Boron trifluoride-methanol solution
Boron trifluoride-methanol solution (CAS 373-57-9), with the linear formula BF₃·MeOH and a molecular weight of 99.85 g/mol, is a chemical reagent supplied by TSS. This 14% solution in methanol is primarily utilised as a Lewis acid catalyst in organic synthesis, particularly in esterification and polymerisation reactions. Its reactive nature necessitates careful handling and storage.
Esterification Catalyst
Boron trifluoride-methanol solution serves as an effective catalyst for the esterification of carboxylic acids with alcohols. It facilitates rapid formation of esters under mild conditions.
Polymerisation Initiator
This reagent can act as an initiator or catalyst in certain polymerisation processes. Its Lewis acidic properties enable the activation of monomers for chain growth.
Organic Synthesis Reagent
Utilised broadly in organic synthesis, it participates in various reactions requiring a strong Lewis acid, such as Friedel-Crafts alkylations and acylations, and as a source of the BF₃ moiety.
