I am going to prepare the Adduct of anthracene and maleic anhydride,where animal charcoal is generally used.I am going to use coconut charcoal instead of animal one. I need some suggestions.
Coconut derived activated charcoal has a meso-micro porous surface and may not achieve the same adsorption / absorption as the suggested charcoal type. You could consider other plant based carbons, including a peat-based, ones which offer a more meso-macro porous surface. I'm not sure of the role of the activated carbon in the reaction, so take a look into that aspect when considering your options.
Using any porous material in a reaction can provide two types of advantages. Their porosity can offer advantage associated with adsorption or absorption of substrate /product. This has already been mentioned by Doughty in his answer earlier. The other advantage is the presence of any catalytic sites.
The composition of charcoal depends on the raw material and its content. As for example, animal charcoal produced from bones is likely to contain a lot of Ca and Mg phosphates.
I prepared the Adduct of anthracene and maleic anhydride many years ago in excellent yield in dry refluxing toluene without needing animal charcoal or coconut charcoal.
The objective/purpose for the use of charcoal in this particular reaction, has not been disclosed. So general information about charcoal is being provided in the form of answers to this question. Based on this Haloi might be able to make his choice.
