Benzyltriethylammonium Chloride (TEBAC), identified by CAS number 56-37-1, is a fascinating chemical compound that finds extensive application as a phase transfer catalyst, particularly in organic synthesis. Understanding its chemical structure, properties, and synthesis pathways is crucial for chemists and procurement specialists looking to leverage its capabilities. As a key intermediate, sourcing high-purity TEBAC from reliable manufacturers, especially those based in China, offers significant advantages in terms of quality, cost, and supply chain stability.

Unpacking the Chemistry of TEBAC

TEBAC is a quaternary ammonium salt, meaning it features a nitrogen atom covalently bonded to four alkyl or aryl groups, carrying a positive charge. In TEBAC, this nitrogen is bonded to a benzyl group and three ethyl groups, with a chloride ion serving as the counterion. Its molecular formula is C₁₃H₂₂ClN, and it has a molecular weight of approximately 227.78 g/mol.

Key chemical properties include:

  • Phase Transfer Capability: The lipophilic nature of the benzyl and ethyl groups allows the TEBAC cation to dissolve in organic solvents, while its positive charge enables it to form ion pairs with anions from aqueous solutions. This dual solubility is the basis of its effectiveness as a phase transfer catalyst, facilitating reactions between immiscible phases.
  • Stability: TEBAC generally exhibits good thermal stability and is stable under typical reaction conditions. However, like many quaternary ammonium salts, it can decompose at high temperatures.
  • Solubility: It is soluble in water and polar organic solvents like alcohols, and less soluble in non-polar solvents.
  • Purity: For its catalytic and intermediate roles, high purity levels, often exceeding 99%, are preferred. This ensures consistent performance and minimizes interference from impurities in chemical reactions.

Synthesis and Manufacturing Excellence

The synthesis of Benzyltriethylammonium Chloride typically involves the reaction of benzyl chloride with triethylamine. The process generally occurs via a Menschutkin reaction, where the tertiary amine (triethylamine) undergoes nucleophilic attack on the alkyl halide (benzyl chloride), forming the quaternary ammonium salt. The reaction is often carried out in a suitable solvent, and the product is then isolated through filtration and drying.

The efficiency and purity of the synthesized TEBAC depend heavily on the precise control of reaction parameters, including temperature, reactant ratios, and solvent selection. As a leading manufacturer, we have optimized these processes to ensure the production of high-quality TEBAC that meets stringent industry standards.

Why Source from China?

For companies seeking to buy Benzyltriethylammonium Chloride CAS 56-37-1, sourcing from China offers a compelling proposition:

  • Competitive Pricing: Chinese manufacturers often provide TEBAC at more competitive price points due to large-scale production capabilities and optimized supply chains, leading to significant cost savings for buyers.
  • Reliable Supply Chain: China's robust chemical manufacturing sector ensures a consistent and stable supply of TEBAC, which is crucial for uninterrupted operations and production planning.
  • Quality Assurance: Reputable Chinese chemical suppliers are committed to quality control and often adhere to international standards, ensuring that the TEBAC purchased meets high purity requirements.
