Abstract:
A continuous process for the production of choline hydroxide includes reacting ethylene oxide, trimethylamine, and water in a reaction zone to form a reaction mixture and extracting heat from the reaction mixture. Subsequently, phase separation of the reaction mixture is induced to obtain a choline hydroxide phase and an organic liquid phase comprising trimethylamine. A choline hydroxide solution (e.g., at a concentration of about 40% to 50% by weight, based on total weight of the choline hydroxide solution) is obtained from the choline hydroxide phase.
Abstract:
Novel radiotracer(s) for Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) imaging of disease states related to altered choline metabolism (e.g., tumor imaging of prostate, breast, brain, esophageal, ovarian, endometrial, lung and prostate cancer - primary tumor, nodal disease or metastases). The present invention also describes intermediate(s), pre-cursor(s), pharmaceutical composition(s), methods of making, and methods of use of the novel radiotracer(s).

Abstract:
The present invention is related to novel process for production of Tricholine Citrate by reacting citric acid with choline base at high temperature to obtained more than 65 percent pure of Tricholine Citrate. Such a obtained Tricholine Citrate is used in various composition for used as an effective iron chelator and used to stabilize animal growth hormone preparations also The invention provides a novel process for of production of Tricholine Citrate by reacting Citric acid with choline base solution at high temperature and distillation of Trichoiine Citrate at the same time in single step. In the process, citric acid is reacted with choline base solution at above 50 degree Celsius by adjusting pH of solution above 8.5 de-colorizing the solution obtained by de colorizing agent. The obtained product is filtered at temperature below the 40 degree Celsius in filtration unit and then distilled in Distillation Column to obtained high purity of Tricholine Citrate.
