Chemistry News. Study Paves the Way for New Photosensitive Materials Apr. 22, 2021 — Scientists are investigating the molecular dynamics of titania clusters. Such research is a basic step toward the development of more efficient ... Silver Ions Hurry Up, Then Wait as They Disperse. Aldehydes and Ketones. Drinking methanol is harmful, not because of the CH 3 OH molecule s themselves, but rather because the human body converts these molecules into methanal (formaldehyde) molecules by combination with oxygen: Formaldehyde, H 2 CO, is very reactive—in the pure state it can combine explosively with itself, forming much larger molecules.
Consequently it is prepared commercially as a water solution , formalin, which contains about 35 to 40 percent H 2 CO. Formalin is made by combining methanol with air at 550°C over a silver or copper catalyst . It is used as a preservative for biological specimens, in embalming fluids, and as a disinfectant and insecticide—not a very good substance to introduce into your body.
