18-Crown-6 is a kind of macrocyclic ether organic compound. It is mainly used as phase transfer catalyst for fine organic synthesis, complexing agent, extractant for separation and extraction of precious metals and rare earth elements. In chemical analysis, it can be used for ion enrichment, separation and masking. It can also be used in medicine, biochemistry and electronic industry as ionic conductive materials and liquid crystal display elements.

White crystal or powder, relative density 1.50. Deliquescence is strong; It is easily soluble in water and also soluble in organic solvents such as low concentration methanol, ethanol, acetone and carbonate. Decompose when exposed to air or heated. When exposed to the air or heated, lithium hexafluorophosphate decomposes rapidly in the air due to the action of water vapor, releasing PF5 and producing white smoke. Lithium hexafluorophosphate is mainly used as electrolyte material for lithium ion battery. Lithium hexafluorophosphate electrolyte is mainly used in the manufacture of lithium ion batteries.

Lithium carbonate (Li2CO3) is a colorless to white crystal, which is soluble in water, but has poor solubility. It is used for the treatment of mental illness, and is mostly used for the treatment of mania.

Raw materials for preparing metal lithium; Used as welding agent for aluminum, dehumidifier for air conditioning and raw material for special cement; It is used in flame and in the production of lithium manganese battery electrolyte in the battery industry

As photoinitiator, it is mainly used for silk screen printing ink, lithographic printing ink, flexo printing ink and wood coating. TPO can be completely cured on the pigmented surface of white or high titanium dioxide. It is widely used in various coatings. Because of its excellent absorption performance, it is especially suitable for silk screen printing ink, lithography, flexographic ink and wood coating. The coating does not turn yellow, the post polymerization effect is low and there is no residue. It can also be used for transparent coating, especially for products with low odor requirements. When used alone in unsaturated polyester containing styrene system, it has high initiation efficiency. Acrylate systems, especially colored systems, usually need to be combined with amine or acrylamide and other photoinitiators to achieve complete curing of the system, especially for low yellowing, white systems and thick films. When the photoinitiator TPO is used with mob240 or cbp393, the curing efficiency can be improved. It is the best extraction solvent for petroleum aromatics units and is also used as formylation reagent in fine chemical industry.
