WebJun 1, 2015 · Phosphoric acid is a tribasic acid with the structure shown in Scheme 1. The p Ka of the acidic groups are as follows: p Ka1 = 2.15, p Ka2 = 7.09, p Ka3 = 12.32 [2]. H 3 PO 4 is usually available as an 85% aqueous solution. It can be prepared from its anhydride. WebJan 28, 2015 · The same reaction occurs with simple alcohols to produce the corresponding metal alkoxide and hydrogen gas 2 M + 2 R O H 2 M O R + H X 2 As you increase the hydrocarbon portion of the alcohol, or reduce accessibility to the O H portion of the alcohol ( e.g. make the alcohol less like water), you slow down the rate of the reaction.
WebThe reaction allows some selectivity, because it is possible to remove only one of the benzylic groups to give an alkylbenzyl phosphoric acid. The limitation of this process is the relative instability of dibenzyl phosphochloridate; at low temperatures, where the compound is stable, reactivity is low. WebDec 10, 2024 · Carboxylic acids occur widely in nature, often combined with alcohols or other functional groups, as in fats, oils, and waxes. They are components of many foods, medicines, and household products. Not surprisingly, many of them are best known by common names based on Latin and Greek words that describe their source.
