- Usage
- Phase - Transfer Catalyst: It is an effective phase - transfer catalyst, which can transfer reactants from the aqueous phase or organic phase to the other phase, accelerating the reaction rate. It is widely used in organic synthesis reactions such as alkylation reactions, redox reactions, and ester hydrolysis.
- Drug Synthesis: It is used in the synthesis of drug intermediates such as benzyltriethylammonium chloride and ethyl cinnamate, and is also involved in the synthesis of organic drugs such as bacampicillin and sultamicillin.
- Other Fields: It can also be used as a reagent for high - performance liquid chromatography, a surfactant, a scale remover, etc. It can be used as a curing accelerator in the polymerization process of powder coatings, epoxy resins, etc., and as a phase - change energy - storage material in the refrigeration system.
- Packaging and Storage
- Packaging: Usually 25 kg/drum, packed in cardboard drums. It can also be packed in double - layer plastic bags sealed, with a moisture - proof paper drum or plastic drum outside.
- Storage: Should be stored in a dry and ventilated warehouse, and kept sealed and dry to avoid moisture.
- Toxicity
It is toxic by inhalation, ingestion and skin contact, and is irritating to skin, eyes and respiratory system. The oral LD50 of rats is >1000 mg/kg, and the oral LD50 of mice is 1000 - 2000 mg/kg.
