Preparation and physical properties of several aliphatic hydrocarbons and intermediates

Abstract

In t he co urse of a contin uin g investigation of the knock rat in gs of alip hatic hydrocarbons, pu re paraffin s and olefins have been prepared in quantities suffi cien t for en gin e teBts. Thi s reports describes the m eth ods of preparation a nd purification of t hree pcntancs. four hcxane , t hree heptanes, ro ur octanes, e igh t nonanes, seven decancs, fou r hexe nes, fi ve octenes, s ix nonenes, s ix dccencs, and a number of alcohoL, ketones, esters, and alky l hal ides . Most of t hese compounds were hi ghly pu r ified . Phys ical co nstants m casured include f rcez in g point, bo iling po in t, and its va ri ation w ith press ure, rcfractive index, a nd d ensity, and t hcir variations with temperat ure.
