Chemical compounds having a boiling point in the range between 40 C° below and 20 C° above the boiling point of meta-xylene, and possessing oxygen, nitrogen, or halogen atoms in their molecular structure were considered as possible en-trainers. Thirty-six such compounds were evaluated. The ...
Tissue-section paraffin was removed by submerging in xylene at RT for 5 min. Tissue sections were then hydrated by serial passage in dilutions of ethanol (100%, 95%, 70%, and 50%) at RT for 5 min and rinsed with distilled water. Reovirus antigen in tissue sections was retrieved ...

They can therefore be used in chemical reactions which proceed especially advantageously in such solvents, for example metallorganic reactions...
Suitable auxiliary substances for this purpose are essentially: solvents such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. mineral oil fractions), alcohols (eg. methanol, butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine, dimethylformamide) and...
