FIELD: chemistry.
SUBSTANCE: present invention relates to a reaction system for producing butyraldehyde by carbonylation of propylene. Reaction system comprises a reactor, a propylene storage tank, a carbon monoxide storage tank, a hydrogen storage tank, propylene pipeline and synthesis gas pipeline. Reactor sidewall is provided with propylene inlet and synthesis gas inlet, note here that said inlets are arranged in said sequence from top to bottom. Inside the reactor, one above the other, there are two microsurface generators, wherein the microsurface generator located on top is connected to the propylene inlet and is designed to separate the gaseous propylene into microbubbles of micron size; and the microsurface generator located at the bottom is connected to the synthesis gas inlet and is designed to separate the synthesis gas into microbubbles of micron size. Outlets of two microsurface generators are located opposite each other, and both outlets are connected to gas distributor for uniform distribution of raw materials. Propylene inlet is connected to propylene storage tank via propylene pipeline, carbon monoxide storage tank is installed in parallel with hydrogen storage tank. Carbon monoxide storage tank and the hydrogen storage tank are connected to the synthesis gas inlet through a synthesis gas pipeline. Propylene pipeline and the synthesis gas pipeline are equipped with bubble generators for preliminary dispersion and crushing of gas into bubbles.
EFFECT: obtaining an end product with high output with a small amount of by-products using a reaction system characterized by low power consumption and high safety.
