C4H10 + 61/2O2 → 4CO2 + 5H2O

ΔH = −2.8781 - −2.8769 MJ mol−1

Is that a formula to heat drinking water?

It is a formula to produce the heat for drinking water.

If you knew precisely what you were doing and had the right measuring equipment you could combine sodium hydroxide and hydrochloric acid. This will cause an exothermic reaction and could bring the water to a boiling point if enough of the acid/base materials were used. The result would be salty water. It would be drinkable, but you'd have to remove the salt (somehow) if you needed this water to survive on.

A better option would be to keep the two sets of liquids separated. Put the water you want to drink into a bottle and tightly seal it, then place this into the vessel where the chemical reaction takes place. Once the reaction is done remove the hot bottle with tongs, carefully uncap it, and pour out the clean hot water.

See I have an idea but the product has to be safe and easy enough for consumers. Like your everyday soccer mom even.

My advice is to consult with the FDA. They will be more than happy to point out the folly of chemically treating water and then having them approve it for human consumption.

Stick with a safer solution.

... And let us not forget, that putting a kettle of water over an open flame is indeed a chemical way of heating water.

Yes, fire is a chemical reaction...

Sort Of Heating Water Chemically

08/24/2012 11:26 AM

Is your idea something along the lines of a flameless ration heater already in use by people around the world to heat water and food?

Will water that is microwaved with 12V kill you, too?

Soccer moms will love this.↓ This will give them yet another distraction, while driving the kids to the soccer match.

Yeesh! 660 watts @ 120VAC, 240 watts @ 12VDC... 20 amps @ 12VDC?

So... does it come with a carton of fuses? How long would it take to boil a cup of water at 240 watts? Can you water the plants with water boiled (eventually) in a microwave powered at 12VDC?

I dont mean to be secretive. but its something that noone is using yet and it has the potential to be very big and very profitable. Does anyone know how i would go about getting a patiant?

How about a PATENT instead of a patiant?

Hhhmmm, you appear to starting off on the wrong foot here.

Do you have formal training in science or engineering?

It's wonderful that you have a great idea.

You will discover, however, that being a smart*%# with an attitude will get you nowhere in these forums.

As you have seen, people have offered suggestions and help.

Chill a bit, and you'll see that things will be easier on you, and the help will come.

Why boil the water to make it potable?

Off the shelf water purifying tablets would do it. Easier and safer than carrying around reagents just waiting for the chance to get it on together in a blistering tango.

ETC ETC

Self heating soup, tea and coffee have been featured in movies. The same method will heat water.

These one use the heat of hydration when you slake lime in an inner compartment to heat the soup/tea/coffee in 3 minutes.

How about gamma irradiation? If that is not heating the water quick enough, you can even try UV with excess flux. How much heat do you want?

Hi RobTech, I think there is a way to do all this process indeed chemically : there is supposed to be such a thing/process in Japan where they heat sake this way. Never bothered to check out-maybe you will invest some time? Best regerds and luck.

all the ways to heat chemically keep the food separated from the heating method. Here are some methods and diagrams to show assorted ways. Click on any diagram and close the picture to read the base page and then use the back arrow for the next one.

If you neutralize an acid and a base the products must be edible, as in salt from HCL and NaOh, but to use enough hydrochloric acid and sodium hydroxide to neutralize and give a hot drink item would leave it too salty to drink.

other acid base pair would be very toxic. NaF and NaOH for example.

an acid base pair in the heating capsule would work and would make more heat than the CaO - water heating capsule, but dry lime and water are easy to contain with little risk of corrosion caused leakage. And strong acid and base combination would require some corrosion resistance in the encapsulating means = $$ as well as risk.

Any self combusting heating wick would make toxic fumes

Calcium oxide could be mixed with an excess of highly carbonated water.

The result would be heated water with some calcium carbonate and a little calcium bicarbonate.... effectively heated hard water.
