Abstract
The invention provides a process for the preparation of monoethylene glycol from sucrose comprising the steps of: i) hydrolysing sucrose to form a reaction product stream comprising glucose and fructose; ii) separating the reaction product stream comprising glucose and fructose into a fructose or fructose derivative rich stream and a glucose rich stream; and iii) contacting the glucose rich stream with hydrogen in a reactor in the presence of a solvent and a catalyst system with catalytic hydrogenation abilities to produce a product stream comprising monoethylene glycol.

A process for the preparation of monoethylene glycol from sucrose comprising the steps of:
- i) hydrolysing sucrose to form a reaction product stream comprising glucose and fructose;
- ii) separating the reaction product stream comprising glucose and fructose into a fructose or fructose derivative rich stream and a glucose rich stream;
- and
- iii) contacting the glucose rich stream with hydrogen in a reactor in the presence of a solvent and a catalyst system with catalytic hydrogenation abilities to produce a product stream comprising monoethylene glycol.
A process for the conversion of sucrose into fructose and/or fructose derivatives comprising the steps of:
- i) hydrolysing sucrose to form a reaction product stream comprising glucose and fructose;
- ii) separating the reaction product stream comprising glucose and fructose into a fructose or fructose derivative rich stream and a glucose rich stream;
- and
- iii) subjecting the glucose rich stream to an isomerisation reaction to provide a further stream comprising fructose and glucose and recycling this further stream is recycled and combined with the reaction product stream comprising glucose and fructose formed in step i).
