Benzene where contained

So much for the plan to get the points on the back boards. Andranik finished on board 6 before both of us and made short work of the game. I don't know the details, but in any case the score was 2:1 against us.

Benjamin was rightly satisfied. He offered a pawn to his opponent and as compensation, he moved in with rook and queen on the seventh rank. So it should probably rather be called "compensation". He was no longer impressed by the 60 DWZ + of his opponent and scored to equalize. 2:2.

Alexander had more difficulties with Black at the beginning of his game, but could free himself by exchanging several pieces. After equalizing positions, Alexander offered a draw on move 23, but his opponent refused.

Benzene in drugs

There are several industrial processes that differ in reaction conditions, process equipment and catalysts. Since p-xylene is technically the most important xylene isomer, selective formation of about 90% of this isomer is sought by using suitable catalysts such as ZSM-5 zeolites.[77]

In the IR spectrum, the phenyl hydrogen vibration appears at about 3,035 cm-1. The C-C valence vibration appears at 1,500 to 2,000 cm-1. At 650 to 1,000 cm-1 are the C-H deformation vibrations.[89]

Benzene burns with a yellow flame to give water and carbon dioxide, and the strong soot evolution indicates the high carbon content of the compound. Motor combustion as gasoline represents quantitatively one of the most important reactions of benzene.
