Condensation of 2-quinolinecarboxaldehyde 98 with acetylacetone or ethyl acetate gave the acrylate derivatives 99 and 100, respectively. Cyclization of 99 with AC2O afforded the benzindolizine 101 (80ACSA(B)79). Reduction of 100 in presence of Adams catalyst followed by hydrolysis gave 102 (78PJC107) (Scheme 19).

Methyl acrylate (94.7 mg, 1.1 mmol) is added dropwise at room temperature to a suspension of morphinolone 132 (253 mg, 1 mmol), CsF (132 mg, 1 mmol), and Si(OMe)4 58 (150 pL) under argon. After stirring for 1 h the reaction mixture is subjected to flash chromatography on silica gel (eluent petroleum ether-ethyl acetate, 8 2) to afford a 1 1 mixture of isomers 133 (82% yield) as a colorless oil [68] (Scheme 3.18). 

Equation (23) was found to be obeyed by a number of systems such as poly(ethyl acrylate)-benzene, rubber-benzene, and poly(methyl acrylate)-ethyl acetate [12], According to the equation, a plot of [In(DT/D0)] l versus ([)[ will yield a straight line, and from its slope the free volume parameter p can be determined. To construct this plot,/( / , 0) is first calculated as [27]...

As a chemical raw material, ethanol is used for the production of a range of monomers and solvents, and is essential in pharmaceutical purification. In the presence of an acid catalyst ethanol reacts with carboxylic acids to produce ethyl esters. The two largest-volume ethyl esters are ethyl acrylate (from ethanol and acrylic acid) and ethyl acetate (from ethanol and acetic acid). Ethyl acrylate is a... 

The concentration of acrylic acid by extraction with ethyl acetate is a rather different illustration of this technique. As shown in Figure 13.4, the dilute acrylic acid solution of concentration about 20 per cent is fed to the top of the extraction column 1, the ethyl acetate solvent being fed in at the base. The acetate containing the dissolved acrylic acid and water leaves from the top and is fed to the distillation column 2, where the acetate is removed as an azeotrope with water and the dry acrylic acid is recovered as product from the bottom.

Polymerization of butyl acrylate was also studied by us in ethyl acetate/water two phase systems (3) using potassium persulfate/quaternary ammonium salts as the initiator system. Under these conditions (a minimum amount of water was used to dissolve the persulfate), it was found that symmetrical quat salts were more efficient than surfactant type quat salts. Also, the more lipophilic quat salts were more efficient. These results prompted us to propose formation of an organic-soluble quaternary ammonium persulfate via typical phase transfer processes. 

Items b and d may be related since the decrease in rate begins to be observed at about 40% conversion, i.e. at the point where [AN] has fallen to about 2.25 M. It is interesting to note that we ( ) and others ( 5) have also noted very slow rates of polymerization of ethyl acrylate at 1 M concentrations in ethyl acetate using either tetrabutyl ammoniurn bromide or 18-crown-6 as the phase transfer catalyst. Further studies in this area are needed. 

The complete transformation of a racemic mixture into a single enantiomer is one of the challenging goals in asymmetric synthesis. We have developed metal-enzyme combinations for the dynamic kinetic resolution (DKR) of racemic primary amines. This procedure employs a heterogeneous palladium catalyst, Pd/A10(0H), as the racemization catalyst, Candida antarctica lipase B immobilized on acrylic resin (CAL-B) as the resolution catalyst and ethyl acetate or methoxymethylacetate as the acyl donor. Benzylic and aliphatic primary amines and one amino acid amide have been efficiently resolved with good yields (85—99 %) and high optical purities (97—99 %). The racemization catalyst was recyclable and could be reused for the DKR without activity loss at least 10 times. 

Uses. Nearly half the ethyl alcohol produced in petrochemical plants (not the stuff fermented for human consumption) is used as a chemical intermediate in the manufacture of ethyl acrylate, ethyl amines, ethyl acetate (when you pop the cap on nail polish remover, you smell ethyl acetate), ethylene chloride, glycol ethers, acetaldehyde, and acetic acid. However, you will see in the chapters on acetaldehyde and acetic acid, there are now more competitive routes than those based on ethyl alcohol.

Several ester monomers have also been studied. In methanol solution, methyl acrylate (16,21), ethyl acrylate (21,54), 2-ethyl hexyl acrylate (55), allyl acrylate (44), glycidyl acrylate (56,57) usually in methanol solution, have been extensively studied. Methyl methacrylate (19, 21, 28, 30, 36, 39, 58) in diversified media composition, has been successfully grafted on polyamides. Vinyl acetate is reported also for grafting on polyamide backbone (19, 28, 35, 58), as well as n-butyl maleate in methanol solution (55). Diallyl maleate as cross-linking agent for polyamide chains is reported (44). Other less usual ester monomers have been mentioned in the literature to form grafts (41,59,60). 

Graft copolymers of polyamides using pre-irradiation gamma-rays techniques have been reported for styrene (130), in solution, in the presence of water (40), in alcohols or acetone solution (131), vinyl acetate (130), methacrylic acid in water (132) or methanol solution (129), methyl (133) and ethyl (130) acrylates, 2-ethylhexyl acrylate (55,134), methyl methacrylate (130), in methanol solution (129), 2-dimethylamino ethyl methacrylate quaternary salts (135), acrylamide in aqueous medium (128,136), acrylonitrile (130,137), and 4-vinyl pyridine in aqueous solution (128). 

Ethyl acetate is used in production of acrylic plastics. Ethyl acetate and butyl acetate find wide usage as solvents for nitrocellulose and lacquers. Hthyl acetate is considered one of the least toxic of all industrial organic solvents. Buiyl acetate s chief industrial competitor is methyl isobutyJ ketone. Over lime, ethyl acetate and butyl acetate may suffer the same fate as methyl acetate, which hos been largely displaced by other solvents.
