Uranus and Neptune “poisoned” by acid of Hitler”

Exotic carbonic acid, which is also called “acid Hider” may be part of the depths of Uranus, Neptune and the icy satellites of the giant planets, found out by chemists from MIPT and Skoltech Artem Oganov and Gabriele Saleh. The corresponding article was published Friday in the scientific journal Scietnific Reports.

Scientists have known that at atmospheric pressure all compounds of carbon, hydrogen and oxygen in addition to methane, water and carbon dioxide is thermodynamically unstable. With the help of computer simulation was able to show that at high pressures typical of depths of planets, the formation of exotic crystalline and polymeric compounds – including coal and alcoholyou acid.

“Gas giants “middle class” – Uranus and Neptune – mostly made up from carbon, hydrogen and oxygen. We found that at pressures of several million atmospheres in the subsoil should be formed joints, impossible on earth,” says the study’s lead author Artem Oganov, head of the laboratory of computer design of materials at MIPT and Skoltech Professor.

The authors cite the example of how with the growth pressures up to 44 GPA carbonic acid becomes a polymer, which remains stable at least up to 400 GPA (or 4 million atmospheres). In addition, when 314 GPA becomes possible exothermic reaction between carbonic acid and water with the formation of orthogonal acid (H4CO4). This compound has been limited to laboratories due to its extreme instability. The structure of the molecule ortogonal acid resembles a swastika, why it is jokingly referred to as “acid of Hitler.”
