CATALYST FOR OBTAINING ALKADIENES (VERSIONS) AND METHOD FOR OBTAINING ALKADIENES WITH THEREOF APPLICATION (VERSIONS) Russian patent published in 2015 - IPC B01J23/04 B01J23/06 B01J21/04 B01J21/14 C07C1/20 C07C11/167 C07C11/18 C07C11/12

Abstract RU 2571831 C1

FIELD: chemistry.

SUBSTANCE: described is catalyst for obtaining alkadienes from lower alcohols of composition, wt %: Na₂O - 0.1÷0.3, MgO - 30÷40, SiO₂ - the remaining part and another catalyst for obtaining alkadienes from lower alcohols of composition, wt %: K₂O - 0.1÷0.3, ZnO - 25÷35, γ-Al₂O₃ - the remaining part. Claimed catalysts are applied in one-stage method of obtaining alkadienes - butadiene-1,3 and isoprene by transformation of ethanol mixture with n-butanol or propanol with molar ratio of ethanol to butanol or propanol, equal (0.5÷1):1 lower alcohols at increased temperature in presence of initiator, which contains hydrogen peroxide H₂O₂ and nitrogen N₂ with molar ratio lower alcohols: H₂O₂:N₂, equal 1:(0.01÷0.02):(0.5÷1).

EFFECT: one-stage obtaining mixture of alkadienes - butadiene-1,3 and isoprene, suitable as monomers for obtaining high-quality synthetic caoutchouc, from alcohols with preservation of selectivity.
