Question

How estimate mono alkylphosphate, dialkyl phosphate & free h3po4 in phosphate esters?

Answer 1

Answer:

Acetoacetate Ester Synthesis

The Claisen condensation of ethyl acetate yields ethyl acetoacetate. This readily available compound and other β-keto esters formed by Claisen condensations are used as intermediates on the synthesis of alkyl derivatives of ketones. For example, ethyl acetoacetate is like an acetone molecule with an appended ester group.
