    摘要： The invention is directed to the increasing of selectiveness of the process (UYUP), increasing of conversion of raw materials and heavy residue, and also the depth of processing.
    The indicated technical result is achieved by that way, that the method of processing of co-products of liquid-phase synthesis of isoprene from formaldehyde or formaldehyde-containing products is carried out at the temperature of 400-480°C in the presence of the water vapor with the aluminum silicate-containing catalyst with the further heating up to the temperature of 400-550°C, in this case, the process is carried out at the initial temperature, that is 5-40°C lower and the final temperature, that is 5-40°C higher, than the average temperature of contacting during the progressive increasing of the temperature from the initial au to the final one and during the constant reducing of the feed space velocity at the beginning of contacting 3-15 % higher, and at the end of contacting 3-15 % lower, than the middling cycling feed space velocity (table 4).
