Alkylation of naphthalene with n-butene catalyzed by liquid coordination complexes and its lubricating properties

High‐viscosity polyalkylphenanthrene oils: Synthesis and evaluation of lubricating properties

“…Phenanthrene alkylation with olefins is a typical Friedel‐Crafts reaction which could be easily proceeded by acidic catalysts 19–24 . Herein the acidic IL (Et 3 NHCl·2AlCl 3 ) was applied for the alkylation of phenanthrene and n ‐hexene or n ‐octene because of its own unique advantages with respect to the high activity, facile separation and mild reaction condition 25–28 …”

“…[19][20][21][22][23][24] Herein the acidic IL (Et 3 NHClÁ2AlCl 3 ) was applied for the alkylation of phenanthrene and n-hexene or n-octene because of its own unique advantages with respect to the high activity, facile separation and mild reaction condition. [25][26][27][28] Using n-hexene and n-octene as alkylation agents, four alkylphenanthrene samples were obtained by controlling the molar ratios of olefins to phenanthrene at 2:1 and 3:1, respectively, their conversions of phenanthrene closed to 100%, the corresponding alkylated products were designed as PHP-2, PHP-3, POP-2, and POP-3, their compositions were listed in Table 1. The compositions of these products were confirmed by GC-MS method (Figure S2, S3, S4), the mono-, di-, tri-, tetra-and pental-alkylphenanthrene and their isomers were observed in the final products (Table 1).…”

Decalin/Naphthalene Alkylation Using an Ionic Liquid Catalyst to Produce a Novel Base Oil and Its Tribological Properties

“…They have stable physicochemical properties that are conducive to storage and transportation. ILs exhibit unique properties such as mild reaction conditions, excellent catalytic performance, easy separation from the products, low corrosion, environment-friendliness, and reusability. , Previously, our group reported the alkylation reaction of olefins and aromatic hydrocarbons over ionic liquid catalysts, − and a variety of base oils such as alkylated naphthalene, alkylated tetralin, alkylated acenaphthene, and alkylated phenanthrene were successfully synthesized by carefully controlling synthetic conditions.…”
