Arsenic Trioxide[ORDER]
Another name: arsenous anhydride; White arsenic
(Molecular) formula: As2O3
(Molecular) weight: 197.84
UN NO.: 1561
Hazard class NO.: 6.1
Pack Group: ¢ò
Physical and chemical nature:
Odourless. White powder or crystal. Three crystal shapes:
monoclinic crystal,cubic crystal and amorphous crystal. Among
them, monoclinic crystal sublimates at 193¡æ,with a relative
density of 4.15;of cubic crystal the relative density is 3.865;while
amorphous crystal 3.738,has a melting point of 312.3¡æ.Arsenic
trioxide dissolves a little in water and generates in to the
relative acid. Monoclinic and cubic crystals dissolve in ethanol,
acids and alkalis; amorphous crystal dissolves in acids and
alkalis, but insolubilizes in ethanol,acids and alkalis;amorphous
crystal dissolves in acids and alkalis,but insolubilizes in
ethanol.The foreign matters contained in their industrial
products are different, appearing subtle red, grey or yellow.
Usage:
Used to refine the element arsenic. It is the material for
the smelting of arsenic alloy and the manufacture of semiconductor.
In the glass industry it is used as a clarificant and a decolorant
to improve the translucency of glass products. In the leather
industry it is used to make sodium nitrite, a leather preservative.
In agriculture it is used as a disinfectant and a rust inhibitor
for insect prevention, and also the material of other arsenic-containing
pesticides. Otherwise, it is applied in the manufacture of
dyes and paints, gas desulfurization, wood corrosion prevention,
boiler scale prevention and the production of ceramic and
enamel. Also used as a chemical reagent.

Package, storage and transportation:
Packed in a wood box lining with two layered firm paper
containers or polyethylene plastic bags, binded with iron wires
or sheets. The net weight per box is 50kg.On the package it
should be clearly marked "deadly poisonous product".
It is an inorganic deadly poison, with a dangerous standard
serial number:81008. It should be stored in an aeration-drying
storehouse. The vessels must be sealed up and kept separate
from edible materials, preserving it from damp air and leaking.
It must be carefully supervised. After every use, all those
present must change their clothes immediately, wash their hands
thoroughly and avoid eating.
In case of fire, it can be put out by water and sandy loam. |

Zinc chloride[ORDER]
(Molecular) Formula: ZnCl2
(Molecular) Weight: 136.30
Physical and chemical nature:
White, hexagonal system, granular crystal or powder. The relative
density is 2.91(25/4¡æ).The melting point is 283¡æ.The boiling
point is 732¡æ.It dissolves easily in water, also in methanol,
ethanol, glycerine, acetone and ether, but insolubilizes in
liquid ammonia. With a strong hygroscopy, it will be deliquesced
by absorbing water under the bare air. Otherwise, it can dissolve
metal oxides and cellulose. Fused zinc chloride has a very good
electric conduction. When scorched, it will generate a thick
white smoke. It is corrosive and poisonous.
Usage:
In the organic synthetic industry it is used as the dehydrated
agent, the condensate agent, and the catalyzer for the production
of Vanillin, anti-inflammatory painkiller and cation exchange
resin. Also used as the solvent of polypropylene. In the dyeing
and weaving industry it is the material (solutizer for cotton
fiber ) for the production of the sliver buckets and shuttle,
improving the binding property of fiber. In the dye industry,
as the stabilizing agent for azoic developed dyes it is applied
in the production of the activated and cation dyes. Besides
these, it is also the cleansing agent for petroleum. the activating
agent for activated carbon, the fire retardant for hard cardboards
and cloth products, and the welding agent for welding electrodes
in eletroplates. In the metallurgy industry, it is applied in
the production of aluminum alloy, light metal deacidification,
and the proofing for metal surface oxide layer. It is also applied
in the production of blueprints. Otherwise, it is used as battery
electrolyte and the material for the production of zinc cyanide
and non-fusible fire-extinguishing foam.

be marked clearly "Corrosive products". Store in an
aeration -drying storehouse. Don't place in the open air. The
vessels must be sealed up, preserving it from damp air. It should
not be stored or transported with foods and feeds. During transportation
it should be covered and kept away from the sunshine and rain.
During loading and unloading it should be moved with great care,
avoiding breakage, the storage duration of model ¢ñand model
¢ò products which are packed in the zinc-plate metal pail, the
cardboard pail or the plastic pail is six months, while in the
compound plastic braided bag, two months. The storage duration
of model ¢ó product is two months. All times are calculated from
