General description

Lithium hydroxide monohydrate, 99.995% trace metals basis is a white colored salts. We offer highly pure and controlled specifications to fulfill research needs such as enhancing battery technology and improving lubricants to ensuring air quality in closed environments, and contributing to advanced materials in glass, ceramics, and polymers.

Application

Lithium hydroxide monohydrate (LiOH⋅H2O) is a crucial precursor for the production of lithium-ion battery cathode material such as lithium cobalt oxide (LiCoO2) and lithium nickel manganese cobalt oxide (NMC). Lithium hydroxide monohydrate is used in CO2 scrubbers to absorb carbon dioxide from the air. This application is crucial in closed environments such as submarines, spacecraft, and underwater habitats. Lithium hydroxide monohydrate can be used as a catalyst. In a recent study, it has been found that Lithium hydroxide monohydrate works as a novel catalyst for Knoevenagel condensation of aryl aldehydes with malononitrle and ethylcyanoacetate. Also it is used as highly efficient catalyst for Gewald reaction, for an easy and highly efficient synthesis of arylidene malononitrile,arylidene ethylcyanoacetate and 2-aminthiophenes.

Features and Benefits

The following benefits are the main feature of the product:
  1. requirement of a small amount while using as a catalyst,
  2. short reaction times, and
  3. high product yields etc
  4. Low trace metals content ( < 55.0 ppm)
