Problems solved by technology

However, the quality of the anhydrous chloride product obtained by this method is unstable, and when heated in the air by many hydrous chlorides, hydrolysis reactions will occur to generate a large amount of oxides, which will affect the product quality.
It is also possible to directly react the corresponding metal with chlorine to produce anhydrous chloride. This production method is technically feasible, but due to the high production cost, the application of this production method is limited.

Embodiment Construction

[0015] Low-hydrate aluminum chloride (AlCl 3 ·H 2 O-AlCl 3 ·3H 2 O) is a low-water chloride representative, and low-water aluminum chloride (AlCl) containing two water molecules 3 2H 2 O) The fine powder (20μm-1000μm) is sent into the pyrolysis reactor to control the relevant conditions.

[0016] The temperature of the hydrogen chloride synthesis furnace is greater than 400°C, adjust the synthesis amount of HCl gas so that the temperature in the pyrolysis reactor is 188°C, and the pressure on the top of the synthesis furnace is controlled at 0-800mmH 2 O.

[0017] The obtained result of above-mentioned embodiment is as follows:

[0018] 1. The pyrolysis rate of low-hydrate aluminum chloride is greater than 98%

[0019] 2. The content of anhydrous aluminum chloride is greater than 95%

[0020] 3. Hydrochloric acid concentration 31-36%

[0021] 4. There is no gas leakage and no pollutant discharge during the system and production process.

Abstract

The invention discloses a preparing method of waterless chlorinate and industrial alcaine, which comprises the following steps: choosing low chlorinate (MClN.H2O-MClN.3H2O), hydrogen gas and chlorine gas as raw material; using high temperature hydrochloride gas generating by burning hydrogen gas and chlorine gas; carrying low chlorinate into pyrolytic reactor; transferring heat with high temperature hydrochloride gas; generating pyrogenic reactor under the catalysis of electromagnetic wave through the pyrolytic reactor; getting waterless chlorinate and water vapor; entering part gas phase material into hydrochloride synthetic furnace through air-solid segregation; proceeding cyclical usage; displacing left gas phase material into hydrochloride recovery system; getting industrial alcaine. This invention use heat, which is discharged by the react hydrogen gas and chlorine gas possess high effect and quick speed.

Description

technical field [0001] What the present invention relates to is by low water chloride (MCl N ·H 2 O-MCl N ·3H 2 O, wherein M is a metal element, and N is 1 or 2 or 3), hydrogen and chlorine to prepare anhydrous chloride and industrial hydrochloric acid, to be precise, anhydrous hydrochloric acid is prepared by the method of "composite catalytic fluidized pyrolysis" The method for chloride and industrial hydrochloric acid belongs to the fields of fluidized reaction engineering, industrial anhydrous chloride and industrial hydrochloric acid preparation. [0002] Anhydrous chloride is an important fine chemical raw material. There has been no systematic production of anhydrous chloride in China. The research and application of the production of anhydrous chloride from the series chloride system containing water is a blank field in China and even in the world! Background technique [0003] At present, the production method of finding anhydrous chloride on the relevant lite...
