The kinetics of the slow combustion of the three xylene isomers have been studied manometrically in a quartz vessel, under static conditions at subatmospheric pressures over the temperature range from 410 to 550 degrees, employing 1:1 to 1:20 hydrocarbon: oxygen mixtures. It was shown that W-...
Stearic acid (C18H36O2) is a fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fac ...
The second stage cracks and breaks down larger hydrocarbon molecules into smaller ones used to produce gasoline. This process ensures the gasoline has desirable properties, like low sulfur content and a high octane rating. Refineries use two methods. One is catalytic cracking, which uses a catalyst...

The term “alkyl” is intended to include both C1-30branched and straight-chain, unsaturated aliphatic hydrocarbon groups having the specified number of carbon atoms. Examples of alkyl include but are not limited to, methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, t-butyl, n-pentyl,...
Alkenyl functional organopolysiloxanes suitable for use in the method of the present invention are those including structural units of the formula (I): R1aSiO4−a/2(I) wherein: each R1is independently hydroxyl or a monovalent hydrocarbon radical, and ...
Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025 g of naphthalene burns in a bomb calorimeter, the temperature rises from 24.25 °C to 32.33 °C. Find ΔErxn for the combustion of naphthalene. The heat capacity of the bomb ...
