Drying oil the allylic radical intermediates are less stable (i.e., slower to form). The early stages of the drying process can be monitored by weight changes in an oil film. The film becomes heavier as it absorbs oxygen. Linseed oil, for instance, increases in weight by 17 percent. As oxygen uptake ceases, the weight of the film declines as volatile compounds evaporate. As the oil ages, further transitions occur. A large number of the original ester bonds in the oil molecules undergo hydrolysis, releasing individual fatty acids. In the case of paints, some portion of these free fatty acids (FFAs) react with
H. G. Hotchkiss Essential Oil Company Plant H. G. Hotchkiss Essential Oil Company Plant H. G. Hotchkiss Essential Oil Company Plant is a historic factory located at Lyons in Wayne County, New York. The remaining two story commercial building is an example of a small frame structure featuring a double storefront with modest ornamentation. It was built about 1884 on the foundations of an earlier structure and is located on the bank of the original Erie Canal. It was occupied by a major producer of essential oils, principally peppermint oil used in the manufacture of patent medicine. It was listed on the National Register of Historic Places
