It was found that the presence of water in the reaction mixture, compared with the use of rectified ethanol, leads to a decrease in ethanol conversion and selectivity/yield of the 1,3-butadiene. This is due to the blocking of part of the seats of aldol condensation of acetaldehyde. It was found that the modification of Zn(Cu)ZrSi metal oxide systems by lanthanum compounds increases the selectivity for the 1,3-butadiene in the presence of water in the reaction mixture. The possibility of obtaining reactivity liquid rubbers by radical polymerization of diene in the presence of acetaldehyde in the raw material is shown.
