Process Description
2-Propyl-1-heptanol (abbreviated as 2-PH) has the chemical formula C10H22O and CAS number 10042-59-8. It is a colorless and transparent oily liquid at room temperature and pressure. It has a slight fatty alcohol smell, extremely low volatility, a boiling point of about 213°C, and a density smaller than water. Slightly soluble in water (very low solubility at 20°C, only a small amount of dispersion), miscible with most organic solvents such as ethanol, ether, acetone, aromatic hydrocarbons and oils and fats; its chemical properties are consistent with the characteristics of long-chain fatty alcohols, and can undergo esterification, oxidation, etherification and other reactions. It has good stability at room temperature, is flammable but has a high flash point (about 93°C), and is safer than short-chain alcohols. Industrially, it is mainly used in the field of chemical synthesis (as a raw material to prepare high-performance plasticizers), coatings and adhesives (as a solvent or co-solvent); it is also used in surfactant synthesis (to prepare non-ionic surfactants), plastic processing (as a plasticizer raw material), and can also be used in lubricating oil additives, cosmetic raw materials (to adjust texture) and other fields. It is especially suitable for plasticizer and solvent systems that require environmental protection, low volatility, and high performance.

Technology comment
The aldehyde hydrogenation process supporting MTO (methanol to olefins) is a new mainstream technology for the production of 2-propyl-1-heptanol. It is produced by condensation and hydrogenation of mixed butyraldehyde as a by-product of MTO. The process is green and the cost of raw materials is low. It accounts for about 60% of the total domestic production of 2-propyl-1-heptanol. This data set represents this mainstream technology: the main raw materials include low-carbon olefins and synthesis gas, which undergo low-pressure oxo synthesis reaction, aldol condensation reaction, hydrogenation, distillation and other processes:
1. The by-product C4 fraction of the MTO unit undergoes raw material pretreatment through the MTBE unit, butadiene hydrogenation unit and butene-1 unit to remove isobutylene and butadiene in the mixed C4, and the by-products MTBE and butene-1
2. Oxo synthesis: Butene-2 and synthesis gas undergo an oxo synthesis reaction under the action of a catalyst (such as cobalt or rhodium catalyst) to generate the corresponding aldehyde compounds.
3. Aldol condensation: The generated aldehyde is subjected to aldol condensation reaction in the presence of a catalyst to form a high carbon number aldehyde, namely 2-propylheptanal.
4. Hydrogenation reaction: Hydrogenate 2-propylheptanal under the action of a catalyst (such as a nickel catalyst) and convert it into the corresponding alcohol, namely 2-propyl-1-heptanol.
5. Distillation: The hydrogenated mixture is separated and purified through the distillation process to obtain high-purity 2-propyl-1-heptanol.
