HIGH-OCTANE OXYGEN-CONTAINING COMPONENT Russian patent published in 1999 - IPC

FIELD: chemical industry. SUBSTANCE: high-octane oxygen-containing motor fuel component comprises C₅, hydrocarbons, methyl-tert- amyl ether and C₁₀, hydrocarbons and it further comprises methyl-sec-amylene ether, tert-amyl alcohol and isoprene ethers resulting from production of alkyl-tert-alkyl ethers. C₅ hydrocarbons includes mixture of unreacted C₅ hydrocarbons during isolation of isoprene from C₅ pyrolysis hydrocarbons and during two-stage dehydrogenation of isopentane to isoprene, and C₁₀ hydrocarbons includes mixture of isoprene and pentadiene- 1,3 dimers, ratio of components being as follows, wt. %: mixture of unreacted C₅ hydrocarbons, 0.1-10.0; methyl- tert-amyl ether, 2.0-50.0; methyl-sec-amylene ether, 40.0-95.0; isoprene ethers 0.1-5.0; tert-amyl alcohol, 0.05-5.0; C₁₀ hydrocarbons, 0.05-5.0. EFFECT: simplified and cheaper process. 2 cl, 1 dwg, 6 ex, 1 tbl
