Abstract

The invention discloses an online-controllable-atmosphere feedback device for preparing glycolaldehyde by using synthesis gas and an application thereof, and belongs to the technical field of glycolaldehyde production. The device comprises a gas control system A, a pressurization system B, a reaction kettle system C, an analysis system D and a central processing system E. The device solves the technical problems of a conventional high pressure reaction device for preparing glycolaldehyde by using synthesis gas: 1, the raw material gas proportion is relatively fixed, the change period is long, and the raw material gas proportion cannot be adjusted targetedly according to a rhodium precursor component; 2, the reaction evaluation data analysis period is long, and adjustment and change of the raw material gas proportion of the reaction process cannot be timely fed back and guided; and 3, gas ways are frequently dismantled, potential safety hazards are increased, and the work is tedious.

Description

technical field [0001] The invention belongs to the technical field of glycolaldehyde production, and in particular relates to an on-line controllable atmosphere feedback device for producing glycolaldehyde from syngas and its application. Background technique [0002] As an important raw material for organic synthesis, glycolaldehyde is not only an intermediate of ethylene glycol, but also the smallest sugar molecule, which can react with acrolein to generate ribose, which is of great significance to the synthesis of RNA in organisms, and can also be used in pesticides , Synthesis of drugs, protein modifiers, reducing agents and antibacterial agents, etc., have very considerable market value. At present, glycolaldehyde is mainly prepared from ethylene glycol or dihydroxymaleic acid. These synthetic routes are relatively expensive and not suitable for large-scale production. Synthesis of glycolaldehyde by formaldehyde hydroformylation using low-cost paraformaldehyde and syn...
