Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. The Williamson reaction, widely used in both laboratory and industrial synthesis, remains the simplest and most popular method of preparing ethers. Rinse skin with water/ shower. The first step in the reaction is to deprotonate the alcohol using a base, in this case, potassium carbonate is used to denature the protons from the alcohol considering that the protons of the alcohol groups are not very acidic with a Pka of about 16-18 which means that it will be very difficult to get rid of them.
