CATALYSTS FOR PRODUCING ACRYLIC ACID FROM LACTIC ACID OR DERIVATIVES THEREOF IN LIQUID PHASE Russian patent published in 2020 - IPC B01J27/122 B01J27/125 B01J27/138 B01J27/16 B01J31/02 B01J31/26

Abstract RU 2715707 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a molten salt catalyst for producing acrylic acid, acrylic acid derivatives or mixtures thereof, comprising an ionic liquid (IL) and an acid; wherein said IL has a phosphonium cation and a bromide anion (Br^-); wherein said acid is soluble in said IL and selected from a group consisting of a Lewis acid, Bronsted acid and mixtures thereof; wherein said Lewis acid is selected from a group consisting of CaBr₂, MgBr₂, AlBr₃, CuBr₂ and mixtures thereof; and wherein said Bronsted acid has pK_a less than 5 in water at 25 °C.

EFFECT: high output of acrylic acid, acrylic acid derivatives or mixtures thereof.
