A module for the synthesis of organic molecules on or in solid phase and an apparatus comprising at least such a module. The module consists of several synthesis reactors formed, each, by a tubular body forming a reaction chamber delimited in its lower part by a removable porous wall, designed to retain the synthesis support material, an injection and expanding head forming an upper closure plug for the tubular body, a closure and emptying base mounted removable in a lower extension of the tubular body. Each reactor is provided with a heat exchanger in close peripheral contact with the tubular body at least at the part of the chamber designed to contain the medium and the reaction compounds and a condenser in close peripheral contact with the body at the part of the chamber extending above that containing the medium and the reaction compounds and beneath the injection head.
Module for the synthesis of molecules, particularly organic, on or in solid phase, characterized in that it is principally constituted by several, preferably at least two and at most ten, separate synthesis reactors (2), arranged in a circular arrangement with equiangular distribution and each formed by a tubular body (3) forming a reaction chamber (3′) delimited in its lower portion by a removable porous wall (4), adapted to retain the material forming a synthesis support, by a head (5) for injection and expansion forming an upper closure plug for the tubular body (3), and by a base (6) for closing and emptying, mounted removably in a lower prolongation (3″) of the tubular body (3) and ensuring the peripheral sealed holding of the retention wall (4), each reactor (2) being provided with a heat exchanger (7) in intimate peripheral contact with the tubular body (3) at the level of the portion (3′″) of the chamber (3′) adapted to contain the medium and the reaction compounds, and by a condenser (8) in intimate peripheral contact with the body (3) at the level of a portion (3″″) of the chamber (3′) extending above the latter (3′″) containing the medium and the reaction compounds and below the injection head (5), and said assembly of reactors (2) being mounted in an insulating structure (9) surrounding said reactors (2) at the level of said exchangers (7) and said condensers (8), the action of these latter being similar for all the reactors (2) of the module (1) and the insulation being homogeneous for all the reactors (2), such that said reactors (2) will be continuously subject to identical thermal conditions, wherein the insulating structure (9) is constituted by portions of rigid insulating material (9′), peripherally surrounding the assembly of reactors (2) and forming substantially a ring about this latter, and by an insulating material (9″) that is pulverulent or formed of balls of small diameter contained in the ring formed by the portions of rigid insulating material (9′) and filling the free volumes between said bodies (3) of the different reactors (2).
