Embodiment 1

[0011] Embodiment 1: In this embodiment, formic acid and potassium hydroxide are used as raw materials. First, solid flake potassium hydroxide is added to the reactor from the feed port of the reactor, and then the reactor cooling water circulation system is opened to control the reaction in the reactor. The temperature at time, then the metered formic acid is added in the reactor from the top of the reactor, the amount of formic acid and potassium hydroxide addition is the proportioning of its molecular weight ratio. Such as: the molecular weight ratio of formic acid and potassium hydroxide is 46:56, the content of formic acid is 85%, and the content of potassium hydroxide is 94%, then the addition amount of formic acid and potassium hydroxide is 1:1.1, that is, add Content is 1.1 tons of potassium hydroxide of 94%, proportioning adding content is 1 ton of formic acid of 85%, after adding formic acid, start the stirrer of reactor, adjust the flow of cooling water, control the ...

Embodiment 2

[0012] Embodiment 2: present embodiment is that formic acid and salt of wormwood are main raw materials to produce potassium formate, and its technical process is basically the same as embodiment 1, because the molecular weight ratio of formic acid and salt of wormwood is 92: 138; Its content of the formic acid of use is 85%, and the addition amount is 1 ton; the content of potassium carbonate is 98%, and the addition amount is 1.3; first, potassium carbonate is added to the reactor from the feeding port of the reactor, and the cooling water circulation system is opened, and then formic acid is added from the top of the reactor. , start the agitator, adjust the flow of cooling water, control the reaction temperature in the reactor to be 50 ± 2 ° C, open the reactor pressure control valve, make the pressure in the reactor be normal pressure, after the reaction is completed to prepare potassium formate, put Potassium formate is sent into the evaporator, the temperature inside the...

Abstract

The method for producing potassium formate uses formic acid and potassium hydroxide or potassium carbonate as raw material, and includes the following steps: adding the above-mentioned raw materials into a reactor, stirring, controlling reaction temp. to obtain potassium formate, feeding the obtained potassium formate into evaporator and evaporating the water formed by producing potassium formate, and making the potassium formate into melt state so as to obtain finished product.

Description

1. Technical field [0001] The invention is a method for producing a new fine chemical material "potassium formate". 2. Background technology [0002] Potassium formate is a downstream product of formic acid. It is mainly used as an additive in drilling fluid for oil production. Adding potassium formate to drilling fluid can achieve high density and maintain low viscosity, prevent blowout, increase drilling speed, and prolong the use of drill bits. life. The role of reducing mining costs. It can also be widely used in road construction, especially in expressway construction. As an antifreeze agent in winter construction, it has a good antifreeze effect; it can also be used in airports, etc., and can replace sodium chloride to melt snow in snowy days. Does not pollute the environment, etc. [0003] At present, due to its complex manufacturing process, high production cost and high technical difficulty, there is no production of potassium formate in my country, and only a fe...
