Van Helmont, the most prominent of the seventeenth-century iatro-chemists, made the acid-alkali reaction the chemical model for a theory of animal digestion. One of his pupils, Sylvius by name, carried this idea into a total system by claiming that all bodily functions were acid-alkali reactions, and that all body fluids were either acidic or alkaline. This theory... 

Fiber-Reactive Dyes. These dyes can enter intu chemical reaction with the fiber and form a covalent bond to become an integral part of the liber polymer. They therefote have exceptional wetfastness. Their main use is oil eellulosie fibers where they are applied neutral and then chemical reaction is initialed by the addition of alkali. Reaction with the cellulose can be by either nucleophilic substitution, using, for example, dyes containing activated halogen substituents, or by addition to the double bond in. for example, vinyl sulfone. -SCfCH=CH2, groups.

The reaction should be compared with the simultaneous oxidation and reduction of aromatic aldehydes under the influence of concentrated caustic alkali (Reaction LXIII.). 

There are various processes for synthesizing hydroxyapatite in aqua phase, such as hydrolyzation [223], acid-alkali reaction [224], hydrothermal process [225], coprecipitation [226], sol-gel synthesis [227], aerosol pyrolysis [228], and micro emulsion synthesis [229], etc. 

Oxazoles give acylamino ketones 232 by acid-catalyzed ring scission, although they are somewhat more stable than furans. The oxazole ring is also moderately stable to alkali reaction with hydroxide ions is facilitated by electron-withdrawing substituents and fused benzene rings.

Lemery s defense of the five principles and his corpuscular account of the acid-alkali reactions (quoted above) raise the possibility that he was aware of Boyle s critique of chemists principles and of the acid-alkali theory. As a leading Protestant apothecary employed in the royal household, Lemery should have been acquainted with other Protestant chemists in Paris. He returned to Paris in 1672, soon after Du Clos s critique of Boyle caused a stir within the Academy. He also knew Wilhelm Homberg, who had worked briefly in Boyle s laboratory. " It seems quite likely that Lemery incorporated Boyle s critique of chemical principles into the French didactic tradition, creating a unique blend of chemical philosophy. His limited yet flexible use of the corpuscular imagery illustrates well the fluidity of French didactic discourse in accommodating the current philosophical fashion. 

The sulfonamides are distinguishable because the derivative from a primary amine has an acidic hydrogen, which renders the product soluble in alkali (reaction 1) whereas the sulfonamide from a secondary amine is insoluble (reaction 2). Tertiary amines lack the necessary acidic hydrogen for formation of benzenesulfonyl derivatives. 

Three structurally isomeric forms have been established for the six-carbon saccharinic acids. In the order of their discovery, these are the sac-charinic or 2-C -methylpentonic acids, the isosaccharinic or 3-deoxy-2-C -(hydroxymethyl)-pentonic acids, and the metasaccharinic or 3-deoxy-hexonic acids. Although none of these six-carbon, deoxyaldonic acids has been crystallized, six are known in the form of crystalline lactones (saccharins). All the possible metasaccharinic acids of less than six-carbon content have been obtained, in the form of crystalline derivatives, by the sugar-alkali reaction. Only one example of a branched-chain deoxyaldonic acid (the racemic, five-carbon isosaccharinic acid) of other than six-carbon content has been so obtained. The formation of saccharinic acids containing more than six carbon atoms remains to be explored. 

Only the racemic form of this acid is obtained from the sugar-alkali reaction. As in the formation of lactic acid, a non-asymmetric enediol is an intermediate in its production (see Section III), and hence the racemate is the sole representative of the four-carbon metasaccharinic acid class. 

This recently discovered, racemic acid of the five-carbon aeries is only the third example of an isosaccharinic acid to be identified as a product of the sugar-alkali reaction. The other examples are the a- and /3-D-isosac-charinic acids of the six-carbon aeries (see pages 48 and 52). 

These four acids comprise all the possible five-carbon metasaccharinic acids and all were obtained by Nef, in the form of crystalline derivatives, from the pentose-alkali reaction.
