Acetylation of acetaldehyde to ethyUdene diacetate [542-10-9], a precursor of vinyl acetate, has long been known (7), but the condensation of formaldehyde [50-00-0] and acetic acid vapors to furnish acryflc acid [97-10-7] is more recent (30). These reactions consume relatively more energy than other routes for manufacturing vinyl acetate or acryflc acid, and thus are not likely to be further developed. Vapor-phase methanol—methyl acetate oxidation using simultaneous condensation to yield methyl acrylate is still being developed (28). A vanadium—titania phosphate catalyst is employed in that process. 

Because the polymer degrades before melting, polyacrylonitrile is commonly formed into fibers via a wet spinning process. The precursor is actually a copolymer of acrylonitrile and other monomer(s) which are added to control the oxidation rate and lower the glass transition temperature of the material. Common copolymers include vinyl acetate, methyl acrylate, methyl methacrylate, acrylic acid, itaconic acid, and methacrylic acid [1,2].

Monomers which can add to their own radicals are capable of copolymerizing with SO2 to give products of variable composition. These include styrene and ring-substituted styrenes (but not a-methylstyrene), vinyl acetate, vinyl bromide, vinyl chloride, and vinyl floride, acrylamide (but not N-substituted acrylamides) and allyl esters. Methyl methacrylate, acrylic acid, acrylates, and acrylonitrile do not copolymerize and in fact can be homopolymer-ized in SO2 as solvent. Dienes such as butadiene and 2-chloro-butadiene do copolymerize, and we will be concerned with the latter cortpound in this discussion.

Copolymers. Vinyl acetate copolymenzes easily with a few monomers, e g, ethylene, vinyl chloride, and vinyl neodecanoate, which have reactivity ratios close to its own. Block copolymers of vinyl acetate with methyl methacrylate, acrylic acid, acrylonitrile, and vinyl pyrrolidinone have been prepared by copolymerization in viscous conditions, with solvents that are poor solvents for the vinyl acetate macroradical,... 

Porous silica is most widely used as adsorbent, but bonded phase materials with polar groups or crosslinked acrylonitrile39> have also been tested. Silica requires painstaking control of activity. In the separation of poly(styrene-co-methyl methacrylate) samples with dichloroethane—chloroform mixtures, clearer results were obtained with a silica column previously rinsed with methanol40. Continuously decreasing activity of silica columns was observed in the elution of poly(styrene-co-methyl acrylate) with CCU-methyl acetate mixtures38). 

Figure 8 shows the 259 nm UV record from the gradient elution of the mixture of three samples containing 46.6, 57.3, or 77.9 wt % methyl-acrylate units. This was the first report on copolymer separation by HPLC 38). The chromatogram was obtained on a silica column (600 x 7.5 mm, d0 = 5 nm dP = 15 pm) with a CCU/methyl acetate gradient (7-35 % in 35 min). In spite of the decaying activity of the column the composition distribution of the 57.3% sample could be evaluated.

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. 

Solvents account for 8% of methanol demand and include process uses such as extracting, washing, drying and crystallizing. Miscellaneous uses of methanol include the production of glycol methyl ethers, methyl acrylate and methyl acetate. Other uses include antifreeze, gasoline deicer, windshield washer fluid and hydrate inhibition in natural gas. 

Vinyl lacquers are used mainly where a high degree of chemical resistance is required these lacquers are based on vinyl chlorides and vinyl acetates. Acrylic lacquers are based on methyl methacrylate and methyl acrylate polymers and copolymers. Other esters of acrylic and methacrylic acid also may be used to make nonconvertible film formers. Judicious selection of these acrylic acid or methacrylic acid esters allows one to produce film formers with specifically designed properties such as hardness, flexibility, gloss, durability, heat, and chemical resistance. Acrylic lacquers, however, are not noted for their water resistance. The principal uses of acrylic-type lacquers are fluorescent and metallic paints, car refinish applications, clear lacquers and sealers for metals, and protective coatings for aircraft components and for vacuum-deposited metals, as well as uses in pigmented coatings for cabinets and appliances. 

Commercial production of acetic acid has been revolutionized in the decade 1978—1988. Butane—naphtha liquid-phase catalytic oxidation has declined precipitously as methanol [67-56-1] or methyl acetate [79-20-9] carbonylation has become the technology of choice in the wodd market. By-product acetic acid recovery in other hydrocarbon oxidations, eg, in xylene oxidation to terephthalic acid and propylene conversion to acrylic acid, has also grown. Production trom synthesis gas is increasing and the development of alternative raw materials is under serious consideration following widespread dislocations in the cost of raw material (see Chemurgy). 

Ethylene - vinyl acetate - acrylic acid teii)olymers have been crosslinked with 2,4 6-tri(2-methyl-l-aziridinyl)s-triazine or tris(2-methyl-l-aziridinyl) phosphite oxide. The in rovement in film tensile strength and the reduced solubility in triohlor ethylene are very marked. (49)... 

Moreover, poly(a-methylolbenzoin methyl ether acrylate) [poly(MBA)] has been checked in the UV induced polymerization of styrene and compared with poly(AB) and other low-molecular-weight structural models such as benzoin, a-methylol benzoin methyl ether (MBE) and a-methylol ben2 in methyl ether acetate (MBAc) [107].
