A mixture of calendic acid methyl ester 1 (3 mmol, 1.50 g) and maleic anhydride (5 mmol, 0.49 g) was heated for 2h at 150 °C under nitrogen. The reaction was followed by thin-layer chromatography [petroleum ether-diethyl ether (7 3), Rf 1=0.60, Rf 3=0.23], Purification of product 3 was achieved by column chromatography [silica gel using petroleum ether/diethyl ether (7 3) and petroleum ether/ethyl acetate (1 1) as eluent]. Fractions containing product 3 were collected and the solvent was removed in vacuo. Compound 3 was recrystallized from petroleum ether/diethyl ether (4 1).

In the THM-GC profile of the printing ink resin,dimethyl fumarate (peak 6) is detected, suggesting the presence of maleic or fumaric acid. Pentaerythritol is indicated by the presence of the tetra- and trimethyl ethers (peaks 7 and 8, respectively). Tertiary butyl phenol and methyl and dimethyl tertiary butyl phenols are detected as their methyl ethers (peaks 9, 10, and 11, respectively). Rosin acid methyl esters are detected with dehydroabietic acid and abietic acid methyl esters predominating (peaks 15 and 16, respectively). This resin is therefore diagnosed...

This chapter describes the production of mild surfactants based on fatty acids, fatty acid methyl esters, and fatty alcohols from the oleochemistry in combination with petrochemical compounds such as alkanolamines, maleic acid anhydride, or glucose/glucose derivatives.

Krilium The trade name of a soil conditioner. The solid form of Krilium has as active in-gredienl a copolymer of about equal molar proportions of vinyl ethanoate and the partial methyl ester of maleic acid. It may be formulated with lime, bentonite, etc. In aqueous form, Krilium contains a copolymer of about equal molar proportions of isobutene and ammonium maleamate. Other polymers are also used.

Acetanilide and maleic acid are condensed to give /3-(p-acetaminoben2oyl)acrvlic acid which is hydrogenated to give methyl- y-(p-aminophenyl)butyrate. That is reacted with ethylene oxide and then with phosphorus oxychloride to give the methyl ester which is finally hy-droly2ed to give chlorambucil. 

Experimental studies of the adsorption of polyelectrolyte have been reported by several authors Pefferkom, Dejardin, and Varoqui (3) measured the hydrodynamic thickness of an alternating copolymer of maleic acid and ethyl vinyl ether adsorbed on the pore walls in cellulose ester filter as a function of the molecular weight and the concentration of NaCl. Robb et al. (4) studied the adsorption of carboxy methyl cellulose and poly (acrylic acid) onto surfaces of insoluble inorganic salts. However, their studies are limited to the measurements of adsorbance and the fraction of adsorbed segments.

Films for lithographic evaluation were cast from methyl cellosolve acetate, and prebaked at 120°C in a vacuum oven for one hour. Patterns were developed using mixtures of ethyl cellosolve acetate and methyl cellosolve acetate. Areas exposed at a dose of 80 / 2 (20 keV) were developed with about 10% thinning of the unexposed resist. For development at 100 / 2, a contrast of 2.1 was observed (Figure 2), and the resolution at this dose was limited to about one micron. Superior sensitivity and resolution were obtained using a MA-AMS copolymer formed on the wafer by prebaking a copolymer of the methyl half ester of maleic acid with alphamethylstyrene. This latter resist system is discussed a little later.

Diels-Alder Reaction. By means of the Diels-Alder reaction a considerable number of hydrobiphenyls have been prepared,486 from which it should be possible to obtain unsymmetrical biaryls by dehydrogenation. Only a few of the adducts have been converted to the completely aromatic compounds. o-Terphenyl has been prepared from the adduct of maleic anhydride and 3,4-diphenylcyclopentadienone,436 and p-terphenyl has been obtained in practically quantitative yield from the adduct of the methyl ester of acetylenedicarboxylic acid and 1,4-diphenylbutadiene.43d...
