Temperature control synthesis device

Abstract

The invention relates to a temperature control synthesis device. The temperature control synthesis device comprises: a cylindrical tank body, which is provided with a middle cavity and a sealed annular inner cavity surrounding the middle cavity, wherein the sealed annular inner cavity is used for accommodating a reaction material; a driving device, which is in transmission connection with the cylindrical tank body and can drive the cylindrical tank body to rotate around the axis of the cylindrical tank body, wherein the axis of the cylindrical tank body is arranged in a horizontal or inclinedstate; a temperature control system, which comprises a heat exchange medium source and a sprayer connected with the heat exchange medium source, wherein the sprayer comprises an inner sprayer corresponding to the middle cavity and spraying towards the cavity wall of the middle cavity and an outer sprayer located on the outer side of the cylindrical tank body and spraying towards the outer side face of the cylindrical tank body. Reaction raw materials are in full contact through rotation of the tank body, in the rotating process, the materials are mainly scattered on the cavity wall face of theannular inner cavity, the reaction temperature can be effectively controlled by spraying temperature control over the interior and the exterior of the cylindrical tank body, and the device can be used for synthesizing diborane and other substances sensitive to the reaction temperature.

Description

technical field [0001] The invention belongs to the field of synthesis reaction devices, and in particular relates to a temperature-controlled synthesis device. Background technique [0002] Diborane, also known as diboron hexahydride, boroethane, molecular formula B 2 h 6 , the relative molecular weight is 27.67. The molecular configuration of diborane is very special. Among the 6 hydrogen atoms in the molecule, 4 hydrogen atoms and two boron atoms are combined with normal covalent bonds, and the other two hydrogen atoms are simultaneously bonded to two boron atoms. Atoms rely on two electrons to combine with each other to form a bond, forming a B-H-B bond, which serves as a "bridge" connecting two boron atoms. According to the normal valence bond theory, diborane needs 14 valence electrons, but it only has 12 valence electrons, so it is a typical "electron-deficient" compound. In the electronics industry, diborane is used as a dopant for gaseous impurity source, ion im...

Problems solved by technology

[0005] In the past, most of the research on the diborane dry process was in the laboratory stage. The capacity of the reaction vessel was small, and the temperature of the reaction process was easily controlled by means of laboratory cooling. The contact between solid and gas materials is insufficient, heat is easy to accumulate, and the cooling medium is difficult to ensure the consistency of the temperature in the reaction vessel, which leads to low conversion rate and high impurity content of diborane dry industrial synthesis
