Another significant appHcation for amyl alcohols is for production of amyl acetates. Production of amyl acetates in 1987 is estimated to have been 4.5-5.5 X 10 t about 50% of the domestic demand is for lacquers (150). Union Carbide Chemicals and Plastics Company Inc. is the only U.S. producer. 

The principal component of primary amyl alcohol, 1-pentanol, although itself a good solvent, is useful for the preparation of specific chemicals such as pharmaceuticals and other synthetics (153,154). Production of primary amyl acetate and its esters for solvent appHcations has seen low growth since the 1970s because of the decline of nitroceUulose lacquers and the introduction of new solvent systems. 

Riboflavin forms fine yellow to orange-yeUow needles with a bitter taste from 2 N acetic acid, alcohol, water, or pyridine. It melts with decomposition at 278—279°C (darkens at ca 240°C). The solubihty of riboflavin in water is 10—13 mg/100 mL at 25—27.5°C, and in absolute ethanol 4.5 mg/100 mL at 27.5°C it is slightly soluble in amyl alcohol, cyclohexanol, benzyl alcohol, amyl acetate, and phenol, but insoluble in ether, chloroform, acetone, and benzene. It is very soluble in dilute alkah, but these solutions are unstable. Various polymorphic crystalline forms of riboflavin exhibit variations in physical properties. In aqueous nicotinamide solution at pH 5, solubihty increases from 0.1 to 2.5% as the nicotinamide concentration increases from 5 to 50% (9). 

Esters of medium volatility are capable of removing the water formed by distillation. Examples are propyl, butyl, and amyl formates, ethyl, propyl, butyl, and amyl acetates, and the methyl and ethyl esters of propionic, butyric, and valeric acids. In some cases, ternary azeotropic mixtures of alcohol, ester, and water are formed. This group is capable of further subdivision with ethyl acetate, all of the ester is removed as a vapor mixture with alcohol and part of the water, while the balance of the water accumulates in the system. With butyl acetate, on the other hand, all of the water formed is removed overhead with part of the ester and alcohol, and the balance of the ester accumulates as a high boiler in the system.

Amyl Acetate.—This is, with the exception of amyl formate, which is not of practical importance, the simplest possible ester of amyl alcohol, and has the formula CHj. COO. CsHjj. It is a fruity oil, with a strong odour resembling that of the pear, and is known as art ficial oil of pear. It is prepared on a very large scale by, for example, treating 100 parts of dry sodium acetate, 100 parts of amyl alcohol, and 130 parts of sulphuric acid for twelve hours at ordinary temperature, and then distilling off the ester. It has a specific gravity 0-876, and boils at 138°. The alcohol in this ester is not normal amyl alcohol, but isoamyl alcohol.

The first dip given to a fusehead is known as the flashing composition and is of particular importance. Originally copper acetylide was used for this purpose, but it has been superseded by more stable materials. Three common compositions are based on lead picrate, lead mononitroresorcinate and a mixture of charcoal and potassium chlorate respectively. These materials are suspended in a solution of nitrocellulose in amyl acetate and amyl alcohol, known as Zapon. One or more dips, with intermediate drying, give a layer of suitable thickness.

Benzyl alcohol can be smoothly converted to benzaldehyde by electrochemi-cally recycled BrO as an oxidizing catalyst in an emulsion system prepared from a mixture of water, amyl acetate, and 2% BU4NHSO4 [60]. A different hypobromite reagent is provided by an electrochemical oxidation of a cross-linked poly-4-vinylpyridine in an MeCN-H20-HBr-(Pt) system [61]. Secondary alcohols can be oxidized by this method to give ketones in high yields. The electrooxidation of A-monoalkyltosylamides (42) in a two-phase system consisting of cyclohexane...

Behavioral thresholds for w-butyl acetate and n-butyl alcohol in the tiger salamander (Am6jito/na ft n BM/n) were 8.9 x 10 and 6.7 x 10 mol/1, respectively (Mason and Stevens, 1981b). The threshold for amyl acetate has been measured as 10 " mol/1 in frogs and 10 mol/1 in turtles (Enomoto etal., 1992).

The largest offtake of acetone is its conversion into solvents, used mainly in lacquers and other synthetic resin applications. These solvents include diacetone alcohol, methyl isobutyl ketone, methyl isobutyl carbinol (methyl amyl alcohol), and methyl amyl acetate. The following equations (22), in each of which the raw material is the product of the previous reaction, show a possible procedure by which these solvents may be made ... 

Objects molded from classic ABS or ASA copolymers are generally severely attacked by numerous chemical products, such as acids like acetic acid, butyric acid, and nitric acid, phthalates like dioctyl phthalate, gasoline, greases, inks, iodine, alcohols like methanol, motor oils, phenols, glycols, tetrachloroethylene, and acetates like ethyl acetate, amyl acetate, and others (29). 

Amyl Acetate or Amylacetic EsteKcommonly known as Banana Oil),C H. COOCH, mw 130.18- Several isomers are known of which n-amyl acetate and isoamyl acetate are the most important. They can be prepd by heating amyl alcohols with acetic acid in the presence of some sulfuric acid. Industrial methods of prepn are given in Ref 9,pp 102—3- Commercial products are usually mixts of n- and iso-amyl acetates. When amyl acetate is prepd from "fusel oil (a byproduct obtained in the manuf of ethyl ale by fermentation), the chief component is isoamyl acetate...

Kruger [113] tried fractionating nitrocellulose by diffusion. The principle of the method was that a nitrocellulose solution in acetone, methyl alcohol or amyl acetate diffused into a pure solvent layer on the surface of the solution. Clearly molecules of smaller size penetrate more rapidly. A nitrocellulose solution of 12.8% N was separated into two layers in this way after 42 days diffusion. The lower fraction comprised nitrocotton with a nitrogen content of 13.1% N, the upper layer one of 12.1% N.
