Provided is an apparatus for preparing silanes of the general formula HnSiCU n where n=1, 2, 3 and/or 4 by dismutation of a chlorinated silane in the presence of a catalyst, wherein the apparatus includes: a distillation column having a column bottom, a column top, at least one feed inlet, a plurality of product offtakes, and a chimney tray; and a side reactor containing a catalyst bed having an upper edge, the side reactor being connected to the distillation column via at least three pipes including a first pipe, a second pipe, and a third pipe.

Apparatus and process for preparing silanes

The invention provides a process for preparing amino acid esters and/or their acid addition salts from monomeric or polymeric amino acids, peptides, proteins and alcohols, which comprises carrying out the reaction in supercritical alcohols, preferably at pressures and temperatures which are at least 5% above the critical parameters, the alcohols serving both as the solvent and as reactants.
