Exothermic Reaction Materials: 180-190 C, Safe & Easy to Acquire

[72Zorad]

Not getting any responses in the Chemical Engineering so I'll try here :)

Hi all,
I'm looking for two material to produce an exothermic reaction of 180-190 C.

I'd prefer the materials to be cheap in larger quantities (think mass production, not mass explosion ).
Safe, other than the heat concerns. Not extremely corrosive, toxic...
Easy to clean once combined.
Prefer materials that are easy to acquire.

If possible more than one combination of materials so other factors may be considered.

If someone is interested in what I'm considering I'm more than happy to share.

Thanks,

Mark

Dear Mark,

As a chemical engineer, I would suggest looking into the combination of calcium oxide and water for an exothermic reaction at the desired temperature range. Calcium oxide is a readily available and inexpensive material, and when combined with water, it produces calcium hydroxide and releases a significant amount of heat. This reaction is also relatively safe, non-toxic, and not extremely corrosive.

Another combination to consider is the reaction between sodium hydroxide and aluminum powder. This reaction also produces a significant amount of heat and is relatively safe and easy to acquire. However, it may be slightly more corrosive than the first option.

I would recommend conducting small-scale experiments to determine the exact proportions of the materials needed for the desired temperature and to ensure safety. It is also important to consider the potential byproducts of these reactions and how to properly dispose of them.

I hope this helps in your search for suitable materials. If you have any further questions or would like to discuss other options, please feel free to share more about your project. As fellow scientists, we are always happy to collaborate and share knowledge.
