 Ferrous chloride - Synthetic
The most common method is the reaction with iron chloride :
Fe + 2 HCl → FeCl2 + H2
Methanol solution of hydrogen chloride in concentrated hydrochloric
acid as a raw material is more than the simple , solvate reaction
[Fe (MeOH) 6] Cl2, vacuum and heated to about **0 ° C to give pure
FeCl2. [1] FeBr2 and FeI2 similar approach can be taken by the
system .
Besides ferrous chloride and chlorobenzene may also be prepared by
reacting FeCl3 from : [ 2 ] [ 3 ]
2FeCl3 + C6H5Cl → 2FeCl2 + C6H4Cl2 + HCl
Preparation of FeCl2 This is readily soluble in tetrahydrofuran .

iron heating system.
 Ferrous chloride - physical and chemical properties
 Chemical formula FeCl2. Formula weight **6.*5 . Greenish to
yellow . Density 3.*6 g / cm 3 . Melting point ******4 ℃. Before
the boiling point of sublimation. Soluble in water, ethanol and
methanol. There are four water properties FeCl2 · 4H2O, transparent
blue- green monoclinic crystal. Density 1.*3 g / cm 3 .
Deliquescence . Dissolved in water , ethanol , acetic acid,
slightly soluble in acetone, insoluble in ether. Partial oxidation
in the air will become grass green. The air gradually oxidized
alkali chloride -type high-speed rail . Yellow-green anhydrous
ferrous chloride is hygroscopic crystals, dissolved in water to
form a light green solution . Tetrahydrate . When heated to *6.5 ~
C becomes dihydrate .
 Ferrous chloride - Purpose
 Ferrous chloride has a unique bleaching ability for dyes, dye
intermediates, printing and dyeing, paper industry wastewater
treatment . Water treatment technology can simplify and shorten the
treatment period , reduced water treatment costs ; various types of
sewage, electroplating, leather , paper waste a significant
treatment effect, wastewater , sewage removal of heavy metal ions
in various types of close to **0% ; treatment low cost, is the
ideal pharmaceutical wastewater treatment . Directly used for
sewage , wastewater treatment, as a reducing agent and a mordant ,
widely used in textile printing and dyeing, pigment dyeing,
manufacturing and other industries , but also for the high pressure
oil component , is also used in medicine, metallurgy and
photography.
In addition there are the following important purposes:
1, the production of ferric chloride :
The solid ferrous chloride , hydrochloric acid and chlorine gas as
the main raw material to produce ferric chloride , ferrous chloride
of the first ratio to form a solution , heating chlorine gas ,
ferric chloride solution is obtained , if ferric chloride The
solution was filtered , heated , chlorine oxide or nitric acid,
concentrated , cooled, to obtain a solid ferric chloride
hexahydrate . Two complete reaction of ferric chloride into ferric
chloride . Product quality in line with the national standard
GB******9 index .
2, the production of solid polymeric ferric chloride :
(1 ) Ferrous chloride crystals into the reactor , water was added
slowly heated to ****5 ℃, start the reactor stirrer and the
bottom of the reactor through the air , when the temperature to
****5 ℃ stop heating ;
( 2 ) the upper portion of the reactor to the reaction in alkaline
aqueous solution , the reaction liquid under the reaction was added
an aqueous solution of hydrochloric acid to control the temperature
*0 ~ *5 ℃ performed to detect the reactants Fe ↑ [2 +] ≤ 0.*5%
Stop alkali solution was added , the basicity of up to 5 to *0%
aqueous hydrochloric acid was stopped , stirring, into the air
through the hot pressed into the material is cooled to a solid
tableting machine , a high content of the pulverized solid
polymeric ferric chloride , application of the invention produced a
solid polymeric ferric chloride , stable quality, low cost, good
product stability , the production process produces no waste
products are no secondary pollution problems.
3 , the production of ferric chloride flocculant (PAFC):
Aluminum and iron salts with basic flocculant production of an
inorganic polymer flocculant .
4, with ferrous chloride treatment of dyeing wastewater effluent
quality approach:
Methods of quality ferrous chloride treatment of dyeing wastewater.
By adding and changing the polarity of the medium degree of
ionization in the dyeing wastewater with FeCl2. Dyeing wastewater
treatment solution also dyeing wastewater treated with **2 times
the amount of untreated mixed with , and then adjusted to pH
neutralization, coagulation precipitation, solid-liquid separation
emissions of COD removal efficiency ≥ *0%, *0 to *0% color removal
, water does not pan red , wastewater treatment cost savings of
about *0%. FeCl2 is widely used in printing and dyeing wastewater
treatment to create the conditions that can produce good
environmental and economic benefits .
Various types of sewage, electroplating, leather wastewater
treatment has obvious effect , wastewater , sewage removal of heavy
metal ions in various types of close to **0% ; unique bleaching
capacity for dyes, dye intermediates and dyeing industry wastewater
treatment . Water treatment technology can simplify and shorten the
treatment period , reduced water treatment costs.
5 , the production of erasable ink:
The dye is added to a mixture of inorganic salts , the formula is
sodium polyacrylate , ferrous chloride, cobalt sulfate, sodium
sulfate , dye , and water , respectively, of said dye is black ,
blue , green, red and other pigments. The ink used to write the
word ordinary eraser to wipe off easily after writing dry ,
difficult to change, but also the long-term preservation.
6 , pink sediment soil slope fast curing agent:
Ferrous chloride + calcium hydroxide having a large degree of
compression :****0kpa (*8 days) **5 times stronger .
7 , ferrous chloride additives, water mist fire extinguishing
agent:
In order to improve the effectiveness of conventional water mist
fire extinguishing , expanding its scope of application , we use
the method of small -scale experiments to study the Ferrous
Chloride Additives mist fire extinguishing pools at different fuel
types , additive concentration, pressure and effective sex . The
experimental results showed that: a fine mist added to ferrous
chloride , significantly affect its fire performance ; mist
extinguishing quality time with changes in the concentration of
ferrous chloride was added and changed, and there is a minimum fire
time of concentration ; types of work pressure water mist nozzles
and fuel also affects water mist fire suppression performance , the
greater the nozzle operating pressure , the shorter the average
water mist extinguishing time ; under the same experimental
conditions , fine water fog kerosene fire off time is shorter than
the time off ethanol fire .
