Butyric Aldehyde


Poly(vinyl alcohol) participates in chemical reactions in a manner similar to other secondary polyhydric alcohols (82—84). Of greatest commercial importance are reactions with aldehydes to form acetals, such as poly(vinyl butyral) and poly(vinyl formal).  [c.480]

Thus, -butyl [71-36-3] [71-36-3] and isobutyl alcohol [78-83-1] [78-83-1] are obtained by hydrogenation of their respective aldehydes and butyric and isobutyric acid are produced by oxidation.  [c.378]

Although tests have shown that / -butyraldehyde exhibits some adverse physiological effects, there is no danger to health in normal plant practice. No threshold limit value has been assigned for either butyraldehyde or isobutyraldehyde. Both aldehydes, however, have a pungent, penetrating odor. Their vapors as well as the neat Hquids can cause skin, eye, and respiratory organ irritation possibly because of rapid oxidation to the acids on contact with air. Because of the ease of oxidation of the butanals to the corresponding butyric acids, precautions associated with these carboxyUc acids must also be noted. Reported animal toxicity and irritancy values for the butanals are given in Table 6.  [c.381]

The products are amorphous resins whose rigidity and softening point depend on the aldehyde used. Poly(vinyl butyral), with the larger side chain, is softer than poly(vinyl formal). Since the reaction between the aldehyde and the hydroxyl groups occurs at random, some hydroxyl groups become isolated and are incapable of reaction. A poly(vinyl acetal) molecule will thus contain  [c.392]

Polyvinyl acetate and derivatives Polyvinyl acetate is used largely for coating applications, but the derivative polyvinyl alcohol, will, providing there are some residual acetate groups, dissolve in water. Reaction products of polyvinyl alcohol with aldehydes such as polyvinyl formal and polyvinyl butyral are highly specialised materials.  [c.932]

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°.  [c.180]

It IS hard to find a class of compounds in which the common names of its members have influenced organic nomenclature more than carboxylic acids Not only are the common names of carboxylic acids themselves abundant and widely used but the names of many other compounds are derived from them Benzene took its name from benzoic acid and propane from propionic acid not the other way around The name butane comes from butyric acid present m rancid butter The common names of most aldehydes are derived from the common names of carboxylic acids—valeraldehyde from valeric acid for exam pie Many carboxylic acids are better known by common names than by their systematic ones and the framers of the lUPAC rules have taken a liberal view toward accepting these common names as permissible alternatives to the systematic ones Table 19 1 lists both common and systematic names for a number of important carboxylic acids  [c.792]

The common method of naming aldehydes corresponds very closely to that of the related acids (see Carboxylic acids), in that the term aldehyde is added to the base name of the acid. For example, formaldehyde (qv) comes from formic acid, acetaldehyde (qv) from acetic acid, and butyraldehyde (qv) from butyric acid. If the compound contains more than two aldehyde groups, or is cycHc, the name is formed using carbaldehyde to indicate the functionaUty. The lUPAC system of aldehyde nomenclature drops the final e from the name of the parent acycHc hydrocarbon and adds al If two aldehyde functional groups are present, the suffix -dialis used. The prefix formjlis used with polyfunctional compounds. Examples of nomenclature types are shown in Table 1.  [c.469]

Cy—oxo-derived acids are the principal derivatives of the C —oxo aldehydes, and ia analogy to oxo aldehyde market appHcations, are used chiedy to make neopolyol esters, ie, those based on neopentyl glycol, trimethylolpropane, or pentaerythritol. These synlubes are employed almost entirely ia aeromotive appHcations. Heptanoic acid is also employed to make tetraethylene glycol diheptanoate, a plasticizer used with poly(vinyl butyral).  [c.473]

Composition, Processing, and Uses. There are no statistics available for the amount of wood tar processed, but almost all of it is burned. The commercial by-products from wood carbonization are limited to methanol, denatured methanol, methyl acetate, and acetic acid. These products are derived from the aqueous phase of the condensed products, the so-called pyroHgneous acid. On distillation, pyroHgneous acid yields wood spirit, acetic acid having small amounts of propionic and butyric acids, and soluble tar. The wood spirit, on refining, yields methanol as weU as methyl acetate and acetone. The aqueous acid fraction is neutralized with milk of lime to give gray acetate of lime, 82—84% (CH2COO)2Ca, which is neutralized to give acetic acid or pyrolyzed to give acetone. The soluble tars are mainly condensation products of aldehydes and phenols they are burned as fuel.  [c.335]
