In 1946 the Scientific Committee began the compilation of a set of monographs embodying the EOA standards for essential oils, aromatic chemicals and isolates, and related flavor and perfume materials. Approximately 300 of these have now been completed. They have been prepared by the scientific representative of the member companies, based on the analyticaI data and experience of their laboratories. They are intended to define realistically standard good quality material currently avaiIable commercially, and should provide fair standards for the evaluation of these materials in commercial transactions.
A short symposium was held by the Essential Oil Association on the problems affecting manufacturers and their supplies of both natural and synthetic raw materials. Four reports were given on various aspects of this subject and are summarized below:
Methods leading to (–)-, (+)-, and (±)-carvone have been reviewed, The technical production of (–)-carvone is based on the widely available (+)-limonene; the most favored route is that epitomized in Chart 1. Though the steps involved are simple, their exploitation is a wellguarded secret, There is no similar commercialscale production of (+)-carvone because the basic materials for its synthesis are not as readily available. However, sooner or later the rising demand for this ketone will ensure that it, too, will be produced synthetically.
