lets say swim wanted to dream up some methylamine. but his paraformaldehye contained some blue tint. could he continue on? would there be problems goint the b/s route? or should he get rid of the tint somehow? How?

It looks and smells like para..but its definately not 100%. The blue dye can be partially washed out with alcohol or water..but it will still have a tint..and you will find when you go to use it..it wont fully dissolve. The best option here (if you have NO other alternatives) is to subliminate it in a filter flask. Direct the gas into cold distilled water. Even doing this you will probably only get a 25% yield. I think they use formaldehyde in ponds to control bacteria or something.

Do a search on blue paraformaldehye. Someone else had run into this problem awhile ago. No bad results if Swim remembers right.

Wouldn't it be easier to just buy a couple gallons of formaldehyde from an online chemical supplier? I don't believe it's watched
