Descrição geral

Pentaerythritol is acrystalline , odour less white solid. The presence of neopentane core and four terminalhydroxyl groups makes it a versatile substrate for the synthesispolyfunctionalized compounds.

Aplicação

Pentaerythritol can be used as a starting material to prepare four armed polyurethane prepolymers, which are applicable in the synthesis of UV cured polyurethane dispersions.

It can be used as an additive in the preparation of flame retardant polymers.

It can also be used as a precursor to synthesize polyethylene glycol/4,4′-diphenylmethane diisocyanate/pentaerythritol copolymer which is applicable as heat storage material.

A nonavalent glycodendrimer bearing terminal alpha-d-mannopyranoside units has been synthesized with a convergent approach. Terminal trivalent mannoside dendrons bearing p-halophenyl ethers were prepared by glycosylation of pentaerythritol derivatives having three 2-hydroxyethyl ether substituents. Two efficient routes were developed for the
