A method for the removal of nitrogen compounds from FCC feed or from catalytically cracked distillates including FCC cycle oils by using formaldehyde to selectively couple organic heterocyclic nitrogen species in the FCC feed or FCC distillate to form higher boiling coupling products out of the boiling range of FCC distillate. Removal of the nitrogenous compounds improves the operation of subsequent hydrodesulfurization steps needed for the distillate fraction to conform to low sulfur standards. The formaldehyde is preferably used in the form of paraformaldehyde. The reaction between the nitrogenous compounds in the cycle oil fraction with the formaldehyde is conveniently carried out in the cycle oil pumparound circuit of the FCC main column.

Severely sterically hindered secondary aminoether alcohols are prepared by a process comprising reacting a ketene with sulfuric acid to produce an anhydride which is then reacted with, to cleave the ring of, a dioxane to yield a cleavage product which is then aminated using an amine, followed by hydrolysis with a base to yield the desired severely sterically hindered secondary aminoether alcohol.

Synthesis of severely sterically hindered secondary aminoether alcohols from a ketene and/or carboxylic acid halide and/or carboxylic acid anhydride

Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.
