Abstract: MINERAL HYDROCARBON FEEDSTOCKS WHICH ARE SUBJECTED TO ELEVATED TEMPERATURES OF THE ORDER OF 200* TO 1300*F. AND WHICH HAVE A TENDENCY TO FORM DEPOSITS BY REASON OF SUCH HEATING HAVE ADDED THERETO MINOR AMOUNTS, OF THE ORDER OF 1 TO 400 PARTS PER MILLION BY WEIGHT, AS A PRETREATMENT OF A CONDENSATION PRODUCT OF A LONG CHAIN ALKYL OR ALKENYL MONOCARBOXYLIC ACID, DICARBOXYLIC ACID OR ANHYDRIDE THEREOF, HAVING A NUMBER AVERAGE MOLECULAR WEIGHT BETWEEN ABOUT 600 AND ABOUT 5000, AND AT LEAST ONE POLYALKYLENE POLYAMINE AND AN ADDITION SMALL AMOUNT OF A PHOSPHOROUS ACID OR A MONO--, DI- OR TRIORGANIC PHOSPHITE ESTER HAVING THE FORMULA:

R1-O-P(-O-R2)-O-R3

WHEREIN R1 IS HYDROGEN OR A HYDROCARBON RADICAL SUCH AS ALKYL, ARYL, ALKARYL, CYCLO ALKYL, ALKENYL, ARALKYL OR SIMPLE CHLORINATED SUBSTITUENTS THEREOF AND R2 AND R3 ARE HYDROGEN OR ARE SELECTED FROM THE SAME GROUP AS SHOWN FOR R1. BEST ANTIFOULANT RESULTS ARE OBTAINED WHERE THE CONDENSATION PRODUCT AND THE PHOSPHOROUS COMPOUND AS ADMIXTURES OR AS THE PREREACTED COMPOUND OF THESE TWO TYPES OF ADDITIVES ARE ADDED TO THOSE FEEDSTOCKS WHICH CONTAIN OXIDIZED HYDROCARBONS AND/OR UNSATURATED HYDROCARBONS.

Abstract: MINERAL AND SYNTHETIC OIL COMPOSITIONS, SUCH AS GASOLINE, FUELS, LUBRICANTS, ETC., ARE STABLILIZED AGAINST SLUDGE FORMATION, COLOR DEGRADATION, ETC., BY THE ADDITION THERETO OF 1-AZA BICYCLO ALKANES HAVING FROM 5 TO ABOUT 9 CARBON ATOMS IN THE SKELETAL RINGS WITH THE AZA NITROGEN BEING A BRIDGEHEAD NITROGEN.
