About 75% of the n-butyraldehyde generated is converted into 2-ethylhexanol, which is almost completely consumed as a phthalate ester, e.g., in plasticizers for PVC. The remainder of the butyraldehydes are either used as such for chemical synthesis, converted to acids or amines, or - more important today - hydrogenated to the butanols which are either directly sold as solvents or are further converted into acrylate esters, glycol ethers, butyl acetate, and butyl amines. [Pg.381]

Butanol is used to produce plasticizer-type esters like phthalates, phosphates, sebacates, oleates, and stearates. Two important ester derivatives, n-butyl acetate and n-butyl acrylate, used in the coating are produced from n-butanol. Glycol ether derivatives like ethylene glycol monobutyl ether (EB) used in the coating industry is the product of the n-butanol reaction with ethylene oxide in the presence of an acidic catalyst. Other important derivatives of n-butanol include butyl amines and butyl esters used as herbicides, butyl xanthate ore flotation aids, butylated urea, and melamine-formaldehyde resins. [Pg.90]

In contrast to this proposal, MacDonald et al. [64] su ested that the chain propagation of polymerization was a slow step, while Gross et al. [65] found that the monomer conversion followed first- order law and was independent of both the type (water, butanol and butyl amine) and concentration of the nucleophile. Yet another group suggested a complex mechanism of polymerization involving ring-opening and linear condensation polymerization [66]. [Pg.296]

In petroleum and oxygenate finish removers, the major ingredient is normally acetone, methyl ethyl ketone [78-93-3], or toluene. Cosolvents include methanol, / -butanol [71-36-3], j -butyl alcohol [78-92-2], or xylene [1330-20-7]. Sodium hydroxide or amines are used to activate the remover. Paraffin wax is used as an evaporation retarder though its effectiveness is limited because it is highly soluble in the petroleum solvents. CeUulose thickeners are sometimes added to liquid formulas to assist in pulling the paraffin wax from the liquid to form a vapor barrier or to make a thick formula. Corrosion inhibitors are added to stabili2e tbe formula for packaging (qv). [Pg.551]

Diazonium ions generated from ordinary aliphatic primary amines are usually useless for preparative purposes, since they lead to a mixture of products giving not only substitution by any nucleophile present, but also elimination and rearrangements if the substrate permits. For example, diazotization of n-butylamine gave 25% 1-butanol, 5.2% 1-Chlorobutane, 13.2% 2-butanol, 36.5% butenes (consisting of 71% 1-butene, 20% trans-2-butene, and 9% cw-2-butene), and traces of butyl nitrites. ... [Pg.448]

Full details on the phosphorylation of water and alcohols by 4-nitrophenyl dihydrogen phosphate and the NfC H ) - and N(CH3) -salts of its mono- and dianion have been published 146>. Phosphoryl group transfer from the monoanion and dianion is thought to proceed via the monomeric POf ion. Addition of the sterically unhindered amine quinuclidine to an acetonitrile solution containing the phosphate monoanion and tert-butanol produces t-butyl phosphate at a faster rate than does the addition of the more hindered diisopropylethylamine. This nucleophilic catalysis of the phosphorylation reaction is also explained by the intermediacy of the POf ion. [Pg.121]

The primary products obtained from 2-butanol are of mechanistic. significance and may be compared with other eliminations in the sec-butyl system 87). The direction of elimination does not follow the Hofmann rule 88) nor is it governed by statistical factors. The latter would predict 60% 1-butene and 40% 2-butene. The greater amount of 2-alkene and especially the unusual predominance of the cis-olefin over the trans isomer rules out a concerted cis elimination, in which steric factors invariably hinder the formation of cis-olefin. For example, the following ratios oicisjtrans 2-butene are obtained on pyrolysis of 2-butyl compounds acetate, 0.53 89, 90) xanthate, 0.45 (S7) and amine oxide, 0.57 86) whereas dehydration of 2-butanol over the alkali-free alumina (P) gave a cisjtrans ratio of 4.3 (Fig. 3). [Pg.84]

The orf/to-formylation of 2-aminopyridines can be effected via the rearrangement of the azasulfonium salt prepared from a 2-aminopyridine, 1,3-dithiane, f-butyl hypochlorite and sodium methoxide (74CC685). The crude sulfilimine (815) was refluxed in f-butanol containing potassium f-butoxide to yield the dithioacetal (816). Hydrolysis of (816) with mercury(II) oxide/boron trifluoride etherate gave the aldehyde (817 Scheme 191). This method should be applicable to the formylation of other heterocyclic amines. [Pg.490]

Robison, and Robison were the first to prepare 7-azagramine (3-dimethylaminoniethyl-7-azaindole), finding the following procedure to give optimum yields. The azaindole, 10% excess dimethyl-amine hydrochloride, and one molar equivalent of paraformaldehyde are refluxed together in w-butanol for 30 minutes, followed by evaporation under reduced pressure. The residue is extracted with dilute acid, from which the base is precipitated with sodium carbonate. This procedure has been used with only minor variations on a variety of 7-azaindoles. Williamson obtained 7-azagramine in 99% yield on a 0.2-mole scale, compared to 81%. Other 7-azagramines prepared similarly are l-phenyl-4-methyl (72%), ° l-butyl-4-methyl (64%), 6-chloro-4-methyl (60%), 4-methyl (28%), 2-methyl, and 5-methyl (60%). In the case of the last two 4-methyl compounds, it was found that the best yields were obtained with use of a 3 1 molar ratio of dimethylamine hydrochloride and only a 15-minute reflux period. With the 6-chloro-4-methyl isomer, some (6%) of the bis-(7-aza-3-indolyl)methylene by-product was formed. [Pg.62]

The acylal (4) can also be used to carry out reactions with nascent dimethylketene formed in situ. It is stable to t-butanol at the reflux temperature but with potassium carbonate present to ciitaly/,c cleavage it reacts smoothly to form /-butyl isobutyrate It reacts with an amine without other catalyst at room temperature to give an isohutyramide. In the presence of an alkali carbonate or the salt of a carboxylic acid, it converti an acid Into Its anhydride, probably via a mixed anhydride. With... [Pg.879]

No crystal was obtained from solutions of tert-butyl methyl ether (MTBE) and MTBE-EtOH, which were favorable solvents for the enantioseparation of racemic 3-(dimethylamino)-l-(2-thienyl)propan-l-ol with (S)-inandelic acid, or from other organic solvents, such as 2-butanol, ethyl acetate, ethyl methyl ketone and diethyl ether. In sharp contrast, fine crystals with acceptable diastereomeric purity (75%) deposited, when water was used as a solvent, although the yield was rather low (20%). The spectral and elemental analyses revealed that the salt crystallized from water was mono hydra ted the water molecules stabilizing the less-soluble diastereomeric salt crystal as a result of the close molecular packing with the amine and acid molecules. [Pg.144]

Starting from n-butyl (n-butyl a-o-mannopyranosiduronate) 4, uronamides 10 bearing a short butyl chain at the anomeric position and a longer alkyl (dodecyl, octadecyl, and oleyl) chain amide-linked to the sugar head were prepared following a one-step solvent-free procedure (Scheme 8). The aminolysis reaction was performed at 65°C to make the fatty amine liquid and under reduced pressure (3 mbar) to eliminate the butanol formed all through the reaction. To avoid significant... [Pg.156]
