Packing
It can be packed in galvanized iron drums, net weight 250 kg/drum, or can be packed in ISO tank or IBC. It should be stored in cool and windy special warehouse far from fire and transported as a non-hazardous chemical product.
Scope of application
It is the main raw material of the synthesis of dimethyl carbonate in the chemical industry. It can be used for the removal of carbon dioxide and hydrogen sulfide which are in natural gas, oil cracking gas, oil gas, and synthetic ammonia transformation gas. It can be used as the curing accelerator for phenolic resin, dispersing agent, and plasticizer for water-soluble adhesives, oily solvents, the extracting agent for olefin and aromatics.
In the textile industry, it can be used as the auxiliary and fixing agent for synthetic, spinning solvents or the aqueous solvent dye pigment dispersing agent It can also be in place of the phenolic resin as wood adhesives
It can be used as a cleaner for optical lenses and electronic machinery, can be used as the solvent in soluble cutting oil, and as a solvent in the coating.
High-purity propylene carbonate can be used to produce lithium-ion battery electrolyte solvent and capacitor electrolyte.
