Abstract

Complex substituted alkylene polyamines such as di(alkenylsuccinimide) of N1,N3 symmetrical bis(aminopolyazalkylene) ureas that react with boric acid in oil solution either with low boric acid utilization efficiency or react to form a hazy product whose haze cannot be removed by filtration are readily converted to the desired oil solution of boron and nitrogen containing products by first preparing an oil solution of super boron containing product of the complex substituted alkylene polyamine, combining the oil solution of super boron containing product with oil solution of the complex substituted alkylene polyamine and equilibrating the resulting mixture to a uniform boron to nitrogen content throughout.

Claims

2. The method of claim 1 wherein the boric acid is added as a slurry thereof in light mineral oil.

3. The method of claim 2 wherein equilibration is conducted at ambient temperature.

4. The method of claim 2 wherein equilibration is conducted at a temperature in the range of 120* to 250* F.
