Technical Field
The invention relates to the field of inorganic chemical industry, in particular to a method for preparing sodium bisulfate.
Background
Sodium bisulfate is an important inorganic chemical product, can be used as a cosolvent, a dyeing assistant, a disinfectant, a preservative, a cleaning agent and a catalyst, and can be used for preparing sulfate, sodium alum and the like.
The preparation method of the sodium bisulfate mainly comprises the following steps:
sodium hydroxide and sulfuric acid are used as raw materials. The reaction principle is as follows:
NaOH+H2SO4→NaHSO4+H2O
sodium sulfate and sulfuric acid are used as raw materials. The reaction principle is as follows:
Na2SO4+H2SO4→2NaHSO4
sodium chloride and sulfuric acid are used as raw materials. The reaction principle is as follows:
NaCl+H2SO4→NaHSO4+HCl
these methods all use strong acid and strong base, and are very corrosive to equipment.
Disclosure of Invention
The invention provides a method for preparing sodium bisulfate, which aims to solve the problem that strong acid and strong base are adopted during the preparation of sodium bisulfate in the prior art, so that equipment is seriously corroded.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: sodium thiosulfate or sodium bisulfite is used as a raw material, and hydrogen peroxide is used as an oxidant to prepare sodium bisulfate through oxidation-reduction reaction.
The reaction principle is as follows:
Na2S2O3+4H2O2→2NaHSO4+3H2O
NaHSO3+H2O2→NaHSO4+H2O
further, the method of the invention adopts the following specific steps:
hydrogen peroxide was added to a round bottom flask equipped with a reflux condenser and a constant pressure dropping funnel. Dissolving sodium thiosulfate or sodium bisulfite in water to obtain a solution. Sodium thiosulfate or sodium bisulfite solution was added dropwise to the flask with stirring.
When the raw material is sodium bisulfite, the obtained reaction solution is poured into an evaporating dish, is put on a boiling water bath for evaporation, is concentrated until no bubbles are generated, is put into a drier for cooling to room temperature, and is transferred into a container for sealed storage.
When the raw material is sodium thiosulfate, the obtained reaction solution is heated on a boiling water bath for 1 hour, cooled to room temperature, filtered, taken out, poured into an evaporating dish, placed on the boiling water bath for evaporation, concentrated until no bubbles are generated, and then placed into a dryer for cooling to room temperature. And (4) moving the product into a container for sealing and storing.
In the specific steps, the reaction liquid is evaporated on a boiling water bath, and the concentration degree is bubble-free, which is the key point of the method of the invention, and the collected sodium bisulfate has high yield and high content. In addition, the order of adding the sodium thiosulfate or sodium bisulfite solution to the hydrogen peroxide solution is also critical in the preparation method.
Preferably, the sodium thiosulfate or sodium bisulfite solution is dripped into the hydrogen peroxide solution in a stirring and dripping manner, the dripping speed is 1 drop in 4-5 seconds, and stirring is continued for 10 minutes after dripping is finished.
Further, the mass ratio of hydrogen peroxide to sodium thiosulfate used is greater than 4: 1.
Further, the amount of hydrogen peroxide to sodium bisulfite used is greater than 1: 1.
Compared with the prior art, the invention has the following beneficial effects:
the raw materials adopted by the method are sodium thiosulfate or sodium bisulfite which is common inorganic salt and has no corrosiveness, and the hydrogen peroxide is an environment-friendly clean oxidant, so that the corrosion of equipment caused by strong acid and strong alkali is avoided.
Detailed Description
The present invention is further illustrated by the following specific examples.
Example 1
A50 mL round-bottom flask equipped with a water bath, reflux condenser and constant pressure dropping funnel was charged with 10mL of 30% by mass hydrogen peroxide. Weighing 4.9767gNa2S2O3·5H2O was dissolved in 10mL of deionized water to make a solution. Starting stirring, dropwise adding the sodium thiosulfate solution into the flask at the speed of 1 drop every 4-5 seconds, and continuing stirring for 10 minutes after the addition is finished. Heat in a boiling water bath for 1 hour. Cooled to room temperature and filtered with suction. The filtrate is poured into an evaporating dish inEvaporating on boiling water bath, and concentrating until no bubbles are generated. The mixture was cooled to room temperature in a desiccator. Weighed to give 5.1334g of colorless crystals in 92.70% yield (in NaHSO)4·H2And O is calculated). The content of NaHSO is determined according to HG/T4516-4·H2The O content was 98.58%.
Example 2
A50 mL round-bottom flask equipped with a reflux condenser and a constant pressure dropping funnel was charged with 6mL of 30% by mass hydrogen peroxide. Weighing 5.2154g NaHSO3Dissolved in 10mL of deionized water to prepare a solution. Starting stirring, dropwise adding the sodium bisulfite solution into the flask at the speed of 1 drop every 4-5 seconds, and continuing stirring for 10 minutes after the addition is finished. Pouring the reaction solution into an evaporating dish, evaporating on a boiling water bath, and concentrating until no bubbles are generated. The mixture was cooled to room temperature in a desiccator. Weighed to give 6.5066g of colorless crystals, yield 94.02% (as NaHSO)4·H2And O is calculated). The content of NaHSO is determined according to HG/T4516-4·H2The O content was 91.16%.
