  • Determining infections in liquid samples by detecting short-chain fatty acids and ammonia in the headspace associated with the liquid sample using polymer sensors
    Patent number: 6921668
    Abstract: A method for determining the presence of an infection in a liquid sample comprising the steps of: lowering the pH of the liquid sample so as to drive short-chain fatty acids present in the liquid sample, acetic acid in particular, to the gaseous phase; detecting short-chain fatty acids, ammonia and, optionally amine species present as gases in a headspace associated with the liquid sample using a detector which is sensitive to the presence of short-chain fatty acids, ammonia and, optionally, amine species, particularly conductive and semi-conductive polymer sensors; and correlating the presence of detected short-chain fatty acids, ammonia and, optionally, amine species with the presence of the infection.

  • Process for preparaing (E)-methyl 2-[2-(6-(2-cyanophenoxy)-pyrimidin-4-yloxy)phenyl]-3-methoxypropenoate in the absence of copper(salt) and of N,N-dimethylformamide
    Patent number: 6153750
    Abstract: A process for preparing (E)-methyl 2-[2-(6-(-cyanophenoxy)pyrimidin-4-yloxy)phenyl]-3-methoxypropenoate comprising contacting (E)-methyl 2-[2-(6-chloropyrimidin-4-yloxy)phenyl]-3-methoxypropenoate or methyl 2-[2-(6-chloropyrimidin-4-yloxy)phenyl]-3,3-dimethoxypropanoate with 2-cyanophenate anions, the process being conducted in the absence of copper or a copper salt and in the absence of N,N-dimethylformamide. The 2-cyanophenate anions are generated in situ by reacting 2-cyanophenol with an alkali metal carbonate.
