Embodiment 1

[0194] 119 g of an alkyl-ketene dimer (alkyl R about 16 carbon atoms, commercially available as "AKD" from Trigon Chemie GmbH) having a diketene equivalent of 570 g / mole were carefully melted without overheating . At 63°C, with cooling and efficient stirring, 21.4 g of 3-dimethylaminopropylamine were gradually metered in so that the internal temperature of 75°C was not exceeded. A few minutes after the spray addition was complete, the amidation was complete. The amidoamine was obtained with an amine number of 1.48 (theoretical 1.49), indicating practically 100% yield.

[0195] The amidoamine obtained is heated to 100° C. and a total of 37.2 g of methyl p-toluenesulfonate (0.95 moles per mole of tertiary amino groups in the amidoamine) are added within a period of 30 minutes. The system was reacted for an additional 2 hours at 100° C. to obtain 177.6 g of dialkylacetoacetamidoquaternary ammonium, which solidified on cooling. The product has an amine number of 0.07, which cor...

Embodiment 2

[0197] 119 g of the alkyl-ketene dimer described in Example 1 (570 g / mole of diketene) was mixed with a total of 39.2 g of bis(3-dimethylaminopropyl)amine (under the trade name "JEFFCAT Z130" commercially available from Huntsman) was gradually mixed. Shortly after capping the sparged end, the exothermic amidation reaction was complete. Afterwards, the amidoamine obtained was mixed with 74.5 g of methyl p-toluenesulfonate (0.95 mol per mole of tertiary amino groups in the amidoamine) at 100° C., added a little at a time, while the reaction mixture reached 118° C. . The reaction was allowed to complete at 100°C over the course of 2 hours. Based on an amine number of 0.11, about 94% of the tertiary amino groups are quaternized.

[0199] 5.0 g of the β-ketocarbonyl quaternary ammonium (AKD Quat1) obtained in the examples were carefully melted in a glass beaker and mixed with 0....

Abstract

Novel compositions are described, comprising (1) beta-ketocarbonyl quat compounds which contain one or more beta-ketocarbonyl groups of the general formula (I): R-CH2-(C=O)-CHR-(C=O)- and one or more quaternary ammonium groups, where R may be the same or different and is an aliphatic hydrocarbonyl radical having 6 to 28 carbon atoms, and (2) organopolysiloxanes or siloxane copolymers which are liquid at 25 DEG C and 1020 hPa.

Description

technical field [0001] The present invention relates to compositions comprising quaternary ammoniums and organopolysiloxanes and their use in fabric conditioners. Background technique [0002] EP1259672B1 describes the use of alkyl-ketene dimer dispersions (dispersions) for anti-crease finishing of textiles. Cationic emulsifiers prepared by partial reaction from alkyl-ketene dimers and polyethyleneimines are also described. Apart from these partial reaction products in which some of the amino groups of the polyethyleneimine are amidated, the dispersed alkyl-ketene dimer remains intact and ends up on the fiber as such. The quaternization of partially converted polyethyleneimine emulsifiers has not been described and is hardly economical because of the high percentage of primary and secondary amino groups. [0003] Alkyl-ketene dimer dispersions useful as textile auxiliaries are described in the following documents: [0004] CH388246 describes the use of formulations (formu...
