Making Trioxane from Formaldehyde

We are looking for a chemical engineer to come up with a new innovative way to make Trioxane from Formaldehyde with the shortest possible reaction time and with the lowest number of process steps. The process should also be done using temperatures under 100 - 120 degrees celsius and the reactions must be carried out at atmospheric pressure or at a maximum of 3- 5 bar. If you think you are capable of taking on this challenge then please contact us, we are working on an environmentally beneficial project that helping towards our fight against climate change.
