The Chemistry of Essential Oils and Artificial Perfumes, Volume 2 by Ernest J. Parry is a comprehensive exploration of the chemical constituents found in essential oils and the synthetic compounds used in perfumery. Building upon the foundational knowledge presented in Volume 1, this volume delves into the intricate analyses of essential oils, examining their isolated components and the methodologies employed in their extraction and identification. Parry offers detailed monographs on various essential oils, providing insights into their chemical compositions and the techniques used to isolate and study their individual constituents.​

A significant portion of the book is dedicated to the study of synthetic aromatic compounds that play a crucial role in modern perfumery. Parry discusses the synthesis of these compounds, highlighting their chemical structures and the processes involved in their creation. The volume also covers the analytical methods used to assess the quality and authenticity of both natural and synthetic oils, emphasizing the importance of precision and accuracy in the field of fragrance chemistry.​

In addition to the technical aspects, Parry provides a historical context for the development of perfumery, tracing the evolution of fragrance materials from natural sources to the incorporation of synthetic alternatives. This perspective underscores the dynamic nature of the industry and the continuous advancements in chemical research that have shaped contemporary perfumery practices.​

Volume 2 serves as a valuable resource for chemists, perfumers, and enthusiasts interested in the scientific underpinnings of fragrance materials. Parry’s meticulous research and clear presentation make this work an essential reference for understanding the complex chemistry of essential oils and artificial perfumes.
