EXAMPLES

[0193] In the following Examples and Comparative Examples, the present invention is further described in detail by taking a polyetheramine as an example of an amino polymer, but the present invention is not limited thereto. It will be apparent to those skilled in the art that other types of amino polymers can be produced based on the foregoing disclosure of the present disclosure and used as a fuel oil detergent.

[0194] The deposit generation inhibition performances in Examples and Comparative Examples were evaluated as follows.

[0195] Gasoline engine intake valve deposit simulation test method (GB19592-2004) was used.

[0196] Specifically, xylene and n-heptane were used for cleaning the pipeline, the oil circuit, and the sample bottle respectively; the sponge in the sample inlet in the sample bottle was replaced, the sample was added, the deposition plate was inserted into the slot and clamped, and the thermocouple was inserted. The timing period was set to 70 min. When the temperature rose to 165 C., the air stop valve was opened, the air flow was controlled at 700 L/h, and the air pressure was controlled at 80 kPa. Upon reaching 175 C., the fuel valve was opened, the air bubbles was discharged until no sound occurred; the indication float was stabilized at a level of 30, and the spraying of sample was controlled and finished within 70-75 min. The fuel valve and air valve were closed. The atmosphere was maintained at 175 C., and the timing was reset to 10 min. The heating was turned off, and the deposition plate was cooled naturally and then soaked in n-heptane for 6 mins. The deposition plate was taken out, balanced and weighed, and the difference between the blank and the deposition plate was the amount of the produced deposit.

[0197] The deposit reduction rate was an important indicator for evaluating the detergency of detergents. The greater the deposit reduction rate, the stronger the detergency. Based on the Gasoline engine intake valve deposit simulation test method (GB 19592-2004), the amount of the produced deposit (m.sub.IVD, mg) was measured, and the deposit reduction rate was calculated according to the following equation:

[00001] $Deposit .Math. .Math. Reduction .Math. .Math. Rate = \frac{m_{IVD, 0} - m_{IVD}}{m_{IVD, 0}} 100$

wherein, m.sub.IVD,0 and m.sub.IVD are the production amounts of the deposits in the simulated intake valves with the blank gasoline and the detergent-added gasoline, in unit of mg.

The mixture was warmed up to 60 C., and 453 g of hydrogen peroxide (well mixed) was added dropwisely in two hours to the four-necked flask. The mixture was reacted for 2-8 hours.

[0206] FIG. 1 is a comparison graph of the infrared spectrum of alkenyl polyether, epoxy polyether, and polyetheramine in Example 1. In the figure, curves A, B, and C in order from top to bottom respectively represent the infrared spectrum of alkenyl polyether, epoxy polyether, and polyetheramine. In the figure, the curves A, B and C have the characteristic peak at 3471 cm.sup.1 for the terminal hydroxyl group, the strong and broad symmetric stretching vibration absorption peak at 1108 cm.sup.1 for the ether bond COC, and the absorption peaks at 2900 cm.sup.1, 1300 cm.sup.1 and 1460 cm.sup.1 for characterizing the CH stretching vibration and the deformation vibration of the CH.sub.2 and CH.sub.3 groups. The main differences appears between 1500 and 1700 cm.sup.1, for the curve A, the stretching vibration peak of the starting material alkenyl polyether carbon-carbon double bond, CC absorption peak, is located at 1670-1620 cm.sup.1 and its intensity is relatively weak; for the curve B, due to the epoxidation of the double bond of epoxy polyether, the absorption peak at this location disappears; for the curve C, the primary amine of the product polyetheramine has an in-plane bending vibration, the NH is located at 1650-1500 cm.sup.1, the primary amine has a moderate NH adsorption intensity, and the secondary amine has a weak adsorption intensity.

[0207] FIG. 2 is a .sup.1H NMR spectrum of the epoxy polyether as an intermediate product of Example 1. In the figure, the peaks at 2.60-2.80 ppm and 3.01-3.20 ppm are the shift peaks of the epoxy hydrogen. The double bond peak at 4-6 ppm is significantly reduced, indicating that most of the terminal hydroxyl groups have been epoxidized.

[0208] FIG. 3 is an enlarged .sup.1H NMR spectrum of the epoxy polyether as an intermediate product of of Example 1. It can be seen that the peak integration area at 3.20 ppm is about half the peak area at 2.61-2.80 ppm, just demonstrating the number of H{circle around (10)} is half the number of H{circle around (9)}.

[0209] FIG. 4 is a .sup.1H NMR spectrum of the polyetheramine as the product of Example 1. In the figure, the peaks at 3.3-4.0 ppm corresponds to the hydrogen {circle around (2)}{circle around (4)}{circle around (5)}{circle around (7)} of methylene in epoxy polyether, the peaks at 0.9-1.7 ppm corresponds to the hydrogen {circle around (3)}{circle around (6)} of methyl in epoxy polyether, and the shift of the hydrogen of two methylene groups in the introduced ethylene diamine is located at 2.66-2.80 ppm. The hydrogen in the hydroxyl and amino groups is located at 1-6 ppm. The shift of a small amount of double bonds at 4-6 ppm demonstrates the alkenyl polyether is not completely reacted.

[0210] FIG. 5 is an partially enlarged .sup.1H NMR spectrum of the polyetheramine as the product of Example 1. It can be seen that the peak integration area at 3.20 ppm (corresponding to H{circle around (10)}, one hydrogen atom at said location) is about one sixth of the peak integration area at 2.80 ppm (corresponding to H{circle around (9)}, Hc, Hd, six hydrogen atoms in total). The ratio of the peak areas at two locations is identical to the ratio of the hydrogen atom numbers at the corresponding position in the molecular formula.

[0211] FIG. 6 is a comparison graph of the .sup.1H NMR spectrum of alkenyl polyether, epoxy polyether (intermediate), and polyetheramine (product) in Example 1. In the figure, curves A, B, and C in order from top to bottom respectively represent the .sup.1H NMR spectrum of alkenyl polyether, epoxy polyether, and polyetheramine.

[0212] As can be seen from the figure, for the curves B and C, the double bond peaks at 4-6 ppm are significantly reduced, indicating that most of the double bonds are completely reacted. The shift of the intermediate epoxy polyether occurs at 2.60-3.06 ppm, corresponding to H on the epoxy group. In the .sup.1H NMR spectrum of the final polyetheramine, the hydrogen shift on the epoxy bond disappears, and the hydrogen on two methylene groups of ethylenediamine appears at 2.74-2.82 ppm.

[0213] FIG. 7 is a comparison graph of the enlarged .sup.1H NMR spectrum of alkenyl polyether, epoxy polyether (intermediate), and polyetheramine (product) in Example 1. In the figure, curves A, B, and C in order from top to bottom respectively represent the partially enlarged .sup.1H NMR spectrum of alkenyl polyether, epoxy polyether, and polyetheramine. For the curves B and C, the occurrence of the peak at 3.20 ppm corresponds to the formation of H{circle around (10)}), and for the curve C, the occurrence of the peak at 2.74-2.82 ppm corresponds to the shift of hydrogen in the newly introduced ethylene diamine.
