Nitrogen-containing base organic compounds

The M(/ -diketonate)2(polyether) compounds are normally white or colorless solids with good solubility in many organic solvents. As a group, they have the lowest melting points and sublimation temperatures, and therefore the best apparent volatilities, of any of the compounds discussed in this review.216 As noted previously, passing nitrogen-containing bases... 

The average composition of a base wine is given in Table 1. Wines can be viewed as hydroalcoholic solutions containing many organic compounds, some at concentrations as low as a few mg/L, which may show surface activity by themselves (nitrogenous monomers and polymers, e.g. aminoacids, proteins and glycoproteins, etc.) or by association with other compounds (polysaccharides associated with proteins, for example). It is not possible to decide which constituents are actually adsorbed at the surface and which one is the more foam active. 

There are a total of eighteen different hydrocarbon series, of which the most common constituents of crude oil have been presented - the alkanes, cycloalkanes, and the arenes. The more recent classifications of hydrocarbons are based on a division of the hydrocarbons in three main groups alkanes, naphthanes and aromatics, along with the organic compounds containing the non-hydrocarbon atoms of sulphur, nitrogen and oxygen. 

Animal metaboHsm is based on the reactions of oxygen and organic compounds containing carbon, hydrogen, oxygen, and nitrogen and other heteroatoms. Enzymes catalyze these biochemical oxidations, which are accompHshed at about 30—40°C and frequendy proceed stepwise to produce... 

The ease with which amines are extracted into aqueous acid, combined with their regeneration on treatment with base, makes it a simple matter to separate amines from other plant materials, and nitrogen-containing natural products were among the earliest organic compounds to be studied. Their basic... 

The basis of the demonstration can be based on already published data on the surface reaction between NOz and adsorbed organic compounds. Yokoyama and Misono have shown that the rates of N02 reduction over zeolite or silica are proportional to the concentration of adsorbed propene [29], whereas Il ichev et al. have demonstrated that N02 reacts with pre-adsorbed ethylene and propylene on H-ZSM-5 and Cu-ZSL-5 to form nitro-compounds [30], Chen et al [2-4] have observed the same nitrogen-containing deposits on MFI-supported iron catalysts. The question on the pairing of nitrogen atoms is not considered here. 

Landtreat is a silicate-based inorganic polymer catalyst used for the ex situ treatment of contaminated soils. The vendor claims that it acts as a catalyst to degrade halogenated compounds and organic compounds containing nitrogen and sulfur.
