EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains‚ and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids‚ each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which‚

1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA

Folic Acid is a B vitamin‚ specifically B9. It is an essential nutrient required by the body to create healthy new cells. While we hear about it mostly in regards to pregnancy‚ it is important to understand that the need for folic acid goes even beyond this. Folic acid is essential for the body to create red blood cells which in turn prevents anemia. It is also plays an important role in the metabolism of homocysteine‚ an amino acid. The recommended dietary allowance (RDA) for all men and women

| An acid is a chemical substance any of various typically water soluble and sour compounds that are capable of reacting with a base to for a salt‚ that redden litmus paper‚ that evolve hydrogen on reaction with various metals‚ that in water solution yield hydrogen ions‚ and that have hydrogen containing molecules or ions able to give up a proton to a base or that are substances able to accept and unshared pair of electrons from a base. An alkaline is a chemical compound that neutralizes or effervesces

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance
