Omissions? The entrepreneurial spirit of independent record labels anticipated the radical economic…, Ether, any of a class of organic compounds characterized by an oxygen atom bonded to two alkyl or aryl groups. [4], Williamson is credited for his research on the formation of unsymmetrical ethers by the interaction of an alkoxide with a haloalkane, known as the Williamson ether synthesis. [2][3], In 1849, with the support of Thomas Graham, Williamson was appointed professor of analytical and practical chemistry at University College, London. In 1850 he discovered the structural relation between ethers and alcohols: in ethers the oxygen atom links two hydrocarbon groups, whereas in alcohols the oxygen is bonded to a hydrocarbon group and a hydrogen atom. In 1854 Williamson described the process of making ether from alcohol and revealed why an acid is needed as a catalyst. He is best known today for the Williamson ether synthesis. Error rating book.
