Abstract
A kind of method of utilizing the pharmaceutical industry waste manganese slag to produce activated manganese dioxide, it relates to chemical sludge and utilizes the field.It is characterized in that it is a raw material with the waste manganese slag of pharmaceutical industry and acid and water, makes activated manganese dioxide by six procedures such as roasting, acidifying, separation, activation, pulverizing.
This method turns waste into wealth, the protection environment; Cost is low, and the profit height has competitive capacity.
Description
The present invention belongs to chemical sludge and utilizes the field for a kind of method of utilizing the pharmaceutical industry waste manganese slag to produce activated manganese dioxide.
Existing method of producing artificial Manganse Dioxide mainly contains following three kinds: a, electrolytic process; The air oxidation process of b, the low manganese of oxidation; C, higher-grade manganese ore are sintered into manganic oxide acid wash again.Mainly there are the following problems for above method: a method cost height, and energy consumption is big, and the production cycle is long, and facility investment is big; B method cost height, active inhomogeneous, oxidation is difficult to control; C method raw material is day by day exhausted, can not form industrial production.Immediate with the present invention is the c method.
How to utilize the waste manganese slag of pharmaceutical industry to produce activated manganese dioxide, turn waste into wealth, the protection environment, day by day withered thirsty to alleviate current higher-grade manganese ore, the high reactivity manganese present situation that supply falls short of demand is an aim of the present invention.
Main technical schemes of the present invention is: it is a raw material with the waste manganese slag of pharmaceutical industry and acid and water, makes activated manganese dioxide by six procedures such as roasting, acidifying, separation, washing, activation, pulverizing.
This method also can be reduced to acidifying, separation, washing, activation, pulverizing five processes with original six procedures according to the require situation of user to product, promptly saves this procedure of roasting.This method also can increase before roasting or acidifying washes pretreatment process together.
The raw materials used production medicine intermediate TMP(trimethylammonium benzylamine pyrimidine that can be of this method) waste manganese slag that produces in the process.
The invention has the advantages that: main raw material is cheap, turns waste into wealth the protection environment; Technology is simple, grasps easily; Reduced investment, instant effect, cost is low, the profit height.
Be described in further detail below:
Fig. 1 is a technological process block-diagram.
Fig. 2 is the examination and test of products differential thermal curve figure by method-production.
The related several concepts of elder generation's herein interpreted:
Manganese slag: refer in particular to the waste manganese slag that pharmaceutical industry produces. As produce medicine intermediate TMP(benzyl trimethyl ammonium pyrimidine) time manganese slag that produces. The main component of this manganese slag is brown manganese dioxide, also contains manganese salt and other impurity of other valence state.
Acid: refer to sulfuric acid, nitric acid and corresponding spent acid, its concentration range is: sulfuric acid 5-98%, nitric acid 5-67%.
Alkali: a class alkali that can generate with the inorganic acid effect salt soluble in water.
Method one
1, acidifying: waste manganese slag, acid, water are added acid wash drum by a certain percentage, pickling certain hour in the time of 60-100 ℃.
2, separate: the solution after the acidifying is carried out solid-liquid separation.
3, washing: the manganese slag after will separating washes with water for several times, until cleaning.Wherein if contain that excess acid can add in the alkali and after washing again, make product acidity be controlled at PH4-7.
4, activation: the manganese slag after will cleaning activates a few hours 80-350 ℃ of oven dry.
5, pulverize: the product after will drying, activating is the activated manganese dioxide finished product by customer requirements pulverizing, packing.
Method two
1, roasting: with the manganese slag at 500-800 ℃ of roasting certain hour.
2, manganese slag after the roasting is got final product by " 1,2,3,4,5 " in the method one.
Illustrate:
1, can earlier raw material manganese pulp water be washed, carry out pre-treatment, then by method one or method two production.
2, the product physical and chemical performance produced of method one, two with pickling, activation temperature is different and different, can select corresponding conditions production by customer requirements.
3, during excess acid, can add the alkali neutralization in washing earlier, again the salt that generated of flush away neutralization reaction.
The main chemical equation that aforesaid method is related
Method one:
Method two
In and excess acid:
Oven dry, activation:
Embodiment
Method one
1, takes by weighing 1000g Western medicine intermediate waste manganese slag that TMP produces (in dry product), measure 98% vitriol oil 60ml(220ml), water 4000ml(3000ml), the acid-washing stainless steel bucket that places band to stir, warming while stirring reaches 65 ± 2 ℃ (95 ± 2 ℃), insulated and stirred for some time.
2, make solid-liquid separation with vacuum filtration.
3, the manganese slag after will separating adds hot water 5000ml(8000m), in stainless steel cask, stir evenly, solid-liquid separation repeats to make product acidity reach PH5(PH7 for several times again).
4, Xi Hao manganese slag at 200 ± 2 ℃ of (350 ± 2 ℃) freeze-day with constant temperature, activates four to eight hours in drying baker.
5, thing section is ground, sieving is the finished product activated manganese dioxide.
Method two
1, take by weighing waste manganese slag 500g, take 550 ± 2 ℃ of (750 ± 2 ℃) roasting 2(4 in the stove in horse) hour.
2, the manganese slag after the roasting is finished product by " 1,2,3,4,5 " in the above method one processing.
Annotate: each embodiment all does second trial, test conditions unbracketing for the first time, the data in the bracket be the control reaction conditions of test for the second time, do not give dated all with the first time test conditions identical.
The description of product:
Activated manganese dioxide is a black crystals, and molecular formula is MnO
