Process for the production of fuel additives from chlorinated polybutenes. |
摘要 |
<p>A process for preparing a polybutene amine composition comprises the steps of reacting a chlorinated polybutene with an excess of at least one mole of at least one type of an amine compound per mole of the chlorinated polybutene at a reaction temperature of at least about 100°C; neutralizing the reaction mixture with a base selected from the group of alkali metal and alkaline earth metal alkoxides and amides with formation of one of an alcohol or ammonia, respectively; neutralizing any excess base with an acid that will produce essentially no water as a by-product; and recovering the polybutene amine composition, the process including the steps of removing the alcohol or ammonia in a timely fashion; and removing excess of the amine compound.</p><p>The present invention allows the manufacture of polybutene amine fuel deposit control additives, without the undesired by-products or environmental disadvantages of prior art procedures.</p> |
