Abstract
The invention relates to chemical experiment equipment, and in particular discloses a chloroazotic acid preparation device. The chloroazotic acid preparation device comprises a reagent bottle with three openings, and is characterized in that a liquid inlet pipe is arranged at a bottleneck in the top end of the reagent bottle and is connected with a U-shaped pipe through a valve; two branch pipelines of the U-shaped pipe are connected in parallel with the liquid inlet pipe; furthermore, series ball-shaped liquid storage pipes with corresponding positions are respectively arranged on the two branch pipelines; the volume ratio of the ball-shaped liquid storage pipes on the two branch pipelines is 3 to 1; volume calibration lines are arranged on the branch pipelines. The chloroazotic acid preparation device is simple in structure and convenient to use; product preparation is quick and safe; the whole operation is realized in a closed environment; volatilization of raw materials and a product in a measuring process is effectively prevented; the cleanness of the environment and the health of a human body can be protected, and the chloroazotic acid preparation device is suitable for being widely popularized and applied.
Description
(1) technical field
The present invention relates to a kind of equipment of chemical industry, particularly a kind of chloroazotic acid device for formulating.
(2) background technology
Chloroazotic acid, also known as king's acid, nitrohydrochloric acid, the liquid that a kind of corrosivity is very strong, emit yellow cigarette, it is the mixture of nitric acid and hydrochloric acid composition, wherein mixed proportion is 1:3(volume ratio), having than red fuming nitric acid (RFNA) or the more strong corrosiveness of concentrated hydrochloric acid, is that minority can dissolve one of material of gold and platinum.
In prior art, the preparation of chloroazotic acid is generally add in mixing arrangement to stir after red fuming nitric acid (RFNA) and concentrated hydrochloric acid being measured respectively by pipette to obtain, because red fuming nitric acid (RFNA), concentrated hydrochloric acid and last product chloroazotic acid all have very strong volatilization and corrosivity, operate very inconvenient, and carry out travelling backwards liquid and measure to waste time and energy, raw material is easily polluted in operation, and damage human body because operating procedure is too much easy, severe patient can be lethal simultaneously.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the chloroazotic acid device for formulating that a kind of structure is simple, easy to use.
The present invention is achieved through the following technical solutions:
A kind of chloroazotic acid device for formulating, comprise the reagent bottle arranging three mouthfuls, it is characterized in that: the top bottleneck of described reagent bottle is provided with feed tube, feed tube connects U-tube by valve, two branch pipeline of U-tube are connected in parallel feed tube, and two branch pipeline are respectively arranged with the spherical liquid storage pipe of series connection corresponding to position, the volume ratio of the spherical liquid storage pipe in two branch pipeline is 3:1, and branch pipeline is provided with volume calibration line.
When the present invention prepares according to chloroazotic acid, the volume ratio of nitric acid and hydrochloric acid is the feature of 1:3, be provided with the U-tube connecting reagent bottle, U-tube is arranged the spherical liquid storage pipe that volume ratio is 3:1, hydrochloric acid and nitric acid is held respectively in two branch pipeline of U-tube, and pass through the release of raw material in Valve controlling branch pipeline, the material quantity added is demarcated, is convenient to the purity and the quality that ensure product.
More excellent scheme of the present invention is:
In view of the effumability of raw material and product, in the both sides mouth of described reagent bottle, a side mouth is provided with the offgas duct connecting device for absorbing tail gas, another side mouth is provided with stopper, by the gas volatilized in device for absorbing tail gas absorption reagent bottle, prevent the injury of pollution to surrounding environment and human body.
Described reagent bottle is placed on magnetic stirring apparatus, is realized the rapid mixing of the raw material entered in reagent bottle by magnetic agitation.
Be provided with liquid outlet bottom described reagent bottle, by liquid outlet, the chloroazotic acid be mixed to get outwards discharged, so that use in time.
The branch pipeline top mouth of pipe of described U-tube is uncovered, and the mouth of pipe is provided with grinding port plug, carries out airtight depositing, prevent it from volatilizing to the red fuming nitric acid (RFNA) in U-tube and concentrated hydrochloric acid.
Structure of the present invention is simple, easy to use, and fast and safely, whole operation is in airtight environment to product configuration, effectively prevent raw material and the volatilization of product in the process of measuring, and is convenient to protection of the environment and cleans and health, be suitable for wide popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 reagent bottle, 2 feed tubes, 3 U-tube, 4 spherical liquid storage pipes, 5 volume calibration lines, 6 device for absorbing tail gas, 7 offgas duct, 8 stoppers, 9 magnetic stirring apparatus, 10 liquid outlets, 11 grinding port plugs.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises the reagent bottle 1 arranging three mouthfuls, the top bottleneck of described reagent bottle 1 is provided with feed tube 2, feed tube 2 connects U-tube 3 by valve, two branch pipeline of U-tube 3 are connected in parallel feed tube 2, and two branch pipeline are respectively arranged with the spherical liquid storage pipe 4 of series connection corresponding to position, the volume ratio of the spherical liquid storage pipe 4 in two branch pipeline is 3:1, and branch pipeline is provided with volume calibration line 5; In the both sides mouth of described reagent bottle 1, a side mouth is provided with the offgas duct 7 connecting device for absorbing tail gas 6, another side mouth is provided with stopper 8; Described reagent bottle 1 is placed on magnetic stirring apparatus 9; Liquid outlet 10 is provided with bottom described reagent bottle 1; The branch pipeline top mouth of pipe of described U-tube 3 is uncovered, the mouth of pipe is provided with grinding port plug 11.
With the volume calibration line 5 in branch pipeline in U-tube 3 for benchmark, concentrated hydrochloric acid is injected toward having in the branch pipeline of the spherical liquid storage pipe 4 of larger volume, red fuming nitric acid (RFNA) is injected in another branch pipeline, in reagent bottle 1, the concentrated hydrochloric acid and red fuming nitric acid (RFNA) that volume ratio is 3:1 is put into respectively by the control of valve, open magnetic stirring apparatus 9 to stir, obtain product chloroazotic acid, the tail gas discharged in reagent bottle 1 enters device for absorbing tail gas 6 by offgas duct 7 and processes.After chloroazotic acid prepares, by the end sealing of grinding port plug 11 by U-tube 3 liang of branch pipeline, prevent the volatilization of acid; When needs chloroazotic acid, open the stopper 8 on the mouth of reagent bottle 1 side, outwards discharge chloroazotic acid from liquid outlet 10, be convenient to use.
