Source sentences:
text: These reactions mainly use phosphorous acid (H 3 PO 3 ) as source of phosphorus.
text: It is one of the oxoacids of phosphorus, other important members being phosphoric acid (H 3 PO 4 ) and hypophosphorous acid (H 3 PO 2 ).
text: to obtain much less colored reaction crudes than with the use of acids that are very close structurally, such as phosphoric acid (H 3 PO 4 ), most particularly recommended in Patent JP 44-2964 for sorbitan esters, or orthophosphorous acid (H 3 PO 3 );
text: These include phosphorous acid (H 3 PO 3 ) and hypophosphorous acid (H 3 PO 2 ).
text: Thus, the state of oxidation of phosphorous acid (H 3 PO 3 ) is three, and phosphorous acid and its esters are referred to as P(III) species.
text: The azeotropic distillation is generally stopped after phosphorous acid (H 3 PO 3 ) is converted to its ester forms, i.e., HP(O) (OR) 2 and HP(O)
text: Because of the significant differences in hydrolysis rates between the phosphite and phosphate esters, conditions have been identified where phosphite esters are nearly quantitatively hydrolyzed to phosphorous acid (H 3 PO 3 ) while phosphate esters remain intact in the organic phase.
text: Preferred phosphorous compounds include hypophosphorous acid (H 3 PO 2 ) and phosphorous acid (H 3 PO 3 ).
