Reaction Steps

n-butyl 3,4-dimethylcyclohexyl 2,6-di-t-butyl-4-methylphenyl borate was prepared by successively transesterifying tri-n-butyl borate with 2,6-di-t-butyl-4-methylphenol and 3,4-dimethylcyclohexanol. Tri-n-butyl borate (1 mole) and 2,6-di-t-butyl-4-methylphenol (1 mole) were heated, with stirring, to a temperature of 280° C. and n-butanol collected as a distillate. After seven hours 0.81 moles had been collected and a total of 0.82 moles collected after ten hours. After cooling the reaction vessel and adding 1 mole of 3,4-dimethylcyclohexanol, the reaction mixture was again heated to 280° C. for six hours, after which time a further 0.9 moles of n-butanol had been collected. Volatile components were then removed under reduced pressure (90° C./0.1 mm) to leave a viscous golden yellow liquid as product.
