Method for production of alkyl-tert-butyl ethers and method for simultaneous production of such ethers and 1-butene |
| abstract |
FIELD: organic chemistry. SUBSTANCE: simultaneous production of alkyl-tert-butyl ethers and 1-butene involves feeding of stream of C 4 hydrocarbons into etherification block, recycling or residual stream into the same block after practicable separation of 1-butene and conversion of residual butenes into isobutene which takes place in isomerization block. Block of separation of hydrocarbons in steam phase with the help of molecular sieve is included into cycle. EFFECT: improved efficiency of the method. 18 cl, 4 tbl, 5 dwg |
