Embodiment Construction

[0016] Low-hydrate cobalt chloride (CoCl 2 2H 2 O) The fine powder (20μm-500μm) is sent into the pyrolysis reactor to control the relevant conditions.

[0017] The temperature of the hydrogen chloride synthesis furnace is greater than 500°C, adjust the synthesis amount of HCl gas so that the temperature in the pyrolysis reactor is 238°C, and the pressure on the top of the hydrogen chloride synthesis furnace is controlled at 0-1000mmH 2 O.

[0018] The obtained result of above-mentioned embodiment is as follows:

[0019] 1. The pyrolysis rate of low-water cobalt chloride is greater than 98%

[0020] 2. The content of anhydrous cobalt chloride is greater than 95%

[0021] 3. Hydrochloric acid concentration 31-36%

[0022] 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 with low water cobalt chloride (CoCl2.H2O-CoCl2.3H2O), hydrogen gas and chlorine gas as raw material, which comprises the following steps: 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.

Description

technical field [0001] What the present invention relates to is by low water cobalt chloride (CoCl 2 ·H 2 O-CoCl 2 ·3H 2 (O), hydrogen and chlorine prepare the method for anhydrous cobalt chloride and industrial hydrochloric acid, to be precise is the method for preparing anhydrous cobalt chloride and industrial hydrochloric acid with the method of " composite catalytic fluidized pyrolysis ", belongs to fluidization Reaction engineering, preparation of industrial anhydrous cobalt chloride and industrial hydrochloric acid. [0002] Anhydrous cobalt chloride is a fine chemical raw material. There has been no large-scale production of anhydrous cobalt chloride in China. The research on the production of industrialized anhydrous cobalt chloride has always been valued by my country's chemical industry. Background technique [0003] At present, the production method of finding anhydrous cobalt chloride on the relevant literature is mainly cobalt chloride hexahydrate (CoCl 2...
