Acetal terminology

If we look again at Equation 3.3, we can see that we should consider the reverse process as an acid-base reaction just as the forward process is. The acetate ion is a base that can accept a proton from the acid HaO+. This reciprocal relationship is emphasized by the terminology applied to processes like that in Equation 3.3 Acetate ion is called thp mnjuont.e hate. of the acid CH3CQQH. and HoO+ is called the coniueate acid of the base HoQ. 

Fig. 1.14. NaBH4, reduction of (/Thydroxyalkyl)mercury(II) acetates to alcohols and radical fragmentation of (/f hydroxy-alkyl)mercury (II) hydrides. According to the terminology used in Figure 1.2 it is a "substitution by fragmentation."...

Scheme Effective charge map for the alkaline hydrolysis of aryl acetate esters. Both Bronsted and Hammett terminologies are illustrated but this makes no difference to the magnitude of either Leffler s a or the effective charges...

The degree of hydrolysis of poly(vinyl alcohol) influences the emulsion polymerization of vinyl acetate. The lower the degree of hydrolysis, the better the emulsifying action of the protective colloid and the faster the rate of polymerization [146]. In coimection with this statement we must point out that the terminology a poly(vinyl alcohol) of low degree of hydrolysis is widely... 

Sulfur acetals as good nucleophiles in the terminology of chapter 28, acyl anion equivalents or d reagents . 

Whether to consider these heteromolecular associates as real chemical adducts is more terminology than a chemical problem. In most cases investigators truly assume that in systems formed of two alcohols or of two carboxylic acids, specific interaction does not exist. In the case of mixed solvents formed of two carbon acids, that is true only when components have similar proton affinity, as is the case of a system such as acetic acid-propionic acid (see further paragraph 9.2.8).
