专利号:US-9518047-B2 优先权日:2013-10-17 标题 :Process for the industrial synthesis of lurasidone 发明人:ANGELINI TOMMASO; BETTONI PIERGIORGIO; ROLETTO JACOPO; PAISSONI PAOLO 权利人:PROCOS SPA 摘要:Disclosed is a process for the industrial synthesis of Lurasidone from (1R,2R)-cyclohexane-1,2-diyldimethanol (1), 3-(piperazin-1-yl)benzo[d]isothiazole (3) and (3aR,4R,7R,7aS)-3a,4,7,7a-tetrahydro-4,7-methanoisobenzofuran-1,3-dione (6).). Said process is optimised to obtain Lurasidone with high yields and high purities by preparing highly pure synthesis intermediates, using critical raw materials and reagents in amounts close to the stoichiometric amounts, increasing productivity and reducing the costs and environmental impact of the process.
专利号:US-10472241-B2 优先权日:2015-10-06 标 题:Process for the synthesis of carbon nanotubes 发明人:GOSWAMI GOPAL KRISHNA; PATIL SWANAND DILIP; VEEDU SREEKUMAR THALIYIL; BALACHANDRAN VIJAI SHANKAR 权利人:RELIANCE INDUSTRIES LTD 摘要:The present disclosure relates to a process for the synthesis of highly crystalline carbon nanotubes (CNTs). Processes known in the art employ post-synthesis processes such as oxidation or hydrothermal treatment to produce CNTs with high crystallinity. The present disclosure produces highly crystalline CNTs at a low growth temperature and without hydrogen flow condition and without employing any post-production process. The process disclosed in the present disclosure produces CNTs having a crystallinity greater than 5 which makes them suitable for various industrial applications.

专利号:US-7390899-B2 优先权日:2002-09-20 标 题:Process for the synthesis of high purity 3,5-diamino-6-(2,3-dichlorophenyl) (1,2,4-triazine) 发明人:NEU JOZSEF; GIZUR TIBOR; TOERLEY JOZSEF; CSABAI JANOS; VEGH FERENC; KALVIN PETER; TARKANYI GABOR 权利人:RICHTER GEDEON VEGYESZET 摘要:The present invention relates to a new process for the synthesis of high purity 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine of formula (I) using 2,3-dichlorobenzoyl cyanide and an aminoguanidine salt as starting materials. 2,3-dichlorobenzoyl cyanide is reacted with 1-2 mol equivalent of aminoguanidine salt in 3-6 mol equivalent of methanesulfonic acid, then the obtained adduct of formula (IV) is transformed without isolation into the product with magnesium oxide. In given case the obtained crude product can be recrystallized from a proper organic solvent
专利号:US-5728363-A 优先权日:1994-04-29 标 题 :Two powder synthesis of hydrotalcite and hydrotalcite-like compounds 发明人:MARTIN EDWARD S; STINSON JOHN M; HORN JR WILLIAM E; CEDRO III VITO 权利人:ALUMINUM CO OF AMERICA 摘要:There is provided an improved method for making synthetic hydrotalcite by first reacting powdered magnesium oxide with a high surface area, transition alumina in a solution or suspension to form a meixnerite-like intermediate. This intermediate is then contacted with an anion source such as an acid, and most preferably carbon dioxide, to form the layered double hydroxide which is separated from the suspension by filtering, centrifugation, vacuum dehydration or other known means. On a preferred basis, the transition alumina combined with activated magnesia consists essentially of an rehydratable alumina powder having a surface area of 100 m 2 /g or greater. To make related double hydroxide compounds, still other reactants such as bromides, chlorides, boric acids, or salts thereof, may be substituted for the carbon dioxide gas fed into this suspension.
