    摘要： A process for the preparation of water-soluble polymeric crosslinking agents by a two-stage reaction of di-secondary diamines with epichlorohydrin and/or dichlorohydrin, wherein, in the first stage, di-secondary diamines are condensed with epichlorohydrin and/or dichlorohydrin in a molar ratio of from 1:0.5 to 1:1 at a pH of from 9 to 12, and in the second stage the condensates obtained in the first stage are reacted with additional epichlorohydrin and/or dichlorohydrin at a pH of from 4 to 8.5. The water-soluble condensates thus obtained are crosslinking agents for polyamines, polyamidoamines, ethyleneimine-modified polyamidoamines and polyether-amines. The crosslinking reaction gives water-soluble condensates, which possess a high cation activity and may be used as retention aids, drainage aids and flocculants in the manufacture of paper.

    摘要： Ionones are prepared by cyclization of pseudoionone with concentrated sulfuric acid in the presence of an organic solvent or diluent, while cooling, and by dilution of the reaction mixture with water, by a continuous process in which the pseudoionone is combined with an aliphatic or cycloaliphatic hydrocarbon which boils at 25.degree.-65.degree. C. under the reaction conditions, or an aliphatic chlorohydrocarbon, and the sulfuric acid, with thorough mixing and evaporative cooling by partial or complete vaporization of the solvent present in the reaction mixture, combination being effected so that the temperature of the reaction mixture is from 25.degree. to 65.degree. C. and the residence time of this mixture before it is diluted with water is from 0.5 to 20, preferably from 0.1 to 5, seconds.The novel process can be used to prepare .alpha.- and .beta.-ionone in a technically simple and advantageous manner and in very good yields.
