Industrial DCM Grade for Extraction and Recovery
Methylene Bichloride is supplied by Wenzhou Yu'ao Electric Co., Ltd. as an industrial-grade solvent for selected extraction, dissolution, and solvent recovery processes. The reference purity is ≥99.5%, subject to the confirmed supply specification. Its boiling point of approximately 39.8°C can support lower-temperature solvent recovery, although actual performance depends on the equipment, operating conditions, and process design.
Process Requirements and Impurity Limits
Purity and impurity requirements should match the intended application. The boiling point provides a reference for recovery planning, but it does not determine recovery efficiency on its own. Buyers can specify limits for water, acidity, and other relevant impurities according to their process requirements. These limits should be agreed upon before ordering to provide a consistent basis for batch acceptance. Packaging options include closed drums, tank cars, or other compliant formats, subject to order and transport conditions.
Requirements for Solvent Recycling
For processes that recover and reuse the solvent, buyers should define the permitted impurity levels so the available grade can be evaluated against the reuse requirements. The purchase specification can include water content, acidity, other relevant chlorinated impurities, packaging format, and delivery arrangements. Final acceptance follows the agreed order requirements and the applicable batch certificate of analysis (COA).
Inspection, Packaging, and Payment
Quality checks are carried out before dispatch, with 100% inspection before packaging according to the stated quality process. Third-party inspection can be arranged in advance. Net packaging weight, transport method, and available quantity are confirmed against actual supply conditions. EXW, FOB, and DDP terms are available, with full prepayment in RMB or USD. The standard minimum order quantity is 15 tons. Packaging, loading, and transport must comply with applicable dangerous goods requirements and the product safety data sheet (SDS).
FAQ
Q: Can industrial-grade Methylene Bichloride be used directly in an existing process?
A: Suitability depends on material compatibility and the process's quality requirements. Compare the supply specification with the existing process standard and conduct a small-batch validation where necessary.
Q: Can dichloromethane be shipped by tank car?
A: Tank-car or drum delivery can be discussed based on order quantity, supply conditions, and applicable dangerous goods transport requirements. Packaging and delivery arrangements must be confirmed before ordering.
Q: Can samples or third-party inspection be arranged before a bulk purchase?
A: Paid samples can be discussed; free samples are not provided. Third-party inspection can also be arranged in advance, with test items, acceptance criteria, and timing agreed upon before dispatch.
