  • Use of surfactants with high molecular weight for improving the filterability in hydraulic lubricants
    Patent number: 6624123
    Abstract: A hydraulic oil, a predominant amount of an oil having a viscosity suitable for lubrication, and from 0.03% to 0.06% of an agent improving filterability, corresponding to the formula R—Z. Z represents an ester of succinic acid comprising the reaction product of a succinic anhydride and an aliphatic polyhydric alcohol; or a succinimide comprising the reaction product of a succinic anhydride and a polyamine, the said reaction product being treated with an after-treatment agent. R represents a polyolefin having a molecular weight (Mn) of 500 to 2500 and an Mw/Mn ratio of 1 to 5.
    Type: Grant

  • USE OF SURFACTANTS WITH LOW MOLECULAR WEIGHT FOR IMPROVING THE FILTERABILITY IN HYDRAULIC LUBRICANTS
    Publication number: 20020049144
    Abstract: A hydraulic oil, a predominant amount of an oil having a viscosity suitable for lubrication and from 0.03% to 0.06% of an agent improving filterability, corresponding to the formula R—Z. Z represents a polar group containing one or more substituents chosen from phosphoric esters, amides, ethers, amino alcohols, ethoxylated amines, and mixtures thereof. R represents a lipophilic chain having 14 to 24 carbon atoms.
