Abstract
A zinc dialkyl dithiophosphate product particularly adapted for use as an improvement agent for lubricating oils is obtained by reacting phosphorus pentasulphide in a molar ratio of substantially 1 to 4 with an alcohol ROH wherein R is a higher alkyl radical of 6 to 18 carbon atoms at elevated temperature to form a reaction product containing a dialkyl dithiophosphoric acid, treating the reaction product with an alcohol having the formula R1OH wherein R1 is a lower alkyl radical having up to 4 carbon atoms at about 170 DEG F. to about 200 DEG F. for from about 1/2 to about 2 1/2 hours, neutralizing the product with a compound containing zinc to form a reaction product containing the zinc dialkyl dithiophosphate and ageing said reaction product by subjecting it to a temperature within the range of from about 140 DEG F. to 195 DEG F. for from about 1/2 to 6 hours. Specified higher alcohols are 4-methyl-2-pentanol (methylisobutylcarbinol), n-hexanol, n-octanol, iso-octanol, dodecanol, hexadecanol and octadecanol and specified lower alkanols are methanol, ethanol, propanol, isopropanol and butanol. The amount of lower alkanol may be from about 5 to 25% of the weight of the higher alkanol originally reacted with the phosphorus pentasulphide. The neutralization with the zinc compound may be effected by adding up to 150% of the theoretical excess of a zinc compound such as zinc oxide or hydroxide until a hydrogen sulphide test is negative. The neutralized, aged product may be blended with other additives such as silicone oil anti-foam agents, detergents such as sodium or barium petroleum sulphonate, dropped to a still, stripped, and then filtered. A blending oil (hydrocarbon lubricating oil) may be added before or during the neutralization or after the stripping or filtering to bring the concentration of the additive to a desired range. In the examples given, methyl isobutyl carbinol is used as the higher alkanol and ethanol, isopropanol and n-butanol respectively as the lower alkanol.
