Abstract
The present invention provides a kind of and produces the method that low-concentration hcl during germanium prepares concentrated hydrochloric acid, it is characterized in that: in closing enamel still, be sequentially added into low-concentration hcl, ammonium chloride solution, it is passed through chlorine in the case of enamel still is heated to react, the Design Conception of the present invention in industry belongs to and proposes first, sustained response by ammonium chloride Yu chlorine, increase the concentration of hydrochloric acid, be collected processing to the nitrogen produced simultaneously, there is good industrial prospect.
Description
Technical field
The present invention relates to chemistry, metallurgical technology field, during espespecially a kind of production germanium, low-concentration hcl prepares high concentration
The method of hydrochloric acid.
Background technology
Germanium stable chemical nature, under room temperature not with air or water vapor acting, but when 600～700 DEG C, quickly generate two
Germanium oxide, inoperative with hydrochloric acid, dilute sulfuric acid, concentrated sulphuric acid is when heating, and germanium can slowly dissolve, and in nitric acid, chloroazotic acid, germanium is readily soluble
Solving, aqueous slkali is the most weak with the effect of germanium, but melted alkali is in atmosphere, and germanium can be made to dissolve rapidly, and germanium is inoperative with carbon, so
Melting in graphite crucible, will not be polluted by carbon, germanium, stannum and lead are to belong to family together in the periodic table of elements, both quilts morning rear
It is found that ancient times and utilize, and germanium is not the most by plant-scale exploitation, this is not due to germanium in the earth's crust
Content few, and being because it is one of the most scattered element in the earth's crust, and germanic Ore is little, and the extracting method of germanium is
First by the concentrated hydrochloric acid chlorination of the enriched substance of germanium, produce germanium tetrachloride, then remove main arsenic impurities with hydrochloric acid solvent extraction,
Then through twice rectification and purification of quartz towers, then wash through high purity hydrochloric acid, available high-purity germanium tetrachloride, make four chlorinations with high purity water
Germanium hydrolyzes, and obtains high-purity germanium dioxide, and some impurity can enter hydrolysising mother liquid, so hydrolytic process is also purification process, and pure two
Germanium oxide drying is calcined, and obtains germanium metal, semi-conductor industry with hydrogen in 650-680 DEG C of reduction in the quartz ampoule of reduction furnace
HpGe (impurity be less than 1/1010) can obtain by zone refining technology.
The hydrochloric acid of big volume low-concentration can be produced during producing germanium, become a kind of industrial waste acid, it is impossible to be continuing with, process
Cost is high, and environmental protection risk is high.
Summary of the invention
For solve the problems referred to above, the invention provides a kind of produce germanium during low-concentration hcl prepare concentrated hydrochloric acid
Method, carries out reaction generation hydrochloric acid by being passed through chlorine in the environment of heating at dilute hydrochloric acid addition ammonium chloride, so can be effective
Increase dilute hydrochloric acid concentration, with meet to dilute hydrochloric acid again with.
For reaching above-mentioned purpose, the present invention uses techniques below to realize, and during a kind of production germanium prepared by low-concentration hcl
The method of concentrated hydrochloric acid, it is characterised in that: in closing enamel still, it is sequentially added into low-concentration hcl, ammonium chloride solution, to warding off
Porcelain still is passed through chlorine in the case of heating and reacts.
As a further improvement on the present invention, described enamel still top center is provided with motor, and motor lower portion is arranged
Having rotating shaft, be provided with blade bottom rotating shaft, enamel still top left side is provided with air inlet pipe, air inlet pipe outlet be arranged on liquid level with
Under, enamel still left upper portion is provided with inlet, is provided with heating mantle bottom enamel still, and enamel still top right side is provided with gives vent to anger
Pipe, escape pipe connects Drexel bottle, and Drexel bottle top right side is provided with communicating pipe, communicating pipe the other end be provided with gas bomb.
The present invention compared with prior art has the advantages that
1, the Design Conception of the present invention in industry belongs to and proposes first, by the sustained response of ammonium chloride Yu chlorine, increases salt
The concentration of acid, is collected processing to the nitrogen produced simultaneously, has good industrial prospect.
