Production of copper acetate

Abstract

Production of cupric acetate is carried out by filling tower body with copper fillings, pouring cupric acetate mother liquid into tower base, circulation spraying for mother liquid by circulation pump, entering oxygen into junction of tower body and tower kettle, injecting running mother liquid into crystallizer, crystallizing, delivering the product into crystallizing filter, crystallizing, mother liquid separating, putting the separated acetate crystallization into drier, drying, putting the separated mother liquid into store tank, storing, adding into glacial acetic acid by additive metering vessel, adjusting radical acetic acid concentration in mother liquid, verifying and packing. It is high efficient and non-toxic. It can be used for insecticide, ceramic blended oil, catalyst and bactericide in green pesticide.

Description

technical field [0001] The present invention relates to the production method of a kind of chemical product used for bactericide, especially relate to the technical improvement of a kind of copper acetate production process. Background technique [0002] Copper acetate, molecular formula: Cu(CH 3 COO) 2 ·H 2 O, also known as copper acetate, is also called hydrated copper acetate because it contains 1 crystal water. [0003] Copper acetate products seen in the domestic and international chemical market, its traditional industrial production method is to use copper sulfate and copper carbonate as raw materials, first react to generate copper carbonate, then add acetic acid to convert into copper acetate. But this traditional process method has two shortcomings that are difficult to overcome: one is that sodium sulfate is produced at the same time when copper carbonate is generated. Sodium is washed, thereby operation is loaded down with trivial details, and labor cost is h...

Problems solved by technology

But this traditional process method has two shortcomings that are difficult to overcome: one is that sodium sulfate is produced at the same time when copper carbonate is generated. Sodium is washed, thereby operation is loaded down with trivial details, and labor cost is higher, also brings environmental pollution problem; The 2nd, the aqueous solution of the copper acetate crystallization that this method obtains is turbid, opaque, why can be like this, reason is that the copper acetate crystallization contains fine For water-insoluble copper carbonate particles, recrystallization is required to solve the serious excess of water-insoluble matter, but this will make the process more complicated, the unit consumption of acetic acid will increase significantly, and the energy consumption will be serious
