(Video) Sugar dehydration - an alternative to the use of concentrated sulfuric acid


I was digging through ACS Publications a few days ago and ended up finding the article "Sugar Dehydration without Sulfuric Acid: No More Choking Fumes in the Classroom!" written by Todd P. Silverstein and Yi Zhang. It is an alternative to perform the classic demonstration of dehydration of sugar, in which concentrated sulfuric acid is generally used. The version presented in this paper suggests the use of potassium chlorate and alcohol. I tried it and it was really fun, so I decided to make a video.

The video is here: https://youtu.be/64IlI79xWoE

Looks a bit like when i was young and mixed KNO3 and common sugar and set it on fire.
I soon found out that when its confined like in a sealed tube with a hole and a Christmas sparkler as a fuse through the hole it explodes.
Very dangerous, sent metal shrapnel in every direction, quite lethal.
I also made a hole in our garage door from a explosive experiment, something my dad wasn't too happy about.
But it got me interested in chemistry, that´s a positive thing.
