Abstract
The invention provides a kind of is raw material with the thick weisspiessglanz of high arsenic, is auxiliary material with sodium hydroxide, carries out catalysis and oxidizing reaction, thereby produces the novel process of sodium antimonate.This technology comprises add sodium hydroxide solution, thick weisspiessglanz, tartrate and hydrogen peroxide in reactor, through stirring, in the reaction after 3-5 hours down of 40-150 ℃ of normal pressure and temperature, filters, cleans, dry white sodium antimonate.Advantage applies of the present invention reduces significantly at the production cost of sodium antimonate, is swift in response, and product matter is pure.
Description
The invention belongs to the sodium antimonate production technique, it is to be raw material with the thick weisspiessglanz of high arsenic, is auxiliary material with sodium hydroxide NaOH, through catalysis and oxide treatment, produces sodium antimonate.
It is that raw material is made the technology of sodium antimonate and is the technology that raw material is made sodium antimonate with the stibium trioxide that the method for producing at present both at home and abroad sodium antimonate is generally with the antimony sulfide.The former is with HCl and chlorine leaching, through repeatedly getting antimony oxychloride after the hydrolysis, adds the alkali neutralization again and makes sodium antimonate.This method complex process, long flow path, equipment corrosion is serious, waste water treatment difficulty, production cost height, unstable product quality.The latter generally is divided into two kinds, and the technology that provides as the flat 1-278424 of Japanese Patent is, stibium trioxide is dissolved in caustic soda soln, after filtration, adds hydrogen peroxide oxidation again and generate sodium antimonate in filtrate.This method is because stibium trioxide solubleness in caustic soda is very low, thereby direct yield is very low, the production cost height.Another kind is that the production method of raw material production sodium antimonate is to adopt SODIUMNITRATE to make oxygenant to calcine the generation sodium antimonate with soda ash in High Temperature Furnaces Heating Apparatus with the stibium trioxide, this method produces carcinogenic nitrogen dioxide waste gas, equipment complexity, poor product quality, the waste gas pollution control and treatment difficulty, the cost height.
The present invention is intended to overcome the deficiency of aforesaid method, simplifies technology, reduces cost, and improves the output and the quality of sodium antimonate.
Technical solution of the present invention is as follows:
In reactor, add sodium hydroxide solution, stir on the limit, the limit adds thick weisspiessglanz, add winestone acid as catalyst and hydrogen peroxide as oxidant simultaneously, with temperature of reaction control within the specific limits, normal pressure reacted several hours down, and then row filters, clean, after the drying, do not need crystallisation stage, directly get the white products sodium antimonate.In this scheme, except adopting the winestone acid as catalyst, also can adopt tartrate or oxalic acid.Tartrate and tartrate can use separately, also can mix use.The add-on of described three acid is generally the 0.5-10% of thick weisspiessglanz weight.
The embodiment of the invention:
Embodiment
In 1000 milliliters of reactors, inject the sodium hydroxide solution of 300 milliliters of 25-48%, add 150 grams while stirring and contain Sb
2O
394.8% and the thick weisspiessglanz of arsenic 2.7%, adding 7.5 gram tartrate and 160 ml concns simultaneously is the hydrogen peroxide of 27.5-35%, and control reaction temperature react 3-5 hour after-filtration between 65-95 ℃, with the clear water washing, and must the white products sodium antimonate after the drying treatment.This product contains NaSb(OH) 699.12%, contain trivalent antimony 0.09%.
Reaction is undertaken by following formula:
The sodium antimonate that generates is water insoluble, after filtration, washing, the dry white products that gets, impurity arsenic reaction back generates water-soluble sodium arseniate, enters mother liquor, and mother liquid evaporation is got the crystallization sodium arseniate, can be used as glass fining agent.
The thick weisspiessglanz of high arsenic that the present invention adopts is the work in-process of antimony regulus, cost than the stibium trioxide that blows with star metal will be at half, can reduce the production cost of sodium antimonate significantly, but the use accelerated reaction of tartrate or winestone salt, trivalent antimony in the product is dropped to below 0.1%, product color is very white, reacts under normal pressure and can carry out, and need not crystallisation stage.
