Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. Butanol is widely used in fields such as chemical synthesis, solvents, pharmaceutical synthesis, fragrances and food, the preparation of butanol gasoline, and detergents. Butanol is modelled as a pure substance; when modelling this substance the user needs to add a solvent of their choice in the model; the dataset contains the main raw and auxiliary materials, energy, waste and atmospheric emissions of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include propylene hydroformylation reaction, butyraldehyde purification, hydrogenation reaction and butanol refining.
Activity Description
The production activities of this product include propylene hydroformylation reaction, butyraldehyde purification, hydrogenation reaction, butanol refining and other processes.
Process Description
The chemical formula of butanol is C4H10O, CAS number 71-36-3. It is a colorless and transparent liquid under normal temperature and pressure. It has a special alcoholic aroma and is easy to volatilize. Its boiling point is about 117.7°C and its density is slightly smaller than water. Slightly soluble in water, miscible with most organic solvents such as ethanol, ether, acetone, etc.; its chemical properties have the typical characteristics of alcohols, and can undergo esterification, oxidation, dehydration and other reactions. It has good stability at room temperature and is flammable. Steam and air can form explosive mixtures. It is mainly used in chemical synthesis and solvent applications in industry (as a solvent for coatings, inks, and adhesives, especially suitable for dissolving resins and rubbers); it is also used in the pharmaceutical industry (preparing pharmaceutical intermediates, antibiotics and other drugs), spices and food industries (synthesizing spice ingredients, or as a solvent for food additives). It can also be used to prepare butanol gasoline (fuel additive), detergent raw materials, and as a commonly used organic solvent in laboratories.

Technology comment
The low-pressure propylene oxo synthesis method is an advanced mainstream technology for butanol production. It is produced through the oxo synthesis reaction of propylene and synthesis gas under low pressure. The process is gentle and highly selective. It accounts for more than 90% of the domestic butanol market. This data set represents the mainstream technology: using the oxo synthesis method, that is, the REPPE method, using propylene, synthesis gas and hydrogen as the main raw materials, and synthesizing butanol under the action of a catalyst:
1. Propylene hydroformylation reaction: First, propylene and synthesis gas undergo a hydroformylation reaction under the action of a catalyst to generate crude aldehyde.
2. Separation and purification of butyraldehyde: Through the refining process, n-butyraldehyde and isobutyraldehyde are separated from the crude aldehyde.
3. Hydrogenation reaction: n-butyraldehyde and isobutyraldehyde are subsequently converted into crude butanol through hydrogenation reaction.
4. Butanol refining: Impurities are removed from crude butanol in a multi-tower distillation system.
