Pentaerythritol Tetra(3-mercaptopropionate) Usage And Synthesis

Description

Pentaerythritol Tetra(3-mercaptopropionate), also known as pentaerythritol tetra-3-mercaptopropionate, pentaerythritol tetra (3-mercaptopropionate) (PETMP), colorless liquids, water-insoluble, and widely used as intermediates for organic synthesis, modifiers in polymerization reactions such as UV coatings, inks, adhesives, etc., crosslinking agents, acidic ion exchange catalysts, low-temperature curing agents, etc. At present, the main production mode is catalytic esterification of pentaerythritol and mercaptopropionic acid. The catalysts used are mostly methanesulfonic acid, p-toluenesulfonic acid, and the like, and the synthesized product has a tetraester content of less than 70%.

Uses

Pentaerythritol Tetra(3-mercaptopropionate) can be used for additives for hair treatments.

Application

Pentaerythritol Tetra(3-mercaptopropionate) can be used as a precursor to synthesize:
Polymeric degradable networks through thiol-ene click reactions with tri/tetra-acrylates.
Thiol-ene-methacrylate composites, which are applicable as dental restorative materials.
Network solid polymer electrolytes based on polydimethylsiloxane, for lithium-ion batteries.
It can also be used to functionalize poly(high internal phase emulsions) for removal of heavy metals from water.

Flammability and Explosibility

Non flammable
