CATALYST AND METHOD OF ALKYLATING ETHANOL WITH ISOPROPANOL Russian patent published in 2016 - IPC B01J23/89 C07C31/125 C07C29/32 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst and a method of alkylating ethanol with isopropanol to produce pentanol-2. Catalyst for alkylation of ethanol with isopropanol consists of γ-Al₂O₃, Cu or Ni and a second metal - Au in following proportions, wt%: Au - 0.2-0.5, Ni or Cu - 0.06-0.32, γ-Al₂O₃ - balance. Method of alkylating ethanol with isopropanol is carried out in an autoclave-type reactor in presence of said catalyst at partial pressure of ethanol and isopropanol of 61-100 atm, temperature of 240-295 °C for 1-8 hours while stirring constantly.

EFFECT: high selectivity of formation of end product - pentanol-2 - with high degree of conversion of initial alcohols, higher efficiency on target component, reduced time of contact.
