Description

Boron Trifluoride - Butanol Reagent (10-20%) [For Esterification] (1Ml*10) is a specialized chemical solution where boron trifluoride gas is complexed in butanol, creating a powerful and convenient Lewis acid catalyst. This reagent is essential for driving efficient esterification and transesterification reactions, offering superior reactivity and selectivity compared to traditional protic acids. It is a critical tool for synthetic organic chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries, where precise and high-yielding synthesis is paramount.

Application

• Esterification Catalyst: Primary application for the synthesis of esters from carboxylic acids and alcohols, a fundamental reaction in organic synthesis.
• Transesterification Reactions: Catalyzes the exchange of alkoxy groups in esters, crucial for biodiesel production and polymer synthesis.
• Friedel-Crafts Acylation & Alkylation: Serves as a potent Lewis acid catalyst for introducing acyl or alkyl groups onto aromatic rings.
• Polymerization Initiator: Used in the production of certain specialty polymers and resins.
• Fine Chemical & Pharmaceutical Intermediates: Enables the synthesis of complex molecules, including active pharmaceutical ingredients (APIs) and fragrances.
• Laboratory Research & Development: A staple reagent in R&D labs for method development and small-scale synthesis.
