Abstract
The invention relates to an intelligent control reaction system and process for preparing butyl octanol through carbonylation of propylene. The intelligent control reaction system comprises an OXO unit, a butyraldehyde treatment unit, a butyraldehyde condensation unit, a hydrogenation reaction unit, a purification unit, a micro-interface generator and an intelligent control unit. According to theinvention, propylene and synthesis gas are treated by additionally arranging the micro-interface generator, the propylene and the synthesis gas are crushed to form micron-scale bubbles, and the micron-scale bubbles and a triphenylphosphine solution of a rhodium catalyst are mixed to form a gas-liquid emulsion, so the phase interface area of a gas phase and a liquid phase is increased, the OXO efficiency of the propylene and the synthesis gas is improved, the utilization rate of propylene is improved, and the production cost of butanol and octanol is reduced; and through the intelligent controlunit, a worker can know the real-time condition of each data returned by intelligent sensing modules at any time through mobile equipment, and can realize accurate control on the inner temperature and inner pressure of the whole reactor by changing preset values, so reaction efficiency is further improved.
Description
Technical field [0001] The present invention relates to a carbonyl method to synthesize butrtol technology, and more particularly to a intelligent control reaction system and process of octyl alcohol preparing butool alcohol. Background technique [0002] Butterol is an important raw material for synthesizing fine chemical products. At present, there is a huge amount of butter alcohol in my country, accounting for 21% of the world's total, butterol is generated by a formic acid reaction by a formic acid reaction. Further, ntisobutanol is obtained, and the two molecular n-butyldehyde condensation can also be added to an unsaturated bond to obtain octanol, and it is used to refer to butter alcohol. Typical characteristics of butanol and octanol have alcohol organic matter have a special odor, which is colorless and transparent, flammable liquid, medium toxicity, and water can form azeotrope. Mainly used in the production of plasticizers, solvents, dehydrated agents, defoamers, disp...
