A New Benchmark for High-Performance Industrial Additives! 4-Tetradecylmorpholine Empowers Industrial Upgrading Across Multiple Sectors

gainst the backdrop of the rapid-growing fine-chemical industry, high-performance specialty additives have become critical raw materials for process optimization and finished-product quality enhancement. Featuring a distinctive molecular structure, 4-Tetradecylmorpholine (CAS: 25727-93-9) combines the reactivity of the morpholine ring with the lipophilic-drophobic properties of the long-chain tetradecyl group. With stable performance, it is a high-end fine-chemical intermediate gaining increasing market recognition.

It has a high boiling point, low volatility and outstanding thermal stability, requires undemanding storage conditions, and exhibits excellent compatibility with most organic solvents. The long-chain alkyl moiety delivers superior surface-active properties, while its cyclic-amine structure endows the compound with multiple functions including neutralization, corrosion inhibition and catalysis, overcoming the application limitations of conventional amine-based additives.

Recently, 4-Tetradecylmorpholine (CAS: 25727-93-9), a fine heterocyclic intermediate, has undergone process optimization to achieve consistent supply. As a long-chain tertiary-amine product obtained via N-alkylation modification of morpholine, it has a molecular formula of C₁₈H₃₇NO and a molecular weight of 283.49. Its molecule integrates the reactive activity of the morpholine oxaza-six-membered heterocycle and the hydrophobic structure of the tetradecyl long-chain, combining heterocyclic chemical reactivity with favorable oil-solubility. It serves as a key building block for oil-field additives, mineral flotation, metal corrosion inhibition and specialty-surfactant applications.

4-Tetradecylmorpholine boasts remarkable physicochemical properties: melting point 17 °C, boiling at 170 °C under high vacuum (4 Torr), atmospheric boiling point 366.1 °C, flash point 108 °C, low vapor pressure and excellent thermal stability. Its density is 0.874 g/cm³. It is readily soluble in various organic solvents while barely soluble in water, with a high LogP value. Showing typical oil-soluble tertiary-amine characteristics, it is well-suited for formulation development in oil-phase systems. It can be further quaternized to produce long-chain morpholinium quaternary-salt derivatives for extended downstream uses such as anticorrosion, emulsification and bactericidal applications.

In industrial practice, 4-Tetradecylmorpholine is mainly applied as an intermediate for mineral-flotation collectors, an oil-phase corrosion-inhibiting component for oil-and-gas production, and a precursor for cationic surfactants. It is also widely adopted in R&D for pharmaceuticals and new-material projects. Listed in the TSCA Inventory, it meets R&D and lab-pilot production requirements across multiple industries.
