Production
3,5-Xylidine is produced industrially by amination of the xylenol using ammonia and alumina catalyst.
gollark: "the Spanish 1.2 beta" sounds much cooler than "Spanish".
gollark: They should start versioning it, too.
gollark: I suppose it's nice that you can go say something like "WHAT? I'm going to talk to the President of Spanish about this" about any issues you might have.

gollark: It doesn't really have a governance structure in place and nobody would accept one.
