Putting the materials into a reaction kettle, and reacting at a certain temperature and pressure, wherein the reaction kettle adopts the following structure: including the cauldron body, the internal baffle that sets up of cauldron, the cauldron body and the cauldron body down are separated into with the cauldron body to the baffle, the baffle exists one at least and can follow cauldron internal wall up-and-down motion, cauldron body upper portion sets up the air inlet, cauldron body lower part sets up the feed inlet. The invention changes the pressure in the reaction kettle by changing the volume of the reaction kettle, and changes the condition that the pressure in the reaction kettle is changed by filling gas in the traditional way.
Description
Technical Field
The invention relates to a synthesis process of hydroxylamine hydrochloride, belonging to the technical field of pesticides.
Background
The hydroxylamine hydrochloride is synthesized under a certain pressure condition, and the pressure condition is usually changed by changing the gas pressure in the reaction kettle in the conventional mode, namely the volume of the reaction kettle is not changed, the pressure in the reaction kettle is changed by charging the gas, the gas consumption is increased firstly, and even if the gas is inert gas, certain treatment is required to be carried out due to factors such as humidity when the gas is extracted after the reaction is finished, so that the improvement is needed.
Disclosure of Invention
The invention aims to overcome the defects and aims to provide a synthesis process of hydroxylamine hydrochloride, which can effectively change the pressure.
The technical scheme adopted by the invention is as follows: the synthesis process of the hydroxylammonium hydrochloride comprises the following steps of putting all materials into a reaction kettle, and reacting at a certain temperature and pressure, wherein the reaction kettle adopts the following structure:
including the cauldron body, the internal baffle that sets up of cauldron, the cauldron body and the cauldron body down are separated into with the cauldron body to the baffle, the baffle exists one at least and can follow cauldron internal wall up-and-down motion, cauldron body upper portion sets up the air inlet, cauldron body lower part sets up the feed inlet.
Further, the partition plate comprises a fixing plate fixedly arranged on the inner wall of the kettle body, the fixing plate is provided with a mounting hole, and a piston is arranged in the mounting hole;
the piston comprises a piston cylinder fixedly arranged in the mounting hole and a piston plate arranged in the piston cylinder, an air pipe is arranged in the kettle body, one end of the air pipe is connected with the air inlet, and the other end of the air pipe is connected to the upper side of the kettle body and communicated with the kettle body; the lower surface of the piston plate is connected with a piston rod, the lower part of the piston rod extends out of the lower part of the kettle body, the lower part of the piston rod is connected with a movable plate which is driven by the piston rod to move up and down, and the movable plate and the inner wall of the kettle body form sealing fit.
Furthermore, a sealing gasket is arranged between the piston and the mounting hole, so that sealing connection is formed between the piston and the mounting hole.
The invention has the advantages that: the invention changes the pressure in the reaction kettle by changing the volume of the reaction kettle, and changes the condition that the pressure in the reaction kettle is changed by filling gas in the traditional way.

Detailed Description
The synthesis process of the hydroxylammonium hydrochloride comprises the following steps of putting all materials into a reaction kettle, and reacting at a certain temperature and pressure, wherein the reaction kettle adopts the following structure:
including the cauldron body, the internal baffle that sets up of cauldron, the cauldron body and the cauldron body down are separated into with the cauldron body to the baffle, the baffle exists one at least and can follow cauldron internal wall up-and-down motion, cauldron body upper portion sets up the air inlet, cauldron body lower part sets up the feed inlet.
Further, the partition plate comprises a fixing plate fixedly arranged on the inner wall of the kettle body, the fixing plate is provided with a mounting hole, and a piston is arranged in the mounting hole;
the piston comprises a piston cylinder fixedly arranged in the mounting hole and a piston plate arranged in the piston cylinder, an air pipe is arranged in the kettle body, one end of the air pipe is connected with the air inlet, and the other end of the air pipe is connected to the upper side of the kettle body and communicated with the kettle body; the lower surface of the piston plate is connected with a piston rod, the lower part of the piston rod extends out of the lower part of the kettle body, the lower part of the piston rod is connected with a movable plate which is driven by the piston rod to move up and down, and the movable plate and the inner wall of the kettle body form sealing fit.
Furthermore, a sealing gasket is arranged between the piston and the mounting hole, so that sealing connection is formed between the piston and the mounting hole.
The invention will be further explained below for a better understanding of the invention: according to the invention, reaction raw materials are injected into the reaction kettle through the feeding hole, when the pressure in the reaction kettle needs to be changed, gas is filled into the gas pipe through the gas inlet and is conveyed into the piston cylinder, and the piston plate pushes the movable plate to move downwards under the pressure, so that the purpose of changing the reaction pressure of the materials is achieved; on the contrary, the movable plate moves upwards by pumping out gas, thereby achieving the purpose of changing the reaction pressure of the materials.
The gas introduced through the gas inlet and the raw materials are not contacted all the time, so that the gas and the raw materials are not influenced mutually, the pressure is changed by changing the volume of the reaction kettle, the original pressure changing mode is changed, and the high-pressure reactor has good service performance.
