Very low temperature formaldehyde reactions and the build-up of organic molecules in comets and interstellar ices
We have investigated thermally promoted reactions of formaldehyde (H 2CO) in very low temperature ices. No such reactions occurred in ices of pure formaldehyde. However, addition of trace amounts of ammonia (NH 3) were sufficient to catalyze reactions at temperatures as low as 40 K. Similar reaction...
