Zinc Chloride
General InformationZinc chloride is the name of
chemical compound with the formula
ZnCl2
and its hydrates. ZnCl2, of which nine crystalline forms are known, is colorless
or white and highly soluble in water. ZnCl2
itself is hygroscopic and even deliquescent.
Samples should therefore be protected from sources of moisture, including the
water vapor present in ambient air. ZnCl2 finds wide application in textile processing,
metallurgical fluxes,
and chemical synthesis. No mineral with this chemical composition as
ZnCl2 is known although a very rare mineral, simonkolleite, Zn5(OH)8Cl2H2O
is known.
Applications & Uses:

As a metallurgical flux
Zinc chloride has the ability to
attack metal oxides (MO) to give derivatives of the formula
MZnOCl2. This reaction is relevant to
the utility of ZnCl2
as a flux for soldering. It is used
in fluxes for galvanizing, soldering and tinning.


In organic synthesis
In the laboratory, it finds
wide use, principally as a moderate-strength Lewis acid and in
several other reactions.


In textile
processing
Concentrated aqueous solutions
of more than 64% weight/weight Zncl2 in water have the interesting property
of dissolving starch, silk,
and cellulose. Thus, such solutions cannot be
filtered through standard filter papers. Relevant to its affinity for these
materials, ZnCl2 is used as a fireproofing agent and in fabric "refresheners"
such as Febreze.
Dry Cell  or Batteries

It is commonly used in dry cell
batteries as an electrolyte where it also acts as a moisture absorbent and
corrosion inhibitor.
Electroplating

Today, there are three primary types of acid zinc
plating baths: straight ammonium chloride, straight potassium chloride and mixed
ammonium chloride/potassium chloride.
Petroleum
It is an excellent emulsion breaker
and is used to separate oil from water. It is also an effective packer fluid in
oil and gas wells due to its high specific gravity.
Chemical
It is used in the production
of ethylacetate. It is also used as condensing agent for
the production of organic dye-stuff. It  is used as a
stabilizing agent for diazonium compounds. It is used for
the production of active carbon. It is used for
Friedel Craft Reaction,
Azotropic or Azeotropic Distillation,

Desiccation. Zinc laurate, linoleate Stearate or resinate can be formed
from
ZnCl2 solutions and solutions of the corresponding sodium salt. Zinc
chloride is
a Lewis acid and therefore electrophilic in character. Zinc Chloride is
particularly
effective in catalyzing reactions that eliminate molecules of water,
ammonia or mercaptans. Its solutions gelatinize cellulosic materials and
induce cross
linking in such polymer formers as the methylol ureas. It absorbs
readily on
charcoal or silica for catalyzing acylations and alkylations by
Friedel-Crafts
synthesis. In esterifications and condensation reactions, it facilitates
the
elimination of water or ammonia molecules from the reactants. One
example is the
Fischer idole synthesis.
Herbicide
Zinc Chloride is used as an herbicide. It is used to control
lichen and moss growing on the roofs of houses and other domestic dwellings,
along walks, driveways, fences, and wherever moss grows.
Agriculture
It is very rarely used in
agriculture. ZnCl2 may be reacted with chelating agents to form solutions of
zinc that are biologically available to plants and animals.


Resins
It is used in Ion - Exchange resins production.

Paints
It is used in for the production of lithopone
and as pigment for zinc chromate.
Rubber
It is used as accelerator in the vulcanizing
process of rubber.


Glue, wood working
Zinc Chloride is used in for the preservation of glue, and
for the impregnation of timber.
Printing
It is used in off-set in the chemical products.

Odor Control
It reacts with sulfide to minimize release of H2S gas in waste
treatment facilities.
Oil-Gas Wells
High-density solutions of zinc chloride and calcium chloride give
good performance in well completion and work-over operations; the
solutions also used as packer fluids under certain well conditions. It
has been used in specialty corrosion inhibitors and invert emulsion
breakers.
Vulcanized Fiber & Reclaimed Rubber
Water-leaf paper is gelatinized with ZnCl2 solution is lesstacky,
drier and less moisture-absorbent than caustic reclaimed rubber. It not
only dissolves the cellulosic fibers in the scrap, but also catalyzes
depolymerization of the elastomer. Similar method is used for rubber
reclaimed from natural, styrene-butadiene rubber (SBR), and mixed scrap
Animal drug
It is used for the production of zinc
bacitracin.



..and several other uses.
