Organic thiocyanates (R = carbon) can be readily prepared by a wide range of methods, most commonly by the formation of the RS bond or, to a lesser degree, the SCN bond. The most recent review of their syntheses was by Guy <B-77MI 530-02>. This section will deal mostly with...
For acidic conditions, which generally occur when in addition to the presence of the sulfate, SO3gas (in presence of oxygen, SO2is catalytically converted to SO3) is available, the sulfate salt reacts with the protective oxide scale, such as Al2O3, on the alloy: ...
CH3ONa is used to initiate anionic addition polymerization of ethylene oxide. This produces a polyether having a high molecular weight. It can also be used for processing edible oils and fats and also in the preparation of other chemicals. ...
Analysis of gaseous products indicated that all of the NO that is depleted by reaction with Na 2CO 3 is converted to oxygen (02) and nitrogen (N2). For Na2CO 3/Na2S mixtures, no oxygen could be detected in the gas stream. It was shown that the oxygen formed by depletion of NO was...
In its place, a rapid reaction occurred, consuming Hand NaNand producing N, NH, Na, and probably NaNH.Both systems were complex and probably best described as concerted reactions between the azide and the added gas rather than reactions of NO or Hwith transient nitrogen species formed in the...
When molten sodium is involved in a fire, the combustion occurs at the surface of the liquid. An inert gas, such as nitrogen or argon, can be used to form an inert layer over the pool of burning liquid sodium, but the gas must be applied very gently and contained over the surface. ...
Hazardous Decomposition Products: It emits Carbon oxides, sodium oxide and toxic fumes when heated to decomposition. Hazardous Polymerization: Will not occur. Incompatibilities: Oxidizing agents. Conditions to Avoid: Avoid moisture, heat, sparks, open flames and other ignition sources. Contact with inc...
Regulation of tomato lateral root development by carbon monoxide and involvement in auxin and nitric oxide Carbon monoxide (CO) is an endogenous gaseous molecule in organisms. Despite its reputation as a lethal gas, recent studies have shown that it is one of th... Kai Guo, Kai Xia and Zhi...

("borate" for brevity), and silicon. Borate is exemplified by boric acid, or other compound with a B--O bond, such as sodium tetraborate, sodium fluoborate, and the like, which compound is at least slightly soluble in the melt, and which also yields a reactive boron oxide when the ...
