A process of dissolving [6,6]-phenyl-C.sub.60-butyric-N-2-dimethylaminoethyl ester in a solvent to produce a first mixture. A reagent is added to the first mixture to produce a second mixture. The second mixture is then refluxed to produce [6,6]-phenyl-C.sub.60-butyric-N-2-trimethylammonium ethyl ester iodide.

The present invention is directed to a method of producing active pharmaceutical ingredients (APIs). The method includes subjecting a reaction mixture with an API precursor to solvent extraction to produce a reactant stream with the API precursor. The method includes concentrating the API precursor in the reactant stream using at least one membrane. The method includes carrying out a reaction in a membrane reactor. The method includes separating the API precursor from the reaction stream using a separator. The method includes crystallizing the API precursor using a crystallizer to produce APIs.

Poly alkanolamines formed as the reaction products of secondary or tertiary alkanolamines, C8-C24 fatty acids, and shorter chain organic acids are provided, which serve as excellent petroleum/water emulsion breakers for water-in-oil emulsions and reverse oil-in-water emulsions. The polymers are preferably prepared using a reaction mixture of triethanolamine, tall oil fatty acids, and acetic acid.
