  • Publication number: 20140189960
    Abstract: An improvement for boosting the cleaning capacity of liquid washing compositions provides for the use of a combination of one or more secondary paraffinsulfonates having 8 to 22 carbon atoms and amylase for increasing the cleaning capacity of the liquid washing compositions with respect to starch-containing stains on textiles. In accordance with the invention, it is possible to lower the amount of liquid washing composition with comparable cleaning performance, which brings environmental advantages. Moreover, it is possible to clean at low temperatures, which can reduce energy consumption.

  • Patent number: 8148530
    Abstract: The present invention relates to a process for the preparation of 3,7-diazabicyclo[3.3.1]nonane compounds. According to the invention, in a first step, a dicarboxylic acid ester is reacted with a pyridine aldehyde and a primary amine. The piperidone which forms is reacted in a second stage with formaldehyde and a further primary amine. It is essential to the invention that, in the first reaction stage, a C2-C4-alcohol is used as solvent and, in the second reaction stage, a C3-C4-alcohol is used as solvent.

  • Patent number: 7977487
    Abstract: The invention relates to a method for producing the compositions cited in the title. According to this method: dipyridyl ketone is reacted with hydroxylamine; the oxime obtained thereby is reduced without intermediate isolation to form 1,1-di-(2-pyridyl)-methylamine, and; this amine is firstly reacted with 1 to 1.5 molar equivalent of picolyl chloride and then with another 1 to 1.5 molar equivalent of picolyl chloride to form the amine of formula (1). This amine is purified via the tetrafluoroborate salt and subsequently alkylated with an alkyl iodide. This method represents an improvement with regard to prior art methods for producing these compounds.
