Abstract

PURPOSE:To prepare aluminum chloride safely at a low cost, by utilizing a waste material of vinyl chloride or chlorinated paraffin as a chlorine source in preparing the aluminum chloride. CONSTITUTION:A waste PVC or chlorinated paraffin disused in a factory and aluminum are charged into a reactor and heated in an atmosphere containing no oxygen. The polyvinyl chloride and chlorinated paraffin are thermally decomposed into hydrogen chloride and carbon, and the hydrogen chloride is reacted with the aluminum to form aluminum chloride. There is no fear of danger for the leakage of chlorine gas leakage since chlorine gas is not used, and the preparation cost is low due to the use of the waste materials, e.g. polyvinyl chloride, as the chlorine source. The carbon generated at the same time as a by-product is utilizable as a raw material for active carbon.

Description

[Detailed Description of the Invention] A method for manufacturing Al 1 (V) that lacks safety due to the use of toxic chlorine scum, and therefore has the disadvantage of causing anxiety when removing the scum. In addition to eliminating the above drawbacks, we used vinyl chloride, which was recovered as waste or was no longer used in factories, as a substitute for chlorine, and removed it from the carbonaceous residual oil. The present invention is aimed at increasing the possibility of significantly lowering the IJt cost, and the present invention does not involve reacting with the boundary f-binyl or sulfurized paraffin and alkaline metal in a zero atmosphere. According to the conventional method for producing aluminum chloride, aluminum is added in the presence of air, the fC reaction is heated, and then chlorine is blown into the aluminium, which is then heated. In contrast to the stiffness that would have been obtained by using a cooler connected to one reactor with enriched aluminum containing #!lt, the present invention uses chloride instead of sludge and chlorine. Put the vinyl or overlying paraffin and aluminum into a reactor, exchange the internal air with a phonogen, etc. to create an oxygen-free atmosphere, and then heat it to form aluminum chloride into a cooling liquid.II! In the case of vinyl chloride, the reaction formula is as follows.

3 I Bekot Yasumo) / Shito O 1 l This 1 Salt without interruption. Vinyl chloride thermally decomposes in unextracted inebriated air at around 300°0, producing hydrogen chloride! , after the formation of an element, there is one reaction between Al 1=um and hydrogen chloride, which is an exothermic reaction.
The sulfur which is chemically formed in the octopus reaction can be used as a raw material for the production of active fibers. Note that the reaction of chlorinated paraffin is also -1 the same as that of vinyl chloride, so the term fjA is omitted.
The inside of the reactor is oxygen-free and has zero atmosphere. If air exists, the hydrogen chloride generated near 30 d'o will not react with aluminum, and it must be heated to over VrsoO°0. , the generated carbon combusts late around sod'o. Therefore, it is not possible to produce aluminum chloride unless the atmosphere is replaced with nitrogen during the reaction.In addition, hydrogen chloride is generated.Vinyl chloride and chlorinated paraffin, which are used as waste materials, are used for disposal. Even if it is hot, it will not interfere with the production of aluminum chloride (= rum).

Next, an example of this production method will be explained. was put into the reaction, the internal air was replaced with nitrogen, and the reactor was heated after 7 tons. When the temperature reaches about aoO°OK, the hydrogen chloride generated from vinyl chloride reacts with aluminum and condenses it into a reaction @, producing 1 = 1 aluminum chloride. Since the reaction is exothermic, the heating temperature should be kept at SOO "0" (,
In addition, the slag-like residue generated at the bottom of the reactor is used as a raw material for activated carbon.Thin plate aluminum cut into a size suitable for 9nC and waste mulberry *chlorinated paraffin are put into the reactor. The internal air is heated with nitrogen and then heated. When it reaches about 300°C, the hydrogen chloride generated from the chlorine paraffin reacts with the hydrogen chloride to form aluminum chloride. The negative condensation is applied to the cooling system.

Since the reaction is a total heat reaction, one wrinkle that can maintain approximately so, 00c is sufficient for heating.Patent Ratio - Person Ministry of Labor Child Work Safety Research Institute Director Procedural Amendment Letter 1978 Birth Sep 19 National License Agency Nagatomi Shimada Mr. Haruki JL @ Those who make corrections false substitutes All + correct objects jllaltf) Inventor's column (2F) I submitted an amendment that corrected the entire specification as the 8th item asa116aJ of the correction ( 2) Correct the entire statement as follows: List of attached documents ill fl Original copy J1 copy (2) Certificate of residence 1 copy (s) Certificate of absence

Along with eliminating the drawbacks of the original Wi4tff! IC1
In addition to using chlorinated paraffin in vinyl chloride, which is collected as waste or unused in factories, as a chlorine source, we also measure the carbonaceous residue generated during the reaction in oil, which reduces production costs. Thus, the present invention consists in reacting vinyl chloride or chlorinated paraffin with aluminum in an oxygen-free atmosphere.

The traditional method for producing aluminum chloride involves heating a reactor tube containing aluminum in the presence of air.

Next, the aluminum chloride produced by blowing in chlorine is cooled in a cooler installed in a double reactor I/R tank. Bamboo chlorinated paraffin and aluminum are placed in a reactor, the internal air is replaced with nitrogen, etc. to make oxygen-free gas, and then heated.This is a reaction method that causes aluminum chloride to be produced in a cooler from K. is as follows in the case of vinyl chloride. 30zByOL+AL-+A LO

It thermally decomposes in an acid-free atmosphere near fa to produce hydrogen chloride and carbon. Hydrogen chloride immediately reacts with aluminum to produce aluminum chloride, which is an exothermic reaction. The carbon produced can be used as a raw material for producing activated carbon. Note that WiwA is omitted because the reaction of chlorinated paraffin is the same as that of vinyl chloride.

The feature of the method for producing aluminum chloride that takes advantage of this reaction is that one reactor is surrounded by an oxygen-free atmosphere, and if air is present, the hydrogen chloride generated near soo@o will react with aluminum. It then ignites and burns at 300'O*il. Therefore, aluminum chloride cannot be produced unless the air in the reactor is replaced with nitrogen. Even if vinyl chloride and chlorinated paraffin, which are the raw materials for producing hydrogen chloride, are wastes that require incineration, they cannot be used in the raw production of aluminum chloride. A thin plate of aluminum cut to an appropriate size and waste vinyl chloride crushed to an appropriate size were placed in a reactor, and the internal air was replaced with nitrogen. Heat later for about 300'
When OK is reached, hydrogen chloride generated from vinyl chloride reacts with aluminum to produce aluminum chloride, which is sent to the reactor. Since the reaction is an exothermic reaction, the heating need only be maintained at about 300°0, and the carbonaceous residue tJIk produced at the bottom of the reactor can also be used as a raw material for activated carbon.

Implementation ipHj21 Thin plate aluminum cut to an appropriate size and waste chlorinated paraffin are placed in a reactor, and the internal air is flushed with nitrogen.
When the temperature reaches about 30 DDK, it reacts with the hydrogen chloride lamp aluminum generated from the chlorinated paraffin to produce aluminum chloride. Since the reaction that would cause the condenser to flow into the condenser attached to the reactor is an exothermic reaction, 1 is sufficient to maintain the heating temperature at about 3009C.
