Abstract

Process for the separation of salts of new aromatic mono-esters from sulfuric acid, characterized in that it is a diphenol corresponding to the following general formula: ** (See formula) ** wherein R1 represents a hydrogen atom or an alkyl group and R2 represents an alkyl group or a 2-pyridyl group, or R1 and R2 together to the carbon atom, to which they are attached, represent a phthalide group. ** (See formula) ** in essentially anhydrous conditions with chlorosulfonic acid in the presence of an acid acceptor at a temperature between 0º and room temperature; The mixture is poured into water/ice, the acid acceptor being removed by extraction of the basic mixture, the starting diphenol which has not entered the reaction by extraction at a pH comprised between 7 and 9 being removed from the aqueous solution and obtaining thus the salt of the new mono aromatic ester by dry concentration of the solution at low temperature and at reduced pressure by extraction of the salt obtained with an organic excess and then it is crystallized; its chemical constitution is the following ** (See formula) ** where Me means an inorganic cation.
