Description
The present invention relates to a kind of pharmaceutical synthesis plant, more particularly, relates to organic raw material methylated ethanol production plant.
GENERAL BACKGROUND
Methylated ethanol is an important organic chemical raw material, which can be used in the manufacture of acetamide, acetoacetate, methyl heptenone and so on. It is widely used in flavors and fragrances, paints, pharmaceuticals, advanced inks, pyroclastic cotton, nitrocellulose, dyes and other industries. It is one of the largest amount used synthetic perfumes in food flavor. It is widely used for flavoring food flavor such as banana, pear, peach, pineapple and grapes. It can also be used as extractant and dehydrating agent, as well as used for color printing of food packaging and so on. Tannin extract series of products are used for desulfurization tanning, tobacco material, oil drilling, metal flotation, cleaning and so on. Most of the existing production plant processes are complex. Thus, as an organic raw material, the advantages and disadvantages of production equipment of methylated ethanol have a great economic significant for improving product quality and reducing the by-product contents.
SUMMARY
The purpose of the present invention is to provide organic raw material methylated ethanol production plant, including: stirrer (DI01), stirrer (DI02), transfer pump (Pl01), head tank (VI01), esterification reaction tower (T101), ester distillation tower (T102), stratification device (VI02), partial condenser (E101, El03, El05), total condenser (El02, El04, El06), mixing coil (El07), ester drying tower (T103); among them, esterification reaction tower (T101) is connected respectively to partial condenser (E101) and ester distillation tower (T102), stratification device (V102) is connected respectively to mixing coil (El07) and ester drying tower (T103); among them, inner pot diameter of stirrer (DI02) is 600-700 mm, impeller diameter of
2018101841 28 Nov 2018 transfer pump (P101) is 115-120 mm, tube inside diameter of mixing coil (E107) is 0.013-0.014 m.
Organic raw material methylated ethanol production plant, the production process is: added acetic acid and excess azeotropic point of ethanol into mixing tank D101, stirred and mixed, pumped into mixing tank D102, added sulfuric acid in mixing tank, stirred to fully contact. Pumped into head tank, preheated by reflux condenser E101 at the top of esterification reaction tower T101, entered the tower. The tower is heated directly by steam. The reaction is continuously carried out in the tower. The produced ester and water as well as the unreacted alcohol are distilled off from the top of the tower at 80 °C. The bottom of the tower discharges the wastewater containing sulfuric acid. The steam is divided and refluxed by the partial condenser E101. The remaining condensate and condensate in total condenser are mixed and entered into ester distillation tower T102. This tower is an ordinary distillation column using indirect heating. The top temperature of the tower is 65-67 °C. It steams out ternary azeotrope of ester, alcohol and water. Added cold water before azeotrope entering into mixing coil El07, then mixed and cooled, separated by separator V101 into the upper and lower two liquid layers. The lower contains a small amount of ester and alcohol, returning to the ester distillation tower T102 for recovery; the upper is the ester-containing crude ester, pumped into ester drying tower T103, and obtained the finished product at the bottom of the tower. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
