Short reaction notes:
Used a similar ratio of 365g distilled benzyl chloride with 450g powdered hexamine.
Added 1000ml water, and heated to 100degC for 4 hours
Then added 120ml 30-35% HCL and refluxed for 15 minutes
Then let sit for about 30 minutes and again added 100mls more HCL: so that pH acidic.
Briefly reheated to reflux and then cooled.
Extracted organic into DCM, evaporated DCM
Added lots of water to the flask, and steam distilled the resulting benzaldehyde by dsitilling the water from the flask.
