摘要:Silicatein is an enzyme of silicate-forming organisms used for the synthesis of their silicate scaffold. The present invention relates to the use of highly-expressed and highly active recombinant silicatein, silicatein isolated from natural sources after gene induction as well as silicatein-fusion proteins for the synthesis of amorphous silicon dioxide (silicic acids and silicates), siloxanes as well as modification of these compounds and their technical use.

摘要:The invention relates to a method for synthesis of aliphatic isocyanates from aromatic isocyanates in substantially 3 stages. In particular, the invention relates to a method for synthesis of bis{4-isocyanatocyclohexyl}methane (H 12 MDI) from bis{4-isocyanatophenyl}methane (MDI). More especially, the invention relates to a method for synthesis of H 12 MDI with a trans-trans isomer content of <30%, preferably of <20%, particularly preferably of 5 to 15%.

摘要:The present invention relates to a process for synthesis of flyash based Zeolite-A, said process comprising grinding and mixing of flyash and caustic soda in a ratio of 1:1.2 and optionally adding sodium aluminate or aluminium hydroxide to obtain a fine homogeneous fusion mixture; heating the said mixture in an inert vessel at about 500-600 DEG C. for about 1-2 hrs. to obtain a fused mass; cooling, milling, and mixing the said fused mass in distilled water for about 8-10 hrs. with simultaneous optional additon of sodium aluminate or alum solution, in the present or absence of NaC1 followed by optional addition of zeolite-A seeding to obtain amorphous alumino -silicate slurry; subjecting the said slurry to hydrothermal crystallisation at about 90-110 DEG C. for 2 to 4 hrs. to obtain Zeolite-A crystals; and washing the said crystals with water and then subjecting the washed crystals to oven drying at about 50-60 DEG C. to obtain the FAZ-A crystals.

摘要:Process for the synthesis of a zeolite of MTT type in the absence of any nitrogenous organic agent, from a reaction mixture containing water, a source of tetravalent silicon and ethanol and optionally a source of trivalent aluminium and a source of hydroxide ions. The products obtained after heating the zeolite in air to 70 DEG -120 DEG C. or washing with water at 60 DEG -90 DEG C. are useful as selective organophilic adsorbents or as catalysts for the conversion of hydrocarbons.
