| titleOfInvention | Synthesis method and system of 1, 3-butanediol |
| abstract | The invention discloses a method and a system for synthesizing 1, 3-butanediol. The synthesis method adopts a route of producing 1, 3-butanediol from acetaldehyde via 2,6-dimethyl-1, 3-dioxane-4-ol, improves the stability of an intermediate product, improves the selectivity of the 1, 3-butanediol, and reduces the generation of harmful crotonaldehyde and derivatives which are easy to develop color and smells. Meanwhile, the tubular reactor with built-in components is used as a condensation reactor, so that heat can be effectively removed, the low-temperature cooling load is reduced, the reaction controllability is improved, unnecessary back mixing is reduced, and the generation of byproducts is reduced. The invention adopts the mode of low-temperature flash evaporation and then catalytic reaction distillation to carry out 2,6-dimethyl-1, 3-dioxane-4-alcohol cracking and recover acetaldehyde, thereby effectively improving the utilization rate of raw materials, improving the yield of final products and ensuring that the chromaticity and odor can meet the requirements of most high-end applications. |
