From recent literature

Pour depressants for waxy lubricat­ing oils are prepared by treating an aliphatic substituted hydroxy aro­matic compound of formula RnArOH with an acylating agent (i.e. sebacic acid chloride) in the presence of a Friedel-Craft catalyst. R is prefer­ably an alkyl group of less than 12 carbon atoms and η is 1 or 2. Two percent of the alkyl phenol deriva­tive depresses pour point of waxy oil from 30° F. t o - 5 ° F .

Trialkyl phenyl phosphates of im­proved charac te r i s t ics have been prepared by reacting alkyl phenols obtained from petroleum with phos­phorus oxychloride at a temperature of140°C.

Such products have greater elec­trical resistance, higher viscosities, lower toxicities and lower density than phosphoric acid esters made from other alkyl phenols.

Heavy metal salts of alkyl phenol sulfides have been prepared and are found useful as Diesel crank case lubricant additives. They are partic­ularly effective in inhibiting oxida­tion and the formation of gums.

Resinous condensation products may be made by causing acetylene to react at a t empera tu re be tween 150° C. and 300° C , and at super-atmospheric pressures with alkyl phenols having secondary or tertiary alkyl groups containing 3 to 12 car­bon atoms. A strongly alkaline cata­lyst is required.

These developments are abstracted from recent publications or U. S. patents. The uses may suggest other applications of Jefferson Alkyl Phenol C-9 in your products or processes.
