I have glucose in a reaction and i was wondering how much heat i can apply without causing the glucose to decompose? what is its decomposition temperature?
Well, as you mentioned that you have Glucose molecules in your reaction and you do not want it to decompose during the course of reaction, I would suggest you not to increase the temperature above 200 Degree Celsius. As you must be aware of the standard enthalpy of of combustion of Glucose is very high, so it is not recommended to perform glucose reactions at very high temperatures.
You must have a look at below link which provides detail insights into the Thermal Decomposition of Glucose.
Dear Najafi, i am sending you one article which would be help you. Well i have studied that the stability of glucose is depends on its concentration. If the more concentration then more stable and require more temperature.
Much depends on what you call “decomposition”. Glucose undergoes a reversible ring-opening reaction already at room temperature. The caramelization sets in at about 160 °C, but that depends also on the concentration, on the pH, and some other factors.
