Abstract: @ Triarylphosphates are prepared by phosphorylation of alkylphenols without use of phosphorylation catalyst. An improved phosphorylation step includes preheating alkylphenol feedstock to 150°C. and completing reaction at 215°C. or above in the presence of a stoichiometric excess of alkylphenol. The absence of phosphorylation catalyst simplifies distillative purification of reaction product by eliminating the need to withdraw purified product as distillate.

Abstract: Normally prepared alkylphenols contain little or no meta-isomer. For many purposes meta-isomers are more desirable than ortho- or para-isomers. 2,6-Dialkylphenols cause colour in phosphate esters made from alkylphenols and are undesirable. The invention reduces these problems by providing a process of isomerisation which increases the proportion of meta-isomer and decreases that of the 2,6-dialkylphenols, in which the alkylphenols are heated with trifluoromethane sulphonic acid. The alkylphenol which is isomerised may be prepared in a first step by reaction of olefin and phenol in the presence of trifluoromethane sulphonic acid. In a two stage process an alkylphenol mixture is prepared by reaction of olefin and phenol in the presence of trifluoromethane sulphonic acid at a concentration 0.01 to 5.0% at a temperature of 120°C to reflux and the mixture so produced is isomerised by maintaining the product at the same temperature to isomerise it.
Abstract translation: 通常制备的烷基酚含有很少或没有间位异构体。 对于许多目的，间位异构体比邻或对位异构体更理想。 2,6-二烷基酚在由烷基酚制成的磷酸酯中引起颜色，是不希望的。 本发明通过提供异构化方法来减少这些问题，其增加了间位异构体的比例并降低了2,6-二烷基酚的比例，其中烷基酚用三氟甲磺酸加热。 异构化的烷基酚可以在第三步中通过烯烃和苯酚在三氟甲烷磺酸的存在下反应来制备。 在两步法中，烷基酚混合物通过烯烃和苯酚在二氯甲烷磺酸存在下，在浓度为0.01至5.0％的温度在120℃至回流的条件下反应来制备，并将如此制备的混合物通过保持产物 在相同的温度下使其异构化。

Abstract: The color of alkylphenyl phosphate esters which ave developed high color due to storage in the dark is reduced by adding small quantities of phosphite ester thereto and applying heat.
