Abstract
The invention relates to the chemical engineering field, in particular to an ammonium sulfide solution and a production process thereof. The content of ammonium sulfide in the ammonium sulfide solution is 10 percent to 45 percent. The ammonium sulfide solution and the production process have the advantages of strong stability and unchanged concentration and is deposit-free, and the color of the ammonium sulfide solution cannot be changed within a year.
Description
Technical field
The present invention designs chemical field, and a kind of ammonium sulfide solution and complete processing thereof specifically are provided.
Background technology
Ammonium sulfide solution under the prior art generally just adopts hydrogen sulfide and ammonia chemical combination and blends, but its concentration of the ammonium sulfide solution that this mode obtains is lower, it is very easily variable color and reduce concentration under long-term situation of placing, thereby influence its normal use, make troubles for manufacturer and user.
Summary of the invention
The present invention be directed to above deficiency, a kind of ammonium sulfide solution and complete processing thereof are provided, its product stability is strong, nondiscoloration in a year, and sediment-free and concentration are constant.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of ammonium sulfide solution, the content of ammonium sulfide is 10%-45% in the described ammonium sulfide solution.
A kind of complete processing of ammonium sulfide solution may further comprise the steps:
A, sodium sulphite and sulfuric acid are reacted the formation hydrogen sulfide;
B, will liquefied ammonia filter the back and form ammoniacal liquor with the water reaction;
C, the hydrogen sulfide that generates dashed described ammoniacal liquor after filtering converts, towards the time of converting be 56-200 hour, thereby form described ammonium sulfide solution.
A kind of ammonium sulfide solution of the present invention and production technique thereof, its product is stable, stores the look that can remain unchanged for a long time in the lucifuge bucket, and concentration is kept stable, sediment-free.
Whole process using reagent standard in the production technique of the present invention, thus the stability and the security of product greatly increased.
Embodiment
Below in conjunction with specific embodiment a kind of ammonium sulfide solution of the present invention and complete processing thereof are further described.
A kind of ammonium sulfide solution, the content of ammonium sulfide can be 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% in the described ammonium sulfide solution.
The complete processing of above-mentioned a kind of ammonium sulfide solution may further comprise the steps:
A, sodium sulphite and sulfuric acid are reacted the formation hydrogen sulfide;
B, will liquefied ammonia filter the back and form ammoniacal liquor with the water reaction;
C, the hydrogen sulfide that generates dashed described ammoniacal liquor after filtering converts, towards the time of converting be 56-200 hour, thereby form described ammonium sulfide solution.
A kind of ammonium sulfide solution of the present invention, the height of its content determines that according to the time it is high more towards the time concentration of converting of a specified duration more.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
Claims (2)
1, a kind of ammonium sulfide solution is characterized in that, the content of ammonium sulfide is 10%-45% in the described ammonium sulfide solution.
2, a kind of complete processing of ammonium sulfide solution is characterized in that, may further comprise the steps:
A, sodium sulphite and sulfuric acid are reacted the formation hydrogen sulfide;
B, will liquefied ammonia filter the back and form ammoniacal liquor with the water reaction;
C, the hydrogen sulfide that generates dashed described ammoniacal liquor after filtering converts, towards the time of converting be 56-200 hour, thereby form described ammonium sulfide solution.
