What is involved in acetone production?

most acetone production around the world since 2011 has been done through what is called the cumuna process, the hydrolytic reaction of cumental hydroperoxide. In this way, more than 90% of acetone production is generated and includes a reaction between plastic propylene and aromatic benzene compound. The output of both chemical compounds is phenol and acetone and for each pound (0.45 kilograms) of phenol produced by a reaction, approximately £ 0.62 (0.28 kilograms) of acetone is formed. Some acetone is also generated from a deyhdrogenic reaction process including isopropyl alcohol or direct hydrogenation of various hydrocarbons.

The Kumen process for acetone production was first discovered by Rudolf Yur'evich Uldris in 1942 and the production of acetone in 1949 in 1949 in Russia and Canada. In 1953, 8,000 metric tons were generated in Canada a year, and by 2002 the US itself produced 1,839,000 metric tons of chemicals. Commercially with 75% acetone produced in the US uses to produce other chemicalsThe 12% is used as a universal solvent and the remaining 13% has different purposes, from the production of adhesives to the pharmacy.

Cumen chemical reaction is a relatively simple process. The Kumen, which in itself is a solvent, is derived from benzene propylation and then oxidized for the formation of cumental hydroperoxide. The reaction takes place in water -based emulsion containing sodium carbonate, at _{2 3 , at £ 194 to £ 266 ° Fahrenheit (90 ° to 130 ° Celsius) and pressure £ 145 per square inch (5 to 10 bar). The oxidized state of the cuMun as a cumental hydroperoxide then concentrates in vacuum columns, where it is used to separate the intake process of cleavage or division of covalent molecular fenol and acetone.}

acetone production that includes the use of isopropyl alcohol requires a combination of i-propyl alcohol with water and steam in evaporation koThe sea that is heated to a temperature where all chemicals react. The reaction is facilitated by circulation of compounds in turbulent flow and useful products of reaction are acetone and hydrogen. The waste created in response includes water and some i-propyl alcohol. The acetone is then separated from the hydrogen gas in the production of washing machine and acetone in this way leads to 99% of the volume cleanliness.

Although acetone can also be generated by bacterial fermentation processes or dry distillation of acetates, the comania process has dominated since 2011. This is because the input chemicals for the benzene and propylene process are considered somewhat cheap, abundant combinations. In contrast, phenol and acetone are valuable industrial chemicals used in millions of tons around the world in the 21st century.
