  • Publication number: 20150239341
    Abstract: Disclosed is a fuel injection hole cap for preventing explosion due to static electricity which is characterized in that it is possible to prevent any fire due to an explosion of fuel evaporation gas in such a way to instantly discharge static electricity the instant that a user touches with a hand injection hole cap before the fuel injection hole cap is opened, without carrying any device with him which is configured to prevent the occurrence of static electricity. For this, at the fuel injection hole cap of a vehicle, there is provided a static electricity discharger which is configured to discharge static electricity and flash by the current of the discharging, thus informing the use of the discharging.

  • Publication number: 20100168433
    Abstract: A process for stereospecific preparation of bepotastine of formula (I) and novel intermediates used therein having formulae (II) to (IV) are provided. The inventive process comprises subjecting (RS)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine to a reaction with a 4-halobutanoic acid l-menthyl ester, halo being chloro, bromo or iodo, in an organic solvent in the presence of a base to produce (RS)-bepotastine l-menthyl ester of formula (II), conducting a reaction of the compound of formula (II) with N-benzyloxycarbonyl L-aspartic acid in an organic solvent to induce selective precipitation of bepotastine l-menthyl ester.N-benzyloxycarbonyl L-aspartate of formula (III), filtering the precipitates formed in step 2) to isolate the compound of formula (III), treating the compound of formula (III) with a base to liberate bepotastine l-menthyl ester of formula (IV), and hydrolyzing the compound of formula (IV) in the presence of a base.
