Synthesis and properties of amides prepared from abietic acid and diethylenetriamine
Abstract
Chemical interaction of abietic acid with diethylenetriamine at molar ratio of 1,0 : 1,2 and temperatures of 190 and 210 °С allows to obtain a product with acid number of 55 and 18 mg КОН/g, temperature of softening of 24-26 °С and 29-31 °С respectively, mixing unlimitedly with water and thermally stable up to 300 °С. This product can be used as a functional substance, capable of giving some water repellency to paper and cardboard and improving its strength.
