Claim 1
Independent Claim
184 words
A RUST INHIBITING COMPOSITION COMPRISING A MAJOR AMOUNT OF A MINERAL OIL FRACTION CONTAINING (A) BETWEEN ABOUT 0.001% AND ABOUT 50% BY WEIGHT BASED ON THE MINERAL AN ALIPHATIC OF THE REASON PRODUCT OBTAINED BY REACTING AN ALIPHATIC MONOCARBOXYLIC ACID CONTAINING FROM 10 TO 30 CARBON ATOMS WITH A POLYALKYLENEPOLYAMINE OF THE FORMULA H2N(C2H4NH)ZH, WHEREIN Z IS AN INTEGER FROM 2 TO 6 INCLUSIVE TO PRODUCE AN INTERMEDIATE PRODUCT AND REACTING AN ALKENYK SUCCINIC ACID ANHYDRIDE, WHEREIN THE ALKENYL RADICAL CONTAIND FROM 8 TO 18 CARBON ATOMS, WITH SAID INTERMEDIATE PRODUCT, THE SAID REACTION PRODUCT DISSOLVED IN THE SAID MINERAL FRACTION PROVIDING A SOLUTION CHARACTERIZED BY BEING NORMALLY SUSCEPTIBLE TO THE FORMATION OF OIL-IN-WATER EMULSIONS IN THE PRESENCE OF WATER, AND (B) BETWEEN ABOUT 0.001% AND ABOUT 15% BY WEIGHT BASED ON THE MINERAL OIL FRACTION OF A DIMERIC ACID PRODUCED BY THE CONDENSATION OF UNSATURATED ALIPHATIC MONOCARBOXYLIC ACIDS HAVING BETWEEN ABOUT 16 AND ABOUT 18 CARBON ATOMS PER MOLECULE, AND (C) ABOUT 5% TO ABOUT 20% BY WEIGHT BASED ON THE DIMERIC ACID CONTENT OF AN ACID ESTER OF PHOSPHORUS OF THE STRUCTURE
