Patent number: 10818951Abstract: A hydrogen fuel, sustainable, closed clean energy cycle based on green chemistry is presented for large scale implementation using a cost effective electrolytic cell. A chemical reaction between salinated (sea) or desalinated (fresh) water (H2O) and sodium (Na) metal produces hydrogen (H2) fuel and sodium hydroxide (NaOH) byproduct. The NaOH is reprocessed in a solar powered electrolytic Na metal production plant that can result in excess chlorine (Cl2) from sodium chloride (NaCl) in sea salt mixed with NaOH, used to effect freezing point lowering of seawater reactant for hydrogen generation at reduced temperatures. The method and molten salt electrolytic cell enable natural separation of NaCl from NaOH, thereby limiting excess Cl2 production. The recovered NaCl is used to produce concentrated brine solution from seawater for hydrogen generation in cold climates, or becomes converted to sodium carbonate (Na2CO3) via the Solvay process for electrolytic production of Na metal without Cl2 generation.Type: GrantFiled: May 12, 2018Date of Patent: October 27, 2020Inventor: Alvin Gabriel Stern

Patent number: 8497374Abstract: A synthetic process for producing bortezomib comprising converting racemic boronic esters, such as the pinacol ?-aminoboronic ester, into mixtures of diastereomers [6] by reaction with a suitably protected L-phenylalanine derivative (see Scheme 3), such as N—BOC-L-phenylalanine. The protecting group of the L-phenylalanine moiety is then removed, such as by reacting the diastereomers [6] with an acid, such as hydrochloric acid, to form a mixture of amine salt diastereomers [7] which is then subjected to conditions under which the desired diastereomer (R,S)-[7] is selectively isolated, such as by crystallization, chromatography or stereoselective hydrolysis. The separated desired diastereomer (R,S)-[7] is then converted into bortezomib or bortezomib anhydride.Type: GrantFiled: May 12, 2011Date of Patent: July 30, 2013Assignee: Scinopharm Taiwan, Ltd.Inventors: Julian Paul Henschke, Aiping Xie, Xin Yan Huang, Yung Fa Chen
