Excerpt from Report of G. T. Clarkson, Esq. On the Prices of Gasoline and Oils, 1926: Sold to the People of OntarioAccording to testimony given the motive or impulse values of gasolines are largely provided by the heavier naphthas contained in them, but to give a maximum of service a gasoline requires to be of such composition and balance as will with its use give a quick initial starting point, high value in power, a level impulse throughout the whole period of use and ultimately freedom from carbon and precipitation with such use. Distillation tests are ordinarily employed to determine the character and quality of gasolines, in that such tests indicate the starting point, regularity or irregularity of impulse throughout the whole period of consumption, and the degree to which unsaturated hydro carbons are contained. Other tests, such as the Doctor test to detect the amount of sulphur compounds, colour test, odour test and acidity test are also employed to greater or lesser extents to determine freedom from impurities.Premium priced gasolines command, when sold at retail, from two to three cents more per imperial gallon than do other commercial gasolines, and under distillation tests the first drop over of such gasolines ordinarily occurs at between 100 and 110 degrees Fahrenheit, 40 to 55 per cent. Becomes distilled at a tem perature of 221 degrees and complete distillation - or the end point-occurs at about 375 degrees, while a recovery of from 97 to 98 per cent. Is Obtained. Gasolines which are not premium priced include both refinery straight run gasolines - ordinarily between 58-60 gravity - and also blended gasolines which range up to 64-66 in gravity. If imported from the United States of America, to conform to the United States Government Motor Gasoline standard, thefirst drop over in distillation of such 58-60 gasolines must occur at not more than 131 degrees Fahrenheit, 20 per cent. Over at 221 degrees, 50 per cent. Over at 284 degrees, with an end point of not more than 437 degrees Fahrenheit and a recovery of not less than 95 per cent. Schedule B attached hereto is a state ment of analyses made of 22 samples of gasolines collected in Ontario during July and August, 1925, and it shows that, with isolated exceptions (being imported products) such gasolines then sold in Ontario were well within such specifications and of better grade than required under them in that the starting and end points are below those specified.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
