Abstract
The invention discloses technology for preparing hydrogen chloride by reacting concentrated sulphuric acid with hydrochloric acid or sodium chloride, which is mainly characterized in that: an integrated reaction flask is provided with a hydrochloric acid addition port; a capillary tube is arranged in the integrated reaction flask; and the integrated reaction flask is connected with a flask by a connection pipeline and the flask is connected with a small funnel to form one whole body. The process is reasonable. The hydrogen chloride is easy to prepare and has high purity. The technology solves the problem of environmental pollution and is ideal hydrogen chloride preparation technology.
Description
Affiliated technical field
The present invention relates to a kind of synthetic technology of preparing of Chemicals, particularly a kind of technology that adopts the prepared in reaction hydrogenchloride of the vitriol oil and hydrochloric acid or sodium-chlor is suitable for the synthetic preparation of chemical industry hydrogenchloride.
Background technology
At present, the production technology of hydrogenchloride still can not be produced the pure hydrogenchloride of preparation also under study for action.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of technology that adopts the prepared in reaction hydrogenchloride of the vitriol oil and hydrochloric acid or sodium-chlor is provided.This technology not only technology is reasonable, and preparation is simple, and the hydrogenchloride purity height of producing, and has solved problem of environmental pollution.
The technical solution used in the present invention is: the reaction flask of design one, design has hydrochloric acid to add inlet, its interior design and installation kapillary it on, is connected with flask by connection line, is connected and installed with little funnel on the flask, is assembled into one and constitutes.
Adopt the technology of the vitriol oil and concentrated hydrochloric acid or sodium-chlor prepared in reaction hydrogenchloride, during preparation, in reaction flask, put into the vitriol oil of appropriate volume, the liquid level that makes the kapillary lower end be higher than the vitriol oil is mentioned in little funnel act, make and be full of the vitriol oil in the kapillary, stopper is installed, add inlet from hydrochloric acid and add hydrochloric acid (or sodium-chlor), the adding speed of control hydrochloric acid (or sodium-chlor) is regulated the hydrogen chloride gas flow, the thick hydrogenchloride that reaction flask chemical combination produces enters flask through connection line, react with the vitriol oil in the bottle, hydrogenchloride is produced in preparation again.
The invention has the beneficial effects as follows that technology is reasonable, preparation is simple, the hydrogenchloride purity height of production, and solved problem of environmental pollution.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Accompanying drawing number is: 1, reaction flask, 2, hydrochloric acid adds inlet, 3, connection line, 4, kapillary, 5, the vitriol oil, 6, flask, 7, the vitriol oil, 8, little funnel.
Embodiment
With reference to Fig. 1, the reaction flask 1 of design one, design has hydrochloric acid to add inlet 2, its interior design and installation kapillary 3 it on, is connected with flask 6 by connection line 3, is connected and installed with little funnel 8 on the flask 6, is assembled into one and constitutes.
Adopt the technology of the vitriol oil and concentrated hydrochloric acid or sodium-chlor prepared in reaction hydrogenchloride, during preparation, in reaction flask 1, put into the vitriol oil 5 of appropriate volume, the liquid level that makes kapillary 4 lower ends be higher than the vitriol oil 5 is mentioned in little funnel 8 acts, make in the kapillary 4 and be full of the vitriol oil, stopper is installed, add inlet 2 from hydrochloric acid and add hydrochloric acid (or sodium-chlor), the adding speed of control hydrochloric acid (or sodium-chlor) is regulated the hydrogen chloride gas flow, the thick hydrogenchloride that reaction flask 1 chemical combination produces enters flask 6 through connection line 3, react with the vitriol oil 7 in the bottle, hydrogenchloride is produced in preparation again.
