Hydrogen hydrocarbons and

On August 10th-, 1801, W. Cruickshank1 noticed the gradual combination of oxygenated muriatic acid (i.e. chlorine) with hydrogen, hydrocarbons, and carbon monoxide. He said —... 

Why are there so many organic compounds The answer is that a relatively small number of atoms can bond together in a great many ways. Take molecules that contain only carbon and hydrogen (hydrocarbons) and have only single bonds. Such compounds belong to the family of organic molecules called saturated hydrocarbons, or alkanes. 

The feedstocks (straight-mn naphtha (SRN) and a blend of SRN and hydrocracked naphtha) and hydrotreated products were analysed by ASTM methods for density, carbon, hydrogen, hydrocarbon and boiling point distribution. Total sulfur was determined by ASTM D-4045 method, mercaptan sulfur by the potentiometric method (ASTM D-3227 and UOP-212), disulfides by the UOP-202 method, polysulfides by polarography [1], and elemental sulfur by the UOP-286 method. The Perkin-Elmer gas chromatograph (Model 8700), equipped with a flame photometric detector (GC/FPD) and a DB-1 fused silica capillary column (30 m x 0.53 mm), was used for identification of individual sulfur compounds [2-6]. The sensitivity of the GC/FPD technique was maximized by optimizing the gas flow rates and temperature programming as presented elsewhere [1].

It is also possible to mix nitrogen with controlled amounts of hydrogen, hydrocarbons, and/or ammonia to produce atmospheres capable of most, if not all, controlled-atmosphere treatments. The only exceptions arise when metals containing strong nitride formers are to be treated, in which case a similar atmosphere based on argon is preferred. The actual choice will depend on the duration of the treatment compared with the rate of reaction with nitrogen gas. In fact, the rate of uptake of nitrogen from N2 gas is much lower than when ammonia is present as the uncracked molecular species.

Development of fuel cells accelerated with the energy crisis of the 1970s. The fuels used most frequently are hydrogen, hydrocarbons, and alcohols. Normally, hydrogen is not a primary fuel but is produced from the others and used primarily in low-temperature cells. Table 17.2 describes the characteristics of the most important types, and Table 17.3 summarizes their current status [27]. Figure 17.7 shows their potential-current density behavior [28]. 

Carbon is only one atom in the periodic table. Why is carbon special From a chemical perspective, carbon forms covalent single, double, and triple bonds to another carbon and it forms covalent bonds to a variety of other atoms. This ability to bond with itself leads to an almost limitless number of organic molecules (molecules that contain carbon) and is one of the key reasons why the chemistry of carbon comprises an entire branch of chemistry. Millions of different molecules have covalent bonds to carbon. This chapter will discuss the structural features of a class of organic molecules that contain only carbon and hydrogen (hydrocarbons) and have no double or triple bonds. The chapter will also introduce a method for giving each different molecule an individual name. 

The simplest organic compounds are those of carbon and hydrogen— hydrocarbons—and the simplest hydrocarbon is methane, CH4, the chief constituent of natural gas.
