The Ingredients
Copper Sulfate. The copper sulfate which is useful in this invention is cupric sulfate, preferably the dehydrated variety CuSO4·no H2O. Experiments have shown that the synergistic catalytic activity of this compound exceeds that of iron or ferrous sulfate previously used by a substantial degree.
Picric Acid. This trinitrophenol acts synergistically with the cuprous sulfate to give the active component of this invention.
The Aromatic Solvents. Preferably as aromatic solvent, toluene is. utilized. Of the alkyl benzenes possible, toluene, ortho-, meta-, and para-xylenes are preferred and the mesitylenes are operable. In some of the applications herein the toluene is replaced with other less toxic solvents.
The Alcoholic Solvents. Of the lower alkanols useful in this invention methyl alcohol and isopropanol are preferred, although any C1 -C6 lower alkanol straight- or branch-chain can be used. Of additional interest is normal butyl alcohol which is used in the formulation designed to give a high flash point.
Nitrobenzene. This compound is utilized as an additional solvent. It is miscible with alkanols and is a superior organic solvent for the picric acid.
Primene. Primenes are tertiary alkylamines which are a cross of primary aliphatic amines of the general formula R1 (R2) (R3)CNH2 in which the amino group is linked to a tertiary carbon atom. The amines utilized in this invention are Primene 81R and Primene JM-T, with the 81R preferred. These amines are anti-oxidants and stabilizers for fuel oils and jet fuels.
Example 1
Prior to testing, all vehicles had their catalytic converters removed. The test sequence began with a baseline Federal Test Procedure (FTP) and Highway Fuel Economy test (HFET). Next replicate FTP and HFET tests were performed to verify data repeatability. Following this the first additive was combined with the commercial unleaded fuel at a ratio of 1 ounce of additive for every 12 gallons of fuel. An FTP/HFET test series was performed and replicate tests followed immediately.
The catalytic converters were welded in position prior to the next test series. Baseline FTP and HFET tests were conducted and replicate baseline tests followed. The same additive used for testing without catalytic converters was then added at the same 12:1 ratio. FTP/HFET testing with additive was performed on all vehicles with replicate tests immediately thereafter.
The catalytic converters were again removed. Next each vehicle received 400 miles of mileage accumulation using the Automotive Environmental Systems, Inc. highway/city mileage accumulation driving schedule. The mileage accumulation was done with XRG additive in the commercial unleaded fuel. The additiva used for the mileage accumulation and the tests following mileage accumulation was not the same additive used in the previous test series. All additives were unmarked. After mileage accumulation the vehicles received FTP/HFET series with replicate tests.
Between the baseline FTP/HFET and the mileage accumulation with the second additive, the vehicles incurred an average of 1672 miles. The Chevrolet Monte Carlo (#0051) had 1591 miles; the Ford LTD (#0052) had 1740 miles; and the Buick Regal (#0053) had 1686 miles. The miles were accumulated with and without catalytic converters, with commercial unleaded fuel and with commercial unleaded fuel with an additive.
