Abstract
The invention discloses a zinc selenite production method, which comprises the following steps: step one, 500 to 700 g of selenium dioxide is weighed, added into 1.5 to 2.5 L of water, and stirred to lead the selenium dioxide to be completely dissolved in the water; step two, the selenium dioxide water solution obtained in step one is added with 400 to 500 g of zinc oxide, and is stirred to be completely dissolved; step three, the deposited matter obtained in step two is cleaned, filtered, dried and crushed, and then the zinc selenite product is produced.
Description
Technical field
The present invention relates to a kind of production method of zincium selenious acid.
Technical background
The molecular formula of zincium selenious acid is ZnSeO3, and molecular weight is 192.35; It is a kind of important chemical material, is mainly used in glass industry; Zincium selenious acid is mainly used in discoloring agent, complementary color agent and the releasing agent of all kinds of glass.
The production technique of main zincium selenious acid has zinc carbonate method and chlorination zinc impregnation etc. both at home and abroad at present.
Shortcomings such as the shortcoming that above-mentioned two kinds of common production technique mainly exist is: production cost is higher, and the related equipment of production technique is comparatively complicated, and single complete equipment production capacity is little, and the utilization ratio of raw material zinc is low.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of efficiently, zincium selenious acid production technique cheaply.
For achieving the above object, the present invention has taked following technical scheme:
The production method of zinc selenate is characterized in that comprising following technological step:
(1) take by weighing tin anhydride 500～700g, join in 1.5～2.5L water, stirring makes tin anhydride soluble in water fully;
(2) the tin anhydride aqueous solution that obtains in (1) step adds the zinc oxide of 400～500g, stirs it is reacted completely;
(3) will promptly make the zincium selenious acid product after the washing of precipitate, filtration, oven dry and the pulverizing that obtain in above-mentioned (2) step.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts zinc oxide and tin anhydride as producing former preparation material zincium selenious acid, and production technique of the present invention has that equipment is simple, and single complete equipment production capacity is big, and production cost is low; The advantage of the utilization ratio height of raw material zinc (can reach more than 99%).
