    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： Suggested is the use of microcapsules having an average diameter of 0.1 to 25 µm, obtainable in that
    (a1) an emulsion is prepared comprising actives and optionally oil components and/or emulsifiers,
    (a2) said composition is treated with aqueous solutions of anionic polymers to form a matrix,
    (a3) said matrix is brought into contact with aqueous solutions of cationic polymers to form a capsule and optionally
    (a4) said capsules being separated off from the aqueous phase,

    or
    (b1) an emulsion is prepared comprising actives and optionally oil components and/or emulsifiers,
    (b2) said composition is treated with aqueous solutions of cationic polymers to form a matrix,
    (b3) said matrix is brought into contact with aqueous solutions of anionic polymers to form a capsule and optionally
    (b4) said capsules being separated off from the aqueous phase,

    for making paints and lacquers.
