Abstract: 1. IN THE PROCESS FOR PREPARING PHOSPHORODITHIOIC ACIDS OF THE FORMULA

R-O-P(=S)(-SH)-O-R''

WHEREIN R AND R'' ARE EACH INDENPENDENTLY SELECTED FROM HYDROCARBYL AND SUBSTITUTED HYDROCARBYL GROUPS BY CONTACTING (A) AT LAST ONE HYDROXY COMPOUND OF THE FORMULA ROH OR R''OH, WHERE R AND R'' ARE AS DEFINED ABOVE, WITH (B) PHOSPHORUS PENTASULFIDE, THE IMPROVEMENT THEREIN COMPRISING REACTING (A) AND (B) IN THE PRESENCE OF A CATALYTICALLY EFFECTIVE AMOUNT OF AT LEAST ONE NITROGEN-CONTAINING COMPOUND SELECTED FROM THE CLASS CONSISTING OF

Y
WHEREIN X IS OXYGEN OR DIVALENT SULFUR, AND Y IS AN ALKYLENE RADICAL OF TWO TO SEVEN CARBON ATOMS WHICH, WITH THE

-NH-C(=X)-NH-

GROUP FORMS A 5-, 6-, OR 7-MEMBERED RING, AND

R"-C(=X)-N(-R1)-R2

WHEREIN X IS OXYGEN OR DIVALENT SULFUR, R" IS H, NH2ALKYL OF UP TO TWENTY CARBON ATOMS, AND EACH OF R1 AND GROUPS OF UP TO TWENTY CARBON ATOMS, AND EACH OF R1 AND R2 ARE INDEPENDENTLY H, LOWER ALKYL, OR LOWER ALKENYL WITH THE PROVISO THAT ONE OF R1 AND R2 TOGETHER WITH R" AND

-CO-N

THE GROUP CAN FORM A 5,6, OR 7-MEMBERED LACTAM.

Abstract: The invention disclosed herein is directed to an improved combustion process whereby the fuel is efficiently utilized and the formation of undesirable exhaust smoke is reduced. The combustion process comprises the burning of a fuel in which there is incorporated a small amount of metal salts having a particle size less than about 800 microns. The invention relates further to improved fuel compositions containing such metal salts.
