Description
Lithium hypochlorite, with the chemical formula LiOCl, is a white granular solid or tablet derived from concentrated solutions of sodium hypochlorite and lithium chloride. It consists of approximately 30% lithium hypochlorite and various other salts. LITHIUM HYPOCHLORITE is characterized by its chlorine odor, noncombustible nature, and its ability to accelerate the burning of combustible materials. It is generally toxic and acts as an irritant.
Uses
Used in Industrial & Institutional (I&I) Laundry:
Lithium hypochlorite is utilized as a laundry bleach in I&I laundry detergents and dry laundry bleaches. It does not precipitate soaps and other anionic detergents, making it suitable for use in the laundry industry.
Used in Swimming Pool Disinfection:
As a shocking agent, lithium hypochlorite is primarily used for disinfecting swimming pools. It effectively controls algae, bacteria, and mildew in swimming pool water systems, hot tubs, and spas.
Used as an Algicide, Disinfectant, and Fungicide:
Lithium hypochlorite serves as an algicide, disinfectant, and fungicide, particularly for controlling algae, bacteria, and mildew in swimming pool water systems.
Used in Food and Cheese Processing Plant Sanitization:
Lithium hypochlorite is employed as a sanitizer for food and cheese processing plant equipment, dairies, and eating establishment equipment and utensils, ensuring cleanliness and safety in the food industry.
Used in Cooling Water Treatment:
Lithium hypochlorite is also used as an oxidizing agent and sanitizer in cooling water treatment systems.
Chemical Properties and Preparation:
Lithium hypochlorite is a white, granular solid or tablet with a chlorine odor. It can ignite organic materials and is prepared by the action of chlorine on a solution of lithium hydroxide (LiOH). Its granular form with a 35% available chlorine content makes it suitable for super chlorinating swimming pools, especially those with hard water and high calcium levels. However, its low active strength and high cost make it more suitable for home pool disinfection rather than commercial pool disinfection.
Preparation
Lithium hypochlorite is prepared commercially from a purified solution obtained from the sulfuric acid-spodumene recovery process for lithium. The solution containing lithium, sodium, potassium, hydroxide and sulfate ions is chlorinated and evaporated. The solid is dried to yield an impure lithium hypochlorite having 35-40% available chlorine. The material is used as a bleach and disinfectant, particularly in home swimming pools.
Air & Water Reactions
Soluble in water. Decomposes slowly in water with the evolution of chlorine gas.
Reactivity Profile
LITHIUM HYPOCHLORITE is a powerful oxidizing agent. particularly in the presence of water or at higher temperature as LITHIUM HYPOCHLORITE decomposes to release oxygen and chlorine gases. Forms highly explosive NCl3 on contact with urea or ammonia. When heated or on contact with acids, produces highly toxic fumes of chlorine gas [Sax, 9th ed., 1996, p. 1905].
Health Hazard
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Safety Profile
A powerful oxidizer.
An eye, skin, and mucous membrane
irritant. When heated to decomposition it
emits very toxic fumes of Li2O and Cl-.
Used for swimming pool chlorination, and
as a laundry bleach. See also LITHIUM
COMPOUNDS and HYPOCHLORITES.
Check Digit Verification of cas no
The CAS Registry Mumber 13840-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13840-33:
(7*1)+(6*3)+(5*8)+(4*4)+(3*0)+(2*3)+(1*3)=90
90 % 10 = 0
So 13840-33-0 is a valid CAS Registry Number.
