A waste treatment process and system is described, which finds application in dechlorinating carbohydrates and/or hydrolyzing dimethyl formamide and/or dimethyl formamide in a waste stream. The process includes treating the waste stream with base at a pH of from 11 to 14, and at a temperature of from 200 to 330&#xb0; F.

Waste treatment process

A method for the chlorination of a sucrose-6-acylate to produce a 4,1',6&#x2032;-trichloro-4,1&#x2032;,6&#x2032;-trideoxy-galactosucrose-&#x3b2;-acylate wherein said method comprises: (i) reacting the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide in order to chlorinate the 4, V and 6&#x2032; positions of the sucrose-6-acylate; and (ii) quenching the product stream of (i) to produce a 4,1&#x2032;,6&#x2032;-trichloro-4,1&#x2032;,6&#x2032;-trideoxy-galactosucrose-6-acylate; wherein before said quenching, a portion of the tertiary amide is removed.
