摘要:A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C 2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl 3 or Rh(NO 3 ) 3 . The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts. The obtained catalysts show high activity and selectivity in the synthesis of C 2 -oxygenates by the hydrogenation of CO under mild process conditions.

摘要:Methods are provided for synthesizing crystals having a ZSM-5 framework structure from synthesis mixtures suitable for synthesis of ZSM-12 framework structure crystals in the absence of seed crystals with a ZSM-5 framework structure, such as in the absence of any seed crystals. For synthesis mixtures with a sufficiently high XO 2 :Y 2 O 3 ratio, seeding a synthesis mixture with ZSM-5 seed crystals can result in production of pure phase ZSM-5 crystals with a new morphology. The morphology can include rod-like primary crystallites with a length of about 0.5 μm or less that are organized/aggregated into larger secondary crystal structures. The aggregation of the primary crystallites into a secondary crystal structure can allow for an unexpectedly large mesoporous surface area for the ZSM-5 crystals.

摘要:The present invention provides a process for the synthesis of opioid prodrugs. In particular, the present invention provides a process for the synthesis of opioid prodrugs comprising: treating an opioid, in the form of a salt or a freebase, with a carbonyl synthon to form an activated intermediate and subsequently reacting the activated intermediate with an amine, in the form of a salt or a freebase.

摘要:The invention relates to a process for the electrochemical synthesis of alkali metal alcoholates (alkoxides) and/or for the regeneration of the catalyst from methyl formate synthesis from alcoholic solutions of salts of alkali metals in an electrolysis apparatus with an ion-selective membrane. The electrolysis is carried out in the presence of a defined quantity of a potassium salt or sodium salt of a perfluoroalkanesulphonic acid accompanied by the use of non-oxidisable anode material and with a membrane based on a sulphonated styrene-divinylbenzene copolymer. The process enables an increase in the selectivity of the procedure and a continuous synthesis.
