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.
