Abstract
The utility model discloses a practical preparation system for a Wijs reagent, belonging to the technical field of chemical experiments and overcoming the defects that the Wijs reagent in the prior art is difficult to master dosage in an experiment and is larger in preparation error because an iodine trichloride reagent has large volatility. The practical preparation system mainly comprises a dissolution device and a reaction device, wherein the dissolution device comprises a beaker and an electric furnace, wherein the beaker is arranged on the electric furnace through asbestosed wire gauze; and the reaction device comprises a triangular flask, a washing bottle I, a washing bottle II and a reagent bottle which are connected in sequence through a latex tubing, wherein a separating funnel is arranged in the triangular flask. The practical preparation system disclosed by the utility model is mainly used for preparation of the Wijs reagent.
Description
Technical field
The utility model relates to a kind of practical compounding system of Webster reagent, and it belongs to chemical experiment technique field.
Background technology
Webster reagent is the acetic acid solution that contains iodine monochloride, is the special reagent that iodine number side that international standard (ISO) and CNS (GB) are formulated decides to use in the method.The preparation method of Webster reagent is to be dissolved in 700mL glacial acetic acid and the 300mL cyclohexane with iodine trichloride 9g in the GB.But iodine trichloride is unstable, highly volatile at room temperature, and the iodine trichloride reagent of purchase is because its volatility; Actual mass ratio packing indicating value will be lacked a lot, and when opening the package, iodine trichloride is volatilization rapidly; It will be appreciated that the reagent bag volatilizes the henna gas of a thread, iodine trichloride is lost again a lot, the reagent concentration that causes preparing does not reach standard; The consumption of sodium thiosulfate is held and is forbidden in the feasible experiment, thereby causes reagent preparation error bigger.
The utility model content
For solve in the prior art Webster reagent owing to iodine trichloride reagent volatility cause testing greatly in consumption difficultly hold, the bigger defective of preparation error, a kind of practical compounding system of Webster reagent is provided.
The utility model is realized through following technical scheme:
A kind of practical compounding system of Webster reagent comprises dissolver and reaction unit, and said dissolver comprises beaker and electric furnace, and said beaker is positioned on the electric furnace through asbestos gauge; Said reaction unit comprises triangular flask, wash bottle first, wash bottle second and the reagent bottle that is linked in sequence by emulsion tube, is provided with separating funnel in the said triangular flask.
Compared with prior art; The beneficial effect of the utility model is: it is easy originally to produce process operation; Personnel with certain chemical fundamentals can operate, and this preparation method reaction velocity is fast in addition, and precision is high; And, can effectively avoid the contaminated environment of chlorine to environment because whole experiment device seals; Simple in structure, can realize fast, prepare accurately, easily the purpose of Webster reagent.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the emulsion tube end in the said reagent bottle is communicated with the grass tube of 20cm.
Adopt the beneficial effect of above-mentioned further scheme to be: to prevent that chlorine from leaking, and avoids environmental pollution.

Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of practical compounding system of Webster reagent comprises dissolver and reaction unit, and said dissolver comprises beaker 1 and electric furnace 3, and said beaker 1 is positioned on the electric furnace 3 through asbestos gauge 2; Said reaction unit comprises triangular flask 5, wash bottle first 6, wash bottle second 7 and the reagent bottle 8 that is linked in sequence by emulsion tube 9, is provided with separating funnel 4 in the said triangular flask 5.
The utility model at first takes by weighing 13g iodine when experiment, be added in the beaker 1 that fills 1000ml acetate, and beaker 1 is placed on heating on the electric furnace 3, stirs with glass bar simultaneously, makes iodine be dissolved in the acetate, leaves and takes 150mL and adds in the reagent bottle 8; The concentrated hydrochloric acid that in separating funnel 4, adds 150～200mL then adds the potassium permanganate of 30～50g in triangular flask 5; With the distilled water of putting into 1/3rd volumes in the wash bottle first 6, put into the concentrated sulphuric acid of 1/3rd volumes in the wash bottle second 7.
Open the separating funnel piston, concentrated hydrochloric acid and potassium permanganate reaction generate chlorine.
