Embodiment Construction

[0019] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0020] like figure 1 figure 2 The separation device of hydrochloric acid and polymerized oil in the shown a kind of pinacolone production, comprises separating still 1, hydrochloric acid recovery still 2 and polymerized oil recovery still 3; Said hydrochloric acid recovery still 2 and polymerized oil recovery still 3 are respectively arranged at separation Kettle 1 both sides.

[0021] The side wall of the separation tank 1 is provided with a separation tank liquid inlet 11, a hydrochloric acid liquid outlet 12, a polymerized oil liquid outlet 13 and a discharge port 14; The same side of still 1 and hydrochloric acid outlet 12 are positioned at the below of separation kettle liquid inlet 11, and described hydrochloric acid outlet 12 is connected on the hydrochloric acid ...

Abstract

The invention relates to a separating device of hydrochloric acid and polymerized oil in production of pinacolone. The separating device is characterized by comprising a separating kettle, a hydrochloric acid recycling kettle and a polymerized oil recycling kettle; the hydrochloric acid recycling kettle and the polymerized oil recycling kettle are arranged at the two sides of the separating kettlerespectively. According to the fact that the densities of polymerized oil and hydrochloric acid are different and the density of hydrochloric acid is larger than that of the polymerized oil, mixed hydrochloric acid and polymerized oil stand in the separating kettle to be layered, by arranging a separator at a liquid inlet of the separating kettle, hydrochloric acid and the polymerized oil are quickly separated preliminarily, and hydrochloric acid and the polymerized oil separated from the separator enter the separating kettle to stand and be separated for the second time; through preliminaryseparation by the adoption of the separator and secondary separation through standing and layering, the separating effect of hydrochloric acid and the polymerized oil is better, and the separating speed is higher.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a separation device for hydrochloric acid and polymerized oil in pinacolone production. Background technique [0002] Pinacolone, also known as 3,3-dimethyl-2-butanone, methyl tert-butyl ketone, is an important raw material and organic chemical intermediate for the production of pesticides (fenxiuning, paclobutrazol and other pesticides). Many enterprises use pinacolone Ketones produce pesticides, medicines, dyes and other fine chemical products, and have great application potential in the synthesis of pesticides, especially the synthesis of triazole pesticides. [0003] In the 1970s and 1980s, many research institutions and manufacturers in my country carried out research and development of triadimefon, specific azole, paclobutrazol and other pesticides using pinacolone as raw materials, which caused a climax in the production of pinacolone, and successively developed and perf...
