A question: could anyone help verify this using ASPEN?

Thread Content

As the title suggests, I am an engineer working on pilot-scale experiments in fine chemicals. I’m dealing with a reaction in which benzyl dichloride (CAS 98-87-3) reacts with water; the reaction is to take place in a 1:1 molar ratio. However, it might be difficult to achieve uniform mixing, so I plan to use a 1:1 weight ratio instead. At high temperatures, benzyl dichloride hydrolyzes to form benzaldehyde; what is the relationship between the reaction rate and temperature (such as 120°C, 150°C)? Can ASPEN provide a preliminary estimate? Also, how about the heat release? My estimate is that 99 kJ of heat is generated for every 1 mol of benzyl dichloride consumed; taking into account the exothermic reaction of hydrogen chloride dissolution, the value is estimated to be around 170 kJ/mol. Could some expert please take a look and see if this reaction is possible?

The relationship between reaction rate and temperature is a kinetic problem; Reaction heat and temperature are thermodynamic issues.

It seems that this Aspen can’t solve it; maybe a Gibbs reactor could be tried

Dear experts, may I ask if this reaction can be carried out in a tubular reactor? Are there any things to be careful about with tubular reactors?
