Synthesis of an Overbased Magnesium-Containing Alkylsalycylate Additive

Synthesis of an Overbased Magnesium-Containing Alkylsalycylate Additive

Possible ways of synthesizing low-ash magnesium-containing additives for motor oils by using magnesium oxide of various origins in the synthesis have been considered: carbonation of neutral magnesium alkylsalicylate with magnesium oxide to produce a magnesium–magnesium additive and carbonation of ne...

Description
Summary:Possible ways of synthesizing low-ash magnesium-containing additives for motor oils by using magnesium oxide of various origins in the synthesis have been considered: carbonation of neutral magnesium alkylsalicylate with magnesium oxide to produce a magnesium–magnesium additive and carbonation of neutral magnesium alkylsalicylate with calcium hydroxide to form a magnesium–calcium additive. Samples were obtained with an alkalinity level of 307–317 mg KOH/g and a viscosity not exceeding 130 mm 2 /s, values that meet the requirements for alkylsalicylate additives.
