Abstract

1329978 Esters of phosphorus- or arseniccontaining acids ESSO RESEARCH & ENG CO 17 June 1971 [8 July 1970] 33192/70 Heading C2P [Also in Division C5] Compounds of the general formula wherein R<SP>1</SP> is a divalent hydrogen- and carboncontaining group, R<SP>3</SP> and R<SP>4</SP> are monovalent hydrogen- and carboncontaining groups R<SP>11</SP> to R<SP>61</SP> inclusive are hydrogen or aliphatic hydrogen- and carbon-containing groups provided at least one of R<SP>11</SP>, R<SP>12</SP>, R<SP>15</SP> and R<SP>16</SP> is a hydrogen- and carbon-containing group, X<SP>1</SP>, X<SP>2</SP>, X<SP>3</SP> and X<SP>4</SP> are the same or different and are O or S atoms, Y is phosphorus or arsenic (preferably phosphorus), Z is O or S, n is 0 or 1 and p is an integer, are obtained by reacting a compound R<SP>1</SP>(X<SP>1</SP>H)(X<SP>3</SP>H) or a compound R<SP>3</SP>X<SP>1</SP>H or R<SP>4</SP>X<SP>3</SP>H, or a mixture of the compounds R<SP>3</SP>X<SP>1</SP>H and R<SP>4</SP>X<SP>3</SP>H, with an oxide or sulphide of phosphorus or arsenic and then reacting the resulting diester with a compound of the formula The first and second steps are suitably effected by heating at between 80‹ and 150‹ C. in the presence of a hydrocarbon solvent. Specified compounds for use as reactants are phosphorus pentasulphide, -pentoxide, -trioxide and -trisulphide. In an example nonyl phenol is refluxed with P 2 S 5 in xylene in a nitrogen atmosphere and the product then reacted in solution at 140‹ C. with 2-methyl-pentane-2,4- diol to give the ester of di-(nonylphenyl) dithio phosphoric acid and 2-methyl pentane-2,4-diol and the invention includes this ester per se. The products are useful as lubricating oil additives.
