Butyric Aldehyde.—This body, C3H7COH, has been found in the oils of Eucalyptus globulus and Cajuput. It boils at 75° and forms a para-nitro-phenylhydrazone, melting at 91° to 92°.

It is noteworthy that even a separate treatment of the initial data on branched reactions (1) and (2) (hydrogenation of crotonaldehyde to butyr-aldehyde and to crotyl alcohol) results in practically the same values of the adsorption coefficient of crotonaldehyde (17 and 19 atm-1)- This indicates that the adsorbed form of crotonaldehyde is the same in both reactions. From the kinetic viewpoint it means that the ratio of the initial rates of both branched reactions of crotonaldehyde is constant, as follows from Eq. (31) simplified for the initial rate, and that the selectivity of the formation of butyraldehyde and crotyl alcohol is therefore independent of the initial partial pressure of crotonaldehyde. This may be the consequence of a very similar chemical nature of both reaction branches. 

Heating of cyclohexanone with N,N-dialkyltrimethylsilyl carbamates 544 a and 544b affords the enamines 545a and 545b in 55% and 50% yield, respectively [111]. More efficient, however, is the reaction of aldehydes such as n- or iso-butyr-aldehyde and ketones such as cyclopentanone or cyclohexanone with two equivalents of N-trimethylsilyldimethylamine 463 to give, either on heating [112] or at... 

Tetracaine Tetracaine, the 2-diethylaminoethyl ester of 4-butylaminobenzoic acid (2.1.6), is also structurally analogous to procaine, in which the amino group of the benzene ring is replaced by a butylamine radical. The methods for its synthesis are the same as the above-mentioned methods for procaine or chloroprocaine, with the exception of using 4-butylaminobenzoic acid in place of 4-aminobenzoic acid. There is also a proposed method of synthesis that comes directly from procaine (2.1.1). It consists on its direct reaction with butyric aldehyde and simultaneous reduction by hydrogen using a palladium on carbon catalyst [6]. 

PVA subsequently can be acetalised (reaction 6 in Fig. 2) with aldehydes, the most important of them being butyric aldehyde, leading to PVB. However, since PVB only plays a minor role, both according to the total volume produced and the number of applications that make use of PVB, it will not be discussed in much detail in this chapter. 

The reduction of butyric acid seems to proceed by way of n-butyr-aldehyde. The phytochemical reduction to butyl alcohol previously demonstrated for yeast (see p. 78) has also been carried out with bacteria. Regarding the reduction of butyric acid to n-butanol, papers of Bernhauer and coworkers, Kluyver and Donker, Stiles, Peterson and Fred, Janke and Siedler and Wood, Brown and Workman should be consulted. Peynaud ascribes also to wine yeast the ability to...

Reaction of poly (vinyl alcohol) [9002-89-5] with -butyr aldehyde yields poly(vinyl butyral) [63148-65-2] (PVB), a commercially important resin. 

Among important products manufactured in this manner are substituted propionaldehyde from corresponding substituted ethylene, normal and rso-butyr aldehyde from propylene, iso-octyl alcohol from heptene, and trimethylhexyl alcohol from di-isobutylene. 

The next breakthrough of importance for future 2-ethylhexa-nol plants occurred in the mid seventies. This was the development of the rhodium-catalyzed oxo process by Union Carbide, Davy Powergas and Johnson-Matthey (See Chapter 6). This process not only operates at lower temperatures and pressures than the conventional cobalt-catalyzed process but also gives a far lower yield of the less valuable isobutyraldehyde by-product. The net result is improved economics vs. the cobalt process for n-butyr-aldehyde - the intermediate for 2-ethylhexanol. Although outside the U.S. this new technology has already been licensed and plants are now operating(16), no new plants were constructed in the U.S. specifically for 2EH manufacture in the seventies. However,... 

The electrolysis of these three isomeric acids affords thus considerable qualitative differences in the results. Summing up the whole matter, it can be said that the electrolysis of a valeric acid gives octane, butyl valerate, butylene, butyl alcohol, and butyric aldehyde.

Vinylindole 68 was deprotected and the crude product, after purification, was reacted with a large excess of butyric aldehyde in MeCN in the presence of molecular sieves to give 13a and 13b and l,3-ethyl-2,3,4,5-tetrahydro-2-methyl-l,5-methano-l,3-diazocino[l,8- ]indole-6-nitrile 12a and 12b as a mixture of diastereomers (1 2 a-CN, /3-CN) (Equation 5). The formation of these products can be rationalized in terms of a domino process consisting of enamine formation, Michael addition, and Mannich reaction. When TFA was added directly to the reaction mixture, only 13a and 13b were obtained since 12a and 12b in acidic medium rearrange to 13a and 13b (see Section 14.05.2.4 (Equation 3) <1995S592>.
