Abstract
The invention discloses a normal-temperature synthesis method of tin tetrachloride. The normal-temperature synthesis method comprises the following steps: immersing tin into tin tetrachloride liquid, adding metallic carbon nanotubes, further introducing chlorine gas, controlling the temperature in a kettle at 20-30 DEG C, controlling the pressure at 1-3Pa and controlling the flow rate of chlorine gas at 1-3m<3>/h. Tin tetrachloride is prepared by adopting gas-liquid-solid heterogeneous reaction, the metallic carbon nanotubes are taken as an auxiliary catalyst, the yield is greatly improved in comparison with gas-solid heterogeneous reaction, the improving capability can be improved by 5 times or more, and continuous and stable production can be realized.
Description
Technical field
The present invention relates to a kind of manufacture method of mineral compound, more particularly, the present invention relates to a kind of normal temperature synthesis method of tin tetrachloride.
Background technology
At present, usually use gas, Gu inhomogeneous reaction method manufactures tin tetrachloride.Because tin, chlorine reaction are thermopositive reaction, temperature of reaction exceedes the melting temperature (231.5 DEG C) of tin very soon within very short time, so the fusing usually due to tin in reaction process causes chlorine channel blockage, thus causes stopping production.In addition, because the flowing of chlorine in tin slab is flow channels, so chlorine is little in tin surfaces contact area, the residence time is short, causes chlorine utilization low, affects tin tetrachloride yield.Meanwhile, have greater environmental impacts because chlorine content in tail gas is too high.
Summary of the invention
The object of the invention is to overcome chlorine passage in above-mentioned prior art often block, the shortcomings such as tin tetrachloride yield is low, provide one not adopt gas, solid inhomogeneous reaction method, and the novel method satisfactory for result that tin tetrachloride yield is quite high
The technical scheme of employing of the present invention comprises: tin is immersed tin tetrachloride liquid, and add metallic carbon nanotubes, then pass into chlorine, and controls temperature in the kettle at 20-30 DEG C, and pressure-controlling is at 1-3Pa, and chlorine flowrate controls at 1-3m
3/ h.
The present invention produces tin tetrachloride owing to adopting gas, liquid, solid inhomogeneous reaction, and using metallic carbon nanotubes as cocatalyst, yield comparatively gas, solid non-phase reaction improves a lot, and raising ability can improve more than 5 times, can continuous and stable production.
Embodiment
