Abstract

The present invention relates to mixtures containing calixarenes of formula (I) with a reduced alkyl phenol and linear oligomer content and the preparation process thereof, wherein: a. R is selected between a linear or branched alkyl having a number of carbon atoms comprised between 4 and 40, more preferably between 4 and 24, even more preferably comprised between 8 and 18; b. n is the number of units of the calixarene cycle and is comprised in the range from 4 to 16, preferably between 4 and 12. Furthermore, the present invention relates to detergent compositions containing overbased metal salts of calixarenes, the preparation process thereof and the use thereof in lubricant compositions.
Mixture containing calixarenes, process for the production thereof and use thereof for preparing detergent compositions for lubricants / Notari, Marcello; Assanelli, Giulio; Casnati, Alessandro; Sansone, Francesco; Magini, Andrea. - (2020).
