Abstract:
Dialkyl-phosphinic acid alkyl esters are obtained by reacting Alpha -monoolefins being substantially free of sulfur compounds with dialkyl-phosphites in the presence of free-radical generators. The known products are foam depressants, flame retardant agents and intermediates for plant protecting agents.
