FIELD: petroleum processing and petrochemistry.
SUBSTANCE: antiknock additive contains 25-45% anhydrous isopropyl alcohol, up to 50% isopentane fraction, and balancing amount of propylene-based isopropyl alcohol production by-products.
EFFECT: increased production of A-76 and AI-92 gasolines having high antiknock characteristics without substantial advance of price.
