Hydrogen Sulfide

A complete guide to the most important reduction method in organic synthesis The most comprehensive reference in the field, Handbook of Heterogeneous Catalytic Hydrogenation for Organic Synthesis provides synthetic chemists and chemical engineers in fine chemicals and pharmaceuticals with detailed experimental guidelines for heterogeneous catalytic hydrogenation. Organized by functional groups for ready reference and featuring detailed examples of hundreds of reactions, this handbook covers hydrogenations of alkenes, alkynes, aldehydes and ketones, nitriles, imines, nitro and nitroso compounds, carboxylic acids and esters, and aromatic and heterocyclic compounds. In addition, coverage includes the preparation of amines by reductive alkylation and the hydrogenolysis of a variety of compounds. Examples of hydrogenation of functional groups and reaction pathways are illustrated with numerous equations and schemes. Practitioners will appreciate the plenitude of experimental details given for most of the reactions selected, including amounts of reagents and catalysts, reaction temperatures, hydrogen pressures, and reaction times. They will also find helpful the more than one hundred tables included throughout the book detailing the effects of key factors governing rate and selectivity, such as compound structure, the nature of catalysts and supports, and the nature of solvents. Researchers will benefit from the introductory chapters covering an array of hydrogenation catalysts, including nickel, cobalt, copper, iron, platinum group metals, rhenium, and other oxide and sulfide catalysts, as well as reactors and reaction conditions.

Hydrogen sulfide - Hydrogen sulfide (hydrogen sulphide in [[British Engl

Ammonium sulfide - Ammonium sulfide, (NH4)2S, is obtained, in the form of micaceous crystals, by passing hydrogen sulfide mixed with a slight excess of ammonia through a well-cooled vessel; the hydrosulfide NH4•HS is formed at the same time. It dissolves readily in water, but is probably partially dissociated in solution.

Hydrogen selenide - Hydrogen selenide, H2Se, is a colorless gas with a melting point of -66oC and a boiling point of -42oC, and a density of 2120kg/m3 as a liquid. Its toxicity is similar to that of hydrogen sulfide.

Sulphide stress cracking - Sulphide stress cracking (SSC), or sulphide stress corrosion cracking (SSCC), is a special corrosion type, a form of stress corrosion cracking. Susceptible alloys, especially steels, react with hydrogen sulfide, forming metal sulfides and elementary hydrogen, which gets absorbed in metal and leads to hydrogen embrittlement.

Liquid Hydrogen Storage - Liquid Hydrogen Storage Liquid nitrogen economy - A liquid nitrogen (LN2) economy is a hypthetical proposal for a future economy in which the primary form of energy storage and transport is liquid nitrogen. It is proposed as an alternative to liquid hydrogen in some transport modes and as a means of locally storing energy captured from renewable sources. Liquid hydrogen - Liquid hydrogen is a common liquid rocket fuel for rocket applications. In the aerospace industry, its name is often abbreviated to LH2. ...

Gas Hydrogen Production - Gas Hydrogen Production Floating Production Storage and Offloading - A Floating Production, Storage and Offloading vessel (FPSO; also called a "unit" and a "system") is a type of floating tank system used by the offshore oil and gas industry and designed to take all of the oil or gas produced from a nearby platform (s), process it, and store it until the oil or gas can be offloaded onto waiting tankers, or sent through a pipeline. A FSO is a similar system, but without the possibility to do any processing ... Hydrogen grooving - In the chemical industry, hydrogen grooving is the corrosion of piping by grooves created by the interaction of a corrosive agent, corroded pipe constituents, and hydrogen gas bubbles. By example, when sulfuric acid (24) flows through steel pipes, ...
