthesized catalysts were studied by N2 adsorption, TEM and XRD methods. Catalysts prepared by microwave method are highly effective in the selective hydrogenation of the С≡С bond in 1,4-butynediol to 1,4-butenediol and 2-phenylethinylaniline with a selectiv-ity of 96.5% and 100% at full conversion for 2 and 0.5 h of the reaction, respectively.
