Vinyltrichlorosilane synthesis device

Abstract

The invention discloses a vinyltrichlorosilane synthesis device which comprises a reaction tank, a vaporization mechanism, a conveying mechanism, a synthesis mechanism, an exhaust mechanism and a topcover plate, the vaporization mechanism, the conveying mechanism, the synthesis mechanism and the exhaust mechanism are arranged on the reaction tank, and the top cover plate is installed on the top wall of the reaction tank in a clamped mode. A rubber ring which is clamped in the installation groove and arranged in an annular mode is fixedly bonded to the bottom wall of the top cover plate, the vaporization mechanism comprises a vaporization assembly and a positioning assembly, and the synthesis mechanism comprises a synthesis tank, a condenser installed on one side of the outer wall of the synthesis tank, a temperature measurement assembly and a heat dissipation assembly. According to the vinyl trichlorosilane synthesis device, when the temperature is too high, the controller drives thefirst fan to work and rapidly discharges heat on the extension copper plate to the outside through the heat discharge pipe, so that rapid cooling can be performed, the temperature is detected in realtime, cooling is stopped when the temperature reaches an intermediate value, and the cooling process is effectively controlled,and escape of vaporized trichlorosilane and other gases is reduced.

Description

technical field [0001] The invention belongs to the technical field of vinyl trichlorosilane synthesis, and in particular relates to a vinyl trichlorosilane synthesis device. Background technique [0002] Vinyl trichlorosilane is a chemical with the molecular formula CH2=CHSiCl3, which can be used for: 1. Synthesis of various other vinyl-based silicone coupling agents; 2.

The A-150 on it has unsaturated groups and active chlorine radicals, which will be hydrolyzed violently in water to form corresponding silanols, which are suitable for glass fiber surface treatment and reinforcement Treatment agent for plastic laminates to improve the mechanical strength, heat resistance, and moisture resistance of the product; 4. It is suitable for surface treatment of glass fibers, which can improve the adhesion between glass fibers and unsaturated polyester, epoxy resin, acrylic resin, etc. Resilience, heat resista...

AI Technical Summary

Problems solved by technology

Existing devices for synthesizing vinyltrichlorosilane do not have active heat dissipation devices (usually passive heat dissipation) in the synthesis tank, resulting in low heat dissipation efficiency, and cannot timely control the temperature of the synthesis tank within the specified range, so the vaporized trichlorosilane Hydrogen silicon (and other gases) will escape because they cannot react quickly; usually acetylene gas is added through a pipe at one time, so that the added acetylene gas cannot be dispersed and mixed with vaporized trichlorosilane, causing the two to mix incorrectly. Even, it will cause an increase in side reactions in subsequent reactions
