Acetone, also known as propanone, dimethyl ketone, 2-propanone, propan-2-one, dimetilformaldehida, and β-ketopropana, is a liquid compound that is colorless and flammable. It is the simplest ketone. Acetone is soluble in a variety of comparison with water, ethanol, diethyl ether, and others.
He himself is also an important solvent. Acetone is used to make plastic, fibers, drugs and other chemical compounds. In addition chemicals to industrially manufactured, acetone can also be found in nature, including the human body in a tiny womb.
At first Cumene Cumene hydroperoxide with Oxidised be atmospheric air or oxygen-enriched air in one or several oxidation. The temperature chemicals used is between 80 C - 130 C with 6 atm, sertadengan chemicals addition of Na 2 CO 3. This oxidation process is generally carried out in 3 or 4 reactors in series.
The results of the oxidation of the first reactor Cumene hydroperoxide containing 9-12%, 15-20% in the second reactor, 24-29% chemicals in the third reactor, and 32-39% in the next reactor. Then the fourth reactor product evaporated to a concentration of 75-85% Cumene hydroperoxide into. Then with the addition of the acid cleavage reaction will occur Cumene hydroperoxide into a campuranyang consisting of phenol, acetone and various other products such as chumylphenols, acetophenone, chemicals dimethyl phenylcarbinol, a-Methylstyrene, and hydroxyacetone.
The mixture is then neutralized by the addition chemicals of sodium phenoxide or other alkaline ion exchangers or with others. Then the mixture was separated and the crude acetone obtained by distillation. To obtain the desired purity necessary addition of one or distillation column.
If you use two columns, the first column to separate chemicals impurities such as Acetaldehyde or Propionaldehid. While the second chemicals column is used to separate the heavy fractions are composed mostly of water. Acetone was obtained as a result of the second tower (Kirk & Othmer, 1991).
Propylene oxidation chemicals process becomes Acetone can take place at a temperature of 145 C and pressure of 10 atm in the presence of bismuth phaspomolibdat on alumina. In this process chemicals comprises the reaction product of acetone and Propanoldehid (Kirk & Othmer, 1983).
In the process of making this Acetone, Isopropyl Alcohol mixed with air and used as bait reactor operating at a temperature of 200 C - 800 C. The reaction can be run by either using catalysts chemicals such as those used in the dehydrogenation process of Isopropyl chemicals Alcohol.
This reaction is highly exothermic (43 kcal / mol) at 25 C and it is necessary to control the temperature very carefully chemicals to prevent the resulting decline chemicals in yields. To get a good conversion reactor is designed so that the desired results can be immediate. The process is rarely used when compared with the dehydrogenation process (Kirk & Othmer, 1983).
In this process Isopropyl chemicals Alcohol is evaporated by vaporizer and heated in HE by using steam and then put in a multi-tubular fixed bed reactor. There are a number of catalysts that can be used in this process chemicals is a combination of zinc oxide-zirconium oxide, a combination copperchromium oxide, copper, silicon dioxide. The reactor operating conditions is 1.5-3 atm and a temperature of 400 C-600 C.
With this conversion process can reach 75-98% and the yield can reach 85-90%. Gas heat out of the reactor consisting of Isopropyl Alcohol, Acetone, chemicals and hydrogen is passed scrubber, the gas to be separated between chemicals insolubl e (H2) with acetone, isopropyl alcohol, and water.
The results of this scrubber is distilled, Acetone taken as a result of the above, while a mixture of isopropyl alcohol and water as the bottom. The results below are distilled again to recovery Isopropyl Alcohol taken as a result of the above which is then recycled to the reactor (Kirk & Othmer, 1983).
Chloroform is an organic compound is a liquid with a boiling point of 61.2 0 C, the refractive index of 1.487 and odor, as well as volatile. In Dictionary of Chemistry (2002: Balai Pustaka) chloroform is a colorless liquid with a sweet odor, pleasant and anesthetics. In daily life serves as a tranquilizer chloroform, and the organic compound solvent. According Riawan (1990), chloroform (CHCl 3) can be used for fat solvent, "dry cleaning", dope. For drug use spiked with ethanol, stored in brown bottles, chemicals filled to the brim.
Chloroform can be made via the electrophilic substitution reaction H atoms ά all carbonyl compounds bergugus acetyl (CH 3 CO-) in alkaline conditions. Materials can also be used when the alcohol is oxidized generating an acetyl group.
Chloroform was originally used in medicine as a anastesik. However, chloroform is easily oxidized in the presence of u
