说明

应用

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.[1]
• A reagent for the reduction of the diazonium salt.[2]
• A hydrogen donor in the transfer-hydrogenation reactions.[3]
• A catalyst in the esterification reaction.[4]

It can also be used to compose the finishing solutions for the immobilization of photo-initiator (benzophenone ) onto cotton fabrics.[5]

Sodium hypophosphite hydrate is widely used as an esterification catalyst.[6] It may be used to compose the finishing solutions for the incorporation of benzophenone (photoinitiator) onto cotton fabrics.[5][7]
