Circulating steam distillation apparatus and process for extracting methylcyclopentadienyl manganese tricarbonyl by aid of apparatus

Abstract

The invention relates to a circulating steam distillation apparatus and a process for extracting methylcyclopentadienyl manganese tricarbonyl by the aid of the apparatus. The apparatus comprises a distillation kettle, a condenser and an oil and water separator, a heating system and a stirrer are arranged in the distillation kettle, a condensed water overflow pipe is connected between the distillation kettle and the oil and water separator, a lower discharge outlet of the oil and water separator is connected with a liquid seal pipe, and a pressure balancing pipeline is connected among the liquid sealing pipe, the oil and water separator and the condenser. The process includes adjusting the height of the liquid seal pipe and the height of the condensed water overflow pipe; filling materials and water into the distillation kettle; stirring, distilling and cooling the materials; and performing reflux and separation of water and oil by the oil and water separator. The device and the process have the advantages that useful components such as the MMT (methylcyclopentadienyl manganese tricarbonyl) can be recovered to the greatest extent, high methylcyclopentadienyl manganese tricarbonyl recovery rate can be realized, the difficult problem of coking of a distillation kettle used in a traditional rectifying process is avoided, and large quantities of fresh water and energy can be saved as compared with an existing steam distillation process.

AI Technical Summary

Benefits of technology

This new design for an apparatus called this inventor's cycle steam distiller (CWS) improves upon existing methods like conventional steam distills because it does away with any unnecessary steps or materials that are added during processing instead relying on evaporation techniques. It also includes various technical features including improved efficiency, reduced power consumption, automatic control over process variables, efficient recovery of residual liquid after cleanings, effective removal of harmful substances without causing damage to equipment, environmentally friendly disposal options, etc., resulting in significant benefits compared to current technologies.

Problems solved by technology

Technologies described in this patents involve separating materials based on specific properties such as size, shape, density, surface tension, hydrophility, polarity, melting points, and boiling range. However, current methods require multiple steps involving different techniques like steaming, cooling downstream, and refluxing before further processing. Additionally, traditional processes consume significant quantities of power while also producing unwanted side effects including pollution issues associated with disposers used for washing away nonvolatiles present within the product stream.
