Conjugated acid oils

Owiag to incomplete halogea absorption, iodiae values for conjugated acid oils by the usual methods (Wijs, Hanus, etc) are both low and variable. The tme value of fresh tung oil, as determined by a special method (13), is 248—252 that of oiticica oil is 205—220.

In mineral and synthetic engine oil formulations, hydrogen bond formation between anionic or molecular bases (A, B) and their conjugate acids HA or BH+, have a heavy impact on the activity of acids and their salts. For example, in mixtures of carboxylic acid with excess of sodium carboxylate in hydrocarbon and aprotic solvents, the activity of the acid is greatly decreased because of homoconjugation ... 

Carboxylic acids and phenols R(CH2)nCOOH, ArOH, and cationic R(CH2) NH3+ conjugated acids exist in engine oil formulations together with their own or different bases, and will interact to form hydrogen-bonded complexes (Fox et al., 1991b). 

The rate equation with strongly acidic catalysts is also second order in silanol and first order in catalyst (75). The mechanism is proposed to proceed via protonation of silanol, followed by an electrophilic attack of the conjugate acid on nonprotonated silanol. The condensation processes outlined in reactions 16a and 16b for sulfonic acids is also an applicable mechanism for the acid catalysis. The condensation polymerization in emulsion catalyzed by dodecylbenzenesulfonic acid is second order in silanol, but the rate has a complex dependence on sulfonic acid concentration (69). This process was most likely a surface catalysis of the oil-water interface and was complicated by self-associations of the catalyst-surfactant.

Azulenes, which are intensely blue, can be extracted from petroleum ether with 62% sulfuric acid as the colorless conjugate acid sulfates. Corresponding salts with picric acid, which are intensely colored, are useful for isolation of the hydrocarbons. Thus the guaiazulene present in an oily mixture obtained by dehydrogenation of technical guaiene with sulfur can be isolated by treating the oil with a hot saturated...
