    摘要： Suggested is a process for the production of modified alkyd resins by polymerisation of
    (a) Polyhydric alcohols,
    (b) Polycarboxylic acids, dicarboxylic acids or their anhydrides, and
    (c) Unsaturated oils or unsaturated fatty acids
    in the presence of organic solvents, which is characterised in that unsaturated dialkyl amides are used as solvents.

    摘要： Suggested are bituminous compositions for road construction, comprising as binders
    (a) at least one thinner selected from the group consisting of dialkylamides derived from unsaturated fatty acids and being capable to be chemically converted on contact with air, after the binder has been spread, and
    (b) at least one catalyst for the polymerization of the thinner under the action of oxygen.

    摘要： Suggested is a continuous process for the production of mono- or dicarboxylic acid alkyl amides, which is characterised in that:
    (a) fresh mono- or dicarboxylic acid is placed into a first reactor (R1) connected with a distillation column (C1) and subjected to a reaction with ammonia or gaseous alkyl amine to form a pre-mixture consisting of mono- or dicarboxylic acid alkyl amide and unreacted mono- or dicarboxylic acid, while the water of condensation is distilled off;
    (b) said pre-mixture is transferred into a second reactor (R2) also equipped with a distillation column (C2) and subjected to a further reaction with ammonia or gaseous alkyl amine to substantially convert all unreacted mono- or dicarboxylic acid into mono- or dicarboxylic acid alkyl amide; and
    (c) all unreacted ammonia or gaseous alkyl amine is transferred into the first reactor (R1) to start the amidation reaction.

    摘要翻译： 建议用于生产单羧酸或二羧酸烷基酰胺的连续方法，其特征在于：（a）将新鲜的单羧酸或二羧酸置于与蒸馏塔（C1）连接的第一反应器（R1）和 与氨或气态烷基胺进行反应以形成由单羧酸或二羧酸烷基酰胺和未反应的单羧酸或二羧酸组成的预混合物，同时蒸馏掉冷凝水; （b）将所述预混合物转移到还装备有蒸馏塔（C2）的第二反应器（R2）中，并与氨或气态烷基胺进一步反应，以将所有未反应的单羧酸或二羧酸基本上转化为单 - 或二羧酸烷基酰胺; 和（c）将所有未反应的氨或气态烷基胺转移到第一反应器（R1）中以开始酰胺化反应。
