Hey, just thought I'd ask for some suggestions right now to help with a recent project.
I need a portable way to produce heat, ideally by a 'heat pack' type of device with a chemical reaction, that would reach 120 to 170 degrees C. Does
anyone have any ideas?
I was thinking the two reagents would be suspended or dissolved in dryish glycerin (which boils at over 200 C), and could be poured together to react
and produce heat. CuReUS - 9-3-2017 at 22:23

Great idea thanks. Alkemist - 10-3-2017 at 15:03
A potential issue with ration heaters is that they only gonna reach 100 c....If you need a temp range of 120c-170c these obviously will not suffice.
I assume you suggested glycerine so as to be able to achieve Temps higher than 100c? Perhaps a little more info such as its intended use we could be
of more help. Is toxicity of concern? Etc.Daffodile - 11-3-2017 at 11:37
Toxicity is not a concern, I just need a portable method pf heating a volatile liquid without using flame.CuReUS - 11-3-2017 at 11:50

How do you know they will reach only 100'C ?
Because the reaction boils the heat pack water.
What I meant was,why would it not go any higher than 100'C.But I get it now.The reaction needs water to run,so if the water boils off,it will stop.A Halogenated Substance - 22-3-2017 at 09:39
There is a video on sodium acetate raising the temperature of water upon recrystallizing:
I don't think it's gonna get a heat pack up to 100 degrees Celsius though.
If toxicity isn't a concern then why not just combine sodium hydroxide or concentrated sulfuric acid with water?Liamatpm - 23-3-2017 at 02:34
Could you make a container with cut up the heaters and then you can add water. So you might have to add water to have the correct temp. This works in
my head, it might not work in practice.
