For procurement professionals in the chemical industry, understanding product specifications is fundamental to making informed purchasing decisions. Dibasic Ester (DBE), known by its CAS number 95481-62-2, is a highly versatile solvent and chemical intermediate, prized for its eco-friendly properties and broad applications. As a prominent supplier of specialty chemicals from China, we provide DBE that meets stringent quality parameters. This guide aims to clarify the key specifications of DBE to assist you in your procurement process.

The primary composition of Dibasic Ester is a mixture of three dimethyl esters: dimethyl succinate, dimethyl glutarate, and dimethyl adipate. These components contribute to its desirable characteristics, including its high boiling point, excellent solvency, and biodegradability. When sourcing DBE, procurement professionals should pay close attention to the following specifications:

  • Appearance: High-quality DBE is typically a Colorless transparent liquid. Any deviation from this, such as cloudiness or discoloration, might indicate impurities or degradation.
  • Purity/Ester Content: The typical specification for ester content is 99.0% minimum. This high purity ensures optimal performance in demanding applications. For formulators looking to buy Dibasic Ester 95481-62-2, verifying this purity level is crucial.
  • Compositional Breakdown: Reputable suppliers often provide a breakdown of the main components:
    • Dimethyl Succinate: Typically 15-25%
    • Dimethyl Glutarate: Typically 55-65%
    • Dimethyl Adipate: Typically 10-25%
  • Moisture Content: Low moisture is essential for solvent stability and performance. Standard specifications usually require 0.1% maximum moisture.
  • Acid Value: A low acid value, typically 0.2 mg KOH/g maximum, indicates minimal free acidity, which is important for preventing corrosion and ensuring product stability.
  • Color: The color is usually measured on the APHA scale, with a specification of 15 maximum, signifying a near-colorless liquid.
  • Distillation Range: DBE has a wide boiling range, typically 196-230°C, reflecting its high-boiling nature and slow evaporation rate.

Understanding these specifications is vital when comparing offerings from different suppliers. As a leading Dibasic Ester manufacturer in China, we ensure our DBE consistently meets these parameters, providing you with a reliable product for your applications. We encourage buyers to request detailed Certificates of Analysis (COA) to verify these specifications.
