摘要
Preparation of a modified montan wax (I) comprises melting the montan wax first at 100-140[deg]C, subsequently adding tall resin (3-mass %) or its ester under agitation, introducing various acid groups in the presence of mineral acids with oxidizing effect under air injection to the obtained wax resin mixture, agitating at 110-150[deg]C, and converting the acid groups by adding alkali hydroxide (0.7-4.5 mass %) into corresponding salts. An independent claim is also included for (I), which is a product from a purposeful chemical reaction of tall resin or its ester mixed with montan wax, where acid groups transferred into its salts are present in molecular skeleton.
