Description
Обычно сернистый цинк получают из разбавленных растворов реакгивног-о уксуснокислого цинка путем осаждени цинка очищенным сеооводородом . Полученный продукт загр знен ацетатами и другими соосаждающимис примес ми, от которых он отмываетс со значительными затруднени ми, так как примеси, как правило, заключены внутри 1вердых частиц.Usually, zinc sulphide is obtained from dilute solutions of reactive-zinc acetate by precipitating zinc with purified hydrogen sulfide. The resulting product is contaminated with acetates and other co-precipitating impurities, from which it is washed with considerable difficulty, since impurities are usually enclosed within solid particles.
К тому же, дл этого способа примен етс дорогой реактивный уксуснокислый цинк, аппаратурное оформление процесса очень громоздко , производительность его мала, а услови труда очень т желы.In addition, expensive reactive zinc acetate is used for this method, the instrumentation of the process is very cumbersome, its productivity is low, and the working conditions are very heavy.
Предложенный новый способ получени сернистого цинка взаимодействием окиси цинка (цинковых белил) с сернистым аммонием, свободный от вышеперечисленных недостатков, заключаетс в том. что дл повышени качества целевого продукта и ускорени процесса осаждени его ведут в присутствии катализаторов - ацетатов аммони .The proposed new method for producing zinc sulphide by reacting zinc oxide (zinc oxide) with ammonium sulphide, free from the above disadvantages, is that. to improve the quality of the target product and accelerate the deposition process, it is carried out in the presence of ammonium acetate catalysts.
При получении ZnS по описанному способу предотвращаетс соосаждение примесей и в качестве сырь примен ютс общедоступные и дешевые сернистый аммоний и цинковые белила, выпускаемые в крупнопромышленном масштабе.In the preparation of ZnS by the described method, the coprecipitation of impurities is prevented and the quality of the raw material is the generally available and cheap ammonium sulphide and zinc white, produced on a large industrial scale.
Отличительной особенностью описываемого способа вл етс то, что продукт получают путем хемосорбции сульфидной серы в присутствии катализатора ацетата аммони . Механизм воздействи ацетата аммони заключаетс в следуюшгем.A distinctive feature of the described method is that the product is obtained by chemisorption of sulfide sulfur in the presence of an ammonium acetate catalyst. The mechanism of action of ammonium acetate is as follows.
