Abstract

The influence of forced concn. variations on the oxidn. of hydrocarbons over a Pt gauze catalyst was examd. The period was varied between 0 and 120 sec. The periodic method of operation avoided temp. problems occurring at high conversions under stationary conditions. In the oxidn. of butane, the mean catalyst temp. could be maintained at 252-332 Deg. In the oxidn. of cyclohexene, the influence on product distribution (CO-CO2) of the kind of process operation was shown. The selectivity of the intermediate CO was 7-55%, according to the time period. [on SciFinder (R)]

Periodic table

The periodic table, also known as the periodic table of the elements, arranges the chemical elements into rows ("periods") and columns ("groups"). It is an organizing icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which says that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks.

Butane

Butane (ˈbjuːteɪn) or n-butane is an alkane with the formula C4H10. Butane is a highly flammable, colorless, easily liquefied gas that quickly vaporizes at room temperature and pressure. The name butane comes from the root but- (from butyric acid, named after the Greek word for butter) and the suffix -ane. It was discovered in crude petroleum in 1864 by Edmund Ronalds, who was the first to describe its properties, and commercialized by Walter O. Snelling in early 1910s. Butane is one of a group of liquefied petroleum gases (LP gases).

Oxidation state

In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. Conceptually, the oxidation state may be positive, negative or zero. While fully ionic bonds are not found in nature, many bonds exhibit strong ionicity, making oxidation state a useful predictor of charge. The oxidation state of an atom does not represent the "real" charge on that atom, or any other actual atomic property.
