  • Patent number: 8333107
    Abstract: Very accurate measurements of mass transfer can be made rapidly by permitting diffusion of an agent desired to be measured into or out of a small, very precisely known volume of a microdialysis probe, then rapidly pumping or flushing (“pulsing”) the probe with a known volume of fluid as a single pulse. The diffusion and pulsing may be repeated. The method, hereinafter called pulsatile microdialysis (PMD) to distinguish it from prior art continuous flow microdialysis, is useful for measurements in a number of processes, including protein binding, adsorption to binding agents such as activated charcoal, release from microemulsion drug delivery systems, determination of drug diffusion coefficients and concentrations, and for various other purposes. The method is based on mathematical manipulation of Fick's Laws. Resulting equations were verified against experimental data using methazolamide, warfarin and benzocaine as test drugs.

  • Patent number: 5112795
    Abstract: A process for preparing a supported silver catalyst for the production of alkylene oxide by the vapor phase oxidation of alkylene with an oxygen-containing gas is disclosed and comprises contacting a silver-contacting support with a solution comprising a metal-containing promoter other than alkali metals or alkaline earth metals. The solution is chosen so that the metal-containing promoter has an increased affinity to the silver-containing carrier relative to its affinity to the carrier without silver. Alkene epoxidation catalysts and alkene epoxidation processes are also disclosed.

  • Patent number: 4849559
    Abstract: A process is provided for the preparation of the dimer, dichloro-[2,2]paracyclophane, which is useful as the starting material for the deposition of conformal parylene coatings employed, for example, in the electronics industry for the protection of various sensitive electronic components.The process avoids the normally low yields of chlorinated dimer formed by the chlorination of 2,2-paracyclophane and instead utilizes the Hofmann elimination of 2(3)-chloro-p-methylbenzyltrimethylammonium hydroxide by conducting the elimination reaction under carefully controlled conditions of reaction temperature and profile, reaction feed configuration, water concentration in the reactor and the use of a cosolvent, certain reaction promoters, or a combination thereof.
