Beschreibung

Anwendung

Sodium hypophosphite hydrate can be used as:

• A radical precursor to synthesize mono alkyl phosphinic acids via radical reaction with alkenes in the presence of Et₃B as the initiator.
• A reagent for the reduction of the diazonium salt.
• A hydrogen donor in the transfer-hydrogenation reactions.
• A catalyst in the esterification reaction.

It can also be used to compose the finishing solutions for the immobilization of photo-initiator (benzophenone ) onto cotton fabrics.

Sodium hypophosphite hydrate is widely used as an esterification catalyst. It may be used to compose the finishing solutions for the incorporation of benzophenone (photoinitiator) onto cotton fabrics.
