@S_T_Work unfortunately Acrobat isn't built that way, but there is a slight work-around, to kinda get what you have in mind, and you can try this is by opening the same PDF document in two separate Acrobat windows. This isn't a "built-in split function" in the way some other applications might offer a custom vertical split, it's the most effective workaround in Acrobat Pro for achieving independent, side-by-side comparison of different sections within the same large PDF, which sounds precisely like what you need for efficiently identifying and removing those specific pages.
Okay... Open your PDF document in Adobe Acrobat Pro. Go to Window > New Window. This will open a second, entirely independent window of the exact same PDF file. Now you WILL have two separate Acrobat windows, both displaying the same document. You can arrange these windows side-by-side on your screen (drag one to the left edge, one to the right, or manually resize them). You will need to adjust the width of the windows to fit on your screens. Each window can be navigated independently. You can scroll to page 5 in one window and page 20 in the other, and both will stay exactly where you left them. You can zoom in differently on each as well. Any edits you make in either window will apply to the single underlying PDF file.
