| abstract | 1,251,031. Organophosphorus sequestrants. HOOKER CHEMICAL CORP. 14 Oct., 1968 [2 Nov., 1967], No. 48613/68. Heading C2P. [Also in Division C1] The invention comprises compounds of the Formula I or II where Y is -OH or -SH, or an alkali metal salt thereof, b is 0 or 1, d is 0 to 3, d<SP>1</SP> is 0 to 2, X<SP>1</SP> and X<SP>3</SP> are each oxygen or sulphur, R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are each hydroxy or an aminocarboxylic group of the Formula III R<SP>13</SP> is a group of Formula III, f is 0 or 1, X<SP>2</SP> is hydrogen, ammonium or alkali metal, R<SP>4</SP>, R<SP>5</SP>, R<SP>6</SP> , R<SP>7</SP>, R<SP>8</SP>, R<SP>9</SP>, R<SP>14</SP> and R<SP>15</SP> are each hydrogen, alkyl, alkoxy hydroxy, aralkyl, aryl, alkaryl, hydroxyaryl, alkoxyaryl or a group of Formula III, R<SP>10</SP>, R<SP>11</SP> and R<SP>12</SP> are each hydrogen or alkyl, n is 1 or 2 and g is at least one, provided that R<SP>1</SP> is a group of Formula III when at least one of R<SP>4</SP> and R<SP>5</SP> is alkyl of at least two carbon atoms, provided that R<SP>2</SP> is a group of Formula III when at least one of R<SP>6</SP> and R<SP>7</SP> is alkyl of at least two carbon atoms, provided that R<SP>3</SP> is a group of Formula III when at least one of R<SP>8</SP> and R<SP>9</SP> is alkyl of at least two carbon atoms, and provided at least one of R<SP>1</SP> to R<SP>9</SP> is a group of Formula III at least when one of R<SP>4</SP> to R<SP>9</SP> is hydrogen or alkyl, provided (1) that at least one of R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> is a group of Formula III (A) at least when b is one and (B) when at least one of R<SP>4</SP> to R<SP>9</SP> is OH and (2) that X<SP>3</SP> is sulphur when Y is SH and oxygen when Y is OH. The compounds of Formulµ I and II, which may be used as metal sequestrants (see Division Cl), may be prepared by reacting a tetrakis (hydroxyalkyl) phosphonium salt with a suitable aminocarboxylic acid, and optionally oxidizing. |
