    摘要: According to the process according to the invention for the preparation of anion exchange resins of the poly(meth)acrylamide type by aminolysis of bead polymers of cross-linked poly(meth)acrylic acid esters with excess polyamine, subsequent separation of the anion exchange resins from the liquid phase containing the unreacted polyamine, washing the anion exchangers free of amine with water and recovering the polyamines from the washing waters, the liquid phase containing the unreacted polyamine and the polyamine-containing washing waters are immediately mixed with the bead polymer of cross-linked poly(meth)acrylic acid ester to be subjected to aminolysis, the amount of fresh polyamine necessary for the establishment of the desired polyamine excess is added to the mixture, the mixture thus obtained is distillatively dewatered until its water content has fallen to a value of

    摘要: The invention describes citric acid esters as heating materials and fuels in stationary and mobile internal combustion engines and also in heating installations. Such propellants and fuels are characterized in particular by the fact that they burn completely without soot or with very little soot, therefore cause distinctly lower emissions of soot or fine dust than known fossil and regenerative fuels such as gasoline, diesel, kerosene, vegetable oils and biodiesel. Citric acid esters can be obtained completely from regenerative vegetable sources and are therefore CO2 neutral.
