What is chlorine
Chlorine (Cl), also identified by Chemical Abstracts Service (CAS) number 7782-50-5, is a light, highly reactive gaseous element exhibiting a yellow-green color at room temperature. Although pure chlorine is too reactive to exist in its original state, various naturally occurring chlorine compounds are essential to human life. For example, the hydrochloric acid in our stomachs aids digestion by breaking down food and killing harmful bacteria. And most of us have used sodium chloride (table salt) to season our food. Chlorine gas is produced via the electrolysis of a sodium chloride solution, which yields a caustic soda known as sodium hydroxide along with hydrogen gas. Brenntag North America is a top chlorine gas distributor for industrial and manufacturing applications.
Chlorine uses and applications
Chlorine gas has numerous uses in our everyday lives. Its ability to destroy bacteria makes it valuable for disinfecting drinking water and keeping the water in swimming pools clean. It is also widely used in the manufacturing of chemicals and pharmaceuticals. It’s estimated that as many as 85% of medicines, including several lifesaving drugs, are produced via chlorine chemistry. Approximately 25% of medical devices such as blood bags, heart catheters, and X-ray films also contain chlorine. And two-thirds of all chlorine is used in the manufacturing of plastic materials such as PVC, polyurethanes, Teflon, and epoxy resins for the automobile industry. Manufacturers must exercise caution when using chlorine gas in their processes, as even a small spill or leak can have deadly consequences.
Industries Where Chlorine Is Commonly Used
A range of sectors use chlorine, including the following:
These varied industries take advantage of the different strengths and chemical makeup of chlorine. The extensive use of chlorine by multiple industries, however, requires organizations to have a reliable chlorine supplier. See how these industries use chlorine:
A chemical plant uses chlorine as a reagent for chemical, plastic, and agrochemical applications.
A medical manufacturer uses chlorine to produce hospital equipment, including IV bags.
A pharmaceutical company uses chlorine to create medicine for treating cancer, pain, allergies, and more.
A textile manufacturer uses chlorine to bleach products like clothes.
A water treatment facility uses chlorine to disinfect drinking water, which removes bacteria and microbes.
CHLORINE PROPERTIES AND CHARACTERISTICS
Chlorine exists in four oxides: chlorine monoxide, chlorine dioxide, dichlorine heptoxide and dichlorine hexoxide, each of which is highly reactive and unstable. Chlorine can also displace heavier halogens like bromine and iodine.
It's chemical formula is CI- and its melting point is -101° C (-149.8° F), while its density is 3.21*10 -3 g.cm -3 at 20° C. The atomic mass of chlorine is 35.453 g.mol -1. Chlorine’s boiling point is -34.6° C, while it electronegativity according to Pauling is 3.0.
In appearance, chlorine shows as a greenish-yellow gas or amber liquid. It will almost always have a strong, pungent odor that some find nauseating.
As chlorine is a highly toxic product, it requires extreme care when transported, stored, and handled.
For maximum safety, facilities should store chlorine in a cool, dry, and well-ventilated area away from any ignition sources, heat, or incompatible materials. Room temperatures should not reach or exceed 52 C or 125 F. Most recommendations suggest storing chlorine in an isolated and detached building. Facilities should secure chlorine containers using a chain or other device that keeps the container in an upright position.
Safety Guidelines when handling Chlorine
When handling chlorine, staff members need to follow strict safety guidelines, including wearing:
- Chemical protective clothing
- Chemical safety goggles
- Chemical protective suits
Facilities should also maintain functioning eyewash stations and emergency showers in case a staff member comes into contact with chlorine.
Key commercial identifiers for chlorine include:
- CAS Number: 7782-50-5
- European Community (EC) Number: 231-959-5
- Unique Ingredient Identifier (UNII): 4R7X1O2820
Companies looking for a chlorine supplier should choose one with an extensive background handling, storing, and transporting chlorine. You want a partner that prioritizes safety and understands chlorine's chemical properties. When you work with a business with that kind of knowledge and expertise, like Brenntag North America, you can count on a seamless experience.
