Lithium Hydroxide Monohydrate and Anhydrous Pure and USP Grade Manufacturers
CAS Number: 1310-66-3 monohydrate or 1310-65-2 anhydrous
Please visit SDS, Safety Data Sheet of Lithium Hydroxide Pure and USP Grade Manufacturers.
Lithium hydroxide monohydrate or anhydrous is a white hygroscopic crystalline material. It is available commercially in anhydrous form and as the monohydrate which is more common. It is used in alkaline storage batteries and in preparation of other lithium salts. Used as a catalyst in the production of alkyd resins in esterifications. Also, used in the production of lithium soaps, sulfonates and greases.

DEFINITION
Lithium Hydroxide contains NLT 98.0% and NMT 102.0% of lithium hydroxide (LiOH), calculated on the anhydrous basis.
A. When moistened with hydrochloric acid, it imparts an intense crimson color to a nonluminous flame.
Chloride and Sulfate, Sulfate:
Sample: 2.0 g
Acceptance criteria: It shows no more sulfate than corresponds to 1.0 mL of 0.020 N sulfuric acid (0.05%).
Calcium:
Sample solution: Dissolve 3.33 g in 50 mL of 3 N hydrochloric acid. Boil the clear solution to expel carbon dioxide, add 5 mL of ammonium oxalate, render alkaline with 6 N ammonium hydroxide, and allow to stand for 4 h. Pass through a filtering crucible, and wash with warm water until the last washing yields no turbidity with calcium chloride. Place the crucible in a beaker, cover it with water, add 3 mL of sulfuric acid, and heat to 70C.
Analysis: Titrate the Sample solution with 0.10 N potassium permanganate to a pale pink color that persists for 30 s.
Acceptance criteria: NMT 3.34 mL of 0.10 N potassium permanganate is consumed (0.20%).
Carbonate:
[Note: While pipeting and during the subsequent titrations, keep the contents of the flasks blanketed with a stream of carbon dioxide-free air.]
Analysis: To the flask containing the completed Final titration obtained in the Assay, add 1 drop of methyl orange TS. Titrate with 0.1 N hydrochloric acid VS until a persistent orange color is produced and no undissolved barium carbonate remains. Perform a blank titration to determine the volume of 0.1 N hydrochloric acid consumed in going from the phenolphthalein endpoint to the methyl orange endpoint. To 100 mL of carbon dioxide-free water in a 250-mL conical flask, add 3 drops of the Sample solution from the Assay, 20 mL of 1 N barium chloride, and 3 drops of phenolphthalein TS. Allow to stand for 2 min. Titrate this solution with 0.1 N hydrochloric acid. At the discharge of the pink color of the indicator, add 1 drop of methyl orange TS, and titrate with 0.1 N hydrochloric acid VS until a persistent orange color is produced.
Acceptance criteria: The titration shows no more carbon dioxide than corresponds to 1.5 mL of 0.10 N hydrochloric acid (0.7%).
Lithium Content: To pass the test by Flame photometry.
Acceptance criteria: 28.1%–29.9% on the anhydrous basis.
Water Determination:
Analysis: Dry at 135C at a pressure of NMT 5 mm of mercury for 1 h.
Acceptance criteria: 41.0%–43.5%
Packaging and Storage: Preserve in tight containers.

Barter
They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.
They assign the credit of their hard work to your blessings
They keep you amused.
They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.
They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.
They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.
They offer you a small bribe as advance for booty, called lottery
They love to dream.
I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you.
