Nitrous oxide characteristics

DNPT is a free flowing light yellow powder. Alone DNPT decomposes at approximately 190 °C and produces 265 cm3 of gas per gram at STP. Nitrogen, nitrous oxide, various amines and water are produced. In a rubber environment the gas generation takes place within a range of 130-190 °C. A characteristic amine fishy odour is quite pronounced and can be offensive for some applications. DNPT is non-staining.

The nitrous oxide-acetylene flame is both hot and reducing. A characteristic red, interconal zone is obtained under slightly fuel-rich conditions. This red feather is due to emission by the cyanogen radical. This radical is a very efficient scavenger for oxygen, thus pulling equilibria such as...

Nitrous oxide (N20) was first prepared by Priestly in 1772. Its anaesthetic properties were described by Sir Humphrey Davy in 1800 and it was first used in clinical practice by Colton and Wells in 1844. Physical characteristics... 

One of the most important factors influencing the transfer of an anesthetic from the lungs to the arterial blood is its solubility characteristics (Table 25-2). The blood gas partition coefficient is a useful index of solubility and defines the relative affinity of an anesthetic for the blood compared with that of inspired gas. The partition coefficients for desflurane and nitrous oxide, which are relatively insoluble in blood, are extremely low. When an anesthetic with low blood solubility... 

All of the above radicals are associated with a corresponding radical or element in a compound. While a radical frequently and rather generally enters into chemical reaction as a unit, it is not implied [hat this is always so, the stability in each case is characteristic of each radical and each reaction in which it is involved. Thus, ammonium hydroxide NH4OH yields ammonia gas NHr and water I liO at room temperature, ammonium nitrate NH4NO3 is decomposed, upon heating, with the accompanying disruption of both the ammonium and nitrate radicals 10 yield nitrous oxide NjO gas and water HiO... 

Nitrous oxide is difficult to categorize. Technically, it is an inhalant, yet there are several characteristics that set the drug apart from the typical volatile substances that inhalant abusers favor. First, N20 is not as readily accessible as hair spray, glue, household cleaners, and other off-the-shelf huffing chemicals of choice. Secondly, since nitrous oxide is an actual prescription anesthetic, it may have more perceived prestige among users who would look down at most volatile substance abuse as kid s stuff. ... 

This type of active site is also known as a mixed-valence copper site. Similarly to the type 3 site, it contains a dinuclear copper core, but both copper ions have a formal oxidation state of +1.5 in the oxidized form. This site exhibits a characteristic seven-line pattern in the EPR spectra and is purple colored. Both copper ions have a tetrahedral geometry and are bridged by two sulfur atoms of two cysteinyl residues. Each copper ion is also coordinated by a nitrogen atom from a histidine residue. The function of this site is long-range electron transfer, and it can be found, for example, in cytochrome c oxidase [12-14], and nitrous oxide reductase (Figure 5.1 e). 

Morpholine is a colorless hygroscopic liquid, with a characteristic odor It decomposes on heating and produces nitrous oxides. It is a base that reacts violently with acids, and it is corrosive to aluminum, zinc and copper. Morpholine reacts with oxidants and nitrites. In addition, the carcinogenic N-nitrosomorpholine can be formed from nitrosation of morpholine248. 

The third class consists of proteins that are composed of one or more BCB domains fused to a sequence domain(s) characteristic of evolutionarily unrelated protein families. Such a mosaic domain organization has been found in the phytocyanin protein family, stellacyanins, uclacyanins, and the recently characterized dicyanins (Section V) in blood coagulation factor VIII (Section VIII) and in nitrous oxide reductase (Section IX).
