Ethylene Dichloride (EDC / 1,2-Dichloroethane)

Store only in approved closed systems in a cool, ventilated and secured hazardous area with ignition-source control. Prevent release to drains, soil and groundwater. Materials of construction, seals, pumps and gaskets must be selected for EDC service. Any packaging or bulk storage arrangement should be governed by the current SDS, applicable dangerous-goods code and the buyer’s site standard.
HSE control principle
Use the current product-specific SDS, local dangerous-goods requirements, receiving-site risk assessment and applicable engineering standards. Website text should never substitute for a supplier SDS or site procedure.

A technically meaningful RFQ should define the key quality parameters that control EDC performance in the intended process. The following tests are representative, and the final test methods should always match the producer specification or customer process requirements. Typical COA requirements include purity, water content, high-boiling residues, low-boiling impurities, acidity/HCl, colour and appearance, and density. Purity is commonly measured by GC to confirm main feedstock quality, while water content is determined using Karl Fischer analysis due to its impact on cracking/purification performance and corrosion behaviour. High-boiling residues are evaluated by GC or residue methods to control heavy ends and potential furnace fouling, while low-boiling impurities are measured by GC for separation efficiency and process control. Acidity/HCl content is monitored using supplier-specific methods as an indicator of corrosion and degradation risks. Additional quality checks include colour and appearance (visual inspection or APHA where specified) for contamination or ageing indication, and density measurement according to ASTM D4052 or equivalent methods for product identity and receiving verification. Final COA requirements should be aligned with the producer specification, customer requirements, and intended application.
