FIELD: gasoline production. SUBSTANCE: method, appropriate for use directly under oil-field conditions, employs either product isolated by hydrocycloning crude oil preheated to 60-90 C followed by condensation or gas condensate isolated by cooling mixture containing 85-95 vol.% of gas and 15-5 vol.% of methylal-methanol fraction from dioxan-mediated production of isoprene, containing, vol.%: methanol, 7.7; methylal, 46.35; tert-butyl alcohol, 23.73; n-butane 7.0; n-pentane, 9.13; and isopentane, 6.09. EFFECT: intensified process due to lower metal usage and reduced toxicity of gasoline combustion products.
