Nitrogen-containing

Contaminants such as the sulfur and nitrogen contained in the effluent gas are directly dependent on the feedstock properties. [Pg.385]

Outline the laboratory preparation of a sample of dinitrogen tetroxide. Describe and explain what happens when it is heated from 290 K to 900 K. Suggest electronic structures for dinitrogen tetroxide and the other nitrogen-containing molecules formed from it on heating to 900 K. Point out any unusual structural features. [Pg.255]

The organic chemical structural types believed to be characteristic of coals include complex polycyclic aromatic ring systems with connecting bridges and varied oxygen-, sulfur-, and nitrogen-containing functionalities. [Pg.132]

A completely different, important type of synthesis, which was developed more recently, takes advantage of the electrophilicity of nitrogen-containing 1,3-dipolar compounds rather than the nucleophilicity of amines or enamines. Such compounds add to multiple bonds, e.g. C—C, C C, C—O, in a [2 + 3 -cycioaddition to form five-membered heterocycles. [Pg.152]

Mills and Smith (504) were the first, in 1922, to develop a systematic study of the reactivity of methyl groups fixed on nitrogen-containing heterocycles. While in alkylpyridines the 2- (or 6) and 4-positions are activated, only the 2-position in thiazole corresponds to an enhanced reactivity of the methyl groups in condensation with aldehydes 4- and 5-methylthiazoles bear inert methyl groups. Quatemization of the thiazole nitrogen enhances still further the reactivity of the methyl in the 2-position (cf. Chapter IX), but it does not increase the reactivity of a methyl group in the 4-position (504). The authors invoke the possibility for 2- (and 6) methylpyridine and 2-methylthiazole to pass, to some extent, into the reactive enamine form (245), while 4-methylthiazole could adopt such a structure only with the participation of an unusual formula such as 247 (Scheme 112). [Pg.143]

It is well known that in nitrogen-containing heterocyclic compounds the reactivity of alkyl groups is enhanced. In the thiazole series, alkyl groups in the 2-position are reactive towards carbonyl compounds and condensations may be realized. [Pg.392]

Many nitrogen containing compounds engage in a proton transfer equilibrium that is anal ogous to keto-enol tautomensm... [Pg.789]

Given a nitrogen containing organic compound such as an amide a nitnle or a nitro compound how is the correct oxidation state of the desired amine to be achieved" ... [Pg.926]

Almost any nitrogen containing organic compound can be reduced to an amine The syn thesis of amines then becomes a question of the availability of suitable precursors and the choice of an appropriate reducing agent... [Pg.931]

Atmospheric nitrogen containing 98.815% N2 by volume + 1.185% inert gases. [Pg.366]

Tetrahydrofurfuryl alcohol reacts with ammonia to give a variety of nitrogen containing compounds depending on the conditions employed. Over a barium hydroxide-promoted skeletal nickel—aluminum catalyst, 2-tetrahydrofurfur5iarnine [4795-29-3] is produced (113—115). With paHadium on alumina catalyst in the vapor phase (250—300°C), pyridine [110-86-1] is the principal product (116—117) pyridine also is formed using Zn and Cr based catalysts (118,119). At low pressure and 200°C over a reduced nickel catalyst, piperidine is obtained in good yield (120,121). [Pg.82]

Although acetonitrile is one of the more stable nitriles, it undergoes typical nitrile reactions and is used to produce many types of nitrogen-containing compounds, eg, amides (15), amines (16,17) higher molecular weight mono- and dinitriles (18,19) halogenated nitriles (20) ketones (21) isocyanates (22) heterocycles, eg, pyridines (23), and imidazolines (24). It can be trimerized to. f-trimethyltriazine (25) and has been telomerized with ethylene (26) and copolymerized with a-epoxides (27). [Pg.219]
