标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.

权利人:NIPPON CATALYTIC CHEM IND
摘要:A catalyst for producing an aryl ester of a carbonic or carboxylic acid is disclosed, which includes a microporous material containing a metal element belonging to group IV. This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.

摘要:A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from −50° C. (223 K) to 200° C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.

标 题:Method for the synthesis of 2′,3′-dideoxy-2′,3′-didehydronucleosides
发明人：JIN FUQIANG; CONFALONE PASQUALE N
权利人:PHARMASSET LTD
摘要:An efficient synthetic route to antiviral 2′,3′-dideoxy-2′,3′-didehydro-nucleosides, such as 2′,3′-dideoxy and 2′- or 3′-deoxyribo-nucleoside analogs, from available precursors is disclosed, with the option of introducing functionality as needed. In one embodiment, a method for the preparation of β-D and β-L-2′,3′-dideoxy-2′,3′-didehydro-nucleosides is described that includes: activating a compound of structure (1) n n nwherein B is a pyrimidine or purine base and Y is O, S or CH 2 with an acyl halide of the formula X—C(â•?O)R 1 , X—C(â•?O)C(R 1 ) 2 OC(â•?O)R 1 or X—C(â•?O)OR 1 (wherein X is a halogen, and each R 1 is independently hydrogen, lower alkyl, alkyl, aryl or phenyl); reducing the resulting compound with a reducing agent to form a 2′,3′-dideoxy-2′,3′-didehydro-nucleoside; and optionally deprotecting the nucleoside. The haloacylation of the first step can form the 2′-acyl-3′-halonucleoside, the 3′-acyl-2′-halonucleoside, or a mixture thereof.
