WebConversely, polyphosphoric acids or polyphosphates are often formed by dehydrating a phosphoric acid solution; in other words, removing water from it often by heating and evaporating the water off. Phosphate and phosphite esters The -OH groups in phosphoric acids can also condense with the hydroxyl groups of alcohols to form phosphate esters. WebPreparation of Amides. Amides can be prepared from acyl chlorides, esters and carboxylic acids. The most straightforward should be the reaction with acid chlorides since they are the most reactive carboxylic acid derivatives and amines are good nucleophiles too: Esters are not as reactive as the acid chlorides and therefore, more forcing ...
