Cellulosics. CeUulosic adhesives are obtained by modification of cellulose [9004-34-6] (qv) which comes from cotton linters and wood pulp. Cellulose can be nitrated to provide cellulose nitrate [9004-70-0] which is soluble in organic solvents. When cellulose nitrate is dissolved in amyl acetate [628-63-7] for example, a general purpose solvent-based adhesive which is both waterproof and flexible is formed. Cellulose esterification leads to materials such as cellulose acetate [9004-35-7], which has been used as a pressure-sensitive adhesive tape backing. Cellulose can also be ethoxylated, providing hydroxyethylceUulose which is useful as a thickening agent for poly(vinyl acetate) emulsion adhesives. Etherification leads to materials such as methylceUulose [9004-67-5] which are soluble in water and can be modified with glyceral [56-81-5] to produce adhesives used as wallpaper paste (see Cellulose esters Cellulose ethers). 

In addition to high aqueous solubility (7% at 30°C and 38% at 100°C), HgCl2 is very soluble in methyl alcohol (53% at 36°C), ethyl alcohol (34% at 31°C), and amyl alcohol (ca 10% at 30°C). It also is soluble in acetone, formic acid, the lower acetate esters, and other polar organic solvents. 

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. 

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.

Isotopic substitution. A classic example is the demonstration by Polanyi and Szabo (37) of acyl-oxygen fission in the alkaline hydrolysis of -amyl acetate. An ester could undergo cleavage at two locations, as indicated in 3. 

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.

Organic acid esters carbonates (e.g. ethyl carbonate), formates, acetates (e.g. ethyl acetate, butyl acetate, amyl acetate), propionates, etc., oxalates (e.g. ethyl oxalate), maleates, phtha-lates (e.g. butyl phthalate) carbamates and phenylcarbamates (e.g. ethyl phenylcarbamate). 

Marqueyrol and Florentin point out that the lower members of the series of esters, the acetates, butyrates, valerates, etc., are good solvents for nitrocellulose—ethyl and amyl acetate have long been used for the purpose—but the higher members, the stearates and oleates, gelatinize nitrocellulose but very little. To the esters of the dibasic acids the opposite rule appears to apply the higher members are better than the lower. Acetone is a well-known solvent both for soluble and for insoluble nitrocellulose, but acetophenone gelatinizes even soluble nitrocellulose only feebly. 

The acetates of most alcohols are also commercially available and have diverse uses. Because of their high solvent power, ethyl, isopropyl, butyl, isobutyl, amyl, and isoamyl acetates are used in cellulose nitrate and other lacquer-type coatings (see CELLULOSE, esters). Butyl and hexyl acetates are excellent solvents for polyurethane coating systems (see Coatings Urethane polymers). Ethyl, isobutyl, amyl, and iso amyl acetates are frequendy used as components in flavoring (see Flavors AND SPICES), and isopropyl, benzyl, octyl, geranyl, linalyl, and methyl acetates are important additives in perfumes (qv). 

Amyl Acetate or Amylacetic Ester(commonly known as Banana Oil),C5 Htl.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 raanuf of ethyl ale by fermentation), the chief component is isoamyl acetate...
