Report on Atmospheric Distillation of the＂A＂Series of Fuel Oils and the Analysis of the Fractions

摘要

In this report are given the temperature at which the “A” aeries first begin to distill and the temperatures at which each 5％ fraction comes over up to 40％ , employing the Engler apparatus ordinarily used for the distillation of light petroleum products at atmospheric pressure.n(1)tIn this report will be found the carbon and hydrogen content of the first and the second twenty per cent distilled over as described by the specification for the Engler distillation. The residue remaining in the flask after this distillation was also analyzed for its hydrogen and carbon composition.n(2)tIn this report will be found the average molecular weight as found by the cryoscopic method using naphthalene as a solvent on the fractions described above.n(3)tThe findings in this report, while interesting and valuable for research, do not give any information that can be used by the Navy at this time as an aid in writing specifications.
