We’re sorry, but the industry you have selected is not currently available in your chosen language. A model that represents the methylated groups of the surface of Aerosil R is proposed, and it is suggested that the adsorption of isobutene takes place in the region where there are hydroxyl groups.

For reproduction of material from all other RSC journals and books: In the latter, the heat of adsorption remains constant, while the quantity adsorbed on the monolayer decreases, and is proportional to the part of the surface that is free of methyl groups and contains hydroxyl groups.

XX is the XXth reference in the list of references. If the material has been adapted instead of reproduced from the original RSC publication “Reproduced from” can be substituted with “Adapted from”.
