Abstract: FIELD: industrial organic synthesis. 
     SUBSTANCE: first stage of the process comprises synthesis of 4,4-dimethyl-1,3-dioxan via isobutylene/formaldehyde condensation in presence of acid catalyst at 80-100ºC and pressure 1.6-2.0 MPa. Product and high-boiling by-product mixture are isolated from oil layer of reaction mixture. 4,4-Dimethyl-1,3-dioxan is then decomposed on calcium phosphate catalyst at 290-380°C and pressure 0.12-0.16 MPa in presence of water steam. Contact gas is further processed to produce isoprene. High-boiling by-product mixture is distilled on two in series connected vacuum rectification columns. On the first column, 60-70% of distillate is recovered based on the weight of feed. Second distillation on the second column gives second distillate (75-90%) and bottom product, which is recycled into 4,4-dimethyl-1,3-dioxan synthesis zone. Second-column distillate is decomposed into isoprene on ceramic filling at 400-450°C and pressure 0.12-0.16 MPa in presence of water steam supplied at (2-5):1 weight ratio to high-boiling by-product mixture. Contact gas obtained after decomposition of this mixture is processed jointly with contact gas obtained after decomposition of dimethyldioxan. 
     EFFECT: reduced amount of process waste and increased production of isoprene without increase in consumed raw material.

Abstract: FIELD: alcohol production industry. 
     SUBSTANCE: Alcohol is first extracted by boiling from brew on the brew column while transferring ethyl alcohol with accompanied impurities into brew distillate together with vapor leaving the column. Brew distillate is freed of top and intermediate impurities, including fusel oil components, on epuration column while supplying hot water onto upper plate. Epurate is rectified on alcohol column wherein fractions of fusel oil, fusel alcohol, and non-pasteurized alcohol are recovered. Fractions of top and intermediate impurities of ethyl alcohol are distilled on distillation columns. Ethyl alcohol is further purified in distillation sections of epuration and distillation columns by way of removing fusel oil fractions from vapor phase of plates in their mediate zones, whereas organic acids and other tail impurities are withdrawn with distillation water from epuration and distillation column bottoms. Epurate is concentrated, withdrawn from liquid phase of lower plates of boiling-extraction section of epuration column and passed to feeding plate of rectification column. Ethyl alcohol fraction is withdrawn from liquid phase of lower plates of extraction-distillation section of distillation column and passed to feeding plate of epuration column. Fractions from condensers of rectification and methanol columns and from alcohol-trap for pure distillates are passed to feeding plate of additional column, from the condenser of which top impurities concentrate is discharged. Bottom liquid is supplied to feeding plate of rectification column.
