Why Are Boiling Chips Used In Esterification at Alyssa Hobler blog

Why Are Boiling Chips Used In Esterification. Boiling chips are small, insoluble, porous stones made of calcium carbonate or silicon carbide. It works well because the ester has the lowest boiling point of anything present. Boiling stones (or boiling chips) are small pieces of black porous rock (often silicon carbide) that are added to a solvent or solution. The ester is the only thing in the mixture which doesn't form. Boiling chips (pieces of porous pot) provide an additional source of minute air bubbles which act as a nucleus for building bubbles of vapour in the liquid, allowing the liquid to boil quietly. For esters in which the alcohol and carboxylic acid are sterically unhindered, a 1:1 mixture of alcohol and carboxylic acid will yield an equilibrium mixture that is about 70% ester. The overall process of esterification is one involving an equilibrium among a variety of compounds, and for the reaction to give a high. Generally, the injected microbubbles are anhydrous, so water vapour is typically present below saturated humidity. These stones have pores inside which provide cavities both to trap air and to provide spaces.
