Abstract: Title:   PHOSPHORUS-  AND/OR  NITROGEN-CONTAINING DERIVA-TIVES  OF  SULFUR-CONTAINING  COMPOUNDS,  LUBRI-CANT, FUEL AND FUNCTIONAL FLUID COMPOSITIONS                  Abstract of the Disclosure This   invention   is  directed  to  phosphorus-and/or    nitrogen-containing   derivative   compositions useful  particularly  in  fuels,  and  in lubricating and functional  fluid  compositions.    The derivative compo-sitions   comprise  a  phosphorus-  and/or  nitrogen-con-taining   derivative   composition  of  sulfur-containing compounds prepared by the process comprising reacting (A)  at  least  one  sulfur composition from the group of (A-1) compounds    characterized    by   the structural formula     (I) wherein R1, R2, R3  and  R4  are  each  independent-ly H or hydrocarbyl groups;         R1 and/or R3 may be G1 or G2; R1   and  R2  and/or  R3 and  R4  together  may be  alkylene  groups containing about 4 to about 7 carbon atoms;     G1   and   G2   are  each  independently  C(X)R, COOR,   C?N,   R5-C=NR6,   CON(R)2,   or   NO2,   and  G1 may  be  CH2OH,  wherein  X  is  O or S, each of R and R5 are  independently  H  or a hydrocarbyl group, R6 is H or a hydrocarbyl group:         when   both   G1   and   G2   are  R5C=NR6,  the two  R6  groups  together  may  be a hydrocarbylene group linking the two nitrogen atoms;         when   G1    is   CH2OH   and   G2   is  COOR,  a lactone  may  be  formed by intramolecular combination of G1 and G2; and x is an integer from 1 to about 8; and (A-2) compositions   prepared   by  reacting sulfur   and/or  sulfur  halides  with compounds     represented    by  the structural formulae                      (II) (III) wherein each   of   R7   is   independently   H   or   a hydrocarbyl group;         R8   is   H,   a   hydrocarbyl   group,   or   a hydrocarbyloxy group;     G3 is C(X)R, C?N, COOR, CON(R)2, NO2 or R5C=NR6 wherein   X,  R, R5 and  R6 are  as  defined above,; and y is an integer from zero to 5; with (B)  a   di-  or trihydrocarbyl  phosphite,  at least  one  amine  compound containing at least one NH or NH2  group,  or  a  combination  of  said  phosphite  and amine,  provided,  however,  when  G1  and  G2  in  (A-l) are  -C(X)R,  (B) is a di- or tri-hydrocarbylphosphite or a  mixture  of  said  phosphite  and  an  amine  compound containing at least one NH or NH2 group.         The  compositions  of  the  invention  also  may include (C)  at    least   one   carboxylic   dispersant composition  prepared  by  the reaction of a hydrocarbon-substituted  succinic  acid-producing  compound  with  at least   about  one-half  equivalent,  per  equivalent  of acid-producing  compound,  of an organic hydroxy compound or amine  containing at least one hydrogen attached to a nitrogen  atom, or a mixture of said hydroxy compound and amine.         The  lubricating  compositions  of  the  present invention  are  particularly  useful as lubricating oils, functional  fluids  and  greases.    The  invention  also relates  to  fuels  and  aqueous  systems  containing the above-described derivative compositions.
