• Product Uses:
  • Mainly used in the production of plasticizers: It can react with polybasic acids and acid anhydrides such as phthalic anhydride, trimellitic anhydride, and adipic acid to synthesize various ester - type plasticizers. Among them, the reaction with phthalic anhydride to synthesize di(2 - propylheptyl) phthalate (DPHP) is more common. PVC products plasticized with DPHP have better electrical insulation, weather resistance, low volatility, and low - fogging properties, and are more environmentally friendly than the traditional dioctyl phthalate (DOP).
  • Production of alkoxylated surfactants: It can react with ethylene oxide to produce alkoxylated surfactants, which can be used as the active components of synthetic detergents.
  • Preparation of adhesives: Its acrylate is a kind of acrylic ester for adhesives with excellent performance. The polymer adhesive prepared from 2 - propylheptyl acrylate is a good adhesive for steel structures.
• Production Method: Industrial production mainly adopts the low - pressure carbonylation synthesis technology. The 1 - butene and 2 - butene in the mixed C4 olefins can be converted into n - valeraldehyde under the action of a rhodium catalyst. Two molecules of n - valeraldehyde are condensed to obtain decenal, which is then hydrogenated into 2 - propylheptanol under the action of a nickel catalyst.
• Production Distribution: The production is mainly concentrated in Germany and the United States. BASF in Germany and the Dow - Davy joint company in the United States own the relevant production technologies. With the development of coal - to - olefins projects in China, in 2010, the first set of 2 - propylheptanol production device using coal - based mixed C4 as raw material was built in Shenhua Baotou. There are also many coal - to - olefins enterprises planning to support related projects.
• Product Grade and Content: There are premium - grade products in the market, with a content of ≥80%, and there are also products with a purity of ≥98% for biochemical analysis and other fields.
