The present invention provides a method for producing sucralose from a
feed stream including a sucrose-6-acylate in a reaction vehicle. The
method includes: (i) reacting the sucrose-6-acylate with a chlorinating
agent in order to chlorinate the 4, 1' and 6' positions of the
sucrose-6-acylate; (ii) quenching the product stream of (i) with an
aqueous solution of a base to provide a sucralose-6-acylate and the
chloride salt of said base, wherein the concentration of the aqueous
solution of the base is sufficiently high such that at least a portion of
the chloride salt of the base is formed as a precipitate; (iii) either:
deacylating the sucralose-6-acylate by treating the product stream of
(ii) with a base and thereafter removing precipitated salt to provide a
product stream including sucralose; or: removing precipitated salt from
the product stream of (ii) and thereafter deacylating the
sucralose-6-acylate by treating with a base to provide a product stream
including sucralose; and (iv) isolating sucralose from the product
stream of (iii).
