Excerpt from Contributions to Geochemistry, 1949 A method is presented for the distillation and photometric estimation Of the Oil yield Of Oil-bearing shales. The Oil Shale is distilled in a closed test tube and the Oil extracted with toluene. The Optical density Of the toluene extract is used in the estimation Of Oil content and is converted to percentage Of Oil by reference to a standard curve. This curve is Obtained by relating the Oil yields determined by the Fischer assay method to the optical density Of the toluene extract Of the Oil evolved by the new procedure. The new method gives in a much Shorter time results similar to those obtained by the Fischer assay method. The applicability Of the new method to Oil-bearing shale and phosphatic shale has been tested. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
