Abstract

527,316. Alcohols. DU PONT DE NEMOURS & CO., E. I. April 4, 1939. No. 10535. Convention date, April 5, 1938. [Class 2 (iii)] In a process for the production of alcohols by the direct catalytic hydration of olefines in the presence of an aqueous solution of a mineral acid, e.g. sulphuric acid, a dilute alkaline solution is introduced into the alcoholic vapours leaving the reaction zone in such proportion that the crude condensate obtained on cooling the vapours has a pH value not substantially lower than 6.0. Corrosion of the apparatus by the crude products is thereby prevented, and undesirable impurities are removed. The process is particularly applicable to the production of ethyl and isopropyl alcohols from ethylene and propylene. In the plant shown, ethylene, compressed by a pump 2, is passed from a pipe 1 to a pipe 4, where it is mixed with water from pipe 20 and with recirculated ethylene from pipe 19. The mixture then passes through section 5 of a heat exchanger 6, where it is heated by the hot reaction products passing countercurrent through the section 12 of the heat exchanger. Additional heat is supplied by a heater 8, and the mixture of ethylene and water vapour passes to the reaction chamber 10, where it comes into contact with aqueous sulphuric acid. The reaction products pass from the chamber 10 through pipe 11, where they are mixed with dilute alkali solution from a tank 28, and then through section 12 of the heat exchanger to a water cooler 14, from which the unreacted ethylene and condensate pass to a high pressure separator 16. The ethylene is returned to the process through pipes 17 and 19, and the condensate passes through pipe 17A and valve 23, where the pressure is reduced to atmospheric, to a low pressure separator 25. The gas released in the latter is chiefly ethylene, and may be removed through pipe 27, purified and returned to the hydration process. The crude condensate is withdrawn through pipe 26 and rectified.
