ISOFOL 2426S

DescriptionSasol Performance Chemical’s ISOFOL 2426S is a multi-branched Guerbet alcohol with unique properties. ISOFOL is the registered trademark of Sasol Germany’s 2-alkyl branched alcohols.

The ISOFOL 2426S alcohol is prepared in an Guerbet reaction using Sasol’s Fischer Tropsch based methyl-branched SAFOL 23 alcohol as starting material.

ISOFOL 2426S alcohol is characterized by a high molecular weight and, therefore increased boiling and flash point accompanied by a very low pour point.

FeaturesDue to its high molecular weight, unique branched structure and its hydroxyl function this alcohol

• exhibits a high flash and boiling point

• has a very low pour point due to Guerbet structure plus additional methyl branching

• delivers good lubricating properties

• excellent wetting ability on aluminium and cold/hot rolled steel, as well as good wetting for brass and bronze

• has good additive solvency power

• is highly stable against oxidation

• offers resistance to hydrolysis and thermally resistance under normal conditions

ApplicationsThis Guerbet alcohol can be used purely or as derivative in a wide range of applications for instance

• Raw material for metal working fluids

• Raw material for lube oil additives

• Minimum quantity lubrication

• Raw material for viscosity index improvers
