Description
Technical field
The utility model is related to chemical reaction device technical field, is filled more particularly, to a kind of vikane reactor and reaction
Put.
Background technology
Vikane, is at normal temperatures and pressures the gas of colorless and odorless.It is still stable at 400 DEG C, reactivity is less strong.
Have that diffusion permeability is strong, broad spectrum disinfestation, dosage are saved, residual quantity is low, desinsection speed fast, it is short to dissipate the gas time due to vikane,
Low temperature is easy to use, germination percentage is not influenceed and the features such as toxicity is relatively low, more and more widely applied to warehouse, freighter, collection
Vanning and building, reservoir dam, termite control and gardens are survived the winter insect, the preventing and treating of tree moth dryness insect living.
The process route of vikane synthesis has following several：Using sulfur dioxide and fluorine gas as the direct fluorination work of primary raw material
Skill；Anhydrous hydrofluoric acid technique by raw material of sulfur dioxide, chlorine and anhydrous hydrofluoric acid；Based on sulfur dioxide and nitrosyl fluoride
Want the nitrosyl fluoride technique of raw material；Chlorosulfuric acid is by being fluorinated synthesis vikane；Using fluosulfonic acid and barium chloride as the fluorine of primary raw material
Sulfonic acid technique etc., comparatively, the above two synthesis techniques report are more.
Direct fluorination, using sulfur dioxide and fluorine gas as raw material, in hydrogen fluoride and alkali metal fluoride (such as potassium fluoride)
Synthesized in the presence of under conditions of, reaction temperature -60~50 DEG C.Reaction equation is as follows：
SO2+F2→SO2F2
Although the technique yield is higher, fluorine gas production cost is higher under existing conditions, is produced into vikane
This is too high and lacks the market competitiveness.
Anhydrous hydrogen fluoride technique, using sulfur dioxide, chlorine, anhydrous hydrofluoric acid as raw material, is synthesized, instead under catalyst action
It is 150~200 DEG C to answer temperature.Reaction equation is as follows：
Main reaction：SO2+Cl2+2HF→SO2F2+2HCl
Side reaction：SO2+Cl2+2HF→SO2ClF2+HCl
Side reaction mainly just can significantly occur at a lower temperature.The technique has that cost of material is relatively low, reaction condition
Gently, the features such as technological operation is simple, is widely used in the industrial production at present, and wherein catalyst is to influence the pass of cost
Key factor.
Chlorosulfuric acid fluoride process, using chlorosulfuric acid, triethylamine-hydrogen fluoride salts as raw material, reaction at room temperature obtains vikane,
Reaction equation is as follows：
NEt3.2.6HF+SO2Cl2→SO2F2
The technique main material chlorosulfuric acid is difficult to synthesize, unsuitable industrialized production.
Fluosulfonic acid method
2HSO3F+BaCl2→SO2F2+BaSO4+2HCl
The technique equally exists main material fluosulfonic acid and should not obtain and have strong corrosivity, have to reactor material compared with
High requirement, unsuitable industrialized production.
The shortcoming of vikane reactor has in the prior art：Catalyst loading and unloading is comparatively laborious, and reaction radiating is uneven, reactor
Medium temperature can not radiate, and be easily caused side reaction, influence product quality, using complete waste material in handling and operating personnel
Directly contact, there is larger potential safety hazard, catalyst distribution and radiating are uneven, there is side reaction to occur etc..
