FIELD: technology of petroleum chemistry, organic chemistry.
SUBSTANCE: invention relates to a method for preparing isoprene, isobutylene and formaldehyde from by-side products in the process for producing isoprene. Methyldihydropyrane and/or high-boiling products are heated in the presence of steam up to temperature 400-550°C followed by their contacting with alumosilicate-containing catalyst in the presence of steam at temperature 400-480°C. Method provides enhancing the selectivity of process, to enhance the conversion of heavy residue and to reduce the coke deposition. Invention can be used in industry of synthetic rubber and the organic synthesis.
EFFECT: improved processing method.
