Acid - Wikipedia

An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).[1] The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the

Pyridine synthesis - Organic Chemistry

Recent Literature. Addition of Grignard reagents to pyridine N-oxides in THF at room temperature and subsequent treatment with acetic anhydride at 120°C afforded 2-substituted pyridines in good yields.By exchanging acetic anhydride for DMF in the second step, 2-substituted pyridine N-oxides were obtained, enabling the synthesis of 2,6-disubstituted pyridines.

Carbonic anhydrase - Wikipedia

The reaction that shows the catalyzation of carbonic anhydrase in our tissues is: CO 2 + H 2 O H 2 CO 3 H + + HCO 3 −.The catalyzation of carbonic anhydrase in the lungs is shown by: H + + HCO 3 − H 2 CO 3 CO 2 + H 2 O. The reason for the reactions being in opposite directions for the tissues and lungs is because of the different pH levels found in them.

PROCESS FOR THE PRODUCTION OF TETRABROMOPHTHALIC

To carry out the process of the invention phthalic anhydride is reacted in sulfuric acid solution with bromine and hydrogen peroxide in the presence of a bromination catalyst. Generally it is advantageous to apply the phthalic anhydride as a solution in concentrated sulfuric acid and to gradually add to this solution the bromine and hydrogen peroxide, and next at least partially the bromine.
