I need to present this in a helpful and informative way without being pushy. Make sure the response is clear and provides actionable steps for the user to find a legal copy.

I should also mention the importance of supporting authors by purchasing the book if possible, and if not, to seek legal means. Maybe the user can find used copies or access through libraries. Also, checking government or university websites for free educational resources.

Another angle is to suggest alternative resources. Are there open-access textbooks on Industrial Chemistry? Maybe other online courses or free articles could help. For instance, MIT OpenCourseWare or other educational platforms might have relevant materials.

I should also consider that the user might not have access to the physical book or can't afford it. Maybe there are legal alternatives they aren't aware of. I should suggest those. For example, checking if the book is available in PDF format through the publisher's website. Maybe the publisher offers a sample or an open-access version. Also, academic institutions sometimes provide access to such books through their libraries.
