The phrase "acidic additive" is correct and usable in written English.
It can be used in contexts related to food, chemistry, or manufacturing where a substance is added to enhance acidity or preserve food.
Example: "The recipe calls for an acidic additive to balance the flavors and enhance the overall taste of the dish."
Alternatives: "sour ingredient" or "tart enhancer".
18 Three control experiments with allenyne 1 d and the corresponding deuterium-labeled allenynes [D2]- 1 d and [D6]- 1 d were conducted under palladium catalysis in the absence of any additional basic or acidic additive and using DCE as the solvent (Scheme 3).
Acetic acid (AcA) was selected as acidic additive for the optimization step since it could lead to the enantioseparation of more acidic compounds than trifluoroacetic acid (TFA) and formic acid (FA), while among the three basic additives tested, diethylamine (DEA) most often gave better results with respect to enantioresolution and selectivity than butylamine (BuA) and triethylamine (TEA).
Add another acidic additive.
Among the acidic additives, such as trifluoromethanesulfonic acid, p-toluenesulfonic acid and trifluoro acetic anhydride, OTf− showed the best activity in this work.
Therefore, a number of acidic additives were screened and to our delight, we observed that addition of 5 mol % of hydrochloric acid (present in either aqueous solutions or in diethyl ether) or acetic acid led to excellent conversions of the model substrate 1 into 3 (Table 2, entries 1 3).
Most hydroamination reactions have very high activation energies; however, the use of the basic or acidic additives can promote the reaction.
Alternative fermentation methods for grain have become more popular, such as wet preservation with acidic additives.
Acidic additives preserved and even increased the amount of the valuable water-soluble carbohydrates during storage, which affected most significantly the enzymatic hydrolysis yield of maize.
An extensive screening of acidic additives (see Table S2 in the Supporting Information) allowed identification of p-anisic acid as ideal.
Requirements to increase the nutritional value of animal feed and to preserve the carbohydrates during the storage have led to increased research on, for example, urea and acidic additives [ 4, 5].
The potential for nitrobenzene to act as a non-acidic additive was examined, and although improvement of enantioselection was clear, significant decomposition of bromonitromethane was again noted.
